The average length of time it takes to complete a Ph. D. in statistics is 5.2 years, with a standard deviation of 0.7 years. In a random sample of 40 individuals with a Ph. D. in statistics, what is the 90th percentile of the sum total amount of time that all 40 spent in grad school

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
