zaharov [31]

Answer:

R = 59x

Step-by-step explanation:

We are given the following in the question:

Cost per unit = $59

Let x units of product be sold.

We have to write an expression the amount of money received (revenue R) from the sale of x units of the product.

Revenue:

  • It is the total income  and is obtained by multiplying the quantity of goods sold by the unit price of the goods.

Revenue =

\text{Unit Cost}\times \text{Units sold}\\R = 59x

is the required expression of revenue.

HW 5.2
Marizza181 [45]

Answer:

The probability of no correct answers is 0.125 = 12.5%.

Step-by-step explanation:

For each question, there are only two possible outcomes. Either it is answered correctly, or it is not. The probability of a question being answered correctly is independent of any other question, which means that we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

In which C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

And p is the probability of X happening.

3 trials, each with probability of success (correct) given by p=0.50.

This means that n = 3, p = 0.5

The probability of no correct answers is

This is P(X = 0).

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

P(X = 0) = C_{3,0}.(0.5)^{0}.(0.5)^{3} = 0.125

The probability of no correct answers is 0.125 = 12.5%.
