The lifespans of zebras in a particular zoo are normally distributed. The average zebra lives 20.520.5 20.5 20, point, 5 years; the standard deviation is 3.93.9 3.9 3, point, 9 years. Use the empirical rule (68−95−99.7%)(68 - 95 - 99.7\%) (68−95−99.7%) left parenthesis, 68, minus, 95, minus, 99, point, 7, percent, right parenthesis to estimate the probability of a zebra living longer than 32.232.2 32.2 32, point, 2 years.

step-by-step explanation:

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.  

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

you probably already have the answer but anyways it's b. 15.0
