Let x be a random variable distributed as normal(5,4). Find the probabilities of the following events: (i) p(x::; 6). (ii) p(x > 4 ). (iii) p( ix- 5 1 > 1
From the given information provided, the probability of P(X ≤ 6), P(X˃ 4) and P(|X- 5| ˃ 1) is 0.6915, 0.6915 and 0.3829 respectively.
(i) To find P(X ≤ 6), we need to standardize the value of 6 using the formula:
Z = (X - μ) / σ
where μ = 5 and σ = 2 (since the standard deviation is the square root of the variance, which is 4).
So, we have:
Z = (6 - 5) / 2
Z = 0.5
We can then look up the probability of Z ≤ 0.5 in a standard normal distribution table, or use a calculator to find:
P(X ≤ 6) = P(Z ≤ 0.5) = 0.6915
(ii) To find P(X > 4), we again need to standardize the value of 4:
Z = (4 - 5) / 2
Z = -0.5
Then, we can use the fact that the total area under a normal distribution curve is 1 to find the probability of X being greater than 4:
P(X > 4) = 1 - P(X ≤ 4) = 1 - P(Z ≤ -0.5)
Using a standard normal distribution table:
P(X > 4) = 0.6915
(iii) To find P(|X - 5| > 1), we first need to transform this inequality into a standard normal distribution by standardizing both sides:
|X - 5| > 1
implies:
X - 5 > 1 or
X - 5 < -1
which gives:
X > 6 or X < 4
We can then standardize each inequality separately. For X > 6, we have:
Z = (6 - 5) / 2
Z = 0.5
and for X < 4, we have:
Z = (4 - 5) / 2 = -0.5
Then, using the fact that the total area under a normal distribution curve is 1, we can find the probability of both events occurring:
P(|X - 5| > 1) = P(X > 6 or X < 4) = P(Z > 0.5 or Z < -0.5)
Since the standard normal distribution is symmetric around 0:
P(Z > 0.5 or Z < -0.5) = 2 × P(Z < -0.5)
Using a standard normal distribution table:
P(|X - 5| > 1) = 0.3829

Adding 16/ to both sides:
=> h = (16/π) x 1.0625
=> h = 16.8125/π
=> h ≈ 5.3529
=> H = 5.353 inches is the result of rounding to the closest thousandth.

About 16 people among the 1,000 insured people can file a claim for a surgical procedure.
define profitProfit is the financial gain earned by a business or an individual after deducting all the expenses and costs associated with generating that revenue. It represents the difference between the total revenue earned and the total expenses incurred.
The total amount collected in premiums over 3 years for Bracken is:
$100 x 1,000 x 3 = $300,000
Assuming x people among the 1,000 insured people file a claim for a surgical procedure, the total amount paid out in claims by Bracken would be:
$25,000 x x = $25,000x
The total deductible paid by the claimants would be:
$3,500 x x = $3,500x
So, the total amount paid out by Bracken would be:
$25,000x + $3,500x = $28,500x
For Bracken to break even, the total amount collected in premiums should be equal to the total amount paid out in claims plus the deductible for 3 years.
$300,000 = $28,500x + $3,500(1,000 - x)
Simplifying and solving for x, we get:
x = 16

The figure similar to figure E after dilation is figure F.
What are transformations?The transformation, or f: X X, is the name given to a function, f, that maps to itself. After the transformation, the pre-image X becomes the picture X. Any operation, or a combination of operations, such as translation, rotation, reflection, and dilation, can be used in this transformation. A function can be moved in one way or another using translation, rotation, reflection, and dilation. A function can also be scaled using rotation around a point. Two-dimensional mathematical figures move about a coordinate plane according to transformations.
We know that when a figure is dilated the ratio of their sides are same, that is they are proportional.
From the graph we observe that the line passes through the point F and E. Thus, the sides of the figure are proportional or in linear relation with each other.
Hence, the figure similar to figure E after dilation is figure F.

