Answer:
1/2 person
Step-by-step explanation:
We can use a ratio to solve
6 rolls 1 roll
------------ = -------------
3 people x people
Using cross products
6x =3
Divide each side by 6
6x/6 = 3/6
x = 1/2
1 roll will solve 1/2 person

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.
