The standard deviation of a dataset is the square root of the variance.
The standard deviation of the same set of data is 4
The variance is given as:
Take the square root of both sides to calculate the standard deviation
Substitute 16 for .
So, we have:
Take the positive square root of 16
Hence, the standard deviation of the same set of data is 4

For example
2 pencils cost one dollar
Then one pencil costs 50 cents. We just found out the cost per unit of the pencil.
Hope that helped :)
#1= -4 and 2

a. A=7560(t)+5550
work: 45 × 24 × 7 =7650
b. t=12.5
100,000=7650(t)+5500 (subtract)
94450=7650(t) (divide)
12.493386243 (round)
12.5
