(WILL GIVE BRAINLIEST)​

Answer:

Following are the solution to this question:

Step-by-step explanation:

x was its full computer product revenue from March to December.  In january and february, the revenue towards products and services before x quantities for computer product revenues will happen between March to December is $2,500.  

Whenever x quantity is sold, then 0.05x quantity was sold for supplies and equipment.  

The sum of accessories to sell should be calculated, indeed, year-round.  

It helps us to split into two parts  

y = accessory sales in January and February + accessories sales in March and December  

Use item 2  

y = $2,500 + March to December accessories sale  

Now use sections 1 and 3  

y = $2,500 + 0.05x

The above equation rewriting gives  

y = 0.05x + $2,500 (a)  

This formula is compared with a standard y = mx+c interrupt slope  

We got a pitch of 0.05 and a pitch of $2,500.

Answer:

5/7 or 0.71 is the answer

a. Point-slope form is: y - y0 = m(x - x0). Plugging in our values, we get: y - 2 = -3(x - 11). Typically we can just leave it like this, but for the sake of simplifying it down to slope-intercept form, it would be y = -3x + 35.

b. y - 2 = -3((0) - 11)

y - 2 = 33

y = 35.

c. y = -3x + 35.

1. We can calculate the slope (m): m = 498.7

2. We have the equation of the trend line: y = 498.7x - 1009.75

3.  The forecasted sales for year 5 is approximately 1483.75.

4.  The forecasted sales for year 6 is approximately 1982.45.

To use the Linear Trend Equation for forecasting sales in year 5 and 6, we need to calculate the equation of the trend line first. The formula for a linear trend line is:

y = mx + b

Where:

y = dependent variable (sales)

x = independent variable (year)

m = slope of the line

b = y-intercept

To find the slope (m) and y-intercept (b), we can use the least squares method or the method of linear regression. However, since we only have four data points, we'll use a simplified version of the linear regression formula:

m = [(nΣxy) - (ΣxΣy)] / [(nΣx^2) - (Σx)^2]

b = (Σy - mΣx) / n

Let's calculate the values:

n = number of data points = 4

Σx = sum of years = 1 + 2 + 3 + 4 = 10

Σy = sum of sales = 230 + 235 + 239 + 243 = 947

Σxy = sum of (year * sales) = (1 * 230) + (2 * 235) + (3 * 239) + (4 * 243) = 4861

Σx^2 = sum of (year^2) = (1^2) + (2^2) + (3^2) + (4^2) = 30

Now we can calculate the slope (m):

m = [(nΣxy) - (ΣxΣy)] / [(nΣx^2) - (Σx)^2]

= [(4 * 4861) - (10 * 947)] / [(4 * 30) - (10^2)]

= [19444 - 9470] / [120 - 100]

= 9974 / 20

= 498.7

Next, let's calculate the y-intercept (b):

b = (Σy - mΣx) / n

= (947 - (498.7 * 10)) / 4

= (947 - 4987) / 4

= -4039 / 4

= -1009.75

Now we have the equation of the trend line:

y = 498.7x - 1009.75

To forecast sales in year 5, substitute x = 5 into the equation:

y = 498.7 * 5 - 1009.75

= 2493.5 - 1009.75

= 1483.75

Therefore, the forecasted sales for year 5 is approximately 1483.75.

To forecast sales in year 6, substitute x = 6 into the equation:

y = 498.7 * 6 - 1009.75

= 2992.2 - 1009.75

= 1982.45

Therefore, the forecasted sales for year 6 is approximately 1982.45.

Answer:

x =20.8

Step-by-step explanation:

We can find the value of 1/2 of x using the Pythagorean theorem

a^2 + b^2 = c^2

a^2 + 6^2 = 12^2

a^2 = 36+144

a^2 = 108

Take the square root

sqrt(a^2) = sqrt( 108)

a =sqrt(36*3)

a = sqrt(36) sqrt(3)

a = 6sqrt(3)

Now x = 2 times the length of a

x = 2 * 6 sqrt(3)

x = 12 sqrt(3)

The smallest y value for the solutions of the mixed system of equations y = \(x^{2}\) - x - 20 and y = 3x - 15 is -12.

To find the smallest y value for the solutions of the system, we need to find the point at which the two equations intersect. By setting the equations equal to each other, we can solve for the values of x and y that satisfy both equations:

\(x^{2}\) - x - 20 = 3x - 15

Rearranging the equation, we get:

\(x^{2}\) - x - 3x + 20 - 15 = 0

\(x^{2}\)- 4x + 5 = 0

Factoring the quadratic equation, we have:

(x - 5)(x - 1) = 0

Setting each factor equal to zero, we find two possible values for x: x = 5 and x = 1.

Substituting these values back into either equation, we can find the corresponding y values:

For x = 5:

y = 3(5) - 15 = 0

For x = 1:

y = 3(1) - 15 = -12

Therefore, the smallest y value for the solutions of the system is -12.

