how do you find the volume of spheres?

Answer:

   x degree = 112 degree

Step-by-step explanation:

let the intersecting point of two cords be O.

then arc QR = angle QOR

which means ; 68 degree = angle QOR

 Now,

angle QOR + angle POQ = 180 degree ( linear pair )

or,  68 degree + angle POQ = 180 degree

hence, angle POQ = 112 degree,.

Answer:

27π

Step-by-step explanation:

A = πr²

  = π(6)²

   =36π

You want 3/4 of the circle

(3/4) 36π = 27π

Answer:

135 units square

Step-by-step explanation:

The area of a parallelogram is calculated by multplying height and base

The height of the given shape is 15 units and the base is 9 units

15 × 9 = 135 units square.

Get 180, then subtract every angle you see in the diagram and you'll get your answer.

Answer:

a = 25

Step-by-step explanation:

The exterior angles of a polygon sum to 360°

Sum the exterior angles and equate to 360

a + a + 40 + 51 + 55 + 54 + 2a + 60 = 360, that is

4a + 260 = 360 ( subtract 260 from both sides )

4a = 100 ( divide both sides by 4 )

a = 25

Answer:

[tex]c \: (x + 5)(x - 1)[/tex]

Answer:

C) 1

Step-by-step explanation:

Slope = change in y over change in x

In the graph shown as y goes up 1 x goes up 1

so slope = 1/1 or 1

The slope equation is y=mx+b.

b is where the line crosses on the y axis, also known as the y-intercept.

m is the slope, which you are trying to find.

y and x are the points on the graph.

The slope is 3/3, which can be turned into 1, so the answer is c.

Answer:

z^2 = -12y

or y = -(z^2/12)

Step-by-step explanation:

Answer:

z^2 = -12y

Step-by-step explanation:

Given the vertex at origin;

This is same as (0,0)

The focus (0,-3)

The general form is;

(z-h)^2 = 4p(y-k)

(h,k) is the vertex (0,0); so h = 0 and k = 0

The focus is given as;

(h,k + p)

so ;

k + p = -3

but k =0

so p = -3

Thus, the equation of the parabola is;

(z-0)^2 = 4(-3)(y-0)

z^2 = -12y

Answer:

32 dollars

Step-by-step explanation:

I think the answer is $32 because 14-12 is 2 and if you multiply 16 times 2 that's how I got the answer. I could be wrong I am sorry if I am.

Answer:

Answer is D) 42x − 24

Step-by-step explanation:

Opening the expression given in question

6(7x − 4)

6 will be multiplied by both items present inside parenthesis.

it can be written as

={(6 * 7x) - (6*4)}

=42x-24

Hope that clears the question.

A. Y ≤ 4.

Step-by-step explanation:

This  opens downwards and has a maximum  at f(x) = 4.

Given:

The regression equation is:

[tex]y=-25x+436[/tex]

The given point is (17,3.8).

To find:

The residual for the given point.

Solution:

We have,

[tex]y=-25x+436[/tex]

Substituting [tex]x=17[/tex], we get

[tex]y=-25(17)+436[/tex]

[tex]y=-425+436[/tex]

[tex]y=11[/tex]

The predicted value at [tex]x=17[/tex] is 11.

The given point is (17,3.8). It means the observed value at [tex]x=17[/tex] is 3.8.

Formula for residual:

Residual = Observed value - Predicted value

Residual = [tex]3.8-11[/tex]

Residual = [tex]-7.2[/tex]

Therefore, the residual for the given point is -7.2.

Answer:

The mean absolute deviation of a dataset is the average distance between each data point and the mean. It gives us an idea about the variability in a dataset. ... Step 2: Calculate how far away each data point is from the mean using positive distances.

Mean deviation is defined as how much is each element of the data is far away from the mean of the data.

We can define the mean of the given data set as the average of all the numbers. Mathematically, we can write mean as -

M = ∑x{i}/n

Given is to discuss what does the value of mean absolute deviation tell about the spread of the data.

Mean deviation is defined as how much is each element of the data is far away from the mean of the data. Mathematically, we can write mean deviation as -

[tex]$\frac {1}{n} \sum \limits_{i=1}^n |x_i-m(X)|[/tex]

where -

Therefore, Mean deviation is defined as how much is each element of the data is far away from the mean of the data.
