Step-by-step explanation:

Given similar figures with ratio of sides = a : b , then

ratio of areas = a² : b²

ratio of sides = 15 ; 18 = 5 ; 6

The ratio of perimeters is equal to the ratio of sides, so

ratio of perimeters = 5 : 6

ratio of areas = 5² : 6² = 25 : 36

Using proportions, the selling prices are given as follows:

1. $46.92.

2. $15.29.

3. $17.16.

4. $20,280.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

To find the selling prices, we have to multiply the original prices by either 1.02(2% sales tax) or 1.04(4% sales tax), hence they are given as follows:

1. 46 x 1.02 = $46.92.

2. 14.99 x 1.02 = $15.29.

3. 16.50 x 1.04 = $17.16.

4. 19500 x 1.04 = $20,280.

gavmur [86]

Answer:

The percentage error in the prediction = 10.20%

Step-by-step explanation:

A sports broadcaster predicts a basketball team will score 88 point me in the next game.

If the team has actually scored 98 points we have to find the percentage error in the broadcaster's prediction.

The deviation of the prediction from the actual value = 98 - 88 = 10.

The formula for finding error percentage = $\frac{deviation from actual value}{prediction}$

= $\frac{10}{98} \times 100$

= 10.20 %

The percentage error = 10.20%
