Answer:

Being male and preferring brand A are independent.

Because: if independent then P(male and brand A) = P(male) P(brand A) = 0.48 * 0.75 = 0.36 and that is true (= value in the table)  

P(male|brand A)=0.36/0.75=0.48 = P(male)

How long will it take Greg to earn $500.00 round to the nearest hour
Mrrafil [7]

Answer:

56 hours

Step-by-step explanation:

we know that  

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y/x=k or y=kx

Let

x -----> the number of hours

y ----> the amount earned in dollars

This problem represent a proportional relationship between the variable x and the variable y

Find the value of the constant of proportionality k

k=y/x

For (3,27) ----> k=27/3=9\ \$/h

For (9,81) ----> k=81/9=9\ \$/h

For (21,189) ----> k=189/21=9\ \$/h

The constant of proportionality k is 9

The linear equation is

y=9x

For y=$500

substitute in the equation and solve for x

500=9x

Divide by 9 both sides

x=56\ hours
