Answer:
y = 18x + 60
Step-by-step explanation:
The slope intercept equation is:
y = mx + b
For this problem:
y will represent the total cost of the technician
m will represent cost per hour
x will represent number of hours
b will represent the initial cost
With this in mind, we can plug these into our equation
y = 18x + 60
Answer:
in slope intercept this would look like y = 18x + 60
What is the relationship between the angles of this equilateral triangle
Answer:
Is it A+B+C= 180 degrees
Step-by-step explanation:
all angles in a triangle add up to 180 degrees. It's also an equilateral triangle so each of its angles are 60 degrees
Answer:

all angles in a triangle add up to 180 degrees. It's also an equilateral triangle so each of its angles are 60 degrees
Does anybody know what measures a, b, and c would be?
Answer: A = 28 B = 47 C = 105 in degrees
Step-by-step explanation:
OKAY JUST A DISCLAIMER:
I did Geometry last year and the concepts are basically gone but I think I remember how to do this one
So I think one of the theorems stated that the inner angle is half of the outer arc.
So.. angle a would be 56/2 = 28
Angle b would be 94/2 = 47
Angle C is a vertical angle to the angle in the triangle, so it would be 180-47-28=105

The proportion of twins born in a town is p = 0.12. Suppose we randomly select 100 women from this town who give birth in the next year.
Which of the following is the correct calculation and interpretation of the standard deviation of the sampling distribution of p hat ?
Sigma Subscript p hat Baseline = 0.001 In SRSs of size 100, the sample proportion of women in this town giving birth to twins typically varies 0.001 from the true proportion, p = 0.12.
Sigma Subscript p hat Baseline = 0.032 In SRSs of size 100, the sample proportion of women in this town giving birth to twins typically varies 0.032 from the true proportion, p = 0.12.
Sigma Subscript p hat Baseline = 0.035 In SRSs of size 100, the sample proportion of women in this town giving birth to twins typically varies 0.035 from the true proportion, p = 0.12.
Sigma Subscript p hat Baseline = 0.106 In SRSs of size 100, the sample proportion of women in this town giving birth to twins typically varies 0.106 from the true proportion, p = 0.12.
Answer:
B. Sigma Subscript p hat Baseline = 0.032 In SRSs of size 100, the sample proportion of women in this town giving birth to twins typically varies 0.032 from the true proportion, p = 0.12.
Step-by-step explanation:
took the quiz
The correct calculation and interpretation of the standard deviation of the sampling distribution of p hat is the sample proportion of women in this town giving birth to twins typically varies 0.032 from the true proportion, 0.12.
What is random sample?Random sample is the way to choose a number or sample in such a manner that each of the sample of the group has an equal probability to be chosen.
The standard deviation of the sampling distribution of p hat is given as,
[tex]\sigma_{ \hat p}=\sqrt\dfrac{p(1-p)}{n}[/tex]
Here, p is the proportion and n is the number of sample.
The proportion of twins born in a town is p = 0.12. Now there is randomly select 100 women from this town who give birth in the next year.
[tex]\sigma_{ \hat p}=\sqrt{\dfrac{0.12(1-0.12)}{100}}\\\sigma_{ \hat p}=\sqrt{0.001056}\\\sigma_{ \hat p}=0.032[/tex]
Thus, the correct calculation and interpretation of the standard deviation of the sampling distribution of p hat is the sample proportion of women in this town giving birth to twins typically varies 0.032 from the true proportion, 0.12.

The slope of a line is 1/3.
What is the slope of a line perpendicular to this line?
Answer:
-3
Step-by-step explanation:
Slopes of a perpendicular line are the opposite reciprocal.
So, the opposite of 1/3 is -1/3.
Then the reciprocal of -1/3 is -3 (since -3 is -3/1).

The polygons are similar. The area of one polygon is given. Find the area of the other polygon
Answer:
Area of the other polygon = 4 in.²
Step-by-step explanation:
Area of the bigger polygon : Area of the smaller polygon = square of the side length of the bigger polygon : square of the corresponding side length of the smaller polygon
Let "x" represent the area of the smaller polygon
Thus, we have:
100/x = 20²/4²
100/x = 400/16
100/x = 25
Cross multiply
25x = 100
Divide both sides by 25
25x/25 = 100/25
x = 4
Area of the other polygon = 4 in.²

Shaquana is playing a board game. The probability that Shaquana will lose a turn on
her next turn is 12. Which word or phrase describes the probability that Shaquana
will lose a turn?
Answer:
Unlikely
Step-by-step explanation:
50/50 means that there is half a chance to loose a turn or 6/12 which is not the case.
Certain is definitely not correct as there is only 1/12 of a chance.
And impossible is not possible because it would have to be 0/12. There is still a chance to loose a turn with 1/12
Lana runs a business where she fixes bikes. She charges $15.75 per hour for her labor as well as a $25 flat fee for any parts she may use. Write and solve a linear equation to find the total cost for her customer if she fixes a bike from 8:30 a.m. to 12:30 p.m
Answer:
y = 15.75x + 25 is the linear equation
$88 would be the total cost
Step-by-step explanation:
First, create the equation using y = mx + b, where x is the number of hours:
y = 15.75x + 25 will be the equation, since the charge is $15.75 per hour and the flat fee is $25
There are 4 hours in between 8:30 AM and 12:30 PM, so to find the cost, plug in 4 as x and simplify:
y = 15.75x + 25
Plug in 4 as x:
y = 15.75(4) + 25
y = 63 + 25
y = 88
So, the total cost would be $88
