The height of a cylinder is twice the radius of its base. A cylinder has a height of 2 x and a radius of x. What expression repr

cluponka [151]

<h2>Answer:</h2><h2>volume of the cylinder = 2π $x^{3}$ </h2>

Step-by-step explanation:

The height of a cylinder is twice the radius of its base.

Let the height of the cylinder = 2x

Let the radius of the cylinder = x

By formula, volume of the cylinder = π $r^{2}$ h

here r = x, h = 2x

substituting the values in the equation, we get

volume of the cylinder = π $r^{2}$ h = π $x^{2}$ (2x)

volume of the cylinder = 2π $x^{3}$

You'd like to estimate the proportion of the 12,152 full-time undergraduate students at a university who are foreign students.

Minchanka [31]

Answer:

a) The data distribution consists of ( 7 )1's (denoting a foreign student) and ( 43 )0's (denoting a student from the U.S.).

b) The population distribution consists of the x-values of the population of 12,152 full-time undergraduate students at theuniversity, ( 6 )% of which are 1's (denoting a foreign student) and ( 94 )% of which are 0's (denoting a student from the U.S.).

c) The mean is ( 0.06 )

The standard deviation is ( 0.0336 )

The sampling distribution represents the probability distribution of the ( sample ) proportion of foreign students in a random sample of ( 50 ) students. In this case, the sampling distribution is approximately normal with a mean of ( 0.06 ) and a standard deviation of ( 0.0336 )

A city determines that a planned community must have at least 4 acres of developed and open space, and the difference

FinnZ [79.3K]

Answer:

The graph in the attached figure

Step-by-step explanation:

Let

x -----> the number of open acres

y ----> the number of developed acres

we know that

$x+y \geq 4$ -----> inequality A

$x\leq 1$ ----> inequality B

Remember that

if the number of open acres, x, can be no more than 1. then the number of open acres, x must be less than or equal to 1

Solve the system of equations by graphing

The solution is the shaded area (Note The number of acres cannot be a negative number)
