A basketball player averages 22.5 points scored per game with a standard deviation of 6.2 points. In one game, the number of points the athlete scored was 1.2 standard deviations below his mean. How many points below average was this value?

15.06

Step-by-step explanation:

Average points per game (mean) (m) = 22.5

Standard deviation (sd) = 6.2

Number of point scored in a game is 1.2 standard deviations below the mean, how many points below average was the value

1.2 standard deviations = (1.2 * value of standard deviation) = (1.2 × 6.2) = 7.44

Hence, 1.2 standard deviations below the mean equals :

Mean - 7.44

22.5 - 7.44 = 15.06

Hence, score = 15.06

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