4. A stone nudged off the Royal Gorge Bridge near Cañon City, Colorado, falls 1053 feet before hitting water. Because its speed increases as it falls, the distance it travels each second increases. During the first second, it drops 16 feet. During the next second, it drops an additional 48 feet. During the third second, it drops another 80 feet. The distances traveled each second form an arithmetic sequence:
16, 48, 80, ...
Part I: How far does the stone fall during the 5th second? Find and use the explicit formula.
a. What is the first term of the sequence? _____
b. What is d, the common difference? _____
c. Write the explicit formula in function notation. Use f(n) = f(1) + (n – 1)d, where f(1) represents the first term. _______________
d. Use the explicit formula to find the distance the stone travels in the 5th second.
a. The first term of the sequence is 16.
b. the common difference is d = 32
c. the explicit formula is f(n) = 16 + (n - 1)32
d. the stone falls a distance of 144 feet during the 5th second.
How to find the first term in the sequencea. The first term of the arithmetic sequence is given to be 16.
b. To find the common difference, we can subtract the second term from the first term, then the third term from the second term:
48 - 16 = 32
80 - 48 = 32
Therefore, the common difference is d = 32.
c. Using f(n) = f(1) + (n - 1)d,
where
f(1) = 16 and d = 32,
we can write the explicit formula for the distance traveled during the nth second as:
f(n) = 16 + (n - 1)32
d. To find the distance traveled during the 5th second, we plug in n = 5 into the explicit formula:
f(5) = 16 + (5 - 1)32
f(5) = 16 + 4*32
f(5) = 16 + 128

The value of tan(A - B) will be 15/8.
As mentioned, cscA= -17/15 and A is in Quadrant III and sinB=12/13 where B is in Quadrant I To find tan(A - B), we need to have the values of sin (A - B) and cos (A - B).We know that, sin(A - B) = sinAcosB - cosAsinB and cos(A - B) = cosAcosB + sinAsinB.Since we have the values of sinA, cosA, and sinB, let's find the values of cosA and cosB.First, let's find cosA. We know that cscA = 1/sinA. Therefore, sinA = -15/17.Since A is in Quadrant III, sinA < 0, cosA < 0, and tanA > 0.
By using the Pythagorean identity sin^2A + cos^2A = 1, we get cosA = -8/17.Next, let's find cosB. We know that sin^2B + cos^2B = 1.
Therefore, cosB = sqrt(1 - sin^2B) = 5/13.
Since B is in Quadrant I, sinB > 0, cosB > 0, and tanB > 0.
Now, we have sinA, cosA, sinB, and cosB.
Using the values of sinA, cosA, sinB, and cosB, let's find sin(A - B) and cos(A - B).
sin(A - B) = sinAcosB - cosAsinB= (-15/17)(12/13) - (-8/17)(5/13)= -180/221
cos(A - B) = cosAcosB + sinAsinB= (-8/17)(12/13) + (-15/17)(5/13)= -96/221
Finally, tan(A - B) = sin(A - B) / cos(A - B)= (-180/221) / (-96/221)= 15/8. Therefore, tan(A - B) = 15/8.

Gender Selection The Genetics and IVF Institute conducted a clinical trial of the YSORT method designed to increase the probability of conceiving a boy. As of this writing, 291 babies were born to parents using the YSORT method, and 239 of them were boys. 291/239= a. What is the best point estimate of the population proportion of boys born to parents using the YSORT method? b. Use the sample data to construct a 99% confidence interval estimate of the proportion of boys born to parents using the YSORT method. c. Based on the results, does the YSORT method appear to be effective? Why or why not? Theoretical probability is u. population proportion is o. 90% confidence interval
the 99% confidence interval estimate for the proportion of boys born to parents using the YSORT method is: (0.7584, 0.8820)
what is an algebraic expression?
An algebraic expression is a mathematical phrase consisting of numbers, variables, and mathematical operations such as addition, subtraction, multiplication, and division.
a. The point estimate of the population proportion of boys born to parents using the YSORT method can be calculated as the ratio of the number of boys to the total number of babies:
239/291 ≈ 0.8202
Therefore, the best point estimate of the population proportion of boys born to parents using the YSORT method is approximately 0.8202.
b. To construct a 99% confidence interval estimate of the proportion of boys born to parents using the YSORT method, we can use the following formula:
p ± z*sqrt(p(1-p)/n)
where p is the point estimate of the population proportion, z* is the critical value from the standard normal distribution for the desired confidence level (99% in this case), and n is the sample size.
Using the values from part (a), we have:
p = 0.8202
n = 291
z* = 2.576 (from the standard normal distribution table for a 99% confidence level)
Plugging in these values, we get:
0.8202 ± 2.576sqrt(0.8202(1-0.8202)/291)
Simplifying, we get:
0.8202 ± 0.0618
c. Based on the results, the YSORT method appears to be effective in increasing the probability of conceiving a boy. The point estimate of 0.8202 is significantly higher than the theoretical probability of 0.5 for a randomly selected baby to be a boy.
Therefore, the 99% confidence interval estimate for the proportion of boys born to parents using the YSORT method is: (0.7584, 0.8820)

