Step-by-step explanation:
Since 1 mi. equals 5,280 feet, you divide 5,280 by 2 to get half of a mile.
5,280 / 2 = 2,640 is half of a mile
Then add to get the answer:
5,280 + 2,640 = 7,920
Therefore, your answer is 7,920, 7,920 is 1.5 miles.
First you would do 3-9 which is -6 then -4-1 which is -5 then since the parenthesis are close to each other you would multiply and you should get
30

Adding or subtracting a constant from each value of a distribution changes the mean, but not the standard deviation.
The standard deviation will equal 3.
