Components that are critical for the operation of electrical systems are replaced immediately upon failure. Suppose that the life time of a certain such component has a mean of 100 hours and a standard deviation of 55 hours. How many of these components must be in stock to ensure a probability that at least 0.95 for the system to be in continuous operation for at least the next 2000 hours

the monthly balance will be $75,000

wth is with the little mtn top and what are you talking about like fix your words and accually make sence with them and i like was in a completly different question like three times like it seems like your ilitteret

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
