Determine the two z-scores that separate the middle 87.4% of the distribution from the area in the tails of the standard normal distribution. -1.39, 1.39 -1.46,1.46 -1.53, 1.53 -1.45, 1.45
The two z-scores that separate the middle 87.4% of the distribution from the area in the tails of the standard normal distribution are -1.46 and 1.46.
To find these z-scores, we need to first determine the area in the tails of the distribution. Since the middle 87.4% of the distribution is separated from the tails, the area in the tails is 100% - 87.4% = 12.6%. This means that there is 12.6% / 2 = 6.3% in each tail.
Next, we can use a standard normal table or a calculator to find the z-scores that correspond to the 6.3% in the tails. We want to find the z-scores that have an area of 0.063 to the left and to the right of them.
According to a standard normal table, the z-score that has an area of 0.063 to the left of it is -1.46, and the z-score that has an area of 0.063 to the right of it is 1.46.
Therefore, the two z-scores that separate the middle 87.4% of the distribution from the area in the tails of the standard normal distribution are -1.46 and 1.46.

A figure on a coordinate plane is dilated using the rule (6/5x, 6/5y). Tyson says the dilation was a reduction and tashi says the dilation was an enlargement who is correct
The dilation is an enlargement, and Tashi is correct.
How to determine the dilation?To determine whether the dilation (scaling) is a reduction or an enlargement, we need to compare the distances between corresponding points on the original figure and the dilated figure.
Suppose a point P(x,y) is on the original figure. After the dilation with the rule (6/5x, 6/5y), the corresponding point P'(x', y') will be:
P' = (6/5x, 6/5y)
The distance between point P and the origin is given by:
d(P) = √(x² + y²)
The distance between point P' and the origin is:
d(P') = √((6/5x)² + (6/5y)²)
= 6/5 * √(x² + y²)
Since the dilation multiplies each coordinate by a factor of 6/5, the distance between any point and the origin is multiplied by a factor of 6/5.
Therefore, if 6/5 < 1, then the distances between corresponding points are reduced, and the dilation is a reduction. If 6/5 > 1, then the distances are increased, and the dilation is an enlargement.
In this case, we have:
6/5 > 1
Therefore, the dilation is an enlargement, and Tashi is correct.

The speed of the train, which started, from point N was 5 mph faster than the speed of the other train. In two hours after the departure the distance between the trains was 30 mi. What is the speed of each train?
Answer:
Using the quadratic formula, we find that:
x = 0.555 or x = 89.445
We can ignore the first solution since it doesn't make sense for the speed of a train. Therefore, the speed of the slower train is approximately 89.445 mph, and the speed of the faster train is approximately 94.445 mph.

Therefore , the solution of the given problem of triangle comes out to be angle x has a magnitude of 101°.
What is a triangle?A triangle is a polygon since it possesses two or so additional components beyond that. It is plainly rectangular in form. A and B are the only two of either a triangle's three edges that can distinguish it from a typical triangle. When bounds are still not precisely collinear, Euclidean geometry yields a single region rather than a cube. Three edges and three angles are what make a triangle.
Here,
Because a triangle's angles sum up to 180 degrees, we can determine the size of angle x by deducting the other two angles from 180 degrees:
=> x = 180° - 35° - 44°
=> x = 101°
As a result, angle x has a magnitude of 101°.

