Achef asks for your advice given that you are a student of business statistics. he tells you that it takes approximately a normally distributed mean of 35 minutes and a standard deviation of 2 minutes to cook a spaguetti and meatball meal. convert 31 minutes into a z-score given the z-score formula.

 -2

Step-by-step explanation:

Given : A chef asks for your advice given that you are a student of business statistics.

He tells you that it takes approximately a normally distributed . and to cook a spaguetti and meatball meal.

Let x be a random variable that represents the time to cook a spaguetti and meatball meal.

Using the formula , the value of z for x= 31 we get

Hence, the z-score for 31 minutes = -2

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
