List a has 10 values, with average 82.2 and standard deviation 15.0. list b has 8 values, with average 106 and standard deviation 20.0. (a) suppose that the two lists are combined to produce a new list of 18 values. what is the average (mean) of this new list?

The average (mean) of the new list will be 92.777...

Explanation

List A has 10 values with average as 82.2 and list B has 8 values with average as 106.

So, the sum of 10 values in list A will be:  

and the sum of 8 values in list B will be:  

If the two lists are combined, then the sum of all 18 values in the new list

So, the average (mean) of this new list will be:  

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

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
