Ion 5. the thickness of a conductive coating in micrometers has a density function of 600x-2 for 100 μm < x < 120 μm determine the mean and variance of the coating thickness. if the coating costs $0.50 per micrometer of thickness on each part, what is the expected cost of the coating per part

answer: 5100 just subtract

step-by-step explanation:

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.

spinner 1 spinner 2

1                     1

1                     2

1                     3

1                     4

2                   1

2                   2

2                   3

2                   4   = not 1, and 4

3                   1

3                   2

3                   3

3                   4 = not 1, and 4

only 2 outcomes have passed the given condition.
