The measure of the variability in the response variable that is not explained by the regression model is known as the residual sum of squares (RSS).
RSS is calculated by summing the squared differences between the predicted values (from the regression model) and the observed values of the response variable.Measuring Variability in the Response Variable with Residual Sum of SquaresThe residual sum of squares (RSS) is a measure of the variability in the response variable that is not explained by the regression model. It is calculated by summing the squared differences between the predicted values (from the regression model) and the observed values of the response variable. RSS is often used to measure the goodness of fit of a regression model and to compare different models. A lower RSS indicates a better fit. RSS can also be used to identify influential observations and outliers that may have a large impact on the regression results.

What is the average speed of the car if it covers 400 km in 8 hours?
An object's average speed is a measurement of how quickly it moves over a predetermined amount of time. The calculation is done by dividing the overall distance travelled by the overall travel time. In other words, it reveals the average amount of distance an object has travelled per unit of time.
In the case provided, we can apply the following calculation to get the average speed of the car:
average speed = total distance / total time
In this instance, a total of 400 kilometers was travelled and 8 hours were expended.
average speed = 400 km / 8 hours
= 50 km/h
This means that the average speed of the car is 50 kilometers per hour. This is the average speed at which the car traveled over the 8 hour period. It does not necessarily mean that the car was traveling at exactly 50 km/h for the entire 8 hour period, It could have gone faster or slower at different times, but on average it traveled at 50 km/h.
Therefore ,average speed of the car is 50 km/h .

You want the circumcenter of the triangle defined by the points A(5, 7), B(-5, -6) and C(5, -6).
Right triangleThe fact that point C shares a coordinate with each of points A and B suggests the triangle is a right triangle. Graphing the points confirms this.
The circumcenter is the midpoint of the hypotenuse of that right triangle, so is ...
circumcenter = (A +B)/2
circumcenter = ((5, 7) +(-5, -6))/2 = (5-5, 7-6)/2 = (0, 1)/2
circumcenter = (0, 0.5)

The scale of a map is 1 cm : 85 km. B
a) A river on the map is 14 cm long. Calculate the actual length of the river in kilometres.
b) The actual distance between two towns is 765 km. Calculate the distance between these towns on the map
a) By multiplication a river on the map being 14 cm long has the actual length of 1190 km.
b) By division the actual distance between two towns being 765 km has the distance of 9 cm on the map.
What is multiplication?
The fundamental concept of repeatedly adding the same number is represented by the process of multiplication. The results of multiplying two or more numbers are known as the product of those numbers, and the numbers that are multiplied are referred to as the factors.
The value of 1 cm on map is a = 85 km.
The measurement of the river on the map b = 14 cm.
The actual length of the river = x.
Use the arithmetic operation of multiplication -
x = a × b
x = 85 × 14
x = 1190
Therefore, the measurement of river is 1190 km.
The actual distance between two towns is c = 765 km.
The distance on the map = y.
Use the arithmetic operation of division -
y = c/a
y = 765/85
y = 9
Therefore, the distance of two towns is 9 cm.

Can someone help me understand this?
Answer:
see attached
Step-by-step explanation:
You are given two solutions to a 3-step inequality and are asked to describe them.
3-Step inequalityThese inequalities have variable terms and constant terms on both sides of the comparison symbol. The expressions have been simplified.
These inequalities can be described as 3-step, because a straightforward solution can be accomplished in 3 steps. The first two steps separate the constant and variable terms, and the final step divides by the coefficient of the variable.
The process is virtually identical to that for solving a 3-step equation.
AllisonAllison's first step is to get rid of one of the unwanted variable terms by subtracting it from both sides. She chose the "3x" term, which has a smaller coefficient than the "5x" term, so the resulting difference will leave a positive coefficient on the x-term.
Then she removed the unwanted constant from the side with 2x by adding its opposite.
Since the x-term has a positive coefficient, Allison did not have to change anything about the inequality symbol when she divide both sides by that coefficient.
JohnJohn used a first step similar to Allison's but he chose to eliminate the 5x term. The result was the x-term ended up with a negative coefficient. That introduces an extra bit of procedure at the end when he divides by the -2 coefficient of x: the inequality symbol must be reversed.
The constant term on the side with the x-term was removed by adding its opposite. This is the same step Allison performed as step 2.
When John finally divides by the coefficient of x, he has to reverse the inequality symbol, since that coefficient is negative.

The points (4, 1) and (x,-6) lie on the same line. If the slope of the line is 1, what is the value of x?
Answer:
-3
Step-by-step explanation:
You want the value of x in (x, -6) so that this point lies on a line with slope 1 through point (4, 1).
Point-slope equationThe point-slope equation for a line with slope m through point (h, k) is ...
y -k = m(x -h)
The line with slope 1 through point (4, 1) can be written as ...
y -1 = 1(x -4)
ApplicationWe want the value of x when y=-6.
y +3 = x . . . . . . . add 4 to solve for x
-6 +3 = x = -3
The value of x is -3.

5x - Зу = -2
Solve the system algebraically.
Substitute the first equation into the second equation.
5x - 3( 12 - 4x) =-2
Distribute.
5x - 36 + 12x = -2
Combine like terms.
17x -36 = -2
Add 36 to each side
17x -36+26 = -2+36
17x = 24
Divide by 17
17x/17 = 34/17
x = 2
Answer:
x = 2
y = 4
Step-by-step explanation:
y = 12 - 4x ⇒ ( 1 )
5x - 3y = -2 ⇒ ( 2 )
Let us find the value of x.
For that, take equation (2) and replace y with ( 12 - 4x ).
5x - 3y = -2
5x - 3 ( 12 - 4x ) = -2
5x - 36 + 12x = -2
Combine like terms.
17x - 36 = -2
Add 36 to both sides.
17x = -2 + 36
17x = 34
Divide both sides by 17.
x = 2
Let us find the value of y.
To find the value of y let us take equation ( 1 ) and replace x with 2.
y = 12 - 4 × 2
y = 12 - 8

yards will she catch up? *
As per given data of Lexi and Brittany runs , the number of seconds and yards taken by Lexi to catch up Brittany is 6 seconds and 30 yards respectively.
As given in the question,
Let us consider,
Time taken by Brittany be 't₁ '
Time taken by Lexi be 't₂'
Brittany runs at the speed of 5 yards per seconds
Lexi runs at the speed of 7 yards per seconds
Distance covered by Brittany be 'x' yards
Distance covered by Lexi be 'x + 12 ' yards
t₁ = x / 5
t₂ = ( x + 12 ) / 7
When Lexi catch up Brittany
t₁ = t₂
⇒ x / 5 = ( x+ 12 ) / 7

(a) (i) Calculate the total volume of the solid. [The volume of a hemisphere of radius r is given by V = ¹.] [The volume of a cone of radius r and height h is given by Varh.
Answer:
Step-by-step explanation:
V = 2/3 * pi * r3 gives the volume of a hemisphere of radius r.
V = 1/3 * pi * r2 * h gives the volume of a cone with radius r and height h.
We may compute the volume of both forms using the hemisphere's radius and the cone's base radius of 7 cm:
Hemisphere Volume = 2/3 * pi * (7 cm)3 = (14/3) * pi * 343 cm3 = 615.75 cm3
Cone Volume = 1/3 * pi * (7 cm)2 * 13 cm = 49 * pi * cm3 = 153.94 cm3
To get the overall volume of the solid, sum the volumes of the hemisphere and cone:
Volume total = 615.75 cm3 + 153.94 cm3 = 769.69 cm3
As a result, the total volume of the solid is 769.69 cm3.
