kogti [31]

The percentage of the payments made were due to interest is 32.6 %. Then the correct option is B.

<h3>What is the percentage?</h3>

The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.

The following table shows a portion of a five-year amortization schedule.

A 5-year amortization schedule.

Loan amount or principal: 10,900 dollars.

The interest rate on loan: 10. 95 percent.

The table will be

Month         Payment         Principal         Interest         Balance

  15               236.72            155.87            80.85           8704.27

  16               236.72            157.29            79.43           8546.98

  17               236.72            158.73            77.99            8388.25

  18               236.72            160.18            76.54            8228.07

  19               236.72            161.64            75.08            80.66.43

  20              236.72            163.11             73.61             7903.32

Total payment = 6 × 236.72 = $ 1420.32

Total interest = 80.85 + 79.43 + 77.99 + 76.56 + 75.08 + 73.61

Total interest = $ 463.38

Then the percentage will be

\rm Percentage = \dfrac{463.38}{1420.32}*100\\\\Percentage = 32.625 \approx  32.6\ \%

You need a mean of at least 90 points to advance to the next round of the touch-screen trivia. What score in the fifth game will
lianna [129]

Answer:

At least 98 is needed in the 5th game

Step-by-step explanation:

The missing parameters are:

Game\ 1 = 95

Game\ 2 = 91

Game\ 3 = 77

Game\ 4 =89

Mean = 90 at least

Required

The score in game 5 to make you advance

Mean is calculated as:

Mean = \frac{\sum x}{n}

So, we have:

Mean = \frac{95 + 91 + 77 + 89 + Game\ 5}{5}

Mean = \frac{352 + Game\ 5}{5}

The mean must be at least 90.

So, we have:

\frac{352 + Game\ 5}{5} \ge 90

Multiply both sides by 5

5 * \frac{352 + Game\ 5}{5} \ge 90 * 5

352 + Game\ 5 \ge 450

Make Game 5 the subject

Game\ 5 \ge450 - 352

Game\ 5 \ge 98

<em>At least 98 is needed in the 5th game</em>
