$y - 9 = \frac{1}{5} (x - 2) \\$

$y - 9 = \frac{1}{5} x - \frac{2}{5} \\$

Add sides 9

$y -9 + 9 = \frac{1}{5} x - 0.4 + 9 \\$

$y = \frac{1}{5} x + 8.6 \\$

$y = \frac{1}{5} x + \frac{43}{5} \\$

This is the slope-intercept form.

<h2><u>Remember from now on</u> ,</h2>

The coefficient of x is the slope of the line in slope-intercept form of the linear functions.

Thus ,

Slope = 1 / 5

And the correct answer is (( D )) .

Given that these triangles are similar, what is the perimeter of triangle PQR? Show your work.

dimaraw [331]

Answer:

Step-by-step explanation:

I use the Pythagoras theorem.

$\sqrt{a^{2} +b^{2} } =c^{2}$

$4^{2}{x}6^{2} = c^{2}$

16 x 36= 576

$\sqrt{576} = 24$

A random sample of 40 binomial trials resulted in 14 successes. test the claim that the population proportion of successes does

mylen [45]

Using the z-distribution, since the p-value of the test is of 0.057 > 0.05, there is not enough evidence that the population proportion of successes does not equal 0.50.

<h3>What are the hypotheses tested?</h3>

At the null hypotheses, we test if the proportion of successes equals 0.5, hence:

$H_0: p = 0.5$

At the alternative hypotheses, we test if it does not equal, hence:

$H_1: p \neq 0.5$

<h3>What is the test statistic?</h3>

The test statistic is given by:

$z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}$

In which:

$\overline{p}$ is the sample proportion.

p is the proportion tested at the null hypothesis.

n is the sample size.

For this problem, the parameters are given by:

$n = 40, \overline{p} = \frac{14}{40} = 0.35, p = 0.5$

Hence the test statistic is given by:

$z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}$

z = (0.35 - 0.5)/(0.5/sqrt(40))

z = -1.9.

<h3>What is the decision?</h3>

Using a z-distribution calculator, considering a two-tailed test, as we are testing if the proportion is different of a value, with z = -1.9, we get that the p-value of the test is of 0.057.

Since the p-value of the test is of 0.057 > 0.05, there is not enough evidence that the population proportion of successes does not equal 0.50.