The zeroes of the polynomial f(x) = x⁴ - 2x³ - 6x² + 22x - 15 are x = 1, x = 3, x = -3
Describe Polynomial?Polynomials can be classified by degree, which is the highest power of the variable in the polynomial. For example, the polynomial f(x) = 3x^4 - 2x^3 + x^2 - 5x + 2 is a fourth-degree polynomial, as the highest power of x is 4.
Polynomials can be added, subtracted, multiplied, and divided using a variety of techniques, including factoring, synthetic division, and long division. They can also be evaluated at specific values of the variable, which can be useful in solving problems or analyzing data.
We can find the zeroes of the polynomial function f(x) = x⁴ - 2x³ - 6x² + 22x - 15 by factoring it or by using numerical methods such as the Newton-Raphson method or the bisection method. Here, we will use the factoring method.
First, we can observe that x = 1 is a zero of the polynomial, since f(1) = 1 - 2 - 6 + 22 - 15 = 0. Therefore, we can factor out (x - 1) from the polynomial:
f(x) = x⁴ - 2x³ - 6x² + 22x - 15
= (x - 1)(x³ - x² - 7x + 15)
Therefore, we have:
x³ - x² - 7x + 15 = (x - 1)(x² - 9)
= (x - 1)(x - 3)(x + 3)
Therefore, the zeroes of the polynomial f(x) = x⁴ - 2x³ - 6x² + 22x - 15 are:

A 3rd grade math test included this rather tough challenge. Can you solve it? If 5*3=4 2*8=2 and 6*3=3 find the value of 1*7=?
Without a clear pattern or rule from the given examples, it is difficult to determine the value of 1*7 in this problem.
This problem appears to involve some sort of pattern or rule that relates the multiplication of two numbers to a resulting value. Let's examine the given examples to try to identify the pattern:
5*3=4: The product of 5 and 3 is 15, but the answer is 4. This means that some sort of operation was performed on 15 to produce 4. One possibility is that the digits of 15 were added together: 1 + 5 = 6, and then the result was subtracted from 10: 10 - 6 = 4. So, this pattern involves adding the digits of the product and subtracting the result from 10.
2*8=2: The product of 2 and 8 is 16, but the answer is 2. Again, we need to perform an operation on 16 to get 2. One possibility is to divide 16 by the sum of the digits: 1 + 6 = 7, so 16 / 7 = 2.28 (rounded to 2 decimal places). However, this pattern doesn't quite fit the given examples perfectly, so there may be other rules or variations involved.
6*3=3: The product of 6 and 3 is 18, but the answer is 3. Applying the same approach as before, we could try dividing 18 by the product of the digits: 6 * 3 = 18, so 18 / 18 = 1. However, this pattern doesn't match the previous examples either.

If in △ABC, A=27degree, a=37 and c=28, then the statements best describes the triangle is (B) △ABC is obtuse.
We can use the Law of Cosines to determine the length of side b:
b^2 = a^2 + c^2 - 2ac cos(A)
b^2 = 37^2 + 28^2 - 2(37)(28) cos(27°)
b ≈ 27.88
Now we can use the Law of Sines to determine the measure of angle B:
sin(B)/b = sin(A)/a
sin(B) = (b/a)sin(A)
sin(B) = (27.88/37)sin(27°)
B ≈ 46.18°
Finally, we can find the measure of angle C using the fact that the angles in a triangle sum to 180°:
C = 180° - A - B
C ≈ 106.82°
Since angle C is greater than 90°, we know that △ABC is obtuse triangle. Therefore, the best statement that describes the triangle is (B) △ABC is obtuse.

Answer:

Step-by-step explanation:
The formula for accrued amount on a loan(value of loan) is given by the formula if compounded yearly is
[tex]A = P\left(1 + r)^t[/tex]
where
P = original loan amount
r = interest rate in decimal
t = number of years
We are given that the original loan amount
P = £5500
After 1 year the accrued amount
[tex]A = 5500(1 + r)^1[/tex]
and we know that after 1 year, the value of the loan is £5698
Therefore
5698 = 5500(1 + r)
1+ r = 5698/5500 = 1.036
r= 1.036 - 1 = 0.036
In percentage terms 0.036 = 0.036 x 100 = 3.6%

What is probability?
A probability is a number that expresses the possibility or likelihood that a specific event will take place. Probabilities can be stated as proportions with a range of 0 to 1, or as percentages with a range of 0% to 100%.
We will get
p = 8/20 = 2/5 = 0.4
In percentage form this is:
p = 100%*0.4 = 40%
While the theoretical probability depends on the quotient between the number of red sections and the total number of sections.
There are 3 red sections and 8 sections in total, so here the probability is:
p = 100%*3/8 = 37.5%
So the correct option is C.

