Answer:

y will equal 29 + 29 - 2(29) which equals 0

when y = 0, the solution is the x-axis

hope this helps! <3

Hi there~<br><br> Divide: <br><br> 4 1/3 ÷ 1 2/9

siniylev [52]

Make them both improper fractions
13/3 divided by 11/9
Divide = multiply reciprocal
13/3 * 9/11 = 117/11 = 10 7/11

Which graph is correct?

fredd [130]

C
There are many ways to see it. First is the dotted and solid lines
The dotted lines mean that it doesn’t include the answer while the dotted line says it does.
When something is greater it’s going to be shaded on top of the line and when something is less it’s going to be shaded below the line

Suppose that the number of square feet per house are normally distributed with an unknown mean and standard deviation. A random

astraxan [27]

Answer:

1. The margin of error is of 66.96 square feet.

2. The 95% confidence interval estimate for the population mean using the Student's t-distribution is between 1433.04 square feet and 1566.96 square feet

Step-by-step explanation:

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 22 - 1 = 21

95% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 21 degrees of freedom(y-axis) and a confidence level of $1 - \frac{1 - 0.95}{2} = 0.975$ . So we have T = 2.08

The margin of error is:

$M = T\frac{s}{\sqrt{n}} = 2.08*\frac{151}{\sqrt{22}} = 66.96$

In which s is the standard deviation of the sample.

The margin of error is of 66.96 square feet.

The lower end of the interval is the sample mean subtracted by M. So it is 1500 - 66.96 = 1433.04 square feet

The upper end of the interval is the sample mean added to M. So it is 1500 + 314 = 1566.96 square feet

The 95% confidence interval estimate for the population mean using the Student's t-distribution is between 1433.04 square feet and 1566.96 square feet
