I'm confused, I'm not sure if the 12 you added to the problem is like the number of the problem or part of the problem, but my answer is going to be with the 12 as part of the problem.

Answer:  19/4 or 4 3/4 or 4.75

Step-by-step explanation: First you have to use the PEMDAS, which means first you have to do the parenthesis first, so add the 1/4 to the 1/3 which equals 7/12. so do that to the second power and then multiply the 12 and add the 2/3 which gets you 19/4

What is a graph?

In mathematics, a graph is a visual representation or diagram that shows facts or values in an ordered way.

The relationships between two or more items are frequently represented by the points on a graph.

Here, for instance, we can plot a graph showing the type and quantity of school supplies used by pupils in a class based on the data provided below. Each supply is first counted, and the data is then shown in a table with specific colors in a logical order.

Given equation is y=-5x+50

Where y represents the gift card balance after x number of days.

First find some points on the line.

Putting x = 5 in the given equation:

y = (- 5 × 5) + 50

y = -25+ 50

y = 25

Putting x = 0 in the given equation:

y = (- 5 × 0) + 50

y = -0+ 50

y = 50

Putting x = -1 in the given equation:

y = (- 5 × (-1)) + 50

y = 5+ 50

y = 55

The points on the line are (5, 25), (0,50), and (-1,55).

Plot the points and join them.

Solving the system of equations 5x + 9y = 104x - 3y = 8 and  using elimination, x is 2 and y is 0.

The elimination approach involves taking one variable out of the system of linear equations by utilizing addition or subtraction together with multiplication or division of the variable coefficients. The addition property of equality is used in the elimination technique to solve systems of linear equations. The same value can be added to both sides of an equation. You can therefore add x + y to the left side of the first equation and add 8 to the right side of the equation if your system is x - 6 = 6 and x + y = 8.

Given,

Equation A: 5x + 9y = 10

Equation B: 4x - 3y = 8

Solving the system of equations using elimination,

Multiplying equation B by 3

5x + 9y = 10

12x - 9y = 24

---------------------

17x = 34

x = 2

Equating x = 2 in equation 2

4x - 8 = 3y

4(2) - 8 = 3y

The required sample size to estimate the true proportion of Illinois homes that have air conditioning to within 3% with 99% confidence is of:

1816.

The required sample size is obtained using the z-distribution, as we are working with a confidence interval of proportions.

The equation that determines the margin of error of a confidence interval is presented as follows:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which the variables used to calculated these bounds are listed as follows:

The confidence level is of 99%, hence the critical value z is the value of Z that has a p-value of [tex]\frac{1+0.99}{2} = 0.995[/tex], so the critical value is z = 2.575.

The estimate in this problem, along with the desired margin of error, are given as follows:

[tex]\pi = 0.56, M = 0.03[/tex]

Then the needed sample size is calculated as follows:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]0.03 = 2.575\sqrt{\frac{0.56(0.44)}{n}}[/tex]

[tex]0.03\sqrt{n} = 2.575\sqrt{0.56 \times 0.44}[/tex]

[tex]\sqrt{n} = \frac{2.575\sqrt{0.56 \times 0.44}}{0.03}[/tex]

[tex](\sqrt{n})^2 = \left(\frac{2.575\sqrt{0.56 \times 0.44}}{0.03}\right)^2[/tex]

n = 1816. (rounded up, as a sample size of 1815 would have a margin of error slightly above 3%).

the slope ( rise over run ) is 1/2

Answer:

When the slope of a line is changed to a value that is less than 1, the line becomes less steep. This means that the change in the y-value (the vertical direction) for a given change in the x-value (the horizontal direction) is smaller than it was before. For example, if the original line had a slope of 2 and the new slope is 0.5, the line will be less steep and the change in y for a given change in x will be smaller.

The new amount of sit - ups will be 200.

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

Given that;

Tyson does 80 sit-ups during his work out.

