Rewrite the following equation in slope-intercept form. 8x + 13y = -9
Write your answer using integers, proper fractions, and improper fractions in simplest form.

Since Point A is an element of a direct variation, the other points that are elements of this direct variation include the following:

B. [-2, -8].

E. [2, 8].

In Mathematics, a direct variation is also referred to as direct proportion and it can be modeled by using the following mathematical expression or function:

y = kx

Where:

In direct proportion, the value of x represent an independent variable while the value of y represents the dependent variable. Therefore, an equation that models the situation is given by:

-4 = -k

k = 4

y = 4x

When x = 8, the equation y = 4x is given by:

y = 4(8) = 32.

When x = -2, the equation y = 4x is given by:

y = 4(-2) = -8 (True).

When x = 4, the equation y = -4x is given by:

y = 4(4) = 16.

When x = 2, the equation y = 4x is given by:

y = 4(2) = -8 (True).

If a ski resort charges $55 for renting a snowboard or skis and $11 per hour for a lift ticket. If julian spent a total of $121. The number of hours is 6.

Let's call the number of hours Julian spent at the ski resort "h".

We know that:

55 (the cost of the equipment rental) + 11h (the cost of the lift ticket) = 121 (the total amount Julian spent).

So we can subtract 55 from both sides to isolate the lift ticket cost:

11h = 121 - 55 = 66

Finally, we divide both sides by 11 to find the number of hours:

h = 66 / 11 = 6

Therefore, Julian was at the ski resort for 6 hours.

The money factor that will be used to calculate bob’s payment is C) 0.00333

Money Factor can be converted to Annual Percentage Rate (APR) and vice versa.

So the money factor can be solved:

APR = 2400 x Money Factor

Money Factor = APR / 2400

Money Factor = 8% / 2400 = 0.0033333

Basically, APR is short for Annual Percentage Rate, which means an annual percentage. APR is widely applied to the money you are going to borrow. Like when you apply for a motor vehicle loan, credit card, consumer loan, loan for education, or home ownership loan.

The elevation gain of Mount Everest is 15,028 feet, a very impressive feat considering it is the highest elevation gain of any mountain in the world.

The difference between the height at the base of Mount Everest, which is 14,000 feet and the summit, which is 29,028 feet is 15,028 feet. This is also known as the elevation gain. It can be calculated using the following formula:

Elevation Gain = Summit Height - Base Height

So in this case, Elevation Gain = 29,028 ft - 14,000 ft

Which gives us: Elevation Gain = 15,028 ft

The elevation gain of Mount Everest is 15,028 feet, a very impressive feat considering it is the highest elevation gain of any mountain in the world.

we shall evaluate the distance between each points as follows:

AB = √[(8-8)² + (9-2)²] = 7

BC = √[(3-8)² + (13-9)²] = 6.4

CD = √[(-3-3)² + (9-13)²] = 7.2

DE = √[(-3+3)² + (9-13)²] = 9

EA = √[(8+3)² + (2-0)²] = 11.2

DB = √[(8+3)² + (9-9)²] = 11

perimeter of the figure = AB + BC + CD + DE + EA.

perimeter of the figure = 7 + 6.4 + 7.2 + 9 + 11.2

perimeter of the figure = 40.8 units.

The figure is observed to be a trapezium ABDE and a triangle BCD. Triangle BCD have base length DB = 11 with height from C to DB equal to 4.

Trapezium ABDE have sides AB and DE parallel to each other, and height DB = 11.

In rare instances, the numerical value of the standard deviation might be 0. The standard deviation, defined as the square root of the variance, is a measure of the dispersion of a collection of data. A collection of data's variance is the average of the squared departures from the mean.

The standard deviation represents the average level of variation in your dataset. It informs you how far each number deviates from the mean on average. A high standard deviation implies that values are spread out from the mean, whereas a low standard deviation shows that values are close to the mean. The standard deviation quantifies the data's dispersion around the mean value. It is useful for comparing data sets that have the same mean but a different range. The mean of the following two numbers, for example, is the same: 15, 15, 15, 14, 16 and 2, 7, 14, 22, 30. The second, on the other hand, is plainly more dispersed.

Here,

When all of the data points in a collection are equal, the deviations from the mean are all 0, and so the variance is likewise zero. When the variance is zero, the square root of the variance (the standard deviation) is likewise zero. As a result, the standard deviation can only be 0 if all of the data points in the collection are equal.

In other words, the standard deviation is 0 when there is no fluctuation or dispersion in the data.

In a random sample of eighteen people, the mean time at lunch was 28.4 minutes.

Standard deviation of 8.2 minutes.  

A common method to calculate the confidence interval for the mean of a normal distribution is to use the Z-score. For a 85% confidence interval, the Z-score is 1.44. Therefore, the confidence interval can be calculated as:

The confidence interval formula in statistics is used to describe the amount of uncertainty associated with a sample estimate of a population parameter.

Where,

n= Number of terms

[tex]$\overline{\mathrm{x}}[/tex]= Sample Mean

[tex]$\sigma[/tex]=Standard Deviation

[tex]$z_{\alpha / 2}[/tex]= Value corresponding to a2 in z table

[tex]$t_{\alpha / 2}[/tex]= Value corresponding to a2 in t table

[tex]$\alpha[/tex]=(1 - Confidence Level /100)

So for the given data, the confidence interval would be:

=28.4 ± 1.44 * 8.2 / √18

=28.4 ± 1.44 * 8.2 / 4.24

=28.4 ± 3.39

An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Given that, a line passes through (1, 6) and (3, 2), we need to find the equation of the line,  

We know that, an equation of a line passing through two points (x₁, y₁) and (x₂, y₂) is given by,

(y-y₁) = (y₂-y₁) / (x₂-x₁) (x-x₁)

Here, (x₁, y₁) and (x₂, y₂) = (1, 6) and (3, 2),

Therefore,

(y₂-y₁) / (x₂-x₁) = 2-6 / 3-1 = -4/2 = -2

Setting the equation,

y-6 = -2(x-1)

y-6 = -2x+2
