Which type of visual aid would you use to show changes over time?

son4ous [18]

A plot in Cartesian axes.
This kind of graph has two exes: x (horizontal) and y (vertical). X represents the independent variable, in this case: time. Y represents the dependent variable, which is the one that is changing over time. For example, you can make this graph with temperature along the year. You will usually have higher temperatures in summer, which will be represented in the upper part of the graph, and lower temperatures in winter, which will be represented in the bottom part of the graph. January will be on the left and December will be on the right.

Nat2105 [25]

Answer:

B. decrease

Explanation:

The subsidiary's cost of purchasing materials measured in Australian dollar will decrease. The subsidiary in Australia sells mobile homes. It borrows funds from local bank and purchases material from Hong Kong and pays Hong Kong in HK$ which is tied to US dollar. So when Australian dollar appreciates against the Hong Kong dollar, it will appreciate against US dollar as the Hong Kong dollar is tied to US dollar. The subsidiary will pay decreased cost of purchasing material due to appreciations of A$ by increasing interest rate in Australia.

Sindrei [870]

Answer:

The EOQ is 353 units

Explanation:

The economic order quantity or EOQ is the quantoty that minimized the holding and ordering cost for invetory.

The formula for EOQ is,

EOQ = √(2*D*O) / H

Where,

D is the annual demand in units
O is the ordering cost per order
H is the holding cost per unit per annum

The annual demand of oil filters by Sam is,

Annual demand = 52 * 150 = 7800 filters

The EOQ for Sam Auto Shop is,

EOQ = √(2*7800*16) / 2

EOQ = 353.27 Units rounded off to 353 units

A small market orders copies of a certain magazine for its magazine rack each week. Let X 5 demand for the magazine, with pmf Su

Oksanka [162]

Answer:

See explanation below.

Explanation:

Let X the random variable that represent the demand for the magazine, the pmf for X is given by:

X 1 2 3 4 5 6

P(X) 1/15 2/15 3/15 4/15 3/15 2/15

3 magazines

For this case the total spent is 2*3 = $ 6

And the net revenue for this case would be:

$4-$6 = -$2 , X=1 (demand 1)

$4*2-$6 = $2 , X=2 (demand 2)

$4*3-$6 = $6 , X=3 (demand 3)

For the values of X=4,5,6 the net revenue will be $6 since the number of magazines is 3

And the expected value for the net revenue would be:

$E(R) = \frac{1}{15} *(-2) +\frac{2}{15} *(2) +\frac{3}{15}*(6) + \frac{4}{15}*(6) +\frac{3}{15}*(6) +\frac{2}{15}*(6) = \frac{74}{15}=4.93$

4 magazines

For this case the total spent is 2*4 = $ 8

And the net revenue for this case would be:

$4-$8 = -$4 , X=1 (demand 1)

$4*2-$8 = $0 , X=2 (demand 2)

$4*3-$8 = $4 , X=3 (demand 3)

$4*4-$8 = $8 , X=4 (demand 4)

For the values of X=5,6 the net revenue will be $8 since the number of magazines is 4

And the expected value for the net revenue would be:

$E(R) = \frac{1}{15} *(-4) +\frac{2}{15} *(0) +\frac{3}{15}*(4) + \frac{4}{15}*(8) +\frac{3}{15}*(8) +\frac{2}{15}*(8) = \frac{80}{15}=5.33$

As as we can see we have a higher expected value for the case with 4 magazines.
