Cal Lury owes $25,000 now. A lender will carry the debt for four more years at 10 percent interest. That is, in this particular

vitfil [10]

Answer:

$6,185.31

Explanation:

Value of debt at end of 4 years = $25,000 * (1 + 10%)^4

Value of debt at end of 4 years = $25,000 * (1.10^4)

Value of debt at end of 4 years = $25,000 * 1.4641

Value of debt at end of 4 years = $36,602.50

Let x be the annual payments

x * [1 - (1 + 13%)^-12] / 13% = $36,602.50

x * [1 - (1.13)^-12] / 13% = $36,602.50

x * [1 - 0.2307059] / 13% = $36,602.50

x * 0.7692941/0.13 = $36,602.50

x * 5.91764692 = $36,602.50

x = $36,602.50/5.91764692

x = 6185.313266375142

x = $6,185.31

So therefore, his annual payment will be $6,185.31.

bija089 [108]

Answer:

7.5 to 467.5.

Explanation:

Please note that In order to be fast, I make use of excel during the Calculation.

So, the first thing to do is to make sure that the observation is arranged in an increasing order.

Step one: Calculate the value for J1 and J3.

Know that J1 = J3. Where J3 = 3rd quartile.

Hence, J1 = 1st QUARTILE = QUARTILE. EXC (data, 1) = 18.

Also, J3 = QUARTILE. EXC(data, 3). = 29.5.

Therefore, the difference between the first quartile and the third QUARTILE = 29.5 - 18 = 11.5.

Step two: calculate the value for the higher fence and the lower fence respectively.

Thus, for the higher fence we have;

J3 + 1.5( 11.5).

= 29.5 + 1.5(11.5).

= 46.75.= (46.75 × 10) = 467.5).

Then, for the lower fence;

J1 - 1.5( 11.5).

= 18 - 1.5(11.5).

= 0.75 = (.75 × 10) = 7.5.