And, He wants to increase his sit-ups by 25%.

Now,

Since, Tyson does 80 sit-ups during his work out.

And, He wants to increase his sit-ups by 25%.

Hence, We get;

The new amount of sit-ups = 80 + 25% of 80

                                          = 80 + 25/100  × 80

                                          = 80 + 20

Step-by-step explanation:

To find a ratio of one item to another we divide the quantity of the first item to the second.

We know Ann has 3 cups of seeds, and overall 11 ingredients. So her ratio is 3/11. Or 3 cups of seeds for every 11 ingredients.

Answer:

3 : 11

Trail Mix Recipe:

Total number of cups of all the ingredients:

⇒ 5 + 3 + 1 + 2 = 11

Therefore, the ratio of seeds to total ingredients is:

Note: The ratio cannot be reduced further since both 3 and 11 are prime numbers.

x = number of cards

the production costs (PC) per day are

PC(x) = 264 + 1.1x

the sales (S) are

S(x) = 5.1x

the profit (P) per day is sales minus costs

P(x) = S(x) - PC(x) = 5.1x - (264 + 1.1x) =

= 5.1x - 264 - 1.1x = 4x - 264

we need to find the value of x, so that P(x) = 52.

52 = 4x - 264

316 = 4x

x = 316/4 = 79

79 cards must be delivered daily to make a profit of $52.

x² - x - 4 = 0 is the equation that can be used to find the value of x.

Given,

The dimensions of a sand box is given as (x + 2) inches and (x + 1) inches.

The value of the area, in square inches, of the sandbox is equal to the value the perimeter in inches.

We have to find an equation that can be used to find the value of x;

Here,

Consider the sand box as a rectangle.

Area of rectangle = length x width

That is,

Area of sand box = (x + 2) (x + 1) = x² + x + 2x + 2 = x² + 3x + 2

Now, Perimeter of rectangle = 2(length + width)

That is,

Perimeter of sand box = 2(x + 2 + x + 1) = 2(2x + 3) = 4x + 6

Now,

Equate both the equations;

x² + 3x + 2 =  4x + 6

x² + 3x + 2 - 4x - 6 = 0

x² - x - 4 = 0

Therefore,

The equation that can be used to find the value of x is x² - x - 4 = 0

The line is the best fit because the sum of the residuals is a small number(1.2), so option D is correct.

A straight line that minimizes the gap between it and some data is called a line of best fit. In a scatter plot containing various data points, a relationship is expressed using the line of best fit.

Calculate the residual as shown below,

[tex]Residual = y - \hat{y}[/tex]

12 - 9.1 = 2.9

9 - 11.9 = -2.9

16 - 13.3 = 2.7

14 - 14 = 0

5 - 15.4 = -10.4

24 - 17.5 = 6.5.

Hence, the sum of the residuals is given as follows:

2.9 - 2.9 + 2.7 + 0 - 10.4 + 6.5 = 1.2

The sum of the residual is a small number, so it is the best fit.

By logarithm properties, the logarithmic equation 2 · ㏒ₐ (5 · x³) - (1 / 2) · ㏒ₐ (2 · x + 3) is equivalent to ㏒ₐ [(25 · x⁶) / √(2 · x + 3)]. (Correct choice: A)

In this problems we have a logarithmic equation that must be simplified by means of logarithm properties, all of them described below:

Logarithm of a product of two numbers

㏒ₙ (a · b) = ㏒ₙ a + ㏒ₙ b

Logarithm of a division of two numbers

㏒ₙ (a / b) = ㏒ₙ a - ㏒ₙ b

Logarithm of a power of a number

㏒ₙ aˣ = x · ㏒ₙ a

Now we proceed to reduce the logarithmic equation into a single expression:

2 · ㏒ₐ (5 · x³) - (1 / 2) · ㏒ₐ (2 · x + 3)

㏒ₐ (5 · x³)² - ㏒ₐ √(2 · x + 3)