1/(sec - tan) - 1/cos = 1/cos - 1(sec + tan)
=> 1/(sec - tan) + 1(sec + tan) = 1/cos + 1/cos
Left side
(sec + tan)/[(sec - tan)(sec + tan)] + (sec - tan)/[(sec - tan)(sec + tan)]
= [sec + tan + sec - tan]/[(sec - tan)(sec + tan)]
= [2sec]/[(sec - tan)(sec + tan)]
since (a+b)(a-b) = a^2 - b^2
=> 2sec/(sec^2 - tan^2)
let's work on the denominator (sec^2 - tan^2)
we know sec = 1/cos and tan = sin/cos
=> (1/cos)^2 - (sin/cos)^2
=> 1/cos^2 - sin^2/cos^2
=> (1 - sin^2)/cos^2 = cos^2/cos^2 = 1
so 2sec/(sec^2 - tan^2) => 2sec/1
=> 2sec
since sec = 1/cos => 2sec = 2(1/cos) = 2/cos
Right side
1/cos + 1/cos = 2/cos

In order to complete a relative frequency table to show the distribution of data with respect to color in a parking lot with 55 vehicles, you must first understand the concept of frequency. Frequency is the number of times a particular element appears in a given set of data. In this case, the elements are the colors of the vehicles in the parking lot.
To begin, you must count the number of vehicles of each color in the parking lot and record the number in the appropriate column. Then you must calculate the relative frequency for each color. Relative frequency is calculated by dividing the frequency of a color by the total number of vehicles. To find the total number of vehicles in the parking lot, simply add up the number of vehicles of each color. Once you have the relative frequency for each color, you can complete the relative frequency table.The first two numbers in each row of the relative frequency table must add up to 100%. This is because they represent the percentages of the total number of vehicles in the parking lot. If the percentages do not add up to 100%, then the table would not accurately reflect the distribution of data with respect to color. In conclusion, to complete a relative frequency table to show the distribution of data with respect to color in a parking lot with 55 vehicles, you must understand the concept of frequency, count the number of vehicles of each color, calculate the relative frequency for each color, and ensure that the first two numbers in each row add up to 100%.

c. What is the probability that the patient will test positive for Covid-19?
d. What is the probability that the patient will test negative?
e. What is the probability that the patient does not have Covid-19 if he or she tests positive for it?
f. What is the probability that the patient has Covid-19 if he or she tests negative?
Therefore , the solution of the given problem of probability comes out to be there is a 0.73 percent chance that a patient will test clear for Covid-19.
What is probability exactly?The primary goal of the designs inside a practice known as criteria is the evaluation of the likelihood that a claim is accurate or that a specific event will occur. Any number between 0 and 1 can be used to represent chance, with 1 usually representing a range level of certainty and 0 typically representing possibility. A probability diagram shows the chance that a specific event will occur. Just the digits 0% and approximately 100% make up the decimal 1, 0, and 0.
Here,
a. P(Covid-19 positive) of 25,000/100,000 equals 0.25
b. P(Covid-19 negative) = 75,000/100,000 = 0.75
c. P(positive test) equals P(positive test | Covid-19 positive) * P(Covid-19 positive) + P(positive test | Covid-19 negative) * P(positive test | Covid-19 positive) (Covid-19 negative)
P (positive test | Covid-19 positive) = 0.82, while P (positive test | Covid-19 negative) = 0.18
When we enter the numbers, we obtain:
P(positive test) is equal to 0.82 * 0.25 + 0.18 * 0.75 = 0.31.
As a result, there is a 0.31 percent chance that a patient will test positive for Covid-19.
d. P(negative test) = P(negative test | Covid-19 negative) * P(Covid-19 negative) + P(negative test | Covid-19 positive) * P(negative test | Covid-19 negative) * P (Covid-19 negative)
Since the test is correct 82% of the time, we know that if a patient has Covid-19, the test will be negative 18% of the time, so:
P(positive test, negative Covid-19) = 0.18 P(negative test, positive Covid-19) = 0.95
When we enter the numbers, we obtain:
P(negative test) = 0.18*0.025+0.95*0.075=0.73
Therefore, there is a 0.73 percent chance that a patient will test clear for Covid-19.

