Set up a proportion table. for: at a hardware store, the price of 3 feet of rope is $1.20. what is the price of 8 feet of rope?

3/1.2 = 8/x

3x = 9.6

x = 3.2

answer: 20

step-by-step explanation: subtract the minimum date value from the maximum data value to find the date range. in this casem the date range is 42 - 22 = 20

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
