3. A baseball diamond is a square that is 90 feet on each side. If a player throws the ball from 2nd base to home, how far will the ball travel? Round your answer to the nearest tenth.

90 feet

Step-by-step explanation:

180-90=90

the 3rd option is right

step-by-step explanation:

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
