The amount of time that a customer waits on hold at a call center can be modeled by a uniform distribution on the interval from

0 seconds to 120 seconds.
A) Draw a density curve to model the amount of time that a randomly selected customer waits on hold. Be sure to include scales on both axes.
B) About what percent of the time does a customer have to wait between 100 and 120 seconds?

Using the uniform distribution, we have that:

a) The density curve is given at the end of this question.

b) 16.67% of the time does a customer have to wait between 100 and 120 seconds.

-----------------

The uniform distribution has two bounds, a and b, and the probability of finding a value between c and d is given by:

P(c \leq X \leq d) = \frac{d - c}{b - a}

  • Uniform distribution on the interval of 0 to 120 seconds, thus a = 0, b = 120.

The proportion between 100 and 120 seconds is:

P(100 \leq X \leq 120) = \frac{120 - 100}{120 - 0} = \frac{1}{6} = 0.1667

0.1667*100% = 16.67%

16.67% of the time does a customer have to wait between 100 and 120 seconds.

Answer:

Step-by-step explanation:

problem 4

Velocity is +2.0m/s and constant acceleration is -0.5m/s^2

For every second the velocity drop by 0.5 m/s, so after 2 seconds the velocity is  1 m/s.

problem 5

Accelerate from rest to 28m/s means go from 0 to 28m/s so with

a constant acceleration of 5.5 m/s^2 it will take 5.09 second

If I = PRT/100, MAKE R THE SUBJECT OF THE FORMULA.​
Nonamiya [84]

Answer:

R = \frac{100I}{PT}

Step-by-step explanation:

I = \frac{PRT}{100} ( multiply both sides by 100 to clear the fraction )

100I = PRT ( isolate R by dividing both sides by PT )

\frac{100I}{PT} = R
