Complete question :

Cyber Monday Shopping A survey of 1000 U.S. adults found that 33% of people said that they would get no work done on Cyber Monday since they would spend all day shopping online. Find the 95% confidence interval of the true proportion.

Answer:

(0.301 ; 0.359)

Step-by-step explanation:

Sample size, n = 1000

Phat = 0.33

(1 - phat) = 1 - 0.33 = 0.67

Zcritical at 95% = 1.96

Confidence interval :

Phat ± margin of error

Margin of Error = Zcritical * sqrt[(phat(1 - phat)) /n]

Margin of Error = 1.96 * sqrt[(0.33 * 0.67) / 1000]

Margin of Error = 1.96 * 0.0148694

Margin of Error = 0.0291440

Lower boundary = (0.33 - 0.0291440) = 0.300856

Upper boundary = (0.33 + 0.0291440) = 0.359144

(0.301 ; 0.359)

Answer:

1. The volume of the cylinder is 263 [tex]cm^{3}[/tex].

2. The volume of the cylinder is 12 [tex]m^{3}[/tex].

3. The volume of the cylinder is 3165.1 [tex]cm^{3}[/tex].

4. The radius of the cylinder is 3.6 cm.

5a. Area of the base is 50.2 [tex]cm^{2}[/tex].

5b. The curved surface area of the pencil holder is 351.7 [tex]cm^{2}[/tex].

5c. The surface are of the pencil holder is 452.2 [tex]cm^{2}[/tex].

Step-by-step explanation:

1. The given shape is a cylinder, so that;

volume of a cylinder = [tex]\pi[/tex][tex]r^{2}[/tex]h

                                  = 3.14 x [tex](3.8)^{2}[/tex] x 5.8

                                  = 262.98128

The volume of the cylinder is 263 [tex]cm^{3}[/tex].

2. This is also a cylinder, but with a given diameter.

radius = [tex]\frac{diameter}{2}[/tex]

          = [tex]\frac{1.2}{2}[/tex] = 0.6 m

volume of a cylinder = [tex]\pi[/tex][tex]r^{2}[/tex]h

                                  = 3.14 x [tex](0.6)^{2}[/tex] x 10.6

                                  = 11.98224

The volume of the cylinder is 12 [tex]m^{3}[/tex].

3. volume of a cylinder = [tex]\pi[/tex][tex]r^{2}[/tex]h

                                      = 3.14 x [tex]6^{2}[/tex] x 28

                                      = 3165.12

The volume of the cylinder is 3165.1 [tex]cm^{3}[/tex].

4. volume of a cylinder = [tex]\pi[/tex][tex]r^{2}[/tex]h

239 = 3.14 x [tex]r^{2}[/tex] x 6

239 = 18.84 [tex]r^{2}[/tex]

[tex]r^{2}[/tex] = [tex]\frac{239}{18.84}[/tex]

   = 12.6858

r = [tex]\sqrt{12.6858}[/tex]

 = 3.5617

The radius of the cylinder is 3.6 cm.

5. Area of the base = [tex]\pi[/tex][tex]r^{2}[/tex]

radius = [tex]\frac{diameter}{2}[/tex]

           = [tex]\frac{8}{2}[/tex] = 4 cm

Area of the base = 3.14 x [tex]4^{2}[/tex]

                            = 50.24

Area of the base is 50.2 [tex]cm^{2}[/tex].

5b. Area of the curved surface of the pencil holder = 2[tex]\pi[/tex]rh

                                                                    = 2 x 3.14 x 4 x 14

                                                                     = 351.68

The curved surface area of the pencil holder is 351.7 [tex]cm^{2}[/tex].

5c. Surface area of the pencil holder = 2[tex]\pi[/tex]rh + 2[tex]\pi[/tex][tex]r^{2}[/tex]

                               = 2[tex]\pi[/tex]r(h + r)

                                = 2 x 3.14 x 4 (14 + 4)

                                = 452.16

The surface are of the pencil holder is 452.2 [tex]cm^{2}[/tex].

Answer: 490

Step-by-step explanation: If 7 out of ten students have a backback you can also say 7/10. If in total there are 700 students we can multiply 7/10 or .7 woth 700 and get the answer.  (7/10)(700)=490

Answer:

There mistake was on step three because 5 x 5 is 25 and the answer he got was 80.

Step-by-step explanation:

Answer:

56

Step-by-step explanation:

area of whole figure=

l×b

=20×10

=200

also,area of small fig.

