The percent decrease on a TV after the markdown to the nearest tenth​ is 23.6%.

The percent decrease formula can be expressed as:

Percent decrease = [( original value - new value ) / original value ] × 100%

Given the data in the question:

The original value of the TV = $550

New value after markdown  = $420

Percent decrease =?

Plug the given values into the above formula and solve for the percent decrease.

Percent decrease = [( original value - new value ) / original value ] × 100%

Percent decrease = [( 550 - 420 ) / 550 ] × 100%

Percent decrease = [ 130 / 550 ] × 100%

Percent decrease = 0.2363 × 100%

Percent decrease = 23.6%

Therefore, the percent decrease is 23.6%.

Regarding the violation of multicollinearity, which of the following description is wrong?

a. It changes the intercept of the regression line.

b. It changes the sign of the slope.

c. It changes the slope of the regression line.

d. It changes the value of F-tests.

e. It changes the value of T-tests

Answer:

a. It changes the intercept of the regression line

Step-by-step explanation:

Multicollinearity is a term used in multiple regression analysis to show a high correlation between independent variables of a study.

Since it deals with independent variables correlation, it means it must be found before getting the regression equation.

Now, looking at the options, the one that doesn't relate with multicollinearity is option A because the intercept of the regression line is the value of y that is predicted when x is 0. Meanwhile, multicollinearity from definition above does in no way change the intercept of the regression line because it doesn't predict the y-value when x is zero.

Answer:

19[tex]\pi[/tex] + 76 mm

Step-by-step explanation:

First, use the circumference formula to find the perimeter of the entire circle:

c = 2[tex]\pi[/tex]r

c = 2[tex]\pi[/tex](38)

c = 76[tex]\pi[/tex]

Divide this by 4, since the question asks for the perimeter of the quarter circle:

76[tex]\pi[/tex]/4

= 19[tex]\pi[/tex]

19[tex]\pi[/tex] is the arc length section of the perimeter. The length of the other 2 sides of the perimeter, formed by the radius, can be found by doubling 38.

38(2) = 76

Add this to 19[tex]\pi[/tex]:

19[tex]\pi[/tex] + 76

So, the expression is 19[tex]\pi[/tex] + 76 mm

Step-by-step explanation:

Let

[tex]y_1=4x^2-c^2[/tex]

[tex]y_2=c^2-4x^2[/tex]

We have to find the value of c such that the are of the region bounded by the parabolas =32/3

[tex]y_1=y_2[/tex]

[tex]4x^2-c^2=c^2-4x^2[/tex]

[tex]4x^2+4x^2=c^2+c^2[/tex]

[tex]8x^2=2c^2[/tex]

[tex]x^2=c^2/4[/tex]

[tex]x=\pm \frac{c}{2}[/tex]

Now, the area bounded by two curves

[tex]A=\int_{a}^{b}(y_2-y_1)dx[/tex]

[tex]A=\int_{-c/2}^{c/2}(c^2-4x^2-4x^2+c^2)dx[/tex]

[tex]\frac{32}{3}=\int_{-c/2}^{c/2}(2c^2-8x^2)dx[/tex]

[tex]\frac{32}{3}=2\int_{-c/2}^{c/2}(c^2-4x^2)dx[/tex]

[tex]\frac{32}{3}=2[c^2x-\frac{4}{3}x^3]^{c/2}_{-c/2}[/tex]

[tex]\frac{32}{3}=2(c^2(c/2+c/2)-4/3(c^3/8+c^3/28))[/tex]

[tex]\frac{32}{3}=2(c^3-\frac{4}{3}(\frac{c^3}{4}))[/tex]

[tex]\frac{32}{3}=2(c^3-\frac{c^3}{3})[/tex]

[tex]\frac{32}{3}=2(\frac{2}{3}c^3)[/tex]

[tex]c^3=\frac{32\times 3}{4\times 3}[/tex]

Answer:

$182.00

Step-by-step explanation:

We know that Matt will work for 13 hours, and that he will earn 14.00 an hour. We are asked how much Matt will earn by the end of the week. Because Matt's earnings are not based on his brother's earnings, we can disregard how much his brother makes.

