The relation between area, height and volume is: volume = area * height

In this question we need to find the relation between area height and volume.

the formula for area and volume are based on height:

volume = base area * height

Let v represents the volume, A represents area and h represents the height.

V = A * h

As we know the volume of rectangular prism is:

volume = length * width * height

i.e., V = l * w * h

and the base area is:

area = length * width

i.e., A = l * w

Substitute A =  l * w in V = l * w * h

Then we get, V = A * h

Therefore, the relation between area, height and volume is: V = A * h i.e., volume = area * height

The relationship between the volume of a sphere and the volume of a cylinder is: the volume of a sphere is 2/3 of the volume of a cylinder with same radius, and height equal to the diameter.

In this question we need to describe the relationship of the volume between the volume of a sphere and the volume of a cylinder.

Consider  a cylinder with radius r and height h.

we know that the formula for the volume of cylinder is,

V1 = π * r² * h

Consider a sphere with radius r1.

We know that the formula for the volume of sphere is,

V2 = 4/3 * π * r1³

If the sphere and a cylinder have same radii and height of cylinder equal to the diameter then, r1 = r and h = 2r

V2 = 4/3 * π * r³

And V1 = π * r² * (2r)

V1 = 2 * π * r³

V1 = 2 * 3/4 * V2

V1 = 3/2 * V2

volume of cylinder = 3/2 *  volume of sphere

Therefore, the volume of a sphere = 2/3 * the volume of a cylinder

Harry's soccer team needs 168 people to attend their pancake breakfast in order to raise $2,520.

To find the number of people that need to attend the pancake breakfast, we can set up the following equation:

Number of People x Cost per Person = Total Cost

We know that the total cost is $2,520 and the cost per person is $15, so we can substitute those values into the equation:

Number of People x $15 = $2,520

We can solve for the number of people by dividing both sides of the equation by $15:

Number of People = $2,520 / $15

This gives us the number of people that need to attend the pancake breakfast in order to raise the desired amount of money. In this case, the number of people is 168.

Therefore, Harry's soccer team needs 168 people to attend their pancake breakfast in order to raise $2,520.

The margin of error is 0.086 and its C.I is (0.575 , 0.785).

What is margin of error?

n = 117 , x =87

Point estimate for the proportion:

P = x/n

= 81/118

= 0.68644

Confidence = 95%, α = 0.05

From z-table area 0.975 close to z=1.96

Margin of error, E = 1.96 √((0.68*0.55)/130)

= 1.96 * 0.05363

= 0.105

= 0.086

Confidence = P ± E

= 0.68 ± 0.105

=(0.68-0.105 , 0.68+0.105)

Solving for two variables (normally denoted as "x" and "y") requires two sets of equations.

Assuming you have two equations, the best way for solving for both variables is to use the substitution method, which involves solving for one variable as far as possible, then plugging it back in to the other equation. Knowing how to solve a system of equations with two variables is important for several areas, including trying to find the coordinate for points on a graph.

Write out the two equations that have the two variables you want to solve. For this example, we will find the value for "x" and "y" in the two equations "3x + y = 2" and "x + 5y = 20"

Solve for one of the variables in on one of the equations. For this example, let's solve for "y" in the first equation. Subtract 3x from each side to get "y = 2 - 3x"

Plug in the y value found from the first equation in to the second equation in order to find the x value. In the previous example, this means the second equation becomes "x + 5(2- 3x) = 20"

Solve for x. The example equation becomes "x + 10 - 15x = 20," which is then "-14 x + 10 = 20." Subtract 10 from each side, divide by 14 and you have end up with x = -10/14, which simplifies to x = -5/7.

Plug in the x value in to the first equation to find out the y value. y = 2 - 3(-5/7) becomes 2 + 15/7, which is 29/7.

Check your work by plugging in the x and y values in to both of the equations.

In the equation c(n) = 50+4n, the value of c(7) is equal to 78.

Absolutely one element of Y is assigned to every element of X in a mathematical function from a set X to a set Y. Both the set X and the set Y are referred to as the function's domain and codomain, respectively.

Al-Biruni and Sharaf al-Din al-Tusi were two Persian mathematicians who developed the earliest known approach to function and its concept. The basic conception of functions was the relationship between fluctuating quantities and other variables. An illustration of this is how time affects a planet's position. In the past, the idea was developed with the infinitesimal calculus around the end of the 17th century, and, until the 19th century, the functions that were considered were differentiable.

This is how the function is defined:

The equation c(n) = 50+4n defines function c, and n is the number of visits.

The function displays the cost in USD per month.

Thus, the following formula can be used to get the value of c(7):

c(7) = 50+4n

c(7) = 50+4(7)

= 50+28

=78

Therefore, c(7)=78

AD = BC = 8 ( opposite sides of a parallelogram are congruent )

DC = AB = 15 ( opposite sides of a parallelogram are congruent )

Consecutive angles in a parallelogram are supplementary , sum to 180° , so

∠ A + ∠ D  = 180° , that is

∠ A + 68° = 180° ( subtract 68° from both sides )

∠ A = 112°

∠ B = ∠ D = 68° , and

∠ C = ∠ A = 112°

In mathematics and statistics, the mean is the average of a set of variables. The simple arithmetic mean (add the numbers and divide the total by the number of observations), geometric mean, and harmonic mean are all ways for calculating the mean. The mean (average) of a data set is computed by adding all of the numbers in the set and dividing by the number of values in the set. When arranging data from smallest to greatest, the median is the value in the middle. The mode is the most commonly occurring number in a data set.
