Answer:
30%
Step-by-step explanation:
This is how I would solve it: First you have to find 1 percent of $450. So:
450/100 = 4.5
Now, we have to find the difference between $450 & $315, which is $135. Now, we have to divide $135 by 4.5, which equals 30. So, the markdown is 30%. Basically:
450/100 = 4.5
450 - 315 = 135
135/4.5 = %30
The markdown is 30%.
The value of x when y =4 is 2
<h3>How to solve for x?</h3>
An inverse proportion is represented as:
k = yx
Where
k represents the constant of proportion
When y = 2, x = 4.
So, we have:
k =2 * 4
k = 8
Substitute k = 8 in k = yx
So, we have:
yx = 8
When y = 4, we have:
4x = 8
Divide by 4
x = 2
Hence, the value of x when y =4 is 2

Answer:
i think it is the control group sorry if i am wrong
Step-by-step explanation:
There are 71 adults drive fewer than 150 miles per week.
Solution:
From the histogram given,
Number of miles Number of adults
0 – 49 17
50 – 99 28
100 – 149 26
150 – 199 19
200 – 249 1
250 – 299 20
Fewer than 150 miles means below 150 miles.
Number of adults drive fewer than 150 miles = 17 + 28 + 26
= 71
Number of adults drive fewer than 150 miles = 71
There are 71 adults drive fewer than 150 miles per week.
