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

a) 32

b) 67.613

Step-by-step explanation:

In Game 3, Emerson struck out 42 times in 140 times at-bat.

Part A

Drag numbers to complete the proportion to represent the percent of strikeouts per at-bats.

Numbers may be used once or not at all.

Part B

What percentage of times at bat did Emerson actually hit the ball?

Part A

Total number of strikeouts= 30+40+42= 112

Total number of at bats = 90+120+140= 350

strikeouts : times

112: 350

p:100

Using cross product rule

p/100= 112/350

p * 350= 112*100

or p= 11200/350= 32

It means that there were 32 strikeouts if 100 times were bat at hits.

Part B:

Total number of strikeouts= 30+40+42= 112

Total number of at bats = 90+120+140= 350

But we need the percentage of times at bat hit

Therefore

Hits= times - strikeouts= 350-112= 238

Percentage = 238/352*100= 67.613

Check

The above answers are correct because

100-32 = 68

68 ≅ 67.613
