Answer:

I will gladly help (see explanation)

Step-by-step explanation:

1. 8.21n−5.3−(7+11.8n)

Distribute the Negative Sign:

=8.21n−5.3+−1(7+11.8n)

=8.21n+−5.3+(−1)(7)+−1(11.8n)

=8.21n+−5.3+−7+−11.8n

Combine Like Terms:

=8.21n+−5.3+−7+−11.8n

=(8.21n+−11.8n)+(−5.3+−7)

=−3.59n+−12.3

(Hope his helped, Good Luck! )

Answer:

-3.59 - 12.3

Step-by-step explanation:

Algebraic Expressions are similar to numerical expressions but instead of just numbers, alphabet variables are being used as well.

Note: BODMAS rule applies to Algebraic Expressions as well.

Eg. 7x + 4 + 5y + 4x = 11x + 5y + 4

Given from the question:

(8.21n - 5.3) - (7 + 11.8n)

= 8.21n - 5.3 - 7 - 11.8n

= 8.21n - 11.8n - 5.3 - 7

= -3.59n - 12.3

Therefore, the answer is -3.59 - 12.3.

The minimum sample size needed for the desired margin of error of the confidence interval is given as follows:

44.

The sample size needed is obtained using the z-distribution, as the standard deviation for the population is known.

The equation that gives the margin of error for a z-distribution confidence interval is:

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

In which the parameters are given as follows:

The known measures in this problem are given as follows:

[tex]M = 20, \sigma = 80, z = 1.645[/tex]

Then the desired sample size is obtained as follows:

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

[tex]20 = 1.645\frac{80}{\sqrt{n}}[/tex]

[tex]20\sqrt{n} = 1.645 \times 80[/tex]

Simplifying by 4, we have that:

[tex]\sqrt{n} = 1.645 \times 4[/tex]

[tex](\sqrt{n})^2 = (1.645 \times 4)^2[/tex]

n = 43.3.

Rounding up, as a sample size of 43 would have a margin of error slightly  above 20, the sample size needed is of 44.

The end behaviour of the function [tex]y = -x^{2} + 4[/tex] is

f(x) → −∞, as x → −∞

f(x) → −∞, as x → +∞

The degree of the function is even, and the leading coefficient is negative.

End behaviour of a function:

A polynomial function's final behaviour is how its graph behaves as x gets closer to positive or negative infinity.

The graph's final behaviour is determined by a polynomial function's degree and leading coefficient.

For very big or very small values, the leading coefficient is more important than the other function coefficients. Therefore, it is sufficient to forecast the function's final behaviour based on the sign of the leading coefficient.

To predict the end-behaviour of a polynomial function, first check whether the function is odd-degree or even-degree function and whether the leading coefficient is positive or negative.

1. The position (distance covered) of each elevator relative to the surface after additional 17 seconds is as follows:

2. After 17 seconds, the miners' elevator is deeper by 79 feet than the equipment elevator.

Distance is a function of speed and time.

This implies that distance is the product of speed and time.

The descent speed of the equipment elevator = 4 feet per second

The total time in seconds the equipment elevator descended = 44 seconds (27 + 17)

The descent distance covered in 44 seconds = 176 feet (44 x 4)

The descent speed of the miners' elevator = 15 feet per second

The total time in seconds the miners' elevator descended = 17 seconds

The descent distance covered in 17 seconds = 255 feet (17 x 15)

Thus, the difference in the descent distance between the equipment elevator and the miners' is 79 feet (255 - 176).

The two solutions are (0, 1) and (-4, 0)

From the question, we have the following parameters that can be used in our computation:

Graph of a linear relationship

From the graph of the linear relationship, we have the following points on the line

(0, 1) and (-4, 0)

Hence, the solutions are (0, 1) and (-4, 0)

On the graph, we can see that as x increases, the y value increases

This means that the graph is an increasing graph

In (a), we have

(0, 1) and (-4, 0)

These points represent the intercepts

So, we have

x-intercept= -4

y-intercept = 1

The slope of the line is then calculated using the following slope equation

Slope = (y₂ - y₁)/(x₂ - x₁)

Where

(x, y) = (0, 1) and (-4, 0)

Substitute the known values in the above equation

So, we have the following equation

Slope = (0 - 1)/(-4 - 0)

Evaluate

Slope = 0.25

The Equation for the given line in the graph is x+ y = 3.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

Given:

From the Graph take two points (0, 3) and ( 3, 0)

So, slope for the line

= ( 0-3 ) ( 3-0)

= -3/3

So, the Equation of line is

y[tex]- y_1[/tex]  = m(x[tex]-x_1[/tex])

7 ÷ x = 1.5 is the equation used to solve for x.

