Answer:
1.5 < x < 34.7
Step-by-step explanation:
You want a compound inequality describing possible lengths (x) for the third side of a triangle with sides 18.1 and 16.6.
Triangle inequalityThe shortest side cannot be any shorter than the difference of the two known sides:
18.1 -16.6 = 1.5
The longest side cannot be any longer than the sum of the two known sides:
18.1 +16.6 = 34.7
The possible lengths of the third side are given by ...
1.5 < x < 34.7
__
Additional comment
If the third side is exactly equal to the sum or the difference, then the "triangle" looks like a line segment. It has zero area. That possibility is usually disallowed. If you want to allow it, then change < to ≤ in the inequality.
aldo's coffee shop makes a blend that is a mixture of two types of coffee. type a coffee costs $4.10 aldo per pound, and type b coffee costs $5.45 per pound. this month's blend used twice as many pounds of type b coffee as type a, for a total cost of $465. how many pounds of type a coffee were used?
The amount of type A used is A=31 lbs.
Assign variables for unknowns.
Let A be the number of pounds of Type A coffee.
Let B be the number of pounds of Type B coffee.
If one pound of Type A costs $4.10 then A pound costs 4.10A
If one pound of Type B costs $5.45 then B pounds cost 5.45B
At this point, you have two equations with A and B as variables. You can use the substitution or elimination method to solve for A.
Equations:
B = 2A----(1)
4.10A + 5.45B = 465.00
4.10A + 5.45(2A) = 465.0
4.10A + 10.9A = 465.00
15A = 465.00
A = 31 lbs (amt. of type A coffee used)
To know the amount of type B coffee used just plug the A value in equation(1) we get:
B=2(31)
B=62.

What is the area of the triangle?
16 square units
32 square units
8 square units
4 square units
Answer:
8 square units
Step-by-step explanation:
For a triangle,
area = base × height / 2
We need to identify a base and a height for this triangle, and then use them in the area formula above.
Use BC as the base.
A height of a triangle is usually inside the triangle, but not always.
The height of a triangle is a segment that is perpendicular to the a side, or the line containing a side, and intersects the opposite vertex.
In this case, for base BC, the height is a segment from point (-2, 2) to point A. The length of the height is 4.
area = 4 × 4 / 2
area = 8 square units

if the image of point (x,5) is (-6, y) when it is translated by the vector t(6 -2) Find the vaue of x and y
If the image of point (x,5) is (-6, y) when it is translated by the vector t(6 -2), then the values of x = -12 and y = 3.
What is mean by translated by vector?Vector translation is a mathematical concept that describes how an object is moved in space. It involves the use of a vector, which is a quantity that has both magnitude and direction. A vector can represent a displacement, a velocity, an acceleration, or any other physical quantity that has both magnitude and direction.
When an object is translated by a vector, it moves a certain distance in a specific direction. This is usually done by adding the vector to the current position of the object. The magnitude of the vector determines the distance of the translation, while the direction of the vector determines the direction of the translation.
Additionally, the vector can be used to rotate the object. This is done by multiplying the vector by the object’s rotation matrix. The result is the object's new orientation in space, which can be used to orient the object in a different direction.
Vector translation is used in a variety of applications, including computer graphics, robotics, and navigation systems. It i also used in mathematics and physics to represent physical phenomena, such as forces, velocities, or accelerations.
Let the point P(x,5) be translated by the vector t(6,-2).
The image of point P is (x',y') = (x+6,5-2) = (-6,y)
Therefore, x+6 = -6
=> x = -6-6 = -12
Similarly, 5-2 = y
=> y = 5-2 = 3
So the value of x is -12 and y is 3.

Answer: To find r'(1), we need to use the chain rule of differentiation, which states that:
r'(x) = f'(g(h(x))) * g'(h(x)) * h'(x)
In this case, we know that:
h(1) = 2, g(2) = 4, h'(1) = 4, g'(2) = 4, and f '(4) = 7
Therefore:
r'(1) = f'(g(h(1))) * g'(h(1)) * h'(1) = f'(g(2)) * g'(2) * h'(1) = 7 * 4 * 4 = 112
So, the derivative of r(x) with respect to x at x = 1 is 112

What is square and square roots?The square root of a number is the part of the number that, when multiplied by itself, produces the original number. Squares and square roots are examples of special exponents. The portion of a number that yields the original number when multiplied by itself is known as the square root of the number.
Examples of special exponents include squares and square roots. Think about the number 9. Nine is the result of multiplying 3 by itself. This can be expressed as either or 3*3. We refer to this as a square since it has a 2 exponent. When the exponent is now 1/2, the integer's square root is being discussed.

An automatic filling machine is used to file 1-liter bottles of cola. The machine's output is approximately normal with a mean of 1. 0 liter and a standard deviation of 0. 01 liter. Output is monitored using means of sample of 25 observations. What is the z-value we should use if the control limits will include roughly 97% of the sample means
The UCL and LCL are 1.00434 and 0.99566. The process is not in control and the z-value is 2.17.
We already know that the mean, x = 1.0, and the standard deviation of the process, σ = 0.01.
We already know that according to the central limit theorem, the standard deviation of sample means is equal to the standard deviation of the population divided by the square root of the sample size.
So, it is equal to = 0.01 / √25 ⇒ 0.002
For a sample size of 25. The z value, or the z-score, is about 2.17 for a confidence level of 97 percent.
So, UCL = 1.0 + 2.17 * 0.002 = 1.00434
LCL = 1.0 - 2.17 * 0.002 = 0.99566
Lastly, the process is not in control because the sample means 1.005 and 0.995 are outside the control range.

