Complete Question

A newsletter publisher believes that above 41% of their readers own a personal computer. Is there sufficient evidence at the 0.10 level to substantiate the publisher's claim?

State the null and alternative hypotheses for the above scenario.

Answer:

The null hypothesis is  [tex]H_o : p \le 0.411[/tex]

The  alternative hypothesis  is  [tex]H_a : \mu > 0.41[/tex]

Step-by-step explanation:

From the question we are told that

   The  proportion is  [tex]p = 0.41[/tex]

Generally the null hypothesis is  [tex]H_o : p \le 0.411[/tex]

The  above condition represents the  null hypothesis because it contains and equality in its condition

Answer:

[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{ {60.2 \: m}}}}}}[/tex]

Step-by-step explanation:

Given,

Area of rectangular piece of land ( l ) = 220 m²

Width ( w ) = 12.5 m

Finding length of the rectangular piece of land

[tex] \boxed{ \sf{area \: of \: rectangle = l \times w}}[/tex]

plug the values

⇒[tex] \sf{220 = l \times 12.5}[/tex]

Swap the sides of the equation

⇒[tex] \sf{12.5 \: l = 220}[/tex]

Divide both sides of the equation by 12.5

⇒[tex] \sf{ \frac{12.5 \: l}{12.5} = \frac{220}{12.5} }[/tex]

Calculate

⇒[tex] \sf{l = 17.6 \: m}[/tex]

Length of rectangular piece of land ( l )= 17.6 m

Finding perimeter of rectangular piece of land

[tex] \boxed{ \sf{perimeter \: of \: rectangle = 2(l + b)}}[/tex]

plug the values of length and breadth

⇒[tex] \sf{2(17.6 + 12.5) }[/tex]

Add the numbers

⇒[tex] \sf{2 \times 30.1}[/tex]

Multiply the numbers

⇒[tex] \sf{60.2 \: m}[/tex]

Therefore, Perimeter of rectangular piece of land is 60.2 m

Answer:

K = 4 ; N = 106

Step-by-step explanation:

Given the following :

Source of VARIATION - SS - df - - MS - - - - - F

Between groups - 1,959.79 - 3 - - 653.26 - 21.16*

Error - - - - - - - - 3,148.61 - - - - 102 - - 30.86

Total - - - - - - - - - - - 5,108.41 - 105

The degree of freedom between group (treatment) (DFT) is obtained using the formula ;

K - 1, where k = number of groups observed

DFT = K - 1 ; From the ANOVA table, DFT = 3

3 = K - 1

3 + 1 = K

K = 4

To obtain sample size (N) :

Degree of freedom of Error (DFE) is the difference between the sample size and the number of groups observed.

DFE = N - K ; From. The table DFE = 102 ; K = 4

102 = N - 4

102 + 4 = N

N = 106

Answer:

[tex] y = 178.3 ft [/tex]

Step-by-step explanation:

y is opposite to the reference angle, 27°.

350 ft is adjacent to the reference angle, therefore:

[tex] tan(27) = \frac{y}{350} [/tex]

Multiply both sides by 350

[tex] tan(27)*350 = \frac{y}{350}*350 [/tex]

[tex] tan(27)*350 = y [/tex]

[tex] 178.3 = y [/tex] (to nearest tenth)

[tex] y = 178.3 ft [/tex]

Answer:

No

Step-by-step explanation:

because the answer is 7

2x + 7 = 3x

2x + 7 - 7 = 3x - 7

2x = 3x - 7

2x - 3x = 3x - 7 - 3x

-x = -7

x = 7

Answer:

  see below

Step-by-step explanation:

You can attack this several ways. One is to work through f(g(x)) in each case and see if the result is x.

Another is to use a graphing calculator to evaluate y=f(g(x)) to see if the result is the line y=x.

Yet another way to work this is to pick a convenient value for x and evaluate f(g(x)) or g(f(x)). Here, we'll show this last case.

  A: f(1) = 2^0 +1 = 2; g(2) = log2(2-1) -1 = -1 . . . . g(f(1)) = -1, not 1 ⇒ not inverses

  B: f(2) = 1/2(ln(1) -1) = -1/2; g(-1/2) = 2e^(0) = 2 . . . g(f(2)) = 2 ⇒ inverses

  C: f(e) = 4ln(e^2)/e^2 = 8/e^2; g(8/e^2) = e^1 = e . . . g(f(e)) = e ⇒ inverses

  D: f(10) = 10^0-10 = -9; g(-9) = log(1) -10 = -10 . . . g(f(10)) = -10, not 10

      ⇒ not inverses

The second and third pairs of functions are inverses.

Answer:

The slope becomes 0.5625 and y intercept becomes 12.5.

$65.9375

Step-by-step explanation:

Given that

the total reimbursement function in terms of [tex]m[/tex] miles:

[tex]f(x) = 0.45m +5[/tex]

After the policy change, 5 more dollars are added and then total amount is multiplied by 1.25.

To find:

How to transform the graph of f.

Total reimbursement for a trip of 95 miles?

