I need help with this question and an explanation " A company manufactures electrical components. The cost, $C (including rent, materials and labour), is given by the rule C = n + 3000, and its revenue, $R, is given by the rule R = 5n, where n is the number of components produced."

a. Sketch the graphs C and R on the same set of axes and determine the point of intersection.

b. State the number of components n where the costs SC are equal to the revenue $R

c. Fewer than 6

Step-by-step explanation:

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:

The standard deviation of the binomial distribution is:

In the binomial distribution, an outcome is considered unusual if it is more than 2.5 standard deviations below the mean.

Seventy-nine percent of products come off the line ready to ship to distributors.

This means that

Your quality control department selects 12 products randomly from the line each hour.

This means that

Mean:

Standard deviation:

Unusual:

So fewer than 6 is considered unusual.
