Below is a regression analysis of the number of burglaries in 2006 (response variable) on the student enrollment (explanatory variable) for 17 randomly-selected four-year public universities in the United States. Assume that the conditions for regression inference have been satistied.
Predictor Coef SE Coef T P
Constant 4.43 10.41 0.43 0.677
Enrollment 0.0018751 0.0005724 3.28 0.005
S= 22.5012 R-Sq= 41.7% R-Sq (adj ) =37.8%
Which of the following is an appropriate interpretation of the number 22.5012?
(a) The standard deviation of the response variable "student enrollment" is 22.5012.
(b) The standard deviation of th explanatory variable "number of burglaries" is 22.5012. )
(c) The typical distance between observed values for student enrollment and values for enrollment predicted by the regression equation is about 22.5012.
(d) The typical distance between observed values for number of burglaries and values for number of burglaries predicted by the regression equation is about 22.5012.
(e) The sum of the squared deviations between the observed number of burglaries and the number of burglaries predicted by the regression equation is about 22.5012

Answer:

a) 90°

b) 90° - 35° = 55°

c) 65° - 40° = 25°

d) 90° - 65° = 25°

e) 180° - 65° = 115°

f) 180° - 35° = 145°

g) 180° - 40° = 140°

h) 65° + 35° = 100°

180° - 100° = 80°

i) 90° - 40° = 50°

j) 35° + 40° = 75°

180° - 75° = 105°

Answer:

  20 = 2 + (7 -4) × 6

Step-by-step explanation:

The Order of Operations requires the parentheses be evaluated first, then the multiplication performed. Finally, the addition is performed.

If each of the blanks is filled with a single digit, the result of the multiplication must be a composite number greater than 10. Those are 12, 14, 15, 16, 18, 20. For the expression shown above, we have chosen to make the product be 18. That means the first blank is filled with 2 and the remaining blanks must evaluate to one of the products 2×9 or 3×6.

We have chosen 6 for the last blank, so the two blanks in parentheses must have a difference of 3. The digits 2 and 6 cannot be used, leaving possible choices as (3-0), (4-1), (7-4), (8-5).

Our final expression is chosen to be ...

  20 = 2 +(7 -4)×6

Real number and Irrational number

Step-by-step explanation:

Given

[tex]-\sqrt{ 20[/tex]

Required

The set it belongs to

First, solve the expression

[tex]-\sqrt{ 20} = -4.472136[/tex]

The above number is not an integer and it is not whole or natural because it has decimal points

It is not a rational number because it cannot be expressed as a simple fraction

However, the number can be categorized as either irrational or real because of the level of the decimal point in the result

Answer:

=5

Step-by-step explanation:

perimeter= 2(L)+2(W)

11 =2(1/2)+2W

11=1+2W

11-1=2W

10=2W

Both sides divided by 2

therefore The width is 5

Answer:

315 yd cubed

Step-by-step explanation:

To find the volume of the pyramid, we first need to consult the equation below. Thebase is for the rectangular portion, then after multiplied by the height it is divided by 3 to get the pyramid.

[tex]\frac{1}{3} (B * H )[/tex]

To get the base, we multiply the length by the width.

21 * 9 = 189

189 * 5 = 945

945 divided by 3 = 315

Answer:

Let's find the base area:

21 x 9 = 189

Now let's multiply the base area by the height:

189 x 5 = 945

Now let's divide by 3( x 1/3 ):

945 divided by 3(x 1/3) = 315 yd^3 is your answer

Step-by-step explanation:

Formula area of a rectangular Pyramid(just like any other pyramid):

BH x 1/3

To find base we multiply length by width just using the basic formula of finding area of a rectangle.

Then we multiply our base area by our height.

One we've done that we now divide by 3(multiplying by 1/3)

Answer:

The radius is 6 cm rounded

Step-by-step explanation:

[tex]C[/tex] stands for circumference

[tex]r[/tex] stands for radius

here's the formula to find the radius:  [tex]r=\frac{C}{2\pi }[/tex]

[tex]r=\frac{36}{6.283}[/tex]

[tex]r=5.729[/tex]

Hope this helps

Answer:

r = 18/pi or approximately 5.732484076 cm

Step-by-step explanation:

The circumference of a circle is given by

C = 2 * pi *r

36 = 2*pi*r

Divide each side by 2 pi

36 / (2pi) = 2pi r/ (2pi)

18/ pi = r

Using 3.14 for pi

18/ 3.14 = r

5.732484076 = r

Answer:

[tex] y = \frac {4}{3}x - 2[/tex]

Step-by-step explanation:

Given the following data;

Points on the line (x1, y1) = (3, 2)

Slope, m = 4/3

To write the equation in slope intercept form;

First of all, we would determine the intercept of the line.

Equation of straight line is y = mx + c

Where;

m is the slope.

x and y are the points

c is the intercept.

