In Game 1, Emerson struck out 30 times in 90 times at bat. In Game 2, he struck out 40 times in 120 times at bat. In Game 3, Emerson struck out 42 times in 140 times at bat. What percentage of times at bat did Emerson actually hit the ball? a. 39% b. 85% c. 68% d. 45%

Emerson actually hit the ball 32% of times at bat.

Since in Game 1, Emerson struck out 30 times in 90 times at bat; in Game 2, he struck out 40 times in 120 times at bat; and in Game 3, Emerson struck out 42 times in 140 times at bat; To determine what percentage of times at bat did Emerson actually hit the ball, the following calculation must be performed:

Therefore, Emerson actually hit the ball 32% of times at bat.

68%

Step-by-step explanation:

Given that :

Game 1 = 30 times in 90 times at bat

Game 2 = 40 times in 120 times at bat

Game 3 = 42 times in 140 times at bat

Total strike outs = (30 + 40 + 42) = 112

Total time at bat = (90 + 120 + 140) = 350

Total hits = total time at bats - total strike outs

Total hits = 350 - 112 = 238

Percentage hits :

(Total hits / total time at bats) * 100%

(238 / 350) * 100%

0.68 * 100%

= 68%

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
