The data set below provides the monthly rent (in dollars) paid by 5 tenants. 879 , 920 , 940 , 950 , 990 Suppose the rent for on

MrRa [10]

Answer:

Mean before the rent changes = $935.8

Mean after the rent changes = $970.8

Step-by-step explanation:

Mean = sum of all data values / number of data values in a given data set

✔️Data set consisting of the rents of 5 tenants: 879 , 920 , 940 , 950 , 990

Mean before the rent changes = (879 + 920 + 940 + 950 + 990)/5 = 4,679/5 = 935.8

Mean before the rent changes = $935.8

✔️If one of the tenants rent changes from $940 to $1,115, the new data set would be:

879 , 920 , 1,115 , 950 , 990

Mean after the rent changes = (879 + 920 + 1,115 + 950 + 990)/5 = 4,854/5 = 970.8

Mean after the rent changes = $970.8

Wanda has a DRF of 1.75 and a 6 month basic rate of 750. What is her annual premium?

Sedaia [141]

Answer:

The calculation for annual premium is explained below:

Step-by-step explanation:

Here we are given as:

DRF = 1.75

time period = 6 month = 2 times a year

basic rate = 750

Her annual premium will be: $\frac{1.75*750}{2}$

= 2625

Hence Wanda's annual premium will be 2625.

vagabundo [1.1K]

Answer:

a. x1,x2,x3,x4

b. 20x1 + 24x2 + 28x3

c. x1 +x2 ≥ 25

Step-by-step explanation:

At a time that spans from 1 to 5pm, we have timing as follows:

1pm - 2pm = x1

2pm - 3pm = x2

3pm - 4pm = x3

4pm - 5pm = x4

a. The decision variables are x1, x2, x3, x4 and these are the number of people for each shift.

b. The objective function is the minimum cost which is

20x1 + 24x2 + 28x3

c. The constraints for each has been listed

1 - 2pm, x1 ≥ 20 workers

2 - 3pm, x1 + x2 ≥ 25

3 - 4pm, x2 + x3 ≥ 25

4 - 5pm, x3 ≥ 30

The question asked us to write the one for 2-3pm, which is x1 + x2 ≥ 25

A company currently has no items in inventory. The demand for the next four months is 200, 400, 250, and 350 units. Assuming a l

Butoxors [25]

The total demand is: 200 + 400 + 250 + 350 = 1200

Production is 350 a month.

Multiply by the 4 months: 350 x 4 = 1400.

Now subtract the demand from the total production:

1400 - 1200 = 200 left for inventory.

The answer is b. 200
