If a 4 pound toast takes 150 minutes to cook how long should a five pound roast take

187.5

Step-by-step explanation:

150/4 = 37.5

1 pound = 37,5 mins

37.5 x 5 = 187.5

187.5

Step by Step

37.5 * 5 = 187.5

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