A rock is dropped from a height of 100 feet. Calculate the time between when the rock was dropped and when it landed. If we choose "down" as positive and ignore air friction, the function is h(t)=16t^2-100
T= 2. 5 seconds
t = 10 seconds
t = 12. 5 seconds
t = 6. 25 seconds
When "down" is positive and air friction is disregarded, the time it takes for the rock to touch the ground may be calculated using the formula [tex]h(t)=16t2-100[/tex] to be roughly 6.25 seconds.
the formula[tex]h(t)=16t2 - 100[/tex]when a rock is dropped from a height of 100 feet, and assuming that "down" is positive and air friction is neglected, represents the height of the rock at time t in seconds.
As the rock will land at the value of t when h(t) = 0, we must determine that value in order to determine how long it takes for the rock to land.
When we set h(t) to 0 we obtain 0 = 16t2 - 100.
[tex]16t^2 = 100 \st^2 = 100/16 \st^2 = 6.25 \st = ±√6.25[/tex]

A poster storage tube in the shape of a cylinder has a diameter of inches and a volume ofcubic inches.
What is the height of the poster storage tube in inches?
ANSWER IS ON VERY BOTTOM.
The formula for the volume of a cylinder is V = πr^2h, where r is the radius and h is the height. We are given the diameter of the cylinder, which is 4 inches, so the radius is half of that, or 2 inches. We are also given the volume of the cylinder, which is V = cubic inches.
Substituting these values into the formula, we get:
cubic inches = π(2 inches)^2h
Simplifying, we have:
cubic inches = 4πh
To solve for h, we can divide both sides by 4π:
h = cubic inches / 4π
Using a calculator to evaluate this expression, we get:
h = 5.027 inches (rounded to three decimal places)
Therefore, the height of the poster storage tube is approximately 5.027 inches.
The height of the poster storage tube in inches is 40 inches.
What is Volume?Volume of a three dimensional shape is the space occupied by the shape.
Given that,
A poster storage tube in the shape of a cylinder.
Volume = 122.5π inches³
Diameter = 3.5 inches
Radius = Diameter / 2 = 1.75 inches
Volume of the cylinder = π r² h
where r is the radius of the base and h is the height of the cylinder.
Substituting,
π (1.75)² h = 122.5π
(1.75)² h = 122.5
h = 122.5 / (1.75)²
h = 40 inches

Multiplicative Rate of Change = (Change in Output)/(Change in Input)
For example, if a function f(x) has an input of 3 and an output of 9, then the multiplicative rate of change of the function would be 2. This can be calculated by taking the difference between the output and the input, which is 9 - 3 = 6, and dividing it by the difference between the input and the output, which is 3 - 0 = 3. Thus, the multiplicative rate of change of the function is 6/3 = 2.

The side opposite to angle B is AC. The side adjacent to angle B is BC. The hypotenuse is segment AB.
What is adjacent side and hypotenuse?A pair of sides are referred to as neighboring if they have a shared angle. The term "hypotenuse" refers to a right-angled triangle's longest side as compared to the base and perpendicular lengths. The right angle, the largest angle of the three angles in a right triangle, lies opposite the hypotenuse side. In essence, only the right triangle possesses the hypotenuse feature, not any other triangles.
From the figure we observe that the side opposite to angle B is AC.
The angle adjacent to angle B is BC.
The hypotenuse is segment AB.

