Its max is 780
2/3 + 1/6 = 5/6
650/5=130
650+130=780
I believe the answer is 142.09
4^3
the value would be
64
Answer:
c. the biology test
Step-by-step explanation:
To answer this problem we need to calculate the z-score of both tests, using the formula:
z = (x - μ) / σ
Where x is Sue's score, μ is the mean, and σ is the standard deviation.
- For the <u>biology test</u>, the z-score is:
z = (76 - 70) / 7 = 6/7 = 0.857
- For the <u>math test</u>, the z-score is:
z = (76 - 75) / 10 = 1/10 = 0.100
Because the z-score for the biology test is greater than the z-score for the math test, Sue did better in the biology test, in comparison to the rest of the class.
6/8 is equivalent to 3/4, and 3/4=.75, and .75/100=75 percent. So yes, it is.
