Faith is working two summer jobs, making $13 per hour lifeguarding and $12 per hour washing cars. Last week Faith worked a total
san4es73 [151]

Answer:

Step-by-step explanation:

Let's call lifeguarding L and car washing W.  In order to write a system, we need to first separate the NUMBER of hours worked from the MONEY earned, because they are very different things.

If she works 10 hours, that is the number of hours worked between both jobs.  Therefore, the equation for the NUMBER of hours worked is

L + W = 10.

If she earns $13 an hour lifeguarding, the expression for that is 13L; if she earns $12 an hour car washing, the expression for that is 12W.  The MONEY she earned together by doing both those jobs is

13L + 12W = 124

There you go!

lapo4ka [179]

Answer:

A and B are independent events if P(A ∩ B) = 0.06

Step-by-step explanation:

Two events A and B are independent if the probability of occurrence of A does not influence the occurrence of B.

Mathematically it is written that A and B are independent events if and only if:

P(A ∩ B) = P(A)P(B)

We know that:

P(A) = 0.20

P(B) = 0.30

Then A and B are independent if:

P(A ∩ B) = (0.20)(0.30)

P(A ∩ B) = 0.06

Finally A and B are independent events if P(A ∩ B) = 0.06
