Karina plays a video game that is scored by round. In about 500 rounds, her career average is 20 points per

round with a standard deviation of 5 points per round. Suppose we take random samples of 3 past rounds and

calculate the mean number of points ī that she scored in each sample.

Calculate the mean and standard deviation of the sampling distribution of 2.

You may round to one decimal place.

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2

hope this ! : )
