Answer:

x = 17

Step-by-step explanation:

Use the interior angle sum theorem which says:

if n is the number of sides the sum of the interior angles is 180(n-2)

there are 6 sides, so the interior angle sum is 180(6 - 2) = 180 * 4 = 720.

This means that if you add all the angles you will get 720, so:

$110 + 8x - 1+5x+36+116+7x+19+6x-2=720$

$26x+278=720\\26x = 442\\x = 17$

Stratified random sampling is a method of sampling that involves the division of a population into smaller groups known as strata. In stratified random sampling or stratification, the strata are formed based on members' shared attributes or characteristics. Stratified random sampling is also called proportional random sampling or quota random sampling.

By contrast, simple random sampling is a sample of individuals that exist in a population; the individuals are randomly selected from the population and placed into a sample. This method of randomly selecting individuals seeks to select a sample size that is an unbiased representation of the population. However, it's not advantageous when the samples of the population vary widely.

Can i please get help on this Question?

Hi there!

Given:
$4m + \frac{23 + n}{p - 3} \\ m = 7 \\ n = 2 \\ p = 8$

In order to evaluate the expression with the given values of m, n and p, we must substitute then into the expression. Then we use the correct order of operations (PEMDAS) to calculate.

Let's substitute first!
$4(7) + \frac{(23 + 2)}{(8 - 3)}$

Now find the numerator and denominator of the fraction.
$4(7) + \frac{25}{5}$

Next up: multiplying
$28 + \frac{25}{5}$

Divide the fraction.
$28 + 5$

And finally add the integers.
$33$

Hence, the answer is 33.
~ Hope this helps you!
