Does someone mind helping me with this problem? Thank you!

$\frac{10-(3 \cdot 2^2 - 23)}{(1 + 10^2)-2^2 \cdot 5^2} =$

$10-\left(3\cdot \:2^2-23\right) =10-\left(-11\right) =21$

$\left(1+10^2\right)-2^2\cdot \:5^2 = 101-2^2\cdot \:5^2 = 101-4\cdot \:5^2 =101-4\cdot \:25 =101-100 = 1$

$=\frac{21}{1}$

$\frac{a}{1}= a$

$=21$

I hope I helped you!

The number of days that homes stay on the market before they sell in Houston is bell-shaped with a mean equal to 56 days. Furthe

antoniya [11.8K]

Answer:

D. 8

Step-by-step explanation:

We have been given that the number of days that homes stay on the market before they sell in Houston is bell-shaped with a mean equal to 56 days. Further, 95 percent of all homes are on the market between 40 and 72 days.

As per empirical rule 95% of the data on bell curve lies between 2 standard deviations of mean.

So we can set an equation as:

$72-56=2\sigma$ or

$40-56=-2\sigma$

$16=2\sigma$

$\frac{16}{2}=\frac{2\sigma}{2}$

$8=\sigma$

$40-56=-2\sigma$

$-16=-2\sigma$

$\frac{-16}{-2}=\frac{-2\sigma}{-2}$

$8=\sigma$

Therefore, the standard deviation for our given data is 8 and option D is the correct choice.

Set it up 180=(7x+10)+ z because angle b is on the flat line and then solve for x (180-10, then 170/7) and you’ll get the value of x and from there you can put it in all
