For quantity 50, the Z scores are ...
(50 -51.6)/1.3 ≈ -1.23 . . . . . . .company G
(50 -52.5)/1.8 ≈ -1.39 . . . . . . company H
Since the z-score from Company G is closer to zero than the z-score of Company H, the company that produced a package with 50 key rings in it is most likely Company G.
_____
The probability of exactly 50 key rings is higher the closer the z-score is to zero. The probability of at least 50 key rings is higher for lower z-scores. The way the problem's answer statement is worded, it appears the probability of interest is that of having exactly 50 key rings in the package.
A. 1.20c is the correct answer
The answer is 25, 33. The difference between each consecutive number is 8.
X will be equal to 36.
We would get this answer by dividing 24 by 6, which would equal 4.
The 4 means that the sides of the triangle are increased 4 times.
Then you would multiply 9 by 4.