Substituting the values in order to find the intercept, we have;

2 = 4/3(3) + c

2 = 4 + c

c = 2 - 4

c = -2

Therefore, the equation of line is y = 4/3x - 2

[tex] y = \frac {4}{3}x - 2[/tex]

C = 13

The total cost will be $13.00

Rock Climbing Word Problem

Trina: 5 + 3.25h = 21.25

Now, subtract 5 from both sides.

3.25h = 16.25

Now, divide both sides by 3.25.

h = 5

Trina spent 5 hours at the facility.

Ralph: 21.25 - 5/ 3.25 = h

Subtract 5 from 21.25

16.25/ 3.25 = h

Now divide

5 = h

Ralph will spend 5 hours at the facility to spend the same amount as Trina.

I hope I helped you in time! Good Luck!!

Answer:

A sample of 801 is needed.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the z-score that has a p-value of [tex]1 - \frac{\alpha}{2}[/tex].

The margin of error is of:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

95% confidence level

So [tex]\alpha = 0.05[/tex], z is the value of Z that has a p-value of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].

25% of U.S. homes have a direct satellite television receiver.

This means that [tex]\pi = 0.25[/tex]

How large a sample is necessary to estimate the true population of homes which do with 95% confidence and within 3 percentage points?

This is n for which M = 0.03. So

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]0.03 = 1.96\sqrt{\frac{0.25*0.75}{n}}[/tex]

[tex]0.03\sqrt{n} = 1.96\sqrt{0.25*0.75}[/tex]

[tex]\sqrt{n} = \frac{1.96\sqrt{0.25*0.75}}{0.03}[/tex]

[tex](\sqrt{n})^2 = (\frac{1.96\sqrt{0.25*0.75}}{0.03})^2[/tex]

[tex]n = 800.3[/tex]

Step-by-step explanation:

According To Question

(Diagram, Please Find In Attachment)

Question 38 . Cos ∅ = 12/13   ∅ in Quadrant-4(Where only Cos & Sec are Positive all other Functions Are Negative in this Quadrant)

Now ∅ Represent a Right Angle Triangle with Base=12 Perpendicular=5 & Hypothenese=13

Sin∅ = -5/13 , Cosec∅=-13/5 , Tan∅=-5/12 , Cot∅=-12/5 & Sec∅=13/12

Question 39 . SinX=-3/4   X Lies in Quadrant-3(Where only Tan & Cot are Positive all other Functions Are Negative in this Quadrant)

Find By Using Basic Formulas

[tex]SinX^{2}+CosX^{2}=1[/tex] ↔ Put Value of Sin∅=-3/4

We get CosX= ±[tex]\frac{\sqrt{5} }{4}[/tex] (but X Lies in Quadrant-3 Where Cosine Is Negative , So Neglect CosX= +[tex]\frac{\sqrt{5} }{4}[/tex])

So CosX= -[tex]\frac{\sqrt{5} }{4}[/tex] ...... now you get the point . All Questions Will Solve like This .

It seems you havent posted a graph

Answer:

[tex]x=47^{\circ}[/tex]

Step-by-step explanation:

By definition, parallelograms have two pairs of parallel sides. Therefore, AD and BC are parallel, and the angles marked with [tex]x[/tex] and [tex]47^{\circ}[/tex] are alternate interior angles. Since alternate interior angles are equal, we have [tex]x=\boxed{47^{\circ}}[/tex]

The underlying vector field,

F(x, y) = -y/(4x ² + 9y ²) i + x/(4x ² + 9y ²) j,

is conservative, so any integral of F over a closed path is 0.

To establish that F is conservative, we want to find a scalar function f(x, y) whose gradient is equal to F(x, y), which entails solving

[tex]\dfrac{\partial f}{\partial x}=-\dfrac y{4x^2+9y^2}[/tex]

[tex]\dfrac{\partial f}{\partial y}=\dfrac x{4x^2+9y^2}[/tex]

Integrating the first equation with respect to x yields

[tex]f(x,y)=-\dfrac16\arctan\left(\dfrac{2x}{3y}\right)+g(y)[/tex]

and differentiating with respect to y gives

[tex]\dfrac x{4x^2+9y^2}=\dfrac x{4x^2+9y^2}+\dfrac{\mathrm dg}{\mathrm dy} \implies \dfrac{\mathrm dg}{\mathrm dy}=0 \implies g(y)=C[/tex]

Step-by-step explanation:

P(red) = 12/(12+10+5+4+29)

= 1/5

= 0.2

= 20%

Answer:mean means to average. in order to average, add all the numbers then divide by how many numbers you have.

All these ages add up to 150. because there are 7 ages, divide by 7. this is 21.4 which can be rounded to about 21

46 + 48 + 21 + 12 + 15 + 8 = 150

150 ÷ 7= 21.4285 = 21