Given,

Triangle DEF is a scaled copy of triangle ABC.

We have to find the equation to solve for x.

Scaled Copy;-

 A scaled copy is a representation of a figure in which each length from the original representation has been multiplied by the same amount. Triangle ABC, for instance, is a scaled version of triangle DEF. Triangle DEF's side lengths were calculated by multiplying each side length from triangle ABC by 1.5.

Here,

Length of side AB = 6

Length of side DE = 4

Let y be the value used for scaling.

Then,

6 = 4y

y = 6/4 = 1.5

So,

Length of side BC ÷ x = 1.5

7 ÷ x = 1.5

7 = 1.5x

x = 7/1.5

x = 4.67

Answer: 97 degrees Celsius is 206.6 degrees Fahrenheit.

13 cars needed both repairs and 10 cars needed new brakes, but not a new exhaust system.

In the given question, at Automotive Shop, 50 cars were inspected. 23 of the cars needed new brakes, 34 needed new exhaust systems, and 6 cars needed neither repair.

(a) We have to find the how many cars needed both repairs.

Total inspected cars = 50

The cars needed new brakes = 23

The cars needed new exhaust systems = 34

The cars needed neither repair = 6

So the cars that needed repair = 50-6 = 44

Total cars that needed new brakes and new exhaust systems = 23+34 = 57

So, the cars that needed both repairs = 57-44

The cars that needed both repairs = 13

Hence, 13 cars needed both repairs.

(b) Now we have to find how many cars needed new brakes, but not a new exhaust system.

The cars needed new exhaust systems = 34

The cars that needed repair = 44

So, the cars needed new brakes, but not a new exhaust system = 44-34

The cars needed new brakes, but not a new exhaust system = 10

Hence, 10 cars needed new brakes, but not a new exhaust system.

An equation in point-slope form for the line that passes through (2,-5) and is perpendicular to the graph of y=3x+1 is y = -1/3x-17/3.

When the line to be examined slope is known, and the provided point also serves as the y intercept, the slope intercept formula, y = mx + b, is utilized (0, b). B stands in for the y value of the y-intercept point in the formula. In order to make it simple to identify the slope and y-intercept of a line, its equation can be written in the slope-intercept form. The y-intercept, or point where the line crosses the y-axis, is referred to as the slope.

Perpendicular line slopes are reciprocals with a negative sign. In the slope-intercept form, y = mx + b, where m is the slope, the supplied line, y = 3x+1, is already in the slope-intercept form.

The line in the example has a slope of 3.

The negative reciprocal of three, or -1/3, is the slope of the perpendicular.

Y = -1/3x + b is the equation for the line that we are looking for.

We must track down b. We solve for b by using the x and y coordinates of the provided location as x and y in the equation above.

y = -1/3x + b

5 = (1/3)(2) + b

5 = (2/3) + b

b = -5-(2/3)

b= -17/3

B is now substituted for in the equation

y = -1/3x-17/3 as we know that b =-17/3.

Therefore, an equation in point-slope form for the line that passes through (2,-5) and is perpendicular to the graph of y=3x+1 is y = -1/3x-17/3.

The standard error of the sampling distribution is given by the formula SE = sqrt( (SD1² / n1) + (SD2² / n2) )

As per the question, we are given that samples of size 51 are drawn from population A with a standard deviation of 5.49, and samples of size 76 are drawn from population B with a standard deviation of 5.06.

Substituting these values into the formula, we get:

SE = √( (5.49² / 51) + (5.06² / 76) )

SE = √( (30.11) + (17.93) )

SE = √(48.04)
