Answer:
<u>So option 4; </u>
<u> is the correct option</u>
Step-by-step explanation:
First, we need to convert 
so it's denominator is 100. To do so, we will multiply the numerator and denominator by 10
Second, we need to add the two fractions to get the current total distance walked. Remember, when adding fractions, the denominator does not change.
Now that we have the total distance walked, we need to subtract that to 1 mile. 
So option 4; is the correct option
Mean = (14 + 16 + 7 + 9 + 11 + 13 + 8 + 10) ÷ 8 = 11
Variance =
[ (14-11)²+(16-11)²+(7-11)²+(9-11)²+(11-11)²+(13-11)²+(8-11)²+(10-11)² ]/7 = 9.71
Answer: 9.71
The answer to the question is d
54 students in each bus.
