Morty buys and sells computer parts

mart [117]

Answer:

1. Morty's total cost for the items he purchased was $210

2. Morty's revenue from the sale of the items was $547

3. Morty's Total profit was $337

Explanation:

The complete question is:

Morty buys and sells computer parts. He bought two monitors for $25 each and later sold them for $88 each. He bought four cases for $15 each and later sold them for $24 each. He bought five memory modules for $20 each and later sold them for $55 each.

Morty's total cost for the items he purchased was

Morty's revenue from the sale of the items was

Morty's Total profit was

<h2>Solution</h2>

1. Morty's total cost for the items he purchased was

Build a table with the number of parts and their costs:

Component Amout Unit cost Total cost

$ $

Monitors 2 25 50

Cases 4 15 60

Memory 5 20 100

Total cost = $50 + $60 + $100 = $210

2. Morty's revenue from the sale of the items was

Build a table with the number of parts and their selling prices:

Component Amout Unit price Total cost

$ $

Monitors 2 88 176

Cases 4 24 96

Memory 5 55 275

Total revenue: $176 + $96 + $275 = $547

3. Morty's Total profit was 

The total profit is the total revenue less the total cost: $547 - $210 = $337.

Answer:

15.87% probability that 48 or more from this sample were insured by the FHA

Step-by-step explanation:

I am going to use the normal approximation to the binomial to solve this question.

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

Can be approximated to a normal distribution, using the expected value and the standard deviation.

The expected value of the binomial distribution is:

$E(X) = np$

The standard deviation of the binomial distribution is:

$\sqrt{V(X)} = \sqrt{np(1-p)}$

Normal probability distribution

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

When we are approximating a binomial distribution to a normal one, we have that $\mu = E(X)$ , $\sigma = \sqrt{V(X)}$ .