Solve the following equations by using the properties of logarithms
Log 2x = 5

Log x= log (2/x) +1
The value of the following equations by using the properties of logarithms: 1.x = 50000 2. x = (1 ± √5) / 4 3. x= 2√5.
What is equation?In mathematics, an equation is a statement that asserts the equality of two expressions, usually separated by an equal sign (=). An equation typically consists of one or more variables, coefficients, constants, and mathematical operations, such as addition, subtraction, multiplication, division, exponentiation, and roots. The purpose of an equation is to find the values of the variables that satisfy the equation. These values are called solutions or roots of the equation. Equations are used in many branches of mathematics, including algebra, calculus, geometry, and statistics, to model and solve various problems and phenomena in the natural and social sciences, engineering, and finance.
Here,
1. Log 2x = 5
We can rewrite this equation using the property that log_a(b) = c is equivalent to b = aˣ:
2x = 10⁵
Simplifying the right-hand side, we get:
2x = 100000
Dividing both sides by 2, we get:
x = 50000
Therefore, the solution is x = 50000.
2. Lnx - In(2x+1) = 2
Using the fact that ln a - ln b = ln(a/b), we can simplify the left-hand side of the equation:
ln(x/(2x+1)) = 2
Next, we can rewrite the equation in exponential form:
e² = x/(2x+1)
Multiplying both sides by 2x+1, we get:
e²(2x+1) = x
Expanding and simplifying the left-hand side, we get a quadratic equation:
4xe² + 2e² - x = 0
Solving for x using the quadratic formula, we get:
x = (-2e² ± √((2e²)² - 4(4e²)(-1))) / (2(4e²))
Simplifying, we get:
x = (-e² ± √(e⁴ + 4e₂)) / (4e²)
x = (-e² ± e²√5) / (4e²)
x = (1 ± √5) / 4
Therefore, the solutions are x = (1 + √5) / 4 and x = (1 - √5) / 4.
3. Log x = log (2/x) + 1
Using the fact that log_a(b) = log_a(c) is equivalent to b = c, we can simplify the equation:
x = 2/x * 10
Multiplying both sides by x, we get:
x² = 20
Taking the square root of both sides, we get:
x = ±√(20)
Since x cannot be negative (because log of a negative number is undefined), the only solution is:
x = √(20) = 2√5

educational stationary Nishaben and collected GST of Rs.2100. Find the GST CGST and
SGST to be paid
Answer: Therefore, Hamid needs to pay Rs. 1050 as both CGST and SGST.
Step-by-step explanation:
Assuming the GST rate is the same for both the purchase and the sale, we can calculate the GST rate as follows:
GST rate = GST paid / Cost of stationary purchased
= 1800 / Cost of stationary purchased
Since we don't have the cost of stationary purchased, we can't calculate the GST rate or the CGST and SGST amounts directly. However, we know that the GST collected from Nishaben was Rs. 2100, which is equal to the GST paid plus the profit earned on the sale. We can express this mathematically as follows:
GST collected = GST paid + Profit
Profit = GST collected - GST paid
= 2100 - 1800
= Rs. 300
Since the profit earned is Rs. 300, we can find the cost of the stationary purchased by subtracting the profit from the amount collected from Nishaben:
Cost of stationary purchased = GST collected - Profit
= 2100 - 300
= Rs. 1800
Now that we know the cost of the stationary purchased, we can calculate the GST rate as follows:
GST rate = GST paid / Cost of stationary purchased
= 1800 / 1800
= 1
Since the GST rate is 1 (or 100%), we can divide the total GST collected equally between CGST and SGST:
CGST = SGST = GST collected / 2
= 2100 / 2
= Rs. 1050
Therefore, Hamid needs to pay Rs. 1050 as both CGST and SGST.

