Answer and Step-by-step explanation:
Hello!
To calculate variance, we start by calculating the mean, or average of your question. Then, we subtract the mean from each data point, and square the differences. Next, we add up all the squared differences. Now, the last step is to divide The sum by n minus 1, where n equals the total number of data points from your question!
Hope this helps you!

Hello there!
First add 1.19 + .89 = 2.08
Then, subtract 2.08 from 55 = 55 - 2.08 = <span>52.92</span><span>

Roy is correct. When you multiply fractions, you multiply the numerator of one fraction and the other numerator of the other fraction, and vice versa for denominator.
7 x 3 = 21 (Numerators)
——- —-
3 x 8 = 32 (Denominators)
I hope this helped!
<span>-14 x 8 x 1/4 + (-22)
Apply BODMAS
Open the brackets:
</span>-14 x 8 x 1/4 + (-22) = <span>-14 x 8 x 1/4 -22
Division
-14 x 8 x (1/4) - 22 = </span><span>-14 x 8 x 0.25 - 22
</span><span>
Multiplication
</span><span>(-14 x 8 x 0.25 )- 22 = -28 - 22
</span><span>
Subtraction
-28-22 = -50
