Find the standard deviation for the given sample data. Round your answer to one more decimal place than is present in the origin

Tema [17]

Answer:

s = 19.7

Step-by-step explanation:

First we need to calculate the mean x' of the sample as:

$x'=\frac{55+18+39+20+20+44+69}{7}=37.9$

We sum all the scores and divide them by the number of scores.

Then, the standard deviation s is calculated as:

$s=\sqrt{\frac{(55-37.9)^2+(18-37.9)^2+(39-37.9)^2+(20-37.9)^2+(20-37.9)^2+(44-37.9)^2+(69-37.9)^2}{7-1} }\\ s=19.7$

We square every score less the mean, sum every value, then divide that by the number of scores less 1 and finally, we calculate the square root.

So, the standard deviation of the sample is 19.7

What is the answer to 8x-9=12+11x

mrs_skeptik [129]

Answer:

x = -7

Step-by-step explanation:

8x - 9 = 12 + 11x

Subtract 11x to both sides of the equation. Then, it will look like this:

-3x - 9 = 12

Add 9 to both sides of the equation. After that, it will look like this:

-3x = 21

Divide both sides of the eqution by -3. Your answer is:

x = -7
