Last week Sarah had exams in math and in Spanish. On the math exam, the mean was µ = 40 with σ = 5, and Sarah had a score of X = 45. On the Spanish exam, the mean was µ = 60 with σ = 8, and Sarah had a score of X = 68. For which class should Sara expect the better grade?

The grades should be the same because the two z scores are same

Step-by-step explanation:

We are given the following information in the question:

Math

Mean, μ = 40

Standard Deviation, σ = 5

Math's score = 45

Formula:

Putting values, we get

Spanish

Mean, μ = 60

Standard Deviation, σ = 8

Spanish's score = 68

Formula:

Putting values, we get

Thus, both have the same z-score, we can say that, the grades should be the same because the two scores are in the same location and have the same z-score.

2 over 5

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.
