Answer:
The answer is below
Explanation:
A What is the probability that all 4 selected workers will be the day shift?
B What is the probability that all 4 selected workers will be the same shift?
C What is the probability that at least two different shifts will be represented among the selected workers.
A)
The total number of workers = 10 + 8 + 6 = 24
The probability that all 4 selected workers will be the day shift is given as:


B) The probability that all 4 selected workers will be the same shift (
) = probability that all 4 selected workers will be the day shift + probability that all 4 selected workers will be the swing shift + probability that all 4 selected workers will be the graveyard shift.
Hence:

C) The probability that at least two different shifts will be represented among the selected workers (
)= 1 - the probability that all 4 selected workers will be the same shift(
)

Answer:
Contribution margin per unit: $42.9
Total contribution margin: $8,580
Explanation:
The contribution margin per unit is calculated by calculating the total contribution margin, which is basically the total sales, minus the costs of production, in this cae we have that we sold:
60 regular chairs
140 executive charis
Now the total in sales is:
Regular sales: $6,000
Executive chairs: $23,800
The variable cost of each is:
Regular chairs: $3720
Executive chairs: $17,500
We add up the sales and withdraw from it the total variable cost:
29,800-21,220=8,850
The total contribution margin is equal to $8850.
And the contribution margin per unit is given by dividing the total contribution margin by the number of units sold:
8850/200= 42.9
So the contribution margin per unit is 42.9 dollars.
Answer a. Estimate a population proportion.
Explanation:
A population proportion denotes a specific attribute of a population measured in percentage, the above analysis is on losing weight by the populace.
A mean only refers to the average of the population without reference to a particular quality.
The analysis is not testing a claim but it's only making reference to earlier findings on the population. A claim would have given us a specific quality which the population has been predicted or established to adhere to.
Answer:D.$14,100 gain
Explanation:
The par value of a bond is $100 when it's issued below the price it's issued at a discount which is a loss to the firm and when it's issued above the par value, it's issued at a premium which is a gain.
The issue of $705,000 means 7050 numbers were issued and retiring it $102 means at a premium of $2 per bond and a total of N14,100 gain.
