Answer:
$13.50
$750
Step-by-step explanation:
Using the normal distribution, it is found that the mean is of and the standard deviation is of .
<h3>Normal Probability Distribution</h3>
The z-score of a measure X of a normally distributed variable with mean and standard deviation is given by:
- The z-score measures how many standard deviations the measure is above or below the mean.
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
In this problem, we have that the p-value of Z when X = 30 is of 0.1, hence, when X = 30, Z = -1.28, so:
The p-value of Z when X = 32.5 is of 0.2, hence when X = 32.5, Z = -0.84, hence:
Hence:

Answer:
15x + 30
Step-by-step explanation:
Let x represent the number of weeks someone is a member. 30 is constant because it never changes.
Answer:
x=(p-n)/m
Step-by-step explanation:
Transfer M to the next side to be divided all what is after the equal sign.
To solve the equation undo the operations on the variable in reverse of PEMDAS
this eliminates "S" subtract 7 with "A" add 7
Simplified both sides
this eliminates "D" divide by 5 with "M" multiply by 5
ANSWER z = 30
