A. Use Equation (4.13) to write a formula for the median ,m of the lognormal distribution. What is the median for the load distribution of Exercise 79? b. Recalling that za is our notation for the 100(1 2 a) percentile of the standard normal distribution, write an expression for the 100(1 2 a) percentile of the lognormal distribution. In Exercise 79, what value will load exceed only 1% of the time?

step-by-step explanation:

i belive those are the ones that are under 90 degreese.

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
