Answer:
7 units
Step-by-step explanation:
Given
Required
The units that minimize the average cost
Differentiate
Equate to 0 to solve for x
Collect like terms
Divide by 98
Rewrite as:
Take square roots of both sides
Take multiplicative inverse of both sides
Only positive value will produce critical value. Hence, 7 units will produce the minimum average cost
76.343, 76.342, 76.332, 76.232
Answer:
7 percent
Step-by-step explanation:
We have the following information from the question:
The probability that a student chooses art as an elective is 15 percent:
The probability that a student chooses art or drama is 20 percent:
The probability that a student chooses both art and drama is 2 percent:
Recall that:
We plug in the various probabilities to get:
Hence the probability that a student chooses drama as an elective is 7 percent