Solution:

[tex]f(x) = 0.45m +5[/tex] can also be written as:

[tex]y = 0.45m +5[/tex]

It is nothing but slope intercept form, comparing with [tex]Y = M X+ C[/tex]

M is the slope and C is the y intercept.

Slope of the graph is 0.45.

Y intercept is 5.

After change in the function, first of all add $5.

[tex]0.45m + 5+5 = 0.45m+10[/tex]

Now, multiply with 1.25

Resulting function becomes:

[tex]f(x) =1.25\times (0.45m+10)\\\Rightarrow f(x) =0.5625m+12.5[/tex]

Kindly refer to the attached image for the graph of the two functions.

Now, the slope becomes 0.5625 and y intercept becomes 12.5. This is the transformation.

To find the reimbursement for a trip of 95 miles:

Put m = 95

[tex]f(95) =0.5625\times 95+12.5 = \bold{\$65.9375 }[/tex]

Answer:

[tex]\huge\boxed{\text{next term}=4}\\\boxed{f(n)=4^{n-4}}[/tex]

Step-by-step explanation:

High school GPA is not a significant predictor of University GPA.

The Grade Point Average obtained at the end of high school education has almost nothing (in my opinion, it has nothing to do with) to do with grades that the scholar will obtain in college. Many scholars find it difficult adjusting to the social and academic life demands of tertiary institution.

A good predictor for university Grade Point Average would be:

The CGPA (Cumulative Grade Point Average) obtained by the student(s) in each year/session/level/part in the university.

This will be a significant predictor for university GPA.

The value of the flow rate in cubic feet per hour is 0.04.

The rate of the flow of the fluid is defined as the volume of the fluid flowing through the cross-section per unit of time. The unit of the flow rate is cubic feet per hour or cubic meter per hour etc.

Given that water flows through a pipe at a rate of 6300 liters every 8.5 months. Then the flow rate in cubic feet per hour will be calculated as below:-

1 litre = 0.0353 cubic feet

6300 litres = 6300 x 0.0353

6300 litres = 222.4 cubic feet

1 month = 730 hours

8.5 months = 6205 hours

The rate of flow in cubic per hour will be:-

Rate of flow = 222.4 / 6205 = 0.04 cubic feet per hour

Therefore, the value of the flow rate in cubic feet per hour is 0.04.

Answer:

There is no short answer.

Step-by-step explanation:

To find to intervals which f(x) increases or decreases, we first need to find it's derivative.

[tex]f(x) = sinx - cosx\\f'(x) = cosx - (-sinx) = cosx + sinx[/tex]

The function is increasing when it's value is  > 0 and decreasing when it's value is < 0.

If we take a look at this graph, cosx+sinx is positive when they are both positive or when cosx is greater then sinx on the negative part.

   The data is

P(X = x)    0.2 0.2 0.2   0.4  

 Generally the standard deviation is mathematically represented as

           [tex]\sigma = \sqrt{ \sum x^2 P(x) - (\sum x P(x))^2 }[/tex]

Here    [tex]x^2 = 1^2 \ \ 2^2 \ \ 3 ^2 \ \ 4^2[/tex]

    =>     [tex]x^2 = 1 \ \ 4 \ \ 9\ 16 \[/tex]

      [tex]\sum x^2 * P(x) = (1 * 0.2) + (4 * 0.2 ) + (9 * 0.2 ) + (16 * 0.2 )[/tex]

     [tex]\sum x^2 * P(x) = 9.4[/tex]

      [tex]\sum x P(x) = (1 *0.2) + (2*0.2) + (3 * 0.2) + (4 * 0.2)[/tex]

     [tex]\sum x P(x) = 2.8[/tex]

Slope= -4/3

Step-by-step explanation:

The points are (−3,−3) and (-9, 5)

Slope= gradient between the two points

Slope= (y2-y1)/(x2-x1)

Where y2= 5

Y1= -3

X2= -9

X1= -3

Slope= (y2-y1)/(x2-x1)

Slope= (5-(-3))/(-9-(-3))

Slope= (5+3)/(-9+3)

Slope= 8/-6

Slope= -4/3

Step-by-step explanation:

1). x² - 10x + a²

  By using the formula of (a - b)² = a² - 2ab + b²

  x² - 2(5)x + a²

  Therefore, for a perfect square of the expression a should be equal to 5.

  Therefore, (x² - 10x + 25) will be the answer.

2). x² + 2ax + 36

  = x² + 2(a)x + 6²

  For a perfect square of the given expression value of a should be 6.

   x² + 2(a)x + 6² = x² + 2(6)x + 6²

                           = (x + 6)²

  Therefore, x² + 12x + 36 will be the answer.

3). [tex]x^{2}+\frac{1}{2}x+a^2[/tex]

    [tex]x^{2}+2(\frac{1}{4})x+a^2[/tex]

   To make this expression a perfect square,

   a² = [tex](\frac{1}{4})^2[/tex]

   [tex]x^{2}+2(\frac{1}{4})x+(\frac{1}{4})^2[/tex] = [tex](x+\frac{1}{4})^2[/tex]
