Answer:
60
Step-by-step explanation:
The mean of a set of numbers is calculated by adding them all together and then dividing the sum by the amount of values in the data set. In this scenario, we know the mean is 30, and there are 3 numbers in the data set, 10, 20, and an unknown number (x).
Let's set up an equation with the information we have.
30 = (10 + 20 + x) / 3
Now we can multiply both sides by 3 ==>
90 = 10 + 20 + x
Combine like terms ==>
90 = 30 + x
Subtract 30 from each side ==>
60 = x
And now you have your answer!
The value of x = 60 would make the mean of the data set 30.
what number has an opposite of 18 and an absolute value of 18
Answer:
-18
Step-by-step explanation:
By opposite, I believe this is talking about the sign. Note that taking an absolute value of a number always results in a positive number.
|-18| = 18
Answer:
-18, 18
Step-by-step explanation:
Opposite means negative becomes positive, and positive becomes negative. Absolute value is distance from zero. It is 18 away from zero. Opposite of 18 is -18.
What is the end behavior of the graph?
Answer:
As [tex]x[/tex] approaches infinity [tex]f(x)[/tex] approaches negative infinity.
Step-by-step explanation:
As you can see in the graph as [tex]x[/tex] grows larger in the negative direction, the [tex]y[/tex] increases in the negative direction too.
Thus:
[tex]\lim_{x \to -\infty} f(x) = -\infty[/tex]

Which of the following statements about the expected value of a random experiment is true? A. The expected value is the value you will get after one trial. B. The expected value is the average of the values after 100 trials. C. As the number of trials gets larger, the average of the trials approaches the expected value. D. The expected value never actually equals the average of the trials. Please select the best answer from the choices provided A B C D
Answer: C. As the number of trials gets larger, the average of the trials approaches the expected value
Step-by-step explanation:
The expected value is the weighted average of the results of an experiment. As more trials go on, the actual average is more likely to get closer to the expected value. The expected value can be explained as the theoretical result after infinity trials, so as the number of trials approaches infinity, the result will approach the expected value.

To find the surface area of a rectangular prism, we can use the following formula:
[tex]SA=2(lw+lh+wh)[/tex]
l = lengthw = widthh = heightSolving the QuestionWe're given:
l = 4 yardsw = 1 yardh = 3 yardsPlug the given measurements into the formula for surface area:
[tex]SA=2(lw+lh+wh)\\SA=2[(4)(1)+(4)(3)+(1)(3)]\\SA=2(4+12+3)\\SA=2(19)\\SA=38[/tex]

Step-by-step explanation:
Corresponding angles of similar figures are congruent.
Angles with vertex of same order number are corresponding.
m∠U = m∠C = 97°m∠V = m∠D = 124°m∠T =m∠B = 102°Answer:
m∠U =97°
m∠V = 124°
m∠T = 102°
Step-by-step explanation:
As TUVWX ~ BCDEF then the corresponding interior angles are the same.
Therefore:
m∠T = m∠B = 102°
m∠U = m∠C = 97°
m∠V = m∠D = 124°
m∠W = m∠E = 101°
m∠X = m∠F = 116°

What is a cylinder?A cylinder is a three-dimensional structure formed by two parallel circular bases connected by a curving surface. The circular bases' centres overlap each other to form a right cylinder.
Given the radius of the cylinder is 5 inches, while the height is 16 inches, therefore, the volume of the cylinder will be,
Volume of the cylinder = πr²h = π×(5)²×16 = 1,256.637 in³ ≈ 1,256 in³
Hence, the volume of the cylinder with a radius of 5 inches and a height of 16 inches is 1256 in³.

The gravitational force ona abody falling towards the earthb is directly proportional to the mass of the body the gravitiaional force on the body js 2 kg is 19.6 newtons
A. Write a direct variation equation relating the mass x and the gravitational force y on the falling body
B. Using your equation from 4.a find the gravitaional force of an object with the mass of 5kg
Don't RIP OFF OR I WILL REPORT
Answer:
A. y = 9.8xB. 49 NewtonsStep-by-step explanation:
Direct proportional relationship formula
y = kx, where y- dependent variable, x- independent variable, k- coefficient of proportionalityGiven values
x = 2 kgy = 19.6 NFind the value of k using the formula
19.6 = 2kk = 19.6/2k = 9.8Part AThe equation for this case is
y = 9.8xPart BFind the value of y when x = 5
y = 9.8*5 = 49 NAnswer:
A. y = 9.8x
B. 49 newtons
Step-by-step explanation:
Part A
Definition of the given variables:
x = mass in kgy = gravitational force in newtonsIf the gravitational force is directly proportional to the mass, then:
[tex]y \propto x \implies y=kx \quad \textsf{(for some constant k)}[/tex]
Given:
x = 2 kgy = 19.6 newtonsSubstitute the given values into the equation and solve for k:
[tex]\implies 19.6=2k[/tex]
[tex]\implies k = 9.8[/tex]
Therefore, the direct variation equation is: [tex]y=9.8x[/tex]
Part B
To find the gravitational force of an object with mass of 5 kg, substitute x = 5 into the found equation from part A and solve for y:
[tex]\implies y=9.8(5)[/tex]
[tex]\implies y=49\:\: \sf newtons[/tex]

Which of the following is a polygon?
A shape can only be classified as a polygon if:
(1) There must be no curves in the shape.(2) The shape is not opened. It has to be closed.(3) The sides of the shape must not intersect each other.Option A
We can see that the figure is opened. Therefore, the shape is not a polygon. According to (2), to classify a shape, a polygon, the shape must not be opened.
Therefore, this shape is not a polygon.
Option B
This shape is a polygon because it has no curves, it is not opened, and the sides of the shape are not forming an intersection.
Therefore, this shape is a polygon.
Option C
This figure has a side length intersecting another side length. Therefore, this figure is not a polygon. According to (3), to classify a shape, a polygon, the sides of the shape must not intersect each other.
Therefore, this shape is not a polygon.
Option D
This figure is not a polygon because a side length of the figure is curved. According to (1), To classify a shape, a polygon, there must be no curves in the shape.
Therefore, this shape is not a polygon.
Hence, Option B is correct.
