Find the probability that the pitcher will
throw more than 3 pitches to a batter.
Enter your answer as a percent or a decimal.
p = [?]

25% or 0.25

Step-by-step explanation:

P( more than 3 pitches) is the sum of number of 4 and 5 pitches/ the total number of pitches.

The total number of pitches is 100. The sum of number of 4 and 5 is 25 so the probability is

25/100=0.25

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
