For the given points (6, y) and (-8, 4) having slope = 1/7 the value of y = 10.

What is the slope of a line?

A line's slope, also known as its gradient, is defined as the value of a line's steepness or direction in a coordinate plane. Slope can be calculated using various methods given a line equation or the coordinates of points on a straight line.

If P(a, b) and Q(c, d) are two given points on a coordinate plane, then the slope of line PQ can be computed using the formula

                      [tex]Slope(m)=\frac{d - b}{ c - a}[/tex]

The given points are (6, y) and (-8, 4).

and the slope of the line is given as m = 7.

By using the slope of a line formula, we get

                       [tex]m = \frac{8-y}{-8-7}\\\\ \frac{1}{7}= \frac{8-y}{-8-7}\\\\\frac{1}{7}= \frac{8-y}{-14}\\\\\\8-y=-2\\y=8+2\\y=10[/tex]

Hence,  the value of y is 10.

The area of the rectangle is given by the formula below:

A = 18x^2 - 27x + 7

For a rectangle of width W and length L, the area is given by the formula:

A = W*L

Here we know that the dimensions of a rectangle are 6x-7 and 3x-1, then we can define:

L = 6x - 7

W = 3x - 1

Replacing that in the area formula above we will get:

A = (6x - 7)*(3x - 1)

Now we can expand that product:

A = (6x)*(3x) + (6x)*(-1) + (-7)*(3x) + (-7)*(-1)

A = 18x^2 - 6x - 21x + 7

A = 18x^2 - 27x + 7

The probability that the fish is at most 0.5 meters away from the center of the container, considering the volume of the cube, is given as follows:

0.0723 = 7.23%.

The volume of a cube of side length s is given by the side length cubed, that is:

V = s³.

The cube in this problem has a side length of 1.2 meters, hence the volume is given as follows:

V = 1.2³ = 1.728 cubic meters.

Considering only the inner 0.5 meters of the cube, the volume is given as follows:

V = 0.5³ = 0.125 cubic meters.

A probability is given by the division of the number of desired outcomes by the number of total outcomes, hence:

p = 0.125/1.728 = 0.0723 = 7.23%.

The derivative of the natural log function y = e^(-1/x^2) is

The given function is

y = e^(-1/x^2)

The given function is rearranged as

y = e^(-1/x^2) = e^u such that u = (-1/x^2)

Applying chain rule

y = e^u

y' with respect to u = e^u

u = (-1/x^2) = -x^(-2)

u' with respect to x = 2x^(-3)

(y' with respect to u) *  (u' with respect to x)

= e^u * 2x^(-3)

Applying the area of square and triangle, the amount of paper needed is:  180 inches².

The area of a square shape = (side length of the shape)².

The area of a triangular shape = 1/2(base)(height)

The diagram that illustrates the problem given is shown in the image attached below, where the triangular paper to cover the triangular plank and the square paper for the square plank are shown also with their dimensions.

Therefore, the amount of paper that would cover the piece of art = area of the square shape + area of the triangular shape.

Area of the square shape = 12² = 144 inches²

Area of the square shape = 144 inches²

Area of the triangular shape = 1/2(12)(6)

Area of the triangular shape = 36 inches²

Amount of paper needed = 36 + 144

The mean score of all the students is 79.5 and it is round off into one decimal place.

Mean

Mean refers the average of the given numbers and is calculated by dividing the sum of given numbers by the total number of numbers.

Given,

In a psychology class, 30 students have a mean score of 87.7 on a test. Then 21 more students take the test and their mean score is 67.7.

Here we need to find the mean score of all students.

In order order to find the mean score, we have to calculate the total score of the students by multiplying the mean score by the number of students then we get,

=> 30 x 87.7 = 2631

Similarly, the total score for 21 students is,

=> 21 x 67.7 = 1421.7

So, the 51 students, cumulative score is

=> 2631 + 1421. 7 = 4052.7

Therefore, the mean score is calculated as,

=> 4052.7/51

=> 79.464

When we round off the value into one decimal place then we get

=> 79.5

Therefore, the mean value of all the students is 79.5.

Option A is correct. The value of function (f/g)(x) is found to be  [tex]\sqrt[3]{3x}[/tex]/(3x+2) where the condition is that  x ≠  -2/3.

In mathematics, function composition is an operation in which two functions, f and g, form a new function, h, in such a way that h(x) = g(f(x)). This signifies that function g is being applied to the function x. So, in essence, a function is applied to the output of another function.

The new function obtained by performing f first and then g is the combination of two functions g and f.

Given:

f(x) = [tex]\sqrt[3]{3x}[/tex]

g(x) = 3x + 2

(f/g)(x) =  [tex]\sqrt[3]{3x}[/tex]/(3x+2)

Also, the denominator should not be equal to 0.

So, 3x + 2 ≠ 0

     x ≠  -2/3

A residual plot is a plot that shows the difference between the observed response and the fitted response values.

The ideal residual plot is usually called the null residual plot, and it shows a random scatter of points that form an approximately constant width band around the identity line.

When it comes to finding out if a linear model will be suitable, we can say that the points will form a pattern when the model function is not correct.

Now, you might be able to transform variables or even add polynomial and interaction terms in order to remove the pattern.
