Answer:
a) 32
b) 67.613
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
