Question

1. Solve -2n + 5 > 7.
2. Kia experimental probability of striking out at baseball is 13%. Out of 30 times at bat about how many times will she strike out?

Answer 1

1. -2n + 5 > 7
Subtract 5 from both sides
-2n > 2
Divide both sides by -2
n < -1 (change inequality sign when dividing by a negative)

2. 13% of 30 =
.13 * 30 = 3.9
Approximately 4 times
