Answer:
56%
Step-by-step explanation:
90 ÷ 160
= 0.56
0.56 × 100
= 56%
The absolute value equation that represents the minimum and maximum scores is:
|x - 82| = 3.2.
<h3>What is the absolute value function?</h3>
The absolute value function is defined by:
It measures the distance of a point x to the origin.
For this problem, the distance between the minimum and the maximum scores and the mean is of 3.2, that is, the difference between these scores x and the mean of 82 is of 3.2, hence the absolute value equation that represents this situation is given by:
|x - 82| = 3.2.

Answer:
B. The student incorrectly calculated the scale factor to be –2
Step-by-step explanation:
Given that :
After a dilation with a center of (0, 0), a point was mapped as (4, –6) → (12, y).
The student determined y to be -2
If a figure dilated with a center of (0, 0) and scale factor k, then
(x , y) → (kx , ky)
(4, -6) → (12, y)


k = 3
Thus; the scale factor is 3
Now; the y-coordinate can now be calculated as;
ky = (3 × -6)
ky = -18
Therefore; the value of y = -18 and the student incorrectly calculated the scale factor to be -2.
Answer:
This company used 2265 gallons of soap this year
Step-by-step explanation:
50% of 4530

Soap used this year = 4530 - 2265 = 2265
