I assume you meant 51 and older so I'm going based off on that. If you divide 72,345,000 by 100 then multiply that by 34(for the 34% of people 51 and older) then you get 24,597,300. So B

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

Contact [7]

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.

At your local farmers market , it costs $10 to rent to rent a stand , and $7 for every hour you stay there . If you paid a total

Arisa [49]

Subtract the rental fee, then divide the left over amount by the cost per hour.

38-10 = 28

28 / 7 = 4

The answer is 4 hours.

What is the radius of a sphere with a surface area of 100TCm ?

tensa zangetsu [6.8K]

The radius is 5cm

Step-by-step explanation:

The surface area of a sphere is given by:

$SA = 4\pi r^2$

Here

Given

SA = 100π cm^2

Putting the values in the formula

$100\pi = 4\pi r^2\\r^2 = \frac{100\pi}{4\pi}\\r^2 = 25$

Taking square root on both sides

$\sqrt{r^2} = \sqrt{25}\\r = 5 cm$

The radius is 5cm
