2 answers:

8 0

There are many pairs you could do, but I'm going to choose this one:
$(-3a)(9a)$

You can multiply them together, and get (that's how you know if they are factors):
$(-3a)(9a) = -21a^2$

Hope this helped!

If Coach White coaches, the probability of being goalie is 0.55.

weeeeeb [17]

Answer:

49% probability that Mitchell will be a goalie today

Step-by-step explanation:

If Coach White coaches, the probability of being goalie is 0.55.

Coach White has a 70% probability of coaching.

If Coach Jackson coaches, the probability of being goalie is 0.35.

Coach Jackson has a 100-70 = 30% probability of coaching.

What is the probability that Mitchell will be a goalie today?

This is 55% of 70% plus 35% of 30%

Then

P = 0.55*0.7 + 0.35*0.3 = 0.49

49% probability that Mitchell will be a goalie today
