Consider a quality inspection process of a manufacturing plant. The inspector tests each product insequence until she nds the rst failure and then stops. Let N be the number of tests. Assume that all testsare independent with probability of failure p = 0:2. Find the PMF pN(n). For the next two parts, supposethat you are told that there have been at least 15 consecutive tests without a failure.

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.

yx = 36

step-by-step explanation:

cos f = opposite side/ hypotenuse

cos f = yw / yx

we know cos f = 4/9 and yw =16

4/9 = 16/yx

multiply each side by yx

4/9 yx = 16/ yx * yx

4/9 yx = 16

multiply each side by 9/4

9/4 * 4/9 yx = 16 *9/4

yx = 36