Answer:

It's what came out, let me know if it works for you

Step-by-step explanation:

The function f(x) = x³ − 125x² − 25 has neither removable nor non-removable discontinuities.

It is continuous for all real numbers.

We have,

To identify removable and non-removable discontinuities of the function f(x) = x³ − 125x² − 25, we need to look for values of x that make the function undefined or create "holes" in the graph.

A removable discontinuity occurs when there is a hole in the graph at a particular x-value.

It means that the function can be made continuous by defining the value at that point.

A non-removable discontinuity (also known as an essential or infinite discontinuity) occurs when there is a vertical asymptote or an undefined value at a particular x-value, and the function cannot be made continuous by assigning a value at that point.

Now, let's analyze the given function:

f(x) = x³ − 125x² − 25

To identify any removable discontinuities, we need to check for values of x that make the function undefined.

However, this function is a polynomial, and polynomials are defined for all real numbers.

There are no divisions by zero or square roots of negative numbers, so there are no removable discontinuities in this function.

To identify any non-removable discontinuities, we need to look for vertical asymptotes or undefined values.

Since this function is a polynomial, there are no vertical asymptotes or undefined values.

Therefore, there are no non-removable discontinuities in this function either.

Thus,

The function f(x) = x³ − 125x² − 25 has neither removable nor non-removable discontinuities.

The probability that the mean SAT score for a random sample of 50 freshmen will be anywhere from 1075 to 1110 is approximately 0.7396, or 73.96%.

To solve this problem, we will use the Central Limit Theorem, which states that the distribution of sample means approaches a normal distribution as the sample size increases.

Given:

Population Mean (μ): 1100

Standard Deviation (σ): 95

Sample Size (n): 50

We need to find the probability that the mean SAT score for a random sample of 50 freshmen falls between 1075 and 1110.

First, we calculate the standard error of the mean (SEM) using the formula:

SEM = σ / √n

SEM = 95 / √50 ≈ 13.435

Next, we can calculate the z-scores for the lower and upper limits using the formula:

z = (x - μ) / SEM

For the lower limit:

\(z_{lower\) = (1075 - 1100) / 13.435 ≈ -1.861

For the upper limit:

\(z_{upper\) = (1110 - 1100) / 13.435 ≈ 0.745

Now, we can use a standard normal distribution table or calculator to find the probabilities associated with these z-scores.

Using the standard normal distribution table, we find the area to the left of -1.861 is approximately 0.0308, and the area to the left of 0.745 is approximately 0.7704.

To find the probability between these two z-scores, we subtract the smaller area from the larger area:

Probability = 0.7704 - 0.0308 ≈ 0.7396

Therefore, the probability that the mean SAT score for a random sample of 50 freshmen will be anywhere from 1075 to 1110 is approximately 0.7396, or 73.96%.

Sin(X) = 24/40

Cos(X) = 32/40

Tan(X) = 24/32

From the info given, the ratio of Noah's steps to Jada's steps is 15 : 12 = 10 : 8 = 5 : 4 = ⁵/4.

Use this ratio to create a table of 3 pairs of values as shown below.

b. The graph of that shows this relationship has been attached below. Check the attachment.

c. Constant of proportionality can be calculated in each representation as follows: y/x = k. Where y is steps taken by Noah, x is for steps taken by Jada, and I is constant of proportionality.

Thus,

Constant of proportionality (k) = 15/12 = ⁵/4

This means, for every 5 steps taken by Noah, Jada takes 4 steps.

This relationship is represented by the equation, y = ⁵/4x.

The ⁵/4 in the equation is the constant of proportionality of their relationship.

d. The equation, description, graph, and table all represent the same situation because they all show the same constant of proportionality between x and y.

In the equation, ⁵/4 represents the constant of proportionality. In the graph, the slope is ⁵/4, which is also the same last constant of proportionality.

The linearized equation for the non-linear equation z = x² + 4xy + 6xy² in the region defined by 8 ≤ x ≤ 10, 2 ≤ y ≤ 4 is given by :

z ≈ 244 + 20(x - 8) + 128(y - 2).

When using the linearized equation to calculate the value of z at x = 8, y = 2, the error is 0.

1.1. To linearize the equation in the given region, we need to find the partial derivatives of z with respect to x and y:

∂z/∂x = 2x + 4y

∂z/∂y = 4x + 6xy

At the point (x₀, y₀) = (8, 2), we substitute these values:

∂z/∂x = 2(8) + 4(2) = 16 + 8 = 24

∂z/∂y = 4(8) + 6(8)(2) = 32 + 96 = 128

The linearized equation is given by:

z ≈ z₀ + ∂z/∂x * (x - x₀) + ∂z/∂y * (y - y₀)

Substituting the values, we get:

z ≈ z₀ + 24 * (x - 8) + 128 * (y - 2)

1.2. To find the error when using the linearized equation to calculate the value of z at x = 8, y = 2, we substitute these values:

z ≈ z₀ + 24 * (8 - 8) + 128 * (2 - 2)

= z₀