=l×b

=18×8

=144

thus area of shaded part =a of whole- a of small

=200-144

=56

Answer and Step-by-step explanation:

To find the surface area, we have to find the area of all the faces of the shape, then add them together. We also only use the exposed faces, or the faces on the outside, not the inside.

Lets start with the rectangular prismed shape.

We have two faces with sides of 4 and 5, two faces with sides 16 and 4, and 1 side with 16 and 5.

Rectangles:

4 × 5 = 20

4 × 5 = 20

4 × 16 = 64

4 × 16 = 64

5 × 16 = 80

Now, let's do the triangles up top. There will essentially be 4 triangles, because we split them in half to find the area.

They have side lengths of 6 and 8.

Triangles:

6 × 8 = 48

6 × 8 = 48

6 × 8 = 48

6 × 8 = 48

Now, we have to the two rectangles up top.

They have side lengths of 10 and 4.

Top Rectangles:

10 × 4 = 40

10 × 4 = 40

Now, we add them all together.

20 + 20 + 64 + 64 + 80 + 48 + 48 + 48 + 48 + 40 + 40 =

40 + 208 + 192 + 80 =

520.

The Surface Area of the figure is 520 [tex]m^2[/tex]

Answer:

each interior angle = 150°

Step-by-step explanation:

(N x 180°) - 360° = the sum of interior angles

where N = the number of sides

(12 x 180°) - 360° = 1800°

Since it is a regular polygon, all 12 angles are equal:

1800°/12 = 150°

Answer:

Step-by-step explanation:

Solve this system using elimination by addition and subtraction:

Multiplying the second equation by -2 yields the modified system

8x - 2y = -4

-8x + 2y = +4

Adding these together, we get 0 + 0 = 0  (This is always true.)

There are an infinite number of solutions.

Answer:

$ 1267.

Step-by-step explanation:

Given :

David's monthly income after tax = $ 1430.15

His health insurance cost him in a month = $ 63

Percent deducted from his income after tax for his retirement option is = 7%

Therefore money left after retirement option deduction is :

$ 1430.15 - 7% of $ 1430.15

= 1430.15 - 100.11

= $ 1330.04

= $ 1330 (aprrox)

Money deducted from this amount for his health insurance plan

= $ 1330 - $ 63

= $ 1267

Therefore, David's monthly take home pay is $ 1267.

Answer:

A. The value of n can be any positive integer resulting in the same factor

Step-by-step explanation:

Given

[tex]x^2 + 2xn + n^2[/tex] --- the right expression

[tex]n > 0[/tex]

Required

Possible values of n

[tex]x^2 + 2xn + n^2[/tex]

Expand

[tex]x^2 + 2xn + n^2 = x^2 + xn+xn + n^2[/tex]

Factorize

[tex]x^2 + 2xn + n^2 = x(x + n)+n(x + n)[/tex]

Factor out [tex]x + n[/tex]

[tex]x^2 + 2xn + n^2 = (x + n)(x + n)[/tex]

From the expression above, we can see that the result has the same factor. This means that options (b), (d) and (e) are not possible

[tex]x^2 + 2xn + n^2 = (x + n)^2[/tex]

The above also shows that n can take any positive value.

Hence: (a) is correct

Answer:

y = 2/5x

Step-by-step explanation:

slope = 2-0/5-0 = 2/5

y - 2 = 2/5(x - 5)

y = 2/5x

Answer and Step-by-step explanation:

When we take a look at the graph, we can see that at around 1 gallon, which would be halfway between 0 and 2, the line is underneath $5.

That means we can eliminate any number that is or above $5.

That leaves us with answer choices A and C.

Let's go to a point that is easily readable. Point (4, 15) is readable, and we can use this to find the price per gallon.

Divide 15 by 4. We get 3.75 as the result.

This means that the answer choice is:

C. The cost of gas is $3.75 per gallon.

Answer:

x≥1

Step-by-step explanation:

Answer:

let the numbers be, x and x+1 ( as it is consecutive number the next number will have 1 more than the number )

sum = 41

so, x + ( x + 1 ) = 41

      x + x + 1 = 41

        2x + 1 = 41

             2x = 41 -1 = 40

              2x = 40

                x = 40/2 = 20

x = 20

x + 1 = 20 + 1 = 21

so the consecutive numbers whose sum is 40 are, 20 and 21
