Would need the net to answer. but to find the answer you need to find the slant height of the square pyramid, the slant height is the hypotenuse of the right triangle formed by the height and half the base length. Use the pythagorean Theorem
2.57 is the anwser. it comes out to be 2.56666667 which woukd round up to 2.57
The standard deviation is the square root of the variance...so that means the variance is the standard deviation squared.

For A well I can't do a graph ,but to do it you would start at 50 going up 25 each week
For B it would be 300 because 25×10=250 plus the 50 from his grandmother he would have 300
