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

.25 * ________

And then we put the number in

.25 * 64 = 16

Which function represents g(x), a reflection of f(x) = 1/2(3)^x across the y-axis

aleksley [76]

They both have to be above the x axis, which makes B incorrect. B will be below the x axis. If you have a graphing calculator or know where there is one of the net, you can try it.

A and D are both wrong. The 1/2 does not become 2. What will happen is that 2 will make the graph wider.

There's only 1 answer left and that is
C <<<<<===== answer.
C reflects right across the y axis.
