Answer:
For part A-Emily would spend $22.70 on 22 feet of wire. For part B- Andy would spend $2.30 for 15 yards of wire.
Step-by-step explanation:
The cost is going down 10 cents by the foot, so getting 22 feet into 264 inches then having 165 into 164 and going up by the ten ending the number in four. Same with the yards in feet then the feet into yards and going down by 10. Hope it helps and makes sense.
What is the area of the circle?
Answer:
50.24 [tex]m^{2}[/tex]
Step-by-step explanation:
The formula to find the area of a circle is [tex]\pi r^{2}[/tex]. The radius of this circle is 4 because the radius is half the diameter. Since [tex]\pi[/tex] is an irrational number (whose digits goes on forever without repeating), people use use the first three numbers which are 3.14. Substitute 4 for r and 3.14 for [tex]\pi[/tex] into the formula, and you’ll get 50.24, and the answers also have the [tex]m^{2}[/tex] part too because your finding the area of a shape.
Hope this helps! :)
A production process produces 5% defective parts. A sample of five parts from the production process is selected. What is the probability that the sample contains exactly two defective parts
Answer:
0.0214
Step-by-step explanation:
Given that :
p = 5% = 0.05
Number of trials (n) = 5
probability that the sample contains exactly two defective parts
P(x = 2)
Using the binomial probability function :
P(x = x) = nCr * p^x * (1 - p)^(n-x)
P(x = 2) = 5C2 * 0.05^2 * (0.95)^3
P(x = 2) = 5C2 * 0.05^2 * (0.95)^3
P(x = 2) = 10 * 0.0025 * 0.857375
= 0.021434375
= 0.0214

Justine already owns 90 hair bands, and additional hair bands are priced at 5 for a dollar. With $124 to spend on new hair bands, how many total hair bands can Justine own? Write and solve an equation to find the answer.
Answer:
710 hairbands
Step-by-step explanation:
Total hairbands = (5*dollars spent) + 90
Max hairbands = (5 * 124) + 90
If we find that the null hypothesis, Upper H Subscript 0 Baseline colon beta Subscript j Baseline equals 0, cannot be rejected when testing the contribution of an individual regressor variable to the model, we usually should:___________
Answer:
Remove the variable from the Model
Step-by-step explanation:
Normally, when considering which variable to keep and which one to drop when considering testing of the contribution of an individual regressor variable to the model, generally speaking we use one explanatory variable for between 10-15 observations.
Now, before we run our regression, we would need to run correlation analysis between all explanatory variables to detect if there's any multicollinearity, and also between the dependent variable and the regressors in order to determine the most important predictors to be included in the regression.
So after the analysis, for the null hypothesis not to be rejected, we will remove the variable from the Model.

What is the slope of the line that passes through the points (-4,0) and (-4, -10)?
Write your answer in simplest form.
Answer:
the slope is undefined
Step-by-step explanation:
slope = y2 - y1
___________
x2 - x1
slope = (-10-0) / {-4 - (-4 ) }
slope = -10 / (-4 + 4)
slope = -10 / 0
slope = undefined

What is the answer, Please Help.
Answer:
r=144
Step-by-step explanation:
Cross multiply:
12 * 60 = r * 5
Simplifying
12 * 60 = r * 5
Multiply 12 * 60
720 = r * 5
Reorder the terms for easier multiplication:
720 = 5r
Solving
720 = 5r
Solving for variable 'r'.
Move all terms containing r to the left, all other terms to the right.
Add '-5r' to each side of the equation.
720 + -5r = 5r + -5r
Combine like terms: 5r + -5r = 0
720 + -5r = 0
Add '-720' to each side of the equation.
720 + -720 + -5r = 0 + -720
Combine like terms: 720 + -720 = 0
0 + -5r = 0 + -720
-5r = 0 + -720
Combine like terms: 0 + -720 = -720
-5r = -720
Divide each side by '-5'.
r = 144
Simplifying
r = 144
Answer:
r=144
Step-by-step explanation:
We need to find r. To do that me must make the top numbers the same.
We'll multiply
[tex] \frac{12}{r} \times \frac{5}{5 } = \frac{60}{5r} [/tex]
[tex] \frac{5}{60} \times \frac{12}{12} = \frac{60}{720} [/tex]
Since the top numbers are equal that means the bottoms are too.
So we can create the equation:
[tex]5r = 720[/tex]
Divide each side by 5
r=144
Hope this helps! If you have any questions on how I got my answer feel free to ask. Stay safe!

