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.

Jalil and Victoria are each asked to solve the equation ax – c = bx + d for x. Jalil says it is not possible to isolate x because each x has a different unknown coefficient. Victoria believes there is a solution, and shows Jalil her work:
Answers
Answer:
[tex]x=\frac{d+c}{a-b}[/tex]
Step-by-step explanation:
The equation is:
a x - c = b x + d
so we subtract b x from both sides to group the terms that contain x on the left:
a x - b x - c = d
add c to both sides to isolate the terms in x on the left:
a x - b x = d + c
extract "x" as common factor on the left using distributive property backwards:
x (a - b) = d + c
divide both sides by the quantity (a - b) to isolate the "x":
x = (d + c) / (a - b)
or: [tex]x=\frac{d+c}{a-b}[/tex]
what is the value of f(x)=1/2x+5 when x=4
Answers
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
Good luck, I hope this helps!! :)
If f(x) = -x^2 + 6x - 1 and g(x) = 3x^2 - 4x-1, find (f - g)(x).
A. (f- g)(x) = -4x^2 - 2x
B. (f- g)(x) = 2x^2 + 2x-2
C. (f- g)(x) = 4x^2 - 10x
D. (f - g)(x) = -4x^2 + 10x
Answers
Answer:D
Step-by-step explanation:
(f-g)(x)= -x^2+6x-1- (3x^2-4x-1)
(f-g)(x)= -x^2+6x-1 -3x^2+4x+1
(f-g)(x)= -x^2-3x^2+6x+4x-1+1
(f-g)(x)= -4x^2+10x

Answers
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.

Answers
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.
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
