Which equation(s) represents a nonproportional relationship? Select all that apply
O y=3x
O y=3x-2
O y=x+1
O y=-ax
Answer:
The correct answer is option one and option four.
Step-by-step explanation:
y=3x and y=-ax are equal because they are opposites and can match to the other by the same numbers. I hope you know what I mean by that, I prob didn't say it right. But the other two opstions are not correct because they are different kind of equations, (additions, subtraction, multiplication, and division) I hope you understand. Good luck on future questions!!

Find the value of c that completes the square.
m^2 + 32m + c
Answer:
c=256
Step-by-step explanation:
m²+32m+c=m²+32m+(32/2)²-(32/2)²+c
=m²+32m+16²-16²+c
=(m+16)²-256+c
for it to be a complete square -256+c=0
or c=256

A large nationwide company with 1200 employees claims that the number of days missed by its employees due to illness is below the national average of 7. A random sample of 40 employees resulted in a mean of 6.6 days with a standard deviation of 1.8. The hypothesis test resulted in a p-value of 0.084. Which of the following statements is true?
A. There is a 10% chance that the null hypothesis is true and a 8.3% chance that the alternative hypothesis is true.
B. There is a 8.3% chance that the mean number of days missed by employees at the company is below 7.
C. Since the probability that the mean number of days is below 7 is small, the null hypothesis is likely true.
D. If the mean number of days missed the company is 7 the probability of obtaining a sample mean of 66 days or lower is 0.063.
The last part of the question before the options is meant to be;
The hypothesis test using α = 0.1 resulted in a p-value of 0.084. Which of the following statements is true?
Answer:
B: There is a 8.3% chance that the mean number of days missed by employees at the company is below 7.
Step-by-step explanation:
Significance value is α = 0.1
p-value = 0.084
Now, we want to test the claims that the number of days missed by its employees due to illness is below the national average of 7.
Now the p-value is basically a probability.
Thus, p = 0.084 can be written as 8.4%
It seems this 8.4 is an approximate version of 8.3 because the options use 8.3%.
Thus, Option B is the closest answer.
Karen is planting a tree. She wants to use three guide wires to stabilize the tree. If Karen places the guide wires 8 feet up
the trunk and 6 feet from the base, how much total wire will she need for both guide wires?
Answer:
Karen will need 42 feet to use 3 guide wires to stabilize the tree.
Step-by-step explanation:
1 guide wire = 8 feet up + 6 feet from base
1 guide wire = 14 feet
3 guide wires = 14 feet + 14 feet + 14 feet
3 guide wires = 42 feet

You are to take a multiple-choice exam consisting of 100 questions with 2 possible responses to each question. Let x represent the number of correct responses on the test. A) What is your expected score on the exam?B) Compute the variance and standard deviation of x.
Answer:
50 ;
25 ;
5
Step-by-step explanation:
Given that:
Number of multiple choice questions = 100
Number of possible responses = 2
Hence, probability of success, p = 1/2 = 0.5
Using normal approximation :
The expected score = mean = n*p
Expected score (X) = 100 * 0.5 = 50
standard deviation = std(X) = √
Var(X) = n*p*q
q = 1 - p = 1 - 0.5 = 0.5
Variance = Var(X) = (100 * 0.5 * 0.5)
Var(X) = 25
Var(X) = 25
The Standard deviation (Std) = √Var(X)
Std(X) = √25
Std(X) = 5

Answer:
A.(-3,4) is your answer.
Step-by-step explanation:
-3x+4
For A:
x=-3
y=4
Plug in 3 where x is and multiply -3 x -3, which equals 0.
Then you plug in 4 where y is, so then your equation is (4=0+4)
Then you add 0 +4, which sum is 4.
Final equation is 4=4, so yes your answer is A. (-3 , 4)

Danielle created a painting using only similar hexagons.
Which statement about the hexagons must be true?
The hexagons are all the same size and shape.
The hexagons have corresponding sides that are proportional.
The hexagons have corresponding angles that are not congruent.
The hexagons are different shapes but the same size.
Answer:
The hexagons have corresponding sides that are proportional
Step-by-step explanation:
Hexagon is a polygon that consists of six sides and six angles.
Two polygons are said to be similar under the following conditions:
1. Corresponding angles of the hexagons are congruent.
2. Corresponding sides of the hexagons are proportional.
As hexagons are similar, the following statement must be true:
The hexagons have corresponding sides that are proportional.
Answer:
The hexagons have corresponding sides that are proportional.

a line passes through tge points (1,-3) and (4,6) what is the zero of this line ?
Answer:
The zero of the line is (2,0)
Step-by-step explanation:
The equation of a line passing through points (x1,y1) and (x2,y2) can be found as:
[tex]\displaystyle y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
We are given the points (1,-3) and (4,6). Substituting:
[tex]\displaystyle y+3=\frac{6+3}{4-1}(x-1)[/tex]
Operating:
[tex]\displaystyle y+3=\frac{9}{3}(x-1)[/tex]
[tex]y+3=3(x-1)[/tex]
The zero of this line can be found by making y=0 and solving for x:
0+3=3(x-1)
3=3x-3
Adding 3:
6=3x
Solving:
x = 2
The zero of the line is (2,0)
