1/4 × 4800 = $1200 (Mariam)
3/5 × 4800 = $2880 (Anna)
4800 - 1200 - 2880 = $720
Sara received 720 dollars
Answer:
36π in^2
Step-by-step explanation:
Area of a circle = π(6)^2 = 36π
To compute the mean, you simply have to sum all the elments in the data set and the divide the sum by the number of elements:

To compute the variance, we first need to compute the distance of each element from the mean. To do so, we build a "parallel" dataset, given by the difference of every value and the mean:


Now we need those difference squared:

The variance is the mean of this new vector, so

Finally, the standard deviation is simply the square root of the variance, so you have

c is 0 on the right and -1 on the left Hope this helps.