We add 14.00 13 times, as Matt earns 14 dollars for each hour and he works for 13 dollars. This is equal to multiplying 14 by 13, resulting in 14 * 13 = 182 as our answer

Answer:

Step-by-step explanation:

a) For payments made at the beginning of the period, the annuity is called an "annuity due." The formula in the first attachment tells how to compute the payment for a given present value ($500,000), number of periods (N=10), and interest rate (i=0.08).

  pmt = $500,000/(1 +(1 -(1 +i)^(-N+1))/i) = $500,000/(1 +(1 -(1.08^-9))/.08)

  pmt ≈ $68,995.13 . . . . annual payment

__

b) After the first payment, the account balance is ...

  $500,000 -68,995.13 = $431,004.87

After subsequent payments, the account balance will be ...

  $431,004.87×1.08 -68,995.13 = $396,490.13 . . . after 2nd payment

  $396,490.13×1.08 -68,995.13 = $359,214.21 . . . after 3rd payment

The payment amount that can be made in perpetuity is the amount of the monthly interest on this balance:

  X = $359,214.21 × (0.08/12) = $2394.76

Answer:

  loaf: $0.90; roll: $0.15

Step-by-step explanation:

Let b and r represent the cost of a loaf of bread and a roll, respectively.

The two purchases can be written in equation form as ...

  b +6r = 1.80

  2b +4r = 2.40

__

The usual ways to work problems like this are "substitution" or "elimination". The latter is sometimes called "addition."

The way these equations are written, we can see that it is relatively easy to write an expression for b from the first equation:

  b = 1.80 -6r

Substituting that into the second equation, we get ...

  2(1.80 -6r) +4r = 2.40

  3.60 -8r = 2.40 . . . . . . . collect terms

  1.20 = 8r . . . . . . . . . . add 8r-2.40

  0.15 = r . . . . . . . . . divide by 8

Then substituting this into the expression for b, we have ...

  b = 1.80 -6r = 1.80 -6(0.15) = 0.90

One loaf costs $0.90; one roll costs $0.15.

__

The idea with "elimination" is to combine the equations in such a way that one of the variables is eliminated in the process. Here, there are several ways that can be done.

We recognize that the b-coefficient in the second equation is double that in the first equation. So, we can subtract the second equation from double the first equation to make the b-terms disappear.

  2(b +6r) -(2b +4r) = 2(1.80) -(2.40)

  8r = 1.20 . . . . . . . simplify

  r = 0.15 . . . . . . . divide by 8

Using the first equation, we can find b:

  b + 6(0.15) = 1.80

  b = 0.90 . . . . . . . . . subtract 0.90

One loaf costs $0.90; one roll costs $0.15.

__

Another way we can eliminate one of the variables is to rewrite the second equation without its excess factor of 2:

  b +2r = 1.20

Then subtracting the first equation from 3 times this will eliminate the r variable:

  3(b +2r) -(b +6r) = 3(1.20) -(1.80)

  2b = 1.80 . . . . . . . . . simplify

  b = 0.90

Then, using the above version of the second equation, we have ...

  0.90 +2r = 1.20

  2r = 0.30

  r = 0.15

One loaf costs $0.90; one roll costs $0.15.

To find:

The points on the graph at the function value [tex]f(x)=3[/tex].

Solution:

We have,

[tex]f(x)=\dfrac{5-x}{x^2+5x+6}[/tex]

Substituting [tex]f(x)=3[/tex], we get

[tex]3=\dfrac{5-x}{x^2+5x+6}[/tex]

[tex]3(x^2+5x+6)=5-x[/tex]

[tex]3x^2+15x+18=5-x[/tex]

Moving all the terms on one side, we get

[tex]3x^2+15x+18-5+x=0[/tex]

[tex]3x^2+16x+13=0[/tex]

Splitting the middle term, we get

[tex]3x^2+3x+13x+13=0[/tex]

[tex]3x(x+1)+13(x+1)=0[/tex]

[tex](3x+13)(x+1)=0[/tex]

Using zero product property, we get

[tex](3x+13)=0\text{ or }(x+1)=0[/tex]
