Therefore at $5 you selling 15 mugs will generate the maximum revenue.

In discrete mathematics, a graph is made up of points called vertices, and the connecting lines between them are called edges. Simple graphs, linked and unconnected graphs, weighted graphs, bipartite graphs, directed and undirected graphs, and linked and unconnected graphs are only a few of the numerous varieties of graphs.

Here,

For $0 for , 50 mugs be sold

For $10 for , 0 mugs be sold

Thus, from graph

1)  Slope= 50/-10 =-5

2) m(p)= -5(p-10) =-5p +10

=> m(p) =10 -5p

3)Revenue R(p) = m(p)

R(p) = 10 -5p

4) point(5,15)

5) at price p =0 , p=5 , we do not make any money

6)At $5 most revenue is made

7)when p=5

R(p) = 10 -5(5)

R(p) = 15

Thus , 15 coffee mugs will yield max revenue

8)Max revenue = $45

The required compatible number of the given two number are 500 and 200 and sum is 700.

In math, compatible numbers are the numbers that are not difficult to add, deduct, duplicate, or gap intellectually. compatible number  are close in worth to the real numbers that make assessing the response and figuring issues more straightforward. We can adjust the numbers to the closest ten, hundred, thousand or 10,000 to make them viable numbers. For example, in the event that we need to add 493 and 549, we can make the numbers viable by gathering them together to the closest tens or hundreds. 490 and 550 (adjusted to the closest tens) or 500 and 500 (adjusted to the closest hundreds) are a lot simpler to settle.

So, the compatible number of 455 is 500 and that of 225 is 200.

Compatible sum = 500 + 200 = 700.

Answer:

2 : 18

Step-by-step explanation:

to find equivalent ratios , multiply or divide each part of the ratio by the same numeric value.

1 : 9 ( multiply both parts by 2 )

= 2 : 18

or

1 : 9 ( multiply both parts by 3 )

= 3 : 27

and so on...

The solution of the expression is ( 4 + √3 / x) ( 4 + √13 / x).

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

The given expression is 4 + √(3x⁻²) and 4 + √(13⁻²). The expression will be solved as,

E = {[4 + √(3x⁻²)]} { {4 + √(13x⁻²).]}

E =  {4 + [√3 / √x²]  { [4 + √13 / √x²]}

E = ( 4 + √3 / x) ( 4 + √13 / x).

The correct characterization of the limit distribution and other Questions are answered in the following steps.

For the first question, the distribution of (An-a) is approximated best by N(0, n) because the variance of the sample mean of i.i.d. standard normal variables is 1/n.

For the second question, since An converges in probability to a constant, Bn = 4An also converges in probability to 4a. Therefore, the sequence of random variables (Bn-b) does converge in distribution.

For the third question, the limit distribution of (Bn-b) is N(0, 4^2 * n) because the variance of the product of a random variable and a constant is the constant squared times the variance of the random variable.

Step-by-step explanation:

The affect of mean and median due to the birth of the 4th kitchen is B. Both the mean and median will increase, but the mean will increase by more than the median.

The median is the middle value when the values are ordered from smallest to largest. In this case, the median of the first 3 kittens is 153 because it is the middle value of (147, 153, 159). The median of all 4 kittens is 153 because it is the middle value of (57, 147, 153, 159). The median does not change because the addition of the 4th kitten does not change the position of the middle value.

The mean is calculated by adding up all the values and dividing by the number of values. In this case, the mean of the first 3 kittens is:

(147 + 153 + 159) / 3 = 153

The mean of all 4 kittens is:

(147 + 153 + 159 + 57) / 4 = 128

The mean increases because the addition of the 4th kitten with a lower mass pulls the overall average down.

After solving the equation, the number of hours obtained is that after 2 hours, the cost ends up being the same for either artist.

Mathematical expressions with two algebraic symbols on either side of the equal (=) sign are called equations.

This relationship is illustrated by the left and right expressions being equal. The left-hand side equals the right-hand side is a basic, straightforward equation.

As per the given information in the question,

Booking fee of Martha = $10

Additional hourly charge of Martha = $40

Then, the equation will be,

y = $10 + $40x            (i)

Here, y is the total cost and x is the number of hours.

Booking fee of Jackie = $20

Additional hourly charge of Jackie = $35

Then, the equation for this will be,

y = $20 + $35x           (ii)

Here, y is the total cost and x is the number of hours.

Then, depending on the length of the show, the cost could end up being the same for either artist.

So,

From equations (i) and (ii)

$20 + $35x =  $10 + $40x  

20 - 10 = 40x - 35x

Hourly rate = $35/7 hours

Using the above as a guide, we have the following:

Evaluate the quotients

Hourly rate = $5 per hour

The number of hours Jessica will have to babysit is calculated as

Number of hours = 160/Hourly rate

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

Number of hours = 160/5

Answer:

  17.86

Step-by-step explanation:

You want to find y when x=8 using the equation y = 13.06 +0.6x.

Put the value of the variable in place of the variable in the equation, and do the arithmetic.

  y = 13.06 +0.6x

  y = 13.06 +0.6·8 . . . for x=8

  y = 13.06 +4.8

  y = 17.86

The estimated value of y for x=8 is 17.86.

Step-by-step explanation:

To solve an equation for a variable, you can isolate the variable by performing operations that eliminate all other terms.

In this case, the given equation is 2x^2/y = w + 2/4. To solve for w, you can first eliminate the 2/4 term on the right-hand side by multiplying both sides of the equation by 4/2:

4 * (2x^2/y) = 4 * (w + 2/4)

4 * 2x^2/y = 4w + 4 * 2/4

8x^2/y = 4w + 2

Then, you can subtract 2 from both sides to eliminate the 2 on the right-hand side:

8x^2/y - 2 = 4w + 2 - 2

8x^2/y - 2 = 4w

Finally, you can divide both sides of the equation by 4 to eliminate the 4 on the right-hand side:

(8x^2/y - 2) / 4 = (4w) / 4

w = 8x^2/7 - 2

Therefore, the correct answer is w = 8 x squared minus 2 y Over y. This is an equivalent equation to find w, as it gives the same value for w as the original equation when the same values are used for x and y.

The other equations given are not equivalent to the original equation for finding w.