A rectangle has side lengths of x cm and (x+y) cm, where x and y are both positive. The rectangle has an area of 57 cm squared and a perimeter of 44 cm. work out the values of x and y
The value of x and y for the rectangle has side lengths of x cm and (x+y) cm are found as : x = 3 and y = 16.
Explain about the area of rectangle?The total of a rectangle's four sides is its perimeter. The equation Perimeter of Rectangle = 2 (Length + Width) is used to calculate it. The region contained within the boundaries of a rectangle is its area, which may be determined using the formula area of rectangle = length width.Dimensions are:
Length L = x cmWidth w = (x + y) cmArea = 57 cm squared perimeter = 44 cm.Then,
Area = l*w
57 = x(x + y) ....eq 1
Perimeter = 2(l + w)
44 = 2(x + x + y)
22 = 2x + y
y = 22 - 2x ...put in eq 1
57 = x(x + y)
57 = x(x + 22 - 2x)
57 = x(22 - x)
Simplifying:
57 = 22x - x²
Or.
x² - 22x + 57
Factorizing using quadratic formula:
x = 19 ans x = 3
For x = 19
y = 22 - 2*19
y = 22 - 38 (negative value not possible)
So, x = 3
y = 22 - 2*3
y = 22 - 6
y = 16
Thus, the value of x and y for the rectangle has side lengths of x cm and (x+y) cm are found as : x = 3 and y = 16.

4.) You decide to paint your room, too.
Your room has 300 square feet of wall space to paint. Sam says it took her 10 minutes to paint 25 square feet. At this rate, how many hours would it take Sam to paint your room?
Answer: 2 hours
Step-by-step explanation: (10 min) / (25 square feet) = (X minutes) / (300 square feet)
Cross-multiply to solve, as we always do with proportions:
10 * 300 = 25 * x
3000 = 25X
3000/25 = 25X /25

if there are 6 consecutive numbers and 10 is the smallest one, what is their sum?
Hence, 75 is the result of adding the six consecutive integers starting at 10.
What are consecutive numbers?Numbers that follow one another sequentially are known as consecutive numbers. Every time there are two numbers, there is a 1 difference.
We can find the sum of these numbers by adding them up if there are six consecutive numbers and 10 is the smallest one.
The six numbers in order are x, x+1, x+2, x+3, x+4, and x+5. We are aware that x equals 10 because 10 is the smallest number.
The six numbers are therefore 10, 11, 12, 13, 14, and 15.
We simply put them together to determine their sum:
10 + 11 + 12 + 13 + 14 + 15 = 75

An equation to find the length of the base of the triangle is 86 = ?
The length of the base of the triangle is ? inches
Answer the word problem UvU
A triangular bandana has an area of 86 square inches. The height of the triangle is 5 3/8 inches. An equation to find the length of the base of the triangle is 86 = 1/2 * b * 43/8
The length of the triangle's base is 32 inches.
We know that the formula for calculating the area of a triangle is:
1/2 * base * height = area
We also know that the triangle's height is 5 3/8 inches, which may be expressed as a mixed number:
Height = 5 + 3/8 inch = 43/8 inch
Let b be the base of the triangle.
Substituting these numbers into the area formula yields:
86 = 1/2 * b * 43/8
To find b, multiply both sides of the equation by 2/43:
86 * 2/43 = 2/43 * 1/2 * b * 43/8
4 = b/8
b = 32
As a result, the length of the triangle's base is 32 inches.

Yes, the Median of a triangle is also an altitude and the triangle is isosceles.
What is the altitude of a triangle?The altitude of a triangle is the perpendicular line segment drawn from the vertex of the triangle to the side opposite to it
A median of a triangle is a line segment joining a vertex to the midpoint of the opposite side, thus bisecting that side.
In an isosceles triangle, two sides that are equal meet at a vertex that lies directly above the base midpoint. Because of this altitude from the vertex bisect the base at midpoint median to the base from the vertex.
Therefore, Median of a triangle is also an altitude and the triangle and it is isosceles.
