Variance is the average of the square of the differences of each data with the mean. To calculate for the variance, we first calculate for the mean. Then, we subtract each data with the mean. Next, each difference would be squared and added. The resulting value would be divided on how many data are used. We calculate as follows:
Mean = <span>9 + 7 + 6.5 </span>+ 7.5 + 7 + 8 + 5 + 6 + 7.5 + 8 / 10
Mean = 6.4
Squared of the sum of the differences = (9-6.4)^2 + (7-6.4)^2 + (6.5-6.4)^2 + (7.5-6.4)^2 + (7-6.4)^2 + (8-6.4)^2 + (5-6.4)^2 + (6-6.4)^2 + (7.5-6.4)^2 + (8-6.4)^2 = 17.15
Variance = 17.15 / 10 = 1.715
Answer:.3
Step-by-step explanation: 20/6 =.1
Hello,
Alicia borrowed $15,000
At 8% for 6 years
To get the % for 1 year
First multiply 15,000 by 8% (On a calculator would be easier)
You get 1,200
Now since she borrowed the money for 6 years, multiply 1,200 and 6
You get $7,200
So now, you add the $15,000 and $7,200
So Alicia has to pay $22,200 at the end of 6 years
Hope this helps

The fraction is equivalent to 1/2 since you can simplify 4/8 as (4/4)/(8/4) = 1/2.