Which graph represents the equation y = x - 3
Answer:
b i did it
Step-by-step explanation:
Answer:
The correct answer is graph C.
Step-by-step explanation:
❌On a coordinate plane, a line goes through points (negative 3, 0) and (0, negative 3).
- the first point needs to be swapped in order to form x-3.
❌On a coordinate plane, a line goes through points (0, negative 1) and (1, 2).
- doesnt have a negative 3.
✔On a coordinate plane, a line goes through points (0, negative 3) and (3, 0).
- this answer has x as 0, and y as -3. which is equal to x-3.

The correct answer is shownLast week Len spent $18 to bowl 4 games. This week he spent $27 to bowl 6 games. Len owns his bowling ball and shoes, so he only has to pay for each game that he bowls. If each of these bowling games costs the same amount of money, what is the constant of proportionality between the money spent and the number of games played?
Answer:
$4.50/ g - Games
Step-by-step explanation:
$18
------------- = $4.50/g
4 g
$27
------- = $4.50/g
6 g
C(x) = ($4.50/game)x, where x is the # of games played.

Question 5 (4 points)
(04.02)
Determine whether the graph represents a proportional relationship. (4 points)
A graph is shown. The x-axis is labeled from 0 to 9. The y-axis is labeled from 0 to 10. Four points are shown on the graph on ordered pairs 0, 0 and 1, 3 and 2, 6 and 3, 7. These points are joined by a line. The label on the x-axis is Number of pans. The title on the y-axis is Number of cakes.
a
Yes, it is a proportional relationship because the graph goes through the origin
b
Yes, it is a proportional relationship because the graph is a straight line
c
No, it is not a proportional relationship because the graph is not a straight line
d
No, it is not a proportional relationship because the graph does not go through the origin
Answer:
C. It is not proportional because it is not a straight line.
Step-by-step explanation:
You can check to see if it is a straight line by setting up a table and ensuring that the values increase by the same amount every ordered pair.
------> The Answer Is C <------

There are 125 people on a mountain trail. If 55 people on the trail are children, what percentage of the people on the trail are children?
Answer:
44%
Step-by-step explanation:
.44 x 125 equals 55 n
Answer:
The percentage of people who were children = 44%
Step-by-step explanation:
Total people = 125Children on the trail = 55We need to determine the percentage of the people on the trail who are children.
All we need is to divide 55 by the total number of people i.e. 125 and then multiply the result by 100.so
Children percentage = 55 / 125 × 100
= 0.44 × 100
= 44%
Therefore, the percentage of people who were children = 44%
one room length 12.8 and breadth equals to 850 CM inside that room there is a bad length is 300 cm and breadth is 400 cm find the remaining surface area of the room and the answer will be in cm
Answer:
[tex]Area = 968000cm^2[/tex]
Step-by-step explanation:
To be able to answer this question properly. I'll assume the length of the room is in meters.
So for the room, we have:
[tex]Length = 12.8m[/tex]
[tex]Breadth = 850cm[/tex]
For the bed, we have:
[tex]Length = 300cm[/tex]
[tex]Breadth = 400cm[/tex]
First, we calculate the surface area of the room.
[tex]A_1 = 12.8m * 850cm[/tex]
Convert all units to cm
[tex]A_1= 12.8*100cm * 850cm[/tex]
[tex]A_1= 1 088 000 cm^2[/tex]
Next, we calculate the area of the bed
[tex]A_2 = 300cm * 400cm[/tex]
[tex]A_2 = 120000cm^2[/tex]
The area of the space left is the difference between A1 and A2
[tex]Area = A_1 - A_2[/tex]
[tex]Area = 1088000cm^2 - 120000cm^2[/tex]
[tex]Area = 968000cm^2[/tex]
