D is correct. The median is 28, Q1 is 22, Q3 is 38
Answer:
The percent decrease was 20%
Step-by-step explanation:
In order to find this, use the percent change equation.
(New - Old)/(Old) * 100 = % Change
Now input 48 for the New price and 60 for the Old price.
(48 - 60)/(60) * 100 = % Change
12/60 * 100 = % Change
.2 * 100 = % Change
20 = % Change
The second graph because 2x5=10, 4x5=20, 6x5=30!
Option a is correct. The calculated answer is 0.150
<h3>How to get the value using the cdf</h3>
In order to get P(0.5 ≤ X ≤ 1.5).
This can be rewritten as
p = 0.5
and P = 1.5
We have the equation as

This would be written as
1.5²/16 - 0.5²/16
= 0.1406 - 0.015625
= 0.124975
This is approximately 0.1250
