X should equal -13.33. Y is correct, 13.33
Y= 18x+35
Y is the total
X is the number of hours that was rented
Answer:
s = 12t/33
Step-by-step explanation:
multiply through by 4 In order to remove the denominator from the equation
12t - s = 32s
making s the subject
32s + s = 12t
33s = 12t
s = 12t/33
Assuming a standard normal distribution, the positive value of interest will be that corresponding to the 50 + 36/2 = 68th percentile. A suitable probability calculator will give that value as 0.46770.
The values that are within ±0.46770 standard deviations from the mean will have a probability of 0.36.

Solving (a): The entry C22
First, matrix C represents the inventory at the end of July.
The entry of C is calculated as:
i.e.
Item C22 means the entry at the second row and the second column.
From the matrix
Solving (b): The maximum A31 possible.
From the given data, we have:
From the matrices above.
A31 means entry at the 3rd row and 1st column.
So, the possible values of A31 are:
and
By comparison, 376 > 54
So:
