Answer 1

Answer: 0.021

Step-by-step 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 :-

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

Hence, the required answer is 0.021.
