Answer:
The system is of equations is:

Where g is the amount of general tickets and r is the amount of reserve tickets.
35 general tickets and 25 reserve tickets were sold.
Step-by-step explanation:
Let general tickets be represented by g and reserved tickets be represented by r.
Each general ticket sells for $10 each and reserved tickets $15 each. Dave collected a total of $725. Thus:

And a total of 60 tickets were sold. Hence:

Our system of equations is:

We can solve by substitution. First, divide both sides of the first equation by 5:

Next, we can subtract a variable (r in this case) from the second equation:

Substitute:

Distribute:

Simplify:

Subtract:

Using the previous equation:

Substitute and evaluate:

So, 35 general tickets and 25 reserve tickets were sold.
Answer: 29.916 minutes
Step-by-step explanation:
Given the following :
Mean of distribution = 17.8 minutes
Standard deviation of distribution = 5.2 minutes
Percentage of customers to give free lube and oil change service should not exceed 1% if the customer waits beyond the guaranteed time ;
Length of guarantee :
Since % of customers should not exceed 1%
Then probability of not being chosen = (1 - 0.01) = 0.99
Using the z table to find the Zscore of 0.99,
Zscore of 0.99 = 2.33
This is 2.33 standard deviations above the mean
(2.33 × standard deviation) + mean value
(2.33 × 5.2 minutes) + 17.8 minutes
12.116 + 17.8
= 29.916 minutes
It is HE. Hope this helps!!!!! #Batgirl
