Answer: Ron's z-score is <u>+1.2</u>.
B. 1.2 standard deviation above the mean .
Step-by-step explanation:
Let X deontes the scores of the final exam
Given : Ms. Meyer's statistics class follow a normal distribution with Mean = 82
standard deviation =5.1
Formula : 
Ron scored 88 on the final.
So, put x=88

Ron's z-score is <u>+1.2</u>.
Also, 88= 86+(1.2 x 5.1) = Mean +1.2 x (standard deviation)
i.e. This means that Ron's final score is<u> 1.2 standard deviation above the mean </u>.
Answer:
Smoothie = 3
Ice cream = 1.5
Step-by-step explanation:
2s + i = 7.5
3s + 2i = 12
subtract the equations
(3s + 2i) - (2s + i) = s + i
s + i = 4.5
2s + i = 7.5, so s must equal 3 (7.5 - 4.5)
If s = 3, then i is 1.5 (4.5 - 3.5)
To check, plug 3 and 1.5 into s and i.
2(3) + 1.5 = 7.5
6 + 1.5 = 7.5
7.5 = 7.5
3(3) + 2(1.5) = 12
9 + 3 = 12
12 = 12
well, Marcus and Ben are both 5 feet tall and a little bit more, Marcus is 19/24 more and Ben is 9/16 more, so the 5's in the fraction are the same, so which one is larger, 19/24 or 9/16?
we can simply put both fractions with the same denominator, by <u>multiplying one by the other's denominator</u>, so let's proceed,
