Answer:

y= $-\frac{4}{3}$ x -5

Step-by-step explanation:

9y=-12x-45

y=-12/9x-5

y= -4/3x-5

Write an equation for the line below. No Links. Thank you

TiliK225 [7]

Y=-1.5x+1.5
we can see the y-intercept is at (0, 1.5).
And when the line goes to the right 1 unit, it's at (1, 0), which is going down 1.5 units, meaning the slope is -1.5x. you can check this in desmos graphic calculator and you'll see the points on the line if you want

According to the United States Census Bureau, the average single-family home constructed in 2016 was 2,463 square feet. Carmen w

Dimas [21]

Using the t-distribution, it is found that the value of the test statistic is t = -87.3.

At the null hypothesis, it is <u>tested if the mean is of 2,463 square feet</u>, that is:

$H_0: \mu = 2463$

At the alternative hypothesis, it is <u>tested if the mean is smaller</u>, that is:

$H_1: \mu < 2463$ .

We have the <u>standard deviation for the sample</u>, hence, the <em>t-distribution</em> is used to solve this question.

The test statistic is given by:

$t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}$

The parameters are:

$\overline{x}$ is the sample mean.

$\mu$ is the value tested at the null hypothesis.

s is the standard deviation of the sample.

n is the sample size.

The values of the <em>parameters </em>are: $\overline{x} = 1640, \mu = 2463, s = 66, n = 49$ .

Hence, the value of the <em>test statistic</em> is:

$t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}$

$t = \frac{1640 - 2463}{\frac{66}{\sqrt{49}}}$

$t = -87.3$
