Jerry had an average score of 85 on his first 8 quizzes. He had an average score of 81 on his first nine quizzes. What score did he earn on his ninth quiz? side note: I got 49 the first time i tried it but when i checked it, it was wronfg

Answers

Well, let's calculate how many points in total he got so far!

He did 8 quizzes, on average 85 points: 85*8=680 points.

He scored a number of points in his ninth quiz, let's call this number "x".

If we want to calculate the average after the ninth quiz, we take the sum of points then (which is 680+x) and we divide it by 9:

(680+x)/9

we also know that this is equal to 81:

(680+x)/9=81

((680+x))/(9)=81

multiply both sides by 9:

(680+x)}=729

substracting 680 from both sides:

x=49

well, i got 49 too.

I really can't see where the mistake could be?

where did you check it? my best guess is that the place where you checked it had a typo...?

Adult male heights are normally distributed with a mean of 70 inches and a standard deviation of 3 inches. The average basketball player is 79 inches tall. Approximately what percent of the adult male population is taller than the average basketball player?0.13%
0.87%
49.87%
99.87%

Answers

Given:
average height of a basketball player = 79 inches
μ = 70 inches
σ = 3 inches

standardize x to z = (x - μ) / σ 
P(x > 79) = P( z > (79-70) / 3) 
= P(z > 3) = 0.0013
0.0013 x 100% = 0.13%



0.13 % of the adult male population is taller than the average basketball player.