The Pacific Ocean is roughly 100 times bigger than the Gulf of Mexico.
What is Ocean?Ocean is the largest and most prominent feature of the Earth's surface. It covers more than 70% of the planet and contains 97% of its water. Oceans are vital to life on Earth, providing food and resources, regulating the climate, and supporting a vast array of marine life. They are home to a variety of habitats including coral reefs, deep sea trenches, and shallow coastal estuaries.
The Pacific Ocean covers an area of roughly 63.8 million square miles (165.2 million square kilometers), while the Gulf of Mexico covers an area of only 615,000 square miles (1.6 million square kilometers). This means that the Pacific Ocean is roughly 6 x 105 (or 600,000) times bigger than the Gulf of Mexico.

What is the probability that Z is less than 1.56? The probability that Z is less than 1.56 is 0.9406. (Round to four decimal places as needed.) b. What is the probability that Z is greater than 1.81 ? The probability that Z is greater than 1.81 is 0.0351. (Round to four decimal places as needed.) c. What is the probability that Z is between 1.56 and 1.81 ? The probability that Z is between 1.56 and 1.81 is (Round to four decimal places as needed.) d. What is the probability that Z is less than 1.56 or greater than 1.81 ? The probability that Z is less than 1.56 or greater than 1.81 is (Round to four decimal places as needed.)
From the given data, the probability of Z less than 1.56, greater than 1.56, between 1.56 and 1.81 and less than 1.56 or greater than 1.81 is 0.9406, 0.0359, 0.0235 and 0.9765 respectively.
a. From the cumulative standardized normal distribution table, we can look up the value 1.56 in the left column and find the corresponding value of 0.9406 in the intersecting row. Therefore, the probability that Z is less than 1.56 is 0.9406.
b. From the cumulative standardized normal distribution table, we can look up the value 1.81 in the left column and find the corresponding value of 0.9641 in the intersecting row. Since we want the probability that Z is greater than 1.81, we subtract this value from 1 to get 1 - 0.9641 = 0.0359 (rounded to four decimal places as needed). Therefore, the probability that Z is greater than 1.81 is 0.0359.
c. To find the probability that Z is between 1.56 and 1.81, we need to subtract the probability that Z is less than 1.56 from the probability that Z is less than 1.81. From the table, we know that the probability that Z is less than 1.56 is 0.9406 and the probability that Z is less than 1.81 is 0.9641. Therefore, the probability that Z is between 1.56 and 1.81 is 0.9641 - 0.9406 = 0.0235 (rounded to four decimal places as needed).
d. The probability that Z is less than 1.56 or greater than 1.81 is the sum of the probabilities that Z is less than 1.56 and Z is greater than 1.81, since these events are mutually exclusive. From parts (a) and (b), we know that the probability that Z is less than 1.56 is 0.9406 and the probability that Z is greater than 1.81 is 0.0359. Therefore, the probability that Z is less than 1.56 or greater than 1.81 is 0.9406 + 0.0359 = 0.9765 (rounded to four decimal places as needed).

If MNO IS NMO what statement best describes triangle MON?
If MNO is NMO, it means that the second and third vertices of the triangle have switched places, but the first vertex remains the same. Therefore, triangle MON is congruent to triangle NMO.
as they have the same side lengths and angles. Specifically, the sides MO, ON, and NM are congruent, and the angles at vertices M, O, and N are also congruent. We can represent this relationship between the two triangles using the symbol ≅, so we can say that triangle MON ≅ triangle NMO. The concept of congruent triangles is a fundamental principle in geometry. Two triangles are said to be congruent if their corresponding sides and angles are equal. When two triangles are congruent, we can say that they have the same size and shape, but they may be oriented differently in space. here are several ways to prove that two triangles are congruent, such as the side-angle-side (SAS), angle-side-angle (ASA), side-side-side (SSS), angle-angle-side (AAS), and hypotenuse-leg (HL) congruence criteria.
