A home improvement store advertises 60 square feet of flooring for $280.00 including an $70.00 installation fee.How much does each square foot of flooring cost?

Answer:

a. n < k + 1

Step-by-step explanation:

Multiple linear regression model is used for analyzing the linear relationship between the independent variables and dependent variable. It is used when there is the need to predict the relationship of a variable based on the values of two or more other variables. These variables could be nominal, ordinal, or interval/ratio level variables.

Some assumptions of multiple linear regression analysis are:

i.  There must be a linear relationship between the outcome variable and the independent variables.

ii. The residuals are normally distributed.

iii. That the independent variables are not highly correlated with each other.

The assumption that there are no exact linear relationships among the independent variables in a multiple linear regression model fails if n < k + 1.

Answer:

Answer:

(-3,-6)

Step-by-step explanation:

Answer:

100/7 --> 50/3.5 --> 25/1.75 . If we're assuming, without a calculator, we can just say 1.75 ~ 2. So 25/2 = 12.5 as an approx .

But actually, 100/7 -- with no assumptions etc, is just 14.28571429

Answer:

B

Step-by-step explanation:

took the assignment

The ellipse is obtained by slicing the cone at an angle. Then the correct option is B.

A shape made up of a surface and a round cone intersecting. A conic section is sometimes a circle, an ellipse, a parabola, or a hyperbola, based on the direction of the surface with regard to the conical.

The ellipse is obtained by slicing the cone at an angle that passes through the surface of the cone.

Then the correct option is B.

Answer:

x/2 + y√3/2 = 4

Step-by-step explanation:

Step 1: Apply formula

Formula for this problem is :-

xcosα + ysinα = p

Step 2: Substitute values

xcos(60°) + ysin(60°) = 4

x(1/2) + y(√3/2) = 4

x/2 + y√3/2 = 4

Step-by-step explanation:

let's simply get the area of the larger square, and then get the area of the smaller square and subtract the area of the smaller square from that of the larger square, what's leftover is the shaded region.

[tex]\stackrel{\textit{area of the larger square}}{(4x-6)(4x-6)\implies \stackrel{F~O~I~L}{16x^2-48x+36}} ~\hfill \stackrel{\textit{area of the smaller square}}{(x)(x)\implies x^2} \\\\[-0.35em] ~\dotfill\\\\ (16x^2-48x+36)~~ - ~~(x^2)\implies 15x^2-48x+36 \\\\\\ 3(5x^2-16x+12) \implies 3(5x-6)(x-2)[/tex]

Answer:

Rahim is 14 and his father is 42.

Step-by-step explanation:

Let F be Rahim's father's age and R is Rahim's age.

We learn that:

F = 3R  [Rahim's father's age is 3 times as old as him]

and

F + R = 56  [their sum is 56]

----

We have 2 equations and two unknowns, so we should be able to find the answers.

Rearrange the second equation to:  F = 56 - R

The use that definition of F in the first equation:

F = 3R

(56-R) = 3R

Then we can find R:

56-R = 3R

4R = 56

R = 14

Since R=14 and F + R = 56,

F + R = 56

F + 14 = 56

F = 42

Check

Does F=3R?

42 = 3(14)?  YES

Does F + R = 56?

42 + 14 = 56?  YES

Rahim is 14 and his father is 42.

Answer:

= -2/x^3

Step-by-step explanation:

Possible derivation:

d/dx(d/dx((x^2 + 2 x - 1)/x))

Distribute 1/x through x^2 + 2 x - 1:

= d/dx((d/dx(2 - 1/x + x)))

Differentiate the sum term by term and factor out constants:

= d/dx((d/dx(2) - d/dx(1/x) + d/dx(x)))

The derivative of 2 is zero:

= d/dx(0 - d/dx(1/x) + d/dx(x))

Use the power rule, d/dx(x^n) = n x^(n - 1), where n = -1.

d/dx(1/x) = d/dx(x^(-1)) = -x^(-2):

= d/dx(0 - -1/x^2 + d/dx(x))

The derivative of x is 1:

= d/dx(0 - -1/x^2 + 1)

Differentiate the sum term by term:

= d/dx(1) + d/dx(1/x^2)

The derivative of 1 is zero:

= d/dx(1/x^2) + 0

Simplify the expression:

= d/dx(1/x^2)

Use the power rule, d/dx(x^n) = n x^(n - 1), where n = -2.

d/dx(1/x^2) = d/dx(x^(-2)) = -2 x^(-3):

Answer: A, C, D

Step-by-step explanation:

1) AD=BD must be true because the angle bisector drawn from the vertex angle of an isosceles triangle is the perpendicular bisector of the base.

2) AC=CD does not need to be true because angles ADC and CAD do not need to be congruent.

3) This must be true by the definition of an angle bisector.

4) This must be true because angles CDA and CDB are both right angles.

5) This does not need to be true because triangle ADC does not need to be isosceles.

Answer:

x=9

y=[tex]9\sqrt{2}[/tex]

Step-by-step explanation:

This is a special type of triangle known as a 45-45-90 triangle.

The ratio for the sides of this triangle are x:x:x[tex]\sqrt{2}[/tex]

Meaning that the two sides other than the hypotenuse are equal, so in this triangle x=9 because it is not a hypotenuse.

The hypotenuse, however, is the value of one side multiplied by [tex]\sqrt{2}[/tex].

In this case it is 9, so 9*[tex]\sqrt{2}[/tex] = [tex]9\sqrt{2}[/tex]
