Answer:
Each student's contribution = $17
Each student will save $ 3
Step-by-step explanation:
Cost of the block of 5 tickets is $85.00.
Dividing the $ 85 by 5 would give the equal amount each would have to contribute.
$ 85/5=$ 17
Each will have to pay $ 17 to buy a block of 5 tickets for $85.00.
We can find the amount each will save by subtracting the amount to be shared by the 5 students from the amount paid by the 4 students.
They will save
$ 20-$17=
$3
Each of them will save $3 if they can get a fifth person to join them and the 5 people equally divide the price of the 5-ticket block.

I only got these the rest I don’t know because I just started learning it but these are correct.

C. Vertex (x,y). The vertex is right in the middle of the quadratic graph.
Part a)
The simple random sample of size n=36 is obtained from a population with

and

The sampling distribution of the sample means has a mean that is equal to mean of the population the sample has been drawn from.
Therefore the sampling distribution has a mean of

The standard error of the means becomes the standard deviation of the sampling distribution.

Part b) We want to find

We need to convert to z-score.

Part c)
We want to find

We convert to z-score and use the normal distribution table to find the corresponding area.

Part d)
We want to find :

We convert to z-scores and again use the standard normal distribution table.
