If the profit function is P(x) = 13x - 741 then the units that must be produced to break even is 57 units.

What is a profit function?

The difference between income and costs is referred to as profit. A relationship that depicts the difference created by subtracting the cost function from the revenue function is called a profit function. The ideal pairing of revenues and expenses to generate the greatest possible profit can be seen on the graph of a profit function.

Here, we have

Given

R(x) = 16x (The revenue function)

C(x) = 3x + 741 (The cost function)

Profit = Revenue - Cost

P(x) = 16x - 3x - 741

P(x) = 13x - 741

Hence, the profit function P(x) is  13x - 741.

For the company to break even, R(x) = C(x)

16x = 3x + 741

13x = 741

x = 57

Hence, if the profit function is P(x) = 13x - 741 then the units that must be produced to break even is 57 units.

a Markov chain is the probability defined by the below transition matrix. [ 1/3 2/3 1/5 4/5] has the steady state C. (10/13 3/13]

The steady state of a Markov chain is the probability distribution of possible states of the system. In this case, the steady state from the transition matrix ( Matrix can also be used to represent relationships between different variables.It is commonly used in mathematics, science and engineering to represent a variety of data. ) can be found by solving the system of equations:

P(X0) = P(X0) * 1/3 + P(X1) * 2/3

P(X1) = P(X0) * 1/5 + P(X1) * 4/5

Solving this system of equations yields the steady state of (10/13, 3/13).

Step-by-step explanation:

Answer:

a) 10

Step-by-step explanation:

Given information,

→ [3(x + 4)(x + 1)]/[(x + 2)(x - 2)]

→ x = 4

Let's evaluate the expression,

→ [3(x + 4)(x + 1)]/[(x + 2)(x - 2)]

→ [3(4 + 4)(4 + 1)]/[(4 + 2)(4 - 2)]

→ [(3 × 8)(5)]/(6 × 2)

→ (24 × 5)/12

→ 120/12 = 10

Therefore, the answer is 10.

The height needed to reach the desired volume is 5 feet

From the question, we have the following parameters that can be used in our computation:

Length = 8 feet

Volume = 240 cubic feet

Width = 6 feet

The height is calculated as

Height = Volume/(Length x Width)

Substitute the known values in the above equation, so, we have the following representation

Height = 240/(8 x 6)

Evaluate

Height = 5

Here, we have

Length = 28 cm

Volume = 6142.5 cubic cm

Height = 16.25 cm

The width is calculated as

Width = Volume/(Length x Height)

Substitute the known values in the above equation, so, we have the following representation

Width = 6142.5/(28 x 16.25)

Evaluate

Width = 13.5

Here, we have

Volume = 26214 cubic m

Height = 17 cm

The base area is calculated as

Base area = Volume/Height

Substitute the known values in the above equation, so, we have the following representation

Base area = 26214/17

Evaluate

Base area = 1542

Hence, the base area is 1542 square m

Answer:

The standard deviation is a measure of how much the values of a random variable tend to vary from the mean of the variable. In this case, the standard deviation of the random variable W is 3.5, which means that the values of W typically vary from the mean of 4 by about 3.5 attempted experiments. Therefore, the best interpretation of the standard deviation, in this case, is that values of W typically vary from 4 by about 3.5 attempted experiments, on average.

The value of x that will make the two given solids similar is: d. x = 31.

If two solids are said to be similar to each other, it means that one is a scale copy of the other, and one is enlarged by a scale factor to get the dimension of the other.

Thus, the corresponding linear dimensions of two similar solids are proportional or they have equal ratio.

Based on this definition, the equation below would be created to find the value of x that would make both solids similar to each other.

29/14.5 = x/15.5

Cross multiply:

Answer:

In this problem, the temperature of the hot liquid (T) is being modeled as a function of the number of minutes (n) that it has been in the refrigerator. The model is a linear function, which means that the temperature will change at a constant rate as the number of minutes increases.

The parameter -8 represents the rate at which the temperature is changing. Specifically, it represents the amount by which the temperature decreases in degrees Fahrenheit for every one minute that passes. For example, if the hot liquid has been in the refrigerator for 10 minutes, its temperature will have decreased by (-8 * 10) = -80 degrees Fahrenheit.

The parameter 175 represents the initial temperature of the hot liquid when it was first placed in the refrigerator. This is the temperature at n = 0, or when no time has passed.

So in the context of this problem, the parameters -8 and 175 represent the rate at which the temperature changes and the initial temperature of the hot liquid, respectively.

y = 3x + 5 is a linear relationship with a slope of 3.

A straight line is formed on the graph by the equation y=2x+1, which is a linear equation. The value of y eventually rises by twice the value of x + 1. This happens when the value of x grows.

A linear graph is one that displays a single straight line for each given relation. A straight line is what the word "linear" denotes. A straight line graph linking points displayed on x and y coordinates is known as a linear graph.

A linear non - proportional relationship could be written with as a slope - intercept with a non - zero intercept value. One such relationship with a slope of 3 can be expressed thus :

y = 3x + 5

Here, the linear relationship, has a slope value of 3 and an intercept value of 5. The function cannot be proportional due to the presence of a non-zero constant

Hence, Using a graphing calculator, the sketch of the linear relationship is attached.

m and n are integers such that mn is even, but m and n are both odd. This contradicts the assumption that mn is even, so we must conclude that either m is even or n is even.

Proof:

Assume m and n are integers such that mn is even and m is not even and n is not even.

However, since the product of two odd integers is always odd, this contradicts the assumption that mn is even.

Therefore, it must be true that m is even or n is even.

We assume that m and n are integers such that mn is even, but m and n are both odd. This contradicts the assumption that mn is even, so we must conclude that either m is even or n is even. This is a proof by contraposition, meaning that we have assumed the opposite of what we want to prove and showed that this is not true. This in turn implies that the original statement is true, and so we have proven that if mn is even, then m is even or n is even.

To answer (b), we first need to calculate the z-score for 86.3 cm using the population mean of 85 cm and standard deviation of 14 cm. This gives us a z-score of 0.7. We can then use the normal distribution table to calculate the probability of a sample mean of at least 86.3 cm with a z-score of 0.7, which is 0.9982. To answer (c), we need to calculate the z-score for 86.3 cm using the population mean of 80 cm and standard deviation of 14 cm. This gives us a z-score of 1.5. We can then use the normal distribution table to calculate the probability of a sample mean of at least 86.3 cm with a z-score of 1.5, which is 0.9817.

Part (b):

Z-score = (86.3 - 85) / 14
