PLEASE HELP! 100 POINTS AND BRAINLIEST!! Im Really Stuck On This So Please Help If You Can! E) Calculate

Answers

Answer 1

Answer:

In the simplest meaning, you have:

Residual (e) = Observed value (y) - Predicted value (y')

Here, observed value y has been provided in table.

The predict value y' is calculated based on the linear regression model shown in your picture: y = 0.161x + 0.748, by substitute x into this model, you obtain the predict value y'.

x = 1.11, 18, 21.9, 18, 16.7, 20, 15.5, 19.5

=> Corresponding y' would be:

y' = 0.93, 3.65, 4.27, 3.65, 3.44, 3.97, 3.24, 3.89

From the table, you have corresponding observed value y:

y = 0.7, 4, 3.69, 3.8, 3.21, 4, 3.92, 3.77

=> Subtract y to y', you obtain the corresponding residual e:

e = -0.23, 0.35, -0.58, 0.15, -0.23, 0.03, -0.68, -0.12

Plot vector e on y axis, and vector x on x-axis respectively, you got the residual plot

Hope this helps!

Answer 2

Answer:

E) -0.23, 0.35, -0.58, 0.15, -0.23, 0.03, -0.68, -0.12

F) on the horizontal axis, take the x values and on the vertical axis, take residuals

Step-by-step explanation:

Given:

y = 0.7, 4, 3.69, 3.8, 3.21, 4, 3.92, 3.77

Using the regression equation:

y' = 0.93, 3.65, 4.27, 3.65, 3.44, 3.97, 3.24, 3.89

Residuals: y - y'

-0.23, 0.35, -0.58, 0.15, -0.23, 0.03, -0.68, -0.12

determine the intercept of the line​

Answers

Answer:

X intercept is (-8,0), Y intercept is (-6,0)

Step-by-step explanation:

The intercept is where the line crosses the X and Y axis, so in this line, the line crosses the x axis at (-8,0) and the y axis at (-6,0).

Answer:

There are two different intercepts in this linear line. The x - intercept would be at (-8, 0), and the y - intercept would be at (0,-6). To find out which is the x - intercept and which is the y - intercept, remember that x is always horizontal and y is always vertical.

You cannot have the range of a number in negative numbers. The range will always be in positive numbers, and the range will never be in a fraction.

The range of the graph is all real numbers.

Each domain and range are the set of all actual numbers. however, due to the fact, absolutely the fee is described as a distance from 0, the output can only be greater than or identical to zero. The domain is all real numbers since the horizontal extent of the graph is the complete real range line.

Answer:

Find the volume of the sphere.  

Either enter an exact answer in terms of π or use 3.14 for π and round your final answer to the nearest hundredth.

The radius is 1

Volume = [tex]\frac{4}{3} \pi[/tex]  or 4.19

Step-by-step explanation:

Given

Radius, r = 1

Required

Find the volume of sphere

Volume of a sphere is calculated using the following formula

[tex]V = \frac{4}{3} \pi r^{3}[/tex]

Where V = Volume and r = radius

By Substitution,

[tex]V = \frac{4}{3} \pi * 1^{3}\\\\V = \frac{4}{3} \pi * 1\\\\V = \frac{4}{3} \pi[/tex]

Solving further to get the numerical value of volume;

We have to substitute 3.14 for π

[tex]V = \frac{4}{3} * 3.14V = 4.1866[/tex]

V = 4.19 to the nearest hundredth

Each steak surface requirement = 0.25 square feet of the grill.

Maximum number of steaks mike can grill at

2.5 feet

2 feet and

3.5 feet

What is Parabola?

A parabola is a U-shaped curve this is drawn for a quadratic function,

f(x) = ax² + b x + c. The graph of the parabola is downward (or opens down), when the price of a is much less than 0, a < 0. The graph of the parabola is upward (or opens up) when the value of a is more than 0, a > 0.

parabola, open curve, a conic segment produced via the intersection of a proper circular cone and a plane parallel to an element of the cone.

On a coordinate plane, a line with a negative slope goes through points (0, 1.5) and (2, 1)

So this is a linear function

what are two methods you can use to find the area of a square. I WILL GIVE BRAINLIEST I NEED HELP QUICKKKKK

Answers

Answer:

To find the area of a rectangle multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area. This is the same as saying length2 or length squared.

Step-by-step explanation:

Answer:

For a rectangle, you get the length and width and multiply them

For a Square, you have to find one side length and mulitply it by itself

or you can split the square with a diagonal into 2 triangles, get the area of each and add them up

or split the square in half and find the area of both rectangles and then add them together

Step-by-step explanation:

For example, if the measure of one side of a square is 5, because all the other lengths are the same, you do 5 times 5 which equals 25 or 5^2 which is 25
