Answer:
217 children and 481-217 = 264 adults
Step-by-step explanation:
The measures of spread include the range, quartiles and the interquartile range, variance and standard deviation. Let's consider each one by one.
<u>Interquartile Range: </u>
Given the Data -> First Quartile = 2, Third Quartile = 5
Interquartile Range = 5 - 2 = 3
<u>Range:</u> 8 - 1 = 7
<u>Variance: </u>
We start by determining the mean,

n = number of numbers in the set
Solving for the sum of squares is a long process, so I will skip over that portion and go right into solving for the variance.

5.3
<u>Standard Deviation</u>
We take the square root of the variance,

2.3
If you are not familiar with variance and standard deviation, just leave it.
Answer:
80+50P
Step-by-step explanation:
80 is fixed
50 is variable
1 device = 130
2 decices = 180
You need to write it out such as number 8 would be 10x10x10x10 so for every number on top you multiply the number by itself
