What does a residual value of 1.3 mean when referring to the line of best fit of a data set?A data point is 1.3 units above the line of best fit.
A data point is 1.3 units below the line of best fit.
The line of best fit has a slope of –1.3
The line of best fit has a slope of 1.3.

Answers

The residual value of 1.3mean when referring to the lineofbestfit of a data set is that a data point is 1.3 units above the line of a data set. This is because the given residual value is positive. So, the data point is above the best fit line.

Residual value:

A residual value is the standard square error which is calculated from the line of best fit.
If the residual value 'r' is positive it means the data point is r units above the best fit line.
If the residual value 'r' is negative it means the data point is r units below the best fit line.

Line of best fit:

A line of best fit refers to a line through a plot of datapoints that best expresses the relationship between those points.

For the given residualvalue of 1.3 mean, a data point is 1.3unitsabove the line of best fit when referring to the line of best fit of a data set. This is because the residual value is positive.

So, Option A is correct.

How do you factor x^4-36?

Answers

The solution to your problem is as follows:

x^4 - 36=(x^2+6)(x^2-6)

Therefore, the factors of x^4-36 are (x^2+6) and (x^2-6).

I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!

The factors of $x^4-36$ are ( $x^2$ - 6) ( $x^2$ + 6) using Algebraic identity.

Given Equation: $x^4-36$

Factorization, the process of breaking down a number into smaller numbers which when multiplied together arrive at the original number.

So, $x^4$ can be written as $(x^2)^2$

and, 36 can be written as 6².

So, $x^4-36$ = $(x^2)^2$ - 6².

Using the Algebraic identity as

$(a^2 - b^2)= (a-b)(a+b)$

Then, using the above identity in $(x^2)^2$ - 6² as

$(x^2)^2$ - 6² = ( $x^2$ - 6) ( $x^2$ + 6)

Therefore, the factors of $x^4-36$ are ( $x^2$ - 6) ( $x^2$ + 6).

Answer:

m = 1/4
b = 2
y = 1/4x +2

Step-by-step explanation:

The slope is the ratio of rise to run. The rise between the two points is 2 units; the run is 8 units, so the slope is ...

m = rise/run = 2/8 = 1/4

The y-intercept (b) is the y-value where the line crosses the y-axis. For this line, that is y = 2, so b = 2.

Putting these values of m and b into the equation y = mx +b gives ...

y = 1/4x +2

Choose the abbreviation of the postulate or theorem that supports the conclusion that the triangles are congruent.Given:
∠C, ∠F are rt. ∠'s; AC = DF; ∠B = ∠E

HL
LL
HA
LA

Answers

∠C and ∠F are right angles. So, the triangles are right triangles.

AC = DF are the short legs of both triangles.

∠B = ∠E.

In this scenario, the postulate is ASA (Angle-Side-Angle)

The remaining sides that must be noted to prove that the triangles are congruent are the long legs and hypotenuse.

CB = FE can be LL for congruence where tt states that if the legs of one right triangle are congruent to the legs of another right triangle, then the triangles are congruent.

Nameof postulate or theorem that supports the conclusion that the triangles are congruent is Angle-side-Angle (ASA).

Given information:

$\angle C,\; \angle F$ are right triangle, $AC=DF;\angle B=\angle E$
