Donald bought a box of golf balls for $9.30. There were 18 golf balls in the box. About how much did each golf ball cost? Rename the decimal dividend as a whole number that is compatible with the divisor to estimate the quotient.

$0.52 per ball approx.

Step-by-step explanation:

Step one:

given data

we are told that the cost of the box of gulf is $9.30

and there are 18 golf balls in the box

Required:

we are to determine the cost of each ball

the cost is

Step two:

Cost per ball= total cost of the box/number of ball

Cost=9.30/18

Cost= $0.52 per ball approx.

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
