The speeds (in miles per hour) of motorists ticketed during one day on a five-mile stretch of highway are listed below.

80, 70, 89, 85, 85, 75, 72, 73, 80, 83, 86, 88, 88, 70, 89, 74, 75, 84, 73, 71

The mean speed is 79.5 mph with a standard deviation of 6.8 m.

If the police decide to only ticket people going 3 standard deviations or more above the standard deviation, what would the range be?

Your

19

Step-by-step explanation:

Range is solved by subtracting the lowest and highest numbers which int his case is 70 and 89 so that make 19

true

step-by-step explanation:

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
