Answer 2

Answer: 0.021

Explanation:

Given Table:

Sales ($ million)

Company Convertibles SUVs Sedans Mini Trucks Marginal Totals

Allison 45 28 19 36 128

B&B Motors 65 22 15 9 111

Pluto Cars 18 25 27 10 80

Panther Motors 40 26 34 12 112

Marginal Totals 168 101 95 67 431

From the above table, the total sales revenue earned by all four companies = $431 million

The revenue earned by B&B Motors from sales of mini trucks = $9 million.

Then, the relative frequency of the revenue earned by B&B Motors from sales of mini trucks compared to the total sales revenue earned by all four companies will be :-

`\frac{\text{Revenue earned by B&B Motors from sales of mini trucks}}{\text{Total revenue}}\\\\=\frac{\$9\text{ million}}{\$431\text{ million}}\\\\=(9)/(431)=0.0208816705336\approx0.021`

Hence, the required answer is 0.021.
