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?
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.

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°

drag each figure to show if it is similar to the figure shown or why it is not similar
Answer:
In the given shapes above, we can see that all shapes have four sides.
Above geometrical shapes could be named as Rectangles, parallelogram or quadrilateral.
First two shapes are Rectangles.
Third is a parallelogram.
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.
It is called a triangle when a shape has three sided close figure.
So, we could drag : Not similar - Different Type of shape.

7. Higher Order Thinking Nicole scored
8 goals this season. She scored 9 fewer
goals than Julien. How many goals did
Julien score?
Restate this problem using the word more.
Nicole scored 8 goals this season. Julien
scored
Answer:
Julien scored 17 goals (9 more than Nicole)
Step-by-step explanation:
Nicole: 8 goals (x-9) = 8
Julien: x-9 = y
Nicole:
x-9=8
x=17
Julien:
17-9 = 8
Julien scored 9 more goals than Nicole giving Julien 17 goals on the season and Nicole 8 goals
Chad is planting a plant that is 4 inches tall. He wants the hole he is digging to be as deep as the plant is tall. What integer represents the location of the bottom of the hole?
Answer:
-4 in
Step-by-step explanation:
4 inches underground, assuming that ground level is 0, is negative four inches.
-4 represents the location of the bottom of the hole.
What is Integer?An integer is a positive or negative whole number, including 0.
Given that, Chad is planting a plant that is 4 inches tall. He wants the hole he is digging to be as deep as the plant is tall.
According to question
The height of the plant is 4 in, so Chad need to dig a 4 in hole in the ground.
Hence, -4 represents the location of the bottom of the hole.

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?
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
Teresa use 1/2 gallons of milk for one batch of hot chocolate if she use 3/4 gallons of milk the morning how many batches of hot chocolate did she make
Answer: 1 and a half batches
Step-by-step explanation: because 1/2 is the same as 2/4 so the half of two is 1 so if you add one to the 2/4 you get 3/4 and that is the same as 1 1/2 batches

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

If X and Y are two points on number line then the distance between them is represented by
Answer:
Step-by-step explanation:
Let the point X be represented as (x1, y1) and the point Y be (x2, y2). The distance between the two points is expressed as;
D² = (x2-x1)² - (x2-y2)²
Take the square root of both sides;
√D² = √(x2-x1)² - (x2-y2)²
D = √(x2-x1)² - (x2-y2)²
Also the distance between X and Y can be represented as D = |X-Y|
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
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
