Answer:

Step-by-step explanation:
Let X be the number of units produced, and P be the cost of production.
#Given that 
Cost of production can be calculated as:

#Mean of the total cost is calculated as;

Hence, the mean cost of production is $2,000
#Variance of the total cost is calculated as;

Hence, the variancecost of production is $3,600
Answer:
x=-2/3
Step-by-step explanation:
Y=3/100x
y= 3/100 (150)
y=4.5
150+4.5=154.50 total cost of CD player.
Therefore that is the answer. Please mark as brainliest and give a thanks.

Step-by-step explanation:
Answer:
Population standard deviation (σ) = 0.3 in
Step-by-step explanation:
Sample mean = 3.07 in
Sample standard deviation (s) = 0.21 in
Sample size (n) = 62 cups
Population standard deviation (σ) = ?
The point estimate for the population standard deviation is given by sample standard deviation divided by the square root of the sample size:
