Quality control, the cell phone manufacturer in exercise 60 wants to model the time between events. the mean number of defective cell phones is 2 per day. a) what model would you use to model the time between events? b) what would the probability be that the time to the next failure is 1 day or less? c) what is the mean time between failures?

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.

this is answer of 144 cubic meters

-1   1/6.   you dont subtract the denominators

step-by-step explanation:

363 square inches

step-by-step explanation:

surface area of a pyramid is b + 1/2ph

b is the area of the base: 11 x 11 = 121

p is the perimeter of the base: 11 + 11 + 11 + 11 = 44

h is the height of the pyramid: 11

121 + 1/2(44)(11)

121 + 242

363