In math Bernoulli's theorem is states that that random experiment with exactly two possible outcomes, "success" and "failure" in which the probability of success is the same every time the experiment is conducted.
In order to calculate p we must sum the possible permutations of getting 0 success of 10 trials, 1 success of 10 trials, and 2 successes of 10 trials, and divide this sum by the total possible subsets from 10 elements, then it can be written as,
=> P = (10 1) (10 2) (10 1) / 2¹⁰
When we simplify this one, then we get,
=> P = 56/1024
=> P = 0.0547
When we apply the value on Bernoulli's theorem, then we get,

(1+12x)^1/2
giving each term in simplest form.
(b) Explain how you could use x=1/36 in the expansion to find an approximation for √12
There is no need to carry out the calculation.
a) The binomial expansion of (1+12x)^1/2 is given by:
(1+12x)^1/2 = 1^1/2 + (1/2)(1^-1/2)(12x) + (1/2)(1^-1/2)(-1/2)*(12x)^2 + ...
Binomial expression: what is it?
A polynomial with only terms is a binomial. An illustration of a binomial is x + 2, where x and 2 are two distinct terms. Additionally, in this case, x has a coefficient of 1, an exponent of 1, and a constant of 2. As a result, a binomial is a two-term algebraic expression that contains a constant, exponents, a variable, and a coefficient.
The first four terms, in ascending powers of x, are:
1, (1/2)(12x), (1/8)(12x)^2, (1/16)*(12x)^3
b) To use x=1/36 in the expansion, you would substitute x=1/36 into the expansion, and keep only the terms up to x^3 (the fourth term in the expansion). This will give an approximation of the value of (1+12x)^1/2 when x=1/36.
This will be an approximation of √12 because x=1/36 corresponds to 12x = 1 and the initial value of the expansion is 1 + 12x .
We can use this approximation to approximate square root of 12 and also for other square roots by using appropriate x values.

In a survey of 120 people who visited a lake, 20% went fishing. Of those who went fishing, 75% also went swimming. Of those who did not go fishing, 50% went swimming.
The two-way frequency table to display the data will be:
Fishing Not Fishing Total
Swimming 15 30 45
Not Swimming 5 45 50
Total 20 75 95
What is the frequency table about?20% of 120 people is 24 people, but since 20% of the people went fishing, we know that 24 people went fishing.
75% of 24 people who went fishing is 18 people.
50% of 96 people who did not go fishing is 48 people.
Total number of people who went swimming is 45 (15+30)
Total number of people who did not go swimming is 50 (5+45)
Total number of people in the survey is 95 (24+71)

Philip wants to run a total of 3 miles each day. Monday morning, he ran 1 7/8 miles. How many more miles does he still need to run?
On Monday, for completing the daily target Philip needs to travel 9/8 more miles.
As per the question,
As Philip wants to run a total of 3 miles each day.
As on Monday morning, he ran only 1(7/8) miles.
First, we will convert the given mixed fraction in form of improper fractions.
So, converting 1(7/8),
It will become equal to (8*1+7)/8 = 15/8
From above,
We can say, out of the 3 miles he only travel 15/8 miles on Monday.
So, for calculating the required distance we need to subtract the given value 15/8 from 3
Thus we will get it as:
3-15/8 = (24-15)/8 = 9/8 miles.

Conider the line .3x-6y=-8
Find the equation of the line that i parallel to thi line and pae through the point .4,2
Find the equation of the line that i perpendicular to thi line and pae through the point . (4,2)
The equation of the straight line perpendicular to the line 3x - 6y = - 8 is y-2x+6=0 and of line parallel to the line 3x - 6y = - 8 is y=0.
The general equation of a straight line is -
y=mx+c
where -
m is slope of line which tells the unit rate of change of y with respect to x.
c is the y - intercept i.e., the point where the graph cuts the y axis.
The equation of a straight line can be also written as -
Ax + By + C = 0
By = - Ax - C
[tex]y=\frac{-A}{B} x-\frac{C}{B}[/tex]
Given that: -
[tex]3x-6y=8\\\\6y=3x-8\\\\y=\frac{1}{2}x-\frac{4}{3}[/tex]
then,
[tex]m=\frac{1}{2}\\\\c=\frac{4}{3}[/tex]
For a parallel line,
[tex]m=\frac{1}{2}\\and,(4,2)[/tex]
[tex]y-y_{1}=m(x-x_{1})\\\\y-2=\frac{1}{2}(x-4)\\\\2y-4=x-4\\\\y=\frac{x}{2}[/tex]
The equation of parallel line is y=0.5x
For a perpendicular line
[tex]m=2\\\\y-2=2(x-4)\\\\y-2=2x-8\\y-2x=-6\\y-2x+6=0\\[/tex]
Therefore, the equation of the line perpendicular to the line 3x - 6y = - 8 is y -2x+6=0 and of line parallel to the line 3x - 6y = - 8 is y = 0.5x.

0.2040200100What is a frequency distribution?To make the information easier to understand, frequency distributions are visual displays that organise and present frequency counts. Absolute frequencies as well as relative frequencies, such as percentages or ratios, can be displayed in frequency distributions.
Given, a partial relative frequency distribution is given. class relative frequency a 0.22 b 0.18 c 0.40 d
Since all relative frequencies add up to be 1.
So,
0.22 + 0.18 + 0.40 + x = 1
x = 0.20
For b)
total sample size * relative frequency = frequency of a class
200*0.2 = 40
For c)
Frequency distribution is calculated as the frequency of a class = total sample size * relative freq.
A = 44
B = 36
C = 80
D = 40
TOTAL = 200
For d)
Percent frequency is calculated as Percent frequency of a class = 100 * relative freq.
A = 22
B = 18
C = 40
D = 20
TOTAL = 100
