The typical average price of gasoline should be $2.81 and not $2.69 because $2.69 is not the average of the sampled prices.
<h3>What is the mean of the sample?</h3>
We are given the prices of a gallon of gasoline from 5 gas stations surveyed as; $2.79, $2.99, $2.69, $2.89, and $2.69.
Thus, to calculate the mean, we will use the formula;
Mean = ∑x/n
Mean = (2.79 + 2.99 + 2.69 + 2.89 + 2.69)/5
Mean = 14.05/5
Mean = $2.81
Thus, the typical average price of gasoline should be $2.81 and not $2.69

Answer:
a)Average cost function =
Marginal cost function =
b)
c) is the average cost to produce first 2000 items
C'(2000)=0.1 is the marginal cost to produce 2001 th item
Step-by-step explanation:
Cost function:
a)Find the average cost and marginal cost functions.
Average cost function =
Average cost function =
Marginal cost function =
b) Determine the average and marginal cost when x = a.
a = 2000
Average cost function =
So,
Marginal cost function =
c)Interpret the values obtained in part (b).
is the average cost to produce first 2000 items
C'(2000)=0.1 is the marginal cost to produce 2001 th item
Answer:
20 stacks of 5 pennies weight 0.33 pounds
Step-by-step explanation:
<u>First, we need to calculate the weight in kilograms of 20 stacks of 5 pennies:</u>
20 stacks= 0.0075*20
20 stacks= 0.15 kg
<u>Now, we can determine the weight in pounds:</u>
1kg = 2.2 pounds
0.15kg = ?
Weight in pounds= (0.15*2.2)/1
Weight in pounds= 0.33 pounds
20 stacks of 5 pennies weight 0.33 pounds
