Answer:

  2876 books

Step-by-step explanation:

If we let y1 and y2 represent the costs from method 1 and method 2, then we have, for x books published, ...

  y1 = 12841 +24.25x

  y2 = 48072 +12x

These costs will be equal when ...

  y1 = y2

  12841 +24.25x = 48072 +12x

  12.25x = 35231 . . . . . . . . . . . . . subtract 12841+12x

  x = 2876 . . . . . . . . . . divide by 12.25

The costs will be the same for production of 2876 books.

5x + 6y = 20 , 8x - 6y = -46

Answers

Answer:

5x + 6y = 20_____(1)

8x - 6y = -46_____(2)

Solving simultaneously:

Eqn(1) + Eqn(2)

5x + 8x + 6y + (-6y) = 20 + (-46)

13x = -26

x = -2

substituting this into Eqn (1):

5(-2) + 6y = 20

-10 + 6y = 20

6y = 30

y = 5

hence:

x = -2,y = 5.

dult men have heights with a mean of 69.0 inches and a standard deviation of 2.8 inches. Find the z-score of a man 73.4 inches tall. (to 2 decimal places)

Answers

Answer:

The z score is 1.57

Step-by-step explanation:

μ = 69.0, σ = 2.8 and x = 73.4

The objective of the problem is to obtain the z-score of a man 73.4 inches tall. The required z score is derived through the following formula "{x - μ / σ}"

z = 73.4 - 69.0 / 2.8

z = 4.4 / 2.8

z = 1.571428571428571

z = 1.57

Thus, the z score is 1.57.

a=-13, b=13
.
a = 13,b=-13
a = 13,- 13

Answers

Answer:

a = 13, b = 13

Step-by-step explanation:

In this example predicted value is 87 and actual value is 100

Error is 100 - 87 = 13

Absolute error is same, |100 - 87| = 13

So the correct choice is the last one:

a = 13, b = 13

The correct option is 'No Solution'.

Step-by-step explanation:

Given the system of the equations

[tex]y=\frac{1}{2}x-1[/tex]

[tex]2x-4y=12[/tex]

solving the system of the equations

[tex]\begin{bmatrix}y=\frac{1}{2}x-1\\ 2x-4y=12\end{bmatrix}[/tex]

[tex]\mathrm{Subsititute\:}y=\frac{1}{2}x-1[/tex]

[tex]\begin{bmatrix}2x-4\left(\frac{1}{2}x-1\right)=12\end{bmatrix}[/tex]

[tex]2x-4\left(\frac{1}{2}x-1\right)=12[/tex]

[tex]2x-2x+4=12[/tex]

[tex]4=12[/tex]

as

4=12 is false, therefore the system of equations has no solution.

Therefore, the correct option is 'No Solution'.

6. A music video website received 5.000
comments on a new song they released
The next day, the artist performed the song
on television and an additional 1500
comments were made on the website. What
was the percent of increase? ​

Answers

Answer:

30%

Step-by-step explanation:

To be able to calculate the percent of increase between two numbers, you have to divide the increase by the initial number and multiply by 100:

Increase= 1,500

Initial number=5,000

Percent of increase=(1,500/5,000)*100

Percent of increase=0.3*100

Percent of increase=30%

According to this, the answer is that the percent of increase was 30%.

A function that is injective but not surjective

An example of an injective function R→R that is not surjective is h(x)=ex. This "hits" all of the positive reals, but misses zero and all of the negative reals. But the key point is the the definitions of injective and surjective depend almost completely on the choice of range and domain.

Which of the following best represents a linear proportional relationship?

Answers

A linear proportional relationship is shown by y = 3x - 7.

What is a linear relationship?

We know that when we talk about a linear relationship, we mean the kind of relationship that would obey the equation of the straight line and the equation of the straight line would be y = mx + c

We have to look at the representations and see the one that actually fits into the model that have been shown above and when we look at it we can see that the y = 3x - 7.

This follows the pattern of the equation of the straight line.

The best representation of a linear proportional relationship is the table of values

How to determine the best linear proportional relationship?

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

The list of options

As a general rule, the equation of a linear proportional relationship is represented as

y = kx

Where k is the constant of proportion

This means that the given equations are not proportional relationship because they do not have the form y = kx

i.e. y = 3x - 7 and y = 8x + 25 do not have the form y = kx

Also, the equation y = kx implies that the graph passes through the origin

So, the given graph is not

The equation of the table is represented as

y = Y/X * x

So, we have

y = 2/24 * x

This gives

y = x/12

The equation of the table is of the form y = kx

Hence, the solution is the table of values
