I need help with this question please

According to the question,

We are asked to calculate it’s circumference in terms of π.

★ Circumference of circle = 2πr

___________________________________

Let us first calculate the radius of the circle.

→ Diameter = 2 × Radius

→ 16 in = 2r

→ r = 16 in ÷ 2

→ r = 8 in

___________________________________

Substituting values in the formula of circumference,

→ C = 2πr

→ C = (2 × π × 8) in

→ C = 16π in

Therefore, 16π inches is the required answer.

The variables on a scatter plot are related using the equation of a straight line graph; y = mx + c.

Since the options are unclear, I will try to help you as much as possible. A scatter plot is an arrangement in which one variable is plotted on the vertical axis and another is plotted on the horizontal axis.

The variables on a scatter plot are related using the equation of a straight line graph; y = mx + c. Using this relation, we can establish the equation of the scatter plot.

Answer:

[tex]5.8[/tex]

Step-by-step explanation:

Similar shapes also maintain a constant proportion of sides. Therefore, we can set up the following equation:

[tex]\frac{31}{43}=\frac{\text{KI}}{8}[/tex]

Solving, we get:

[tex]\text{KI}=\frac{8\cdot 31}{43}\approx \boxed{5.8}[/tex]

Answer:

[tex]47x^3\sqrt{5x}[/tex]

Step-by-step explanation:

The objective is to combine the terms to make one radical, so therefore we know that we will have to take a [tex]\sqrt{5}[/tex] out of the second radical [tex]\sqrt{180}[/tex].

If we divide 180 by 5, we will get 36, so now we have

[tex]\sqrt{180}=\sqrt{5}[/tex]×[tex]\sqrt{36}[/tex]

[tex]\sqrt{36}[/tex] can be simplied into just 6.

So now the expression becomes

[tex]-\sqrt{5x^7}+8x^2*6 \sqrt{5x^3}[/tex]

Then we can further simplify by moving the [tex]x^{2}[/tex] into the radical to get two common terms with [tex]\sqrt{5x^7}[/tex].

[tex]x^{2} =\sqrt{x^4}[/tex], so we now have

[tex]-\sqrt{5x^7}+ 8\sqrt{x^4} *6 \sqrt{5x^3}[/tex]

So then we can combine the two radicals to get the expression to

[tex]-\sqrt{5x^7}+48\sqrt{5x^7}[/tex]

We now see that we have two terms with a common radical, and coefficients of -1, and 48.

That allows us to simplify further to

[tex]47\sqrt{5x^7}[/tex]

Here, we can take out [tex]\sqrt{x^6}[/tex], which is [tex]x^3[/tex], and get the final simplied form to be

[tex]47x^3\sqrt{5x}[/tex]

Answer:

230 in.²

Step-by-step explanation:

20 · 10 = 200 in.²

5 · 6 = 30 in.²

200 in.² + 30 in.²

Answer:

230 sq in

Step-by-step explanation:

You can find entire area (20 x 16) and subtract out the area of the missing piece (15 x 6)

20 x 16 = 320

15 x 6 = 90

320 - 90 = 230

Answer:

19.2

Step-by-step explanation:

khan

The expected count for the cell corresponding to east coast subscribers who responded "yes" is 19.2.

Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.

We need to first calculate the expected frequencies for each cell under the assumption that the null hypothesis of homogeneity is true.

The null hypothesis of homogeneity assumes that the proportion of internet subscribers satisfied with their internet speeds is the same on both the east and west coasts of the United States.

To calculate the expected frequencies, we can use the formula:

Expected frequency = (row total x column total) / grand total

For the cell corresponding to east coast subscribers who responded "yes":

Expected frequency = (row total for east coast x column total for "yes") / grand total

= (80 x 48) / 200

= 19.2

Therefore, the expected count for the cell corresponding to east coast subscribers who responded "yes" is 19.2.

Answer:

50

Step-by-step explanation:

The given equation is,

→ 3x/4 - (2x + 5)/3 = 5/2

→ 3x × 3 - 4(2x +5)/12 = 5/2

→ 9x - 8x -20/12 = 5/2

→ (x - 20)/12 = 5/2

→ x - 20 / 6 = 5

→ x - 20 = 30

→ x = 20 + 30

→ x = 50

Step-by-step explanation:

The volume of a cone is exactly the volume of a hemisphere, given that the radius and height are the same .

The height of the water in the cone = height of the hemisphere / height of cone ( given that the water completely fills the hemisphere )

∴ h  = 3 ( V / π r^2 )

Answer:

V = 3,367.6 cm³

Step-by-step explanation:

Diameter of sphere (D) = 18.6 cm

radius (r) = ½(18.6) = 9.3

π = 3.14

Formula for volume of a sphere = ⁴/3πr³

Plug in the values

V = ⁴/3 × 3.14 × 9.3³

V = ⁴/3 × 3.14 × 804.357

V = (4*3.14*804.357)/3

V = 3,367.57463

V = 3,367.6 cm³ (nearest tenth)
