Suppose that a pure monopolist can sell 10 units of output at $5 per unit and 11 units at $4.80 per unit. For the monopolist to
ivolga24 [154]

The marginal revenue of this monopolist's 11th unit of output is; $2.80

<h3>How to find the Marginal Revenue?</h3>

Marginal revenue is defined as the amount that you gained after selling all your units at a certain price.

Revenue is different from profit, because profit has to incorporate the expenses incurred in order to produce the product. For total revenue, that would just represent the total sales of a firm or company. However, marginal revenue is the additional cost a consumer has to pay when he acquires an additional unit of the product. Thus, marginal revenue is the change of sales per unit product.

Formula for Marginal Revenue is;

Marginal Revenue = ΔRevenue/ΔNumber of units

Thus;

Marginal Revenue = [11($4.80) - 10($5)]/(11 - 10)

Marginal Revenue = $2.8 per unit

Which of the following is a good practice for protecting computing devices.
Kryger [21]

A good practice for protecting computing devices is to: ensure your antivirus and other software are kept up-to-date.

Computing can be defined as a process that typically involves the use of computer hardware and software to manage, process and transmit data in order to successfully complete a goal-oriented task.

In Computer science, some examples of a computing device include the following:

  • Keyboard
  • Central processing unit (CPU)
  • Monitor
  • Router

Generally, a good practice for protecting computing devices is to ensure your antivirus and other software are kept up-to-date. Thus, you shouldn't use an outdated software application on your computing devices.

Assume that thermometer readings are normally distributed with a mean of 100o F and a standard deviation of 0.15o F. a) Draw and
son4ous [18]

The parameters of the normal distribution of the thermometer readings are its mean and the standard deviation

The probability that a thermometer reading is between 99.86o F and 100.07o F is 0.5403

<h3>The sketch of the normal distribution of the thermometer</h3>

The given parameters are:

  • Mean, μ = 100
  • Standard deviation, σ = 0.15

Next, we draw the normal distribution using a graphing calculator.

See attachment for the sketch of the normal distribution of the thermometer

<h3>The probability that a thermometer reading is between 99.86o F and 100.07o F</h3>

This means that:

x = 99.86 and x = 100.07

The probability is calculated as:

P(99.86 < x < 100.07) = P(x > 99.86) - P(x < 100.07)

Using the attached graph, we have:

P(99.86 < x < 100.07) = 0.5403
