Step-by-step explanation:

1. brackets

in the bigger bracket there is a smaller one do it first

(45-(6+3))x27= (45-9)x27

2. the bracket again

(45-9)x27 = 36 x 27

3. multiply

36x27=972

Suppose that the total sum of squares of the dataset is 1,032, and the sum of squares due to error is 76, what is the sum of squares due to regression?

Answers

Answer:

The sum of squares due to regression is 956.

Step-by-step explanation:

The sources of variation while doing regression analysis are typically called Regression and Residual. Regression is the portion that can be explained by the regression equation and the Residual is the portion that is left unexplained by the regression equation.

The relation between total variation (SST), explained variation (SSR) and unexplained variation (SSE) is,

SST = SSR + SSE

It is provided that:

SST = 1032

SSE = 76

Compute the value of SSR as follows:

SST = SSR + SSE

SSR = SST - SSE

       = 1032 - 76

       = 956

Thus, the sum of squares due to regression is 956.

The length of a Rectangle is five less than twice its width the perimeter is 26 m find the dimensions of the rectangle

Answers

Answer:

L = 7 m

W = 6 m

Step-by-step explanation:

P = 2L + 2W

26 = 2(2W - 5) + 2W

26 = 4W - 10 + 2W

26 = 6W - 10

+10.         +10

36 = 6W

divide both sides by 6

36/6 = W

6 = W

L = 2(6) - 5

L =12 - 5 = 7

Which equation represents a line which is perpendicular to the line y= –1/8x + 8

1. X+8y=8
2x– 8y = 8
3 8x+y=5
4 y-8x=4

Answers

An equation which represents a line which is perpendicular to the line y= –1/8x + 8 is: 4. y - 8x = 4.

How to interpret the slope?

Mathematically, the standard form of the equation of a straight line is given by this mathematical expression;

y = mx + c

Where:

m represents the slope.x and y are the points.c represents the intercept.

In Mathematics, the condition for perpendicularity of two lines is given by:

m₁ × m₂ = -1

Next, we would rewrite the given equation representing a line in standard form:

x + 8y = 8  

y = -x/8 + 1

Therefore, slope (m) = -1/8 (Not perpendicular).

x - 8y = 8

y = x/8 - 8

Therefore, slope (m) = 1/8 (Not perpendicular).

8x + y = 5

y = -8x + 5

Therefore, slope (m) = -8 (Not perpendicular).

y - 8x = 4

y = 8x + 4

Therefore, slope (m) = 8 (perpendicular).

Check:

m₁ × m₂ = -1

-1/8 × 8 = -1

I got f(x)=7

Really, f(x) is kind of like y. So, just plug in you x value, 4, into the x next to the 1/2 and solve! (I have a picture of my work if you were wanting)! In the end you get f(x)=7

3. Consider the equation s +10 = 25.
(a) Write a real-world problem that can be solved using the equation
(b) What does s represent in your scenario?

Answers

Answer:

Step-by-step explanation:

Given the equation s+10 = 15

Converting this to a statement. Let the unknown value e s;

Ade travels to his hometown at a speed of s m/s while Sholla travels at a speed of 10m/s, if their total speed is 25m/s, find the speed of Ade.

b) To get g speed of Ade, we will evaluate the expression

s+10= 25

Subtract 10 from both sides

s+10-10= 25-10

s = 15

Hence Ade travelled at a speed of 15m/s

Fourth and fifth shapes are Rectangles again.

Also we can say all those shapes with four side as quadrilaterals. (Note: A quadrilateral has four sides.)

Below shown shape has only three sides in it.

Answer:

x = 11.83°

Step-by-step explanation:

Equations

The figure shows two parallel lines crossed by a line. We have completed the figure with another variable y. Please see the attached image.

Angles y and 4x+28 are linear, thus their sum is 180°:

y + 4x + 28 = 180

Angles y and 8x + 10 are corresponding, thus

y = 8x + 10

Substituting:

8x + 10 + 4x + 28 = 180

Simplifying:

12x + 38 = 180

Subtracting 38:

12x = 142

Dividing by 12

x = 11.83°

When the value of the y-intercept(b) change by subtracting a number from "b" in the equation "y=mx+b", the graph will move of shift down ? true or false

Answers

Answer:

True. The graph will shift down if we subtract a number from "b"

Step-by-step explanation:

"b" represents the y-intercept, or how high up on the y axis the graph intersects.

If we don't change anything except for the y-intercept, then the graph should only move up or down.

Because we are decreasing the value of "b" the y intercept will decrease, dragging the graph of y down.
