Hi there! :)

Step-by-step explanation:

<h2><u>Lesson: Slope and slope-intercept form</u></h2>

SLOPE=\frac{Y_2-Y_1}{X_2-X_1}=\frac{RISE}{RUN}

\frac{2-(-4)}{3-1}=\frac{6}{2}=3

<u><em>Slope is 3</em></u>

<u><em>Final answer is 3.</em></u>

<u><em>*The answer must have a positive sign.*</em></u>

I hope this helps you!

Have a nice day! :)

Anuta_ua [19.1K]

Answer:

175

Step-by-step explanation:

The sample size n in<em> Simple Random Sampling</em> is given by

\bf n=\frac{z^2s^2}{e^2}

<em> where z = 1.96 is the z-score associated with a 95% confidence level ans s the standard deviation. </em>

Replacing values

\bf n=\frac{(1.96)^2(675)^2}{(100)^2}=175

So, there should be 175 chief executive officers in a sample if we want to estimate the population mean annual salary plus bonus with a margin of error of $100,000
