Answer:

ans=13.59%

Step-by-step explanation:

The 68-95-99.7 rule states that, when X is an observation from a random bell-shaped (normally distributed) value with mean $\mu$ and standard deviation $\sigma$ , we have these following probabilities

$Pr(\mu - \sigma \leq X \leq \mu + \sigma) = 0.6827$

$Pr(\mu - 2\sigma \leq X \leq \mu + 2\sigma) = 0.9545$

$Pr(\mu - 3\sigma \leq X \leq \mu + 3\sigma) = 0.9973$

In our problem, we have that:

The distribution of the number of months in service for the fleet of cars is bell-shaped and has a mean of 53 months and a standard deviation of 11 months

So $\mu = 53, \sigma = 11$

So:

$Pr(53-11 \leq X \leq 53+11) = 0.6827$

$Pr(53 - 22 \leq X \leq 53 + 22) = 0.9545$

$Pr(53 - 33 \leq X \leq 53 + 33) = 0.9973$

-----------

$Pr(42 \leq X \leq 64) = 0.6827$

$Pr(31 \leq X \leq 75) = 0.9545$

$Pr(20 \leq X \leq 86) = 0.9973$

-----

What is the approximate percentage of cars that remain in service between 64 and 75 months?

Between 64 and 75 minutes is between one and two standard deviations above the mean.

We have $Pr(31 \leq X \leq 75) = 0.9545 = 0.9545$ subtracted by $Pr(42 \leq X \leq 64) = 0.6827$ is the percentage of cars that remain in service between one and two standard deviation, both above and below the mean.

To find just the percentage above the mean, we divide this value by 2

So:

$P = {0.9545 - 0.6827}{2} = 0.1359$

The approximate percentage of cars that remain in service between 64 and 75 months is 13.59%.

The function C(x) = 25.50x + 50 models the total cost for a cleaning company to clean a house, where x is the number of hours it

vodomira [7]

Answer:

<em>The average rate of change is $25.5 per hour, option B.</em>

Step-by-step explanation:

<u>Average Rate of Change </u>

When we are explicitly given some function C(x), we sometimes need to know the rate of change of C when x goes from $x=x_1$ to $x=x_2$ . It can be computed as the slope of a line .

$\displaystyle m=\frac{C(x_2)-C(x_1)}{x_2-x_1}$

The provided function is

$C(x)=25.50x + 50$

We are required to compute the average rate of change between the points

$x_1=3\ ,\ x_2=9$

Let's compute

$C(3)=25.50(3) + 50=126.5$

$C(9)=25.50(9) + 50=279.5$

$\displaystyle m=\frac{279.5-126.5}{9-3}$

$\displaystyle m=\frac{153}{6}=25.5$

The average rate of change is $25.5 per hour, option B.

Explain how you could mentally find 8 x 45 by using the distributive property

dangina [55]

First, break up 45 into 40 and 5 then multipy 8(40) which equals 320 and multipy 8(5) which equals 40. Thrn add 320+40 to get the product 360.
Hope this helped
