Answer:The new cost per person= $19 when there are 12 people

Step-by-step explanation:

Step 1

Let Number of people be rep as N

And Cost per person = C

such that the relationship of  number of people which varies inversely with the cost per person is given as

N∝ 1/C

Introducing constant of proportionality, k, we have that

N= K/C

such that when there were 4 people the cost per person was $57, K would be

N= K/C

4 = K /57

k= 57 X 4

k=228

Step 2

Therefore If the number of people changed to 12, cost per person would be

N= K/C

12= 228 / C

C= 228/12

C= 19

The new cost per person= $19 when there are 12 people

<u>Question</u>

Suppose that a committee is studying whether or not there is excessive time waste in our judicial system. It is interested in the mean amount of time individuals spend at the courthouse waiting to be called for jury duty. The committee randomly surveyed 81 people who recently served as jurors. The sample mean wait time was 4 hours with a sample standard deviation of 1.2 hours. Define the random variables X and \bar{X} in words.

Answer:

(B)

  • X is the amount of time an individual waits at the courthouse to be called for service.
  • \bar{X}  is the mean wait time for a sample of individuals.

Step-by-step explanation:

The random variable X is the amount of time for which each of the prospective juror waits at the courthouse before being called for service.

\bar{X}  is the mean wait time for a the given sample of individuals. In the case given,

3 1/3 (2 1/5 x−4 2/3 )−5 5/6 =0
cestrela7 [59]
3 1/3(2 1/5x-4 2/3)-5 5/6=0
Since you can't subtract 2 1/5x and 4 2/3 together you would use the next step in the order of operations which is multiplication.
(3 1/3)(2 1/5x)=(10/3)(11/5x)=110/15x
(3 1/3)(4 2/3)=(10/3)(14/3)=140/9
7 5/15x - 15 5/9
Then you would subtract 7 5/15x - 15 5/9 with 5 5/6.
7 5/15x -15 5/9 - 5 5/6=
15 5/9=15 10/18
5 5/6=5 15/18
7 5/15x - 15 10/18 - 5 15/18=
7 5/15x - 21 7/18=0
Then you would try to solve for x by isolating it on one side.
7 5/15x=21 7/18
110/15x=385/18
x=(385/18)(15/110)
x=5775/1980
x= 2 1815/1980
x= 2 363/396
x= 2 121/132
x= 2 11/12
I hope you understood!!!!
