Using the relative frequency concept, it is found that:
- The number in the highlighted cell is: b. the revenue from sales of convertibles by Pluto Cars
- The relative frequency of this vehicle category compared with the total sales revenue of Pluto Cars is: b. 0.225.
<h3>What is a relative frequency?</h3>
A relative frequency is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
The number in the cell has bounds conversible and Pluto Cars, and the table represents the amount earned, that is, revenue, hence option b is correct.
The total revenue of Pluto Cars is of $80 million, with convertibles corresponding to $18 million, hence the relative frequency is given by:
r = 18/80 = 0.225.

1 1/2 is the correct answer
Given:
The figure of two semicircles with diameters 6 cm and 5 cm.
To find:
The area of the combined figure.
Solution:
It is given that the diameters of the semicircles are 6 cm and 5 cm so their radii are 3 cm and 2.5 cm respectively.
Area of a semicircle is:
So, the combined area of two semicircles with radii 3 cm and 2.5 cm is:
Round the value to the nearest tenth (one decimal place.
Therefore, the area of given figure is 24.0 sq. cm.
