Answer:

x = 19

Step-by-step explanation:

To solve proportions, you first need to cross multiply. $\frac{19}{4}= \frac{x}{4}$ , you would need to multiply each top number by 4. 76 = 4x, which then could easily be simplified down to 19 by just dividing by four.

<h3>♫ - - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - ♫</h3>

➷ Standard deviation = $\sqrt{(n*p)(1 - p)}$

Substitute the values in:

$\sqrt{(500 *0.84)(1-0.84)}$ = 8.1975...

This can be rounded to give an approximate answer of 8.2

The answer is option A.
