Answer:

The correct answer is "16.987, 20213".

Step-by-step explanation:

Given that,

[tex]n=30[/tex]

[tex]\bar x=18.6[/tex]

[tex]s = 5.2[/tex]

[tex]df=30-1[/tex]

   [tex]=29[/tex]

[tex]\alpha = 0.10[/tex]

By using the table, the critical values of t will be:

= [tex]\pm 1.699[/tex]

Now,

The confidence interval will be:

= [tex]\bar x \pm \frac{t\times s}{\sqrt{n} }[/tex]

By putting the values, we get

= [tex]18.6 \pm \frac{1.699\times 5.2}{\sqrt{30} }[/tex]

= [tex]16.987,20.213[/tex]

Answer: (5,3)

Step-by-step explanation:

y=x^2-10x+28

Complete the square.

y=(x-5)^2+3

Use the vertex form, y=a(x-h)^2+k to find the values of a, h, and k.

a=1

h=5

k=3

Find the vertex (h, k).

Answer:

52 pi centimeters cubed

Step-by-step explanation:

volume of a cylinder = πr^2h

Volume of a cone 1/3(πr^2h)

π = 22/7

r = radius  

The volume of a cone is one-third that of a cylinder

volume of cone = 156/3 = 52

Answer:

The maximum is at (1,3)

Step-by-step explanation:

The maximum value of the function is at the vertex

The maximum is at (1,3)

Max value of the given function = 3

Answer:

The volume is:

[tex]V_{2}=9984\: ft^{3}[/tex]

Step-by-step explanation:

The equation of the volume of a rectangular prism is:

[tex]V=L*W*H[/tex]

Where:

We know the volume is 768 ft³ and the new width change a 13 factor, in other words, W(2) = 13W(1), so we can divide each equation of the volume to find the new volume.

[tex]\frac{V_{1}}{V_{2}}=\frac{L*W*H}{L*W*13H}[/tex]

[tex]\frac{768}{V_{2}}=\frac{L*W*H}{L*W*13H}[/tex]

L and W remain constant.

Therefore, we just need to solve it for V(2).

[tex]\frac{768}{V_{2}}=\frac{1}{13}[/tex]

[tex]V_{2}=13*768=9984\: ft^{3}[/tex]

Answer:

I'm not sure what you are looking for but I'm assuming you are finding r.

r is equal to 4.

Step-by-step explanation:

6 = r + 2

In order to find r, you have to subtract 2 from 6.

So, r = 6 - 2 = 4

Answer:

[tex](x-1)^2+(y-6)^2=16[/tex]

Step-by-step explanation:

The equation of a circle is given by [tex](x-h)^2+(y-k)^2=r^2[/tex], where [tex](h,k)[/tex] is the center of the circle and [tex]r[/tex] is the radius of the circle.

From the diagram, we can find the following:

Thus, we have:

[tex](x-1)^2+(y-6)^2=4^2,\\\boxed{(x-1)^2+(y-6)^2=16}[/tex]

Answer:

(x-1)^2 + (y-6)^2 = 16

Step-by-step explanation:

center = (1,6)

radius = 4

equation of a circle (x-h)^2+(y-k)^2=r^2

(x-1)^2 + (y-6)^2 = 16

Answer:

1051 or..

10.51

Step-by-step explanation:

Since 33=30 and 0.1081 is supposed to be as a percentage since its already a  decimal you could just round it and make it into a fraction then once you get the answer to the fraction it would either be 1081 since 0.1081 as a fraction is 1081/10000 or you could make into 10.81 as a decimal but after that you subtract "30 - 1,081" or 10.81 -30" either one of them and each of those numbers would give you the same exact number. Answer: 1051 or as a decimal 10.51

Answer:

The correct answer 6.4 on PLATO edmentum

Step-by-step explanation:

I did the test

[tex]\frac{2}{x}[/tex]

[tex]\frac{x}{2}[/tex]

[tex]\frac{4x^4}{y^3}[/tex]

a. 2x^-3 • 4x^2

To solve this using only positive exponents, follow these steps:

i. Rewrite the expression in a clearer form

2x⁻³ . 4x²

ii. The position of the term with negative exponent is changed from denominator to numerator or numerator to denominator depending on its initial position. If it is at the numerator, it is moved to the denominator. If otherwise it is at the denominator, it is moved to the numerator. When this is done, the negative exponent is changed to positive.

In our case, the first term has a negative exponent and it is at the numerator. We therefore move it to the denominator and change the negative exponent to  positive as follows;

[tex]\frac{1}{2x^3} . 4x^2[/tex]

iii. We then solve the result as follows;

[tex]\frac{1}{2x^3} . 4x^2[/tex] = [tex]\frac{2}{x}[/tex]

Therefore, 2x⁻³ . 4x² = [tex]\frac{2}{x}[/tex]

b. 2x^4 • 4x^-3

i. Rewrite as follows;

2x⁴ . 4x⁻³

ii. The second term has a negative exponent, therefore swap its position and change the negative exponent to a positive one.

[tex]2x^4 . \frac{1}{4x^3}[/tex]

iii. Now solve by cancelling out common terms in the numerator and denominator. So we have;

[tex]\frac{x}{2}[/tex]

Therefore, 2x⁴ . 4x⁻³ = [tex]\frac{x}{2}[/tex]

c. 2x^3y^-3 • 2x

i. Rewrite as follows;

2x³y⁻³ . 2x

ii. Change position of terms with negative exponents;

[tex]2x^3.\frac{1}{y^3} .2x[/tex]

iii. Now solve;

[tex]\frac{4x^4}{y^3}[/tex]

Therefore, 2x³y⁻³ . 2x = [tex]\frac{4x^4}{y^3}[/tex]

Answer:

it was is face than surface I am 7th grade and doing the problem for class.

Step-by-step explanation:

If I am to late I am so sorry but for the next person that needs it.

(ﾉ◕ヮ◕)ﾉ*:･you can do it✧

For bases of solid figures, a lateral face is to a polygon what a lateral surface is to a circle.

The base of a solid figure is one of its faces that has been distinguished from the others in some way. The solid figure is usually oriented so that the base is situated at the bottom.

A pyramid is a three-dimensional figure with only one base. The base can be any polygon. The other faces are triangles. A pyramid is named according to the shape of its base.
