Hello!
First we have to find the median
We have to order the numbers from least to greatest
72, 83, 87, 90, 97, 101, 114, 117, 142
The median is 97
Next we have to find quartile 1
you look for the median for the numbers under 97
It is 83 and 87
You get the average
83 + 87 = 170
170 / 2 = 85
quartile 1 is 85
Next we find quartile 3
Look for the median for the numbers above 97
The numbers are 114 and 117
Get the average
114 + 117 = 231
231/2 = 115.5
Now you find the range between the quartiles
You do quartile 3 - quartile 1
115.5 - 85 = 30.5
The answer is 30.5
Hope this helps!
Answer:
A) 61.68
Step-by-step explanation:
This is an exponential decay of 0.875. The way to know that is to get that is
(Pick a random number and divide by the number to the left of it) From there, there is a 12 hour difference from 7 am to 7pm! Divide 306.25/0.875 and divide it by 0.875 by the answer of that each time 12 times. The exact answer is 61.68402914
