Using the normal distribution, it is found that Sue will get a letter grade of B.
In a <em>normal distribution </em>with mean 
and standard deviation 
, the z-score of a measure X is given by:
- It measures how many standard deviations the measure is from the mean.
- After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.
In this problem, Sue got a grade of 0.85, hence 
.
- Looking at the z-table, z = 0.85 has a p-value of 0.8023, hence she is approximately in the top 20%, which is below the top 15% but above the top 50%, hence she got a letter grade of B.

A. Is not linear because is has no y
How this helped ya out! :D
Answer:
B, C, F
Step-by-step explanation:
3/4 is 3 times 1/4, so the number of walls Dan can paint is 3 times the number of cans Dan uses.
A. 1/2 can will paint 3/2 walls, not 2.
B. 1 can will paint 3 walls — true
C. 5/3 cans will paint 5 walls — true
D. 2 cans will paint 6 walls, not 8.
E. 5/2 cans will paint 15/2 = 7 1/2 walls, not 10.
F. 11/3 cans will paint 11 walls — true
Answer:
(a) 2996 units
(b) 1897 units
Step-by-step explanation:
p = 10,000(1 - 3/3 + e^-0.001x)
(a) p = $500
500 = 10,000(1 - 1 + e^-0.001x)
500/10,000 = e^-0.001x
e^-0.001x = 0.05
-0.001x = In 0.05 = -2.996
x = -2.996/-0.001 = 2996 units
(b) p = $1500
1500 = 10,000(1 - 3/3 + e^-0.001x)
1500/10,000 = (1 - 1 + e^-0.001x)
0.15 = e^-0.001x
-0.001x = In 0.15 = -1.897
x = -1.897/-0.001 = 1897 units
