Answer:

50.80 cm^3

Step-by-step explanation:

the polyhedron is a rectangular pyramid

Volume of a rectangular pyramid = 1/3 x ( width x height x length)

1/3 ( 4 x 5 x 3) = 20 inches

we need to convert inches to cm

1 in = 2.54 cm

20 x 2.54 = 50.80 cm^3

Answer:

131

Step-by-step explanation:

15/80 = x/700

80x = 10,500

x = 131.25

you cannot have 0.25 of a person so you must round down to the nearest integer

Step-by-step explanation:

Answer:

Population = number of children in gymnastic class = 5

Parameter = mean number of steps taken by the 5 children

Step-by-step explanation:

The population could simply be referred to as the total number or set of similar objects or subjects related to a certain study or research. In the scenario described above, the area of interest is a particular gymnastic class, therefore all individuals or children belonging to this particular gymnastic class makes up the population.

Parameter on the other hand are statistical metrics, values or calculations derived from the population figure or information. Here, the mean value of steps obtained from the step counts of the population data is called the parameter.

Population is number of children in gymnastic class = 5.

Parameter is mean number of steps taken by the 5 children.

Given that,

Suppose that there are 5 children in a gymnastics class.

One day, they count the number of steps each person takes while walking on their hands until they lose balance and come down.

The mean number of steps these children took while walking on their hands is 20 steps.

We have to Identify,

The population and parameter.

According to the question,

Parameters are descriptive measures of an entire population. However, their values are usually unknown because it is infeasible to measure an entire population. Because of this, you can take a random sample from the population to obtain parameter estimates.

The population could simply be referred to as the total number or set of similar objects or subjects related to a certain study or research.

The scenario described above, the area of interest is a particular gymnastic class, therefore all individuals or children belonging to this particular gymnastic class makes up the population.

Parameter on the other hand are statistical metrics, values or calculations derived from the population figure or information.

Here, the mean value of steps obtained from the step counts of the population data is called the parameter.

A parameter is a value that describes a characteristic of an entire population, such as the population mean.

The population mean and standard deviation are two common parameters.

Hence, Population = number of children in gymnastic class = 5.

Parameter = mean number of steps taken by the 5 children.

Answer:D

Step-by-step explanation:

The effect of the time of day a science class is taught on test scores being studied in an experiment will be the length of the class period. The correct option is D.

A test score is a piece of data, typically a number, that describes how well a test-taker performed. It is "a summary of the evidence contained in an examinee's replies to the test items that are connected to the construct or constructs being tested," according to one formal definition.

Given that the effect of the time of day a science class is taught on test scores is being studied in an experiment.

The time of the class periods is affected by the length of the class period. The length of the class period of one subject should be optimum so that students get the concepts easily without getting bored.

Therefore, an effect of the time of day a science class is taught on test scores being studied in an experiment will be the length of the class period. The correct option is D.

Answer:

D. 2,280 cm²

Step-by-step explanation:

Surface area of triangular prism = bh + (S1 + S2 + S3)*L

Where,

b = 24 cm

h = 10 cm

S1 = 26 cm

S2 = 24 cm

S3 = 10 cm

L = 34 cm

Plug in the values

Surface area = 24*10 + (26 + 24 + 10)*34

= 240 + 2,040

= 2,280 cm²

Answer: 21

Step-by-step explanation:

Ok so first of all the numbers in the parentheses go first.

So 6 to the power of 2 (6^2) would be 6x6 which equals 36

50-36=14

After that you just keep rewriting the problem after every step.

Since the 3 is outside of the parentheses, you would multiply it with the 14

3x14=42

Finally 42÷ 2=21

3x (50 - 6^2) ÷ 2 =

        3(14)÷ 2

           42÷ 2= 21

Hope this helps (:

It is close, but not exactly a right triangle.

If it were a right triangle, we would have ...

  21² +70² = 73²

We have instead ...

  441 +4900 ≠ 5329

Answer:

The values of x are +8 and -8

Step-by-step explanation:

1. The given equation is :

[tex]3x^2 - 192 = 0[/tex]

We need to find the value of x.

It can be done as follows :

[tex]x^2=\dfrac{192}{3}\\\\x^2=64\\\\x=\pm 8[/tex]

So, the values of x are +8 and -8.

Answer:

[tex]2\frac{3}{4}[/tex]

Step-by-step explanation:

Let's bring them to the same denominator: 4

[tex]2\frac{1}{4} = 2 + \frac{1}{4} = \frac{2\cdot 4}{4} + \frac{1}{4} = \frac{8}{4} + \frac{1}{4} = \frac{9}{4}\\~\\5 = \frac{5\cdot 4}{4} = \frac{20}{4}\\~\\5 - 2\frac{1}{4} = \frac{20}{4} - \frac{9}{4} = \frac{11}{4} = \frac{8}{4} + \frac{3}{4} = \frac{2\cdot 4}{4} + \frac{3}{4} = 2 + \frac{3}{4} = 2\frac{3}{4}[/tex]

Step-by-step explanation:

Answer:

[tex]h = \frac{v}{\pi r^{2} }[/tex]

Step-by-step explanation:

Answer:

x = 6.44 cm

Step-by-step explanation:

Given that,

Volume, V = 147π in³

Height, h = 9 cm = 3.54 in

We need to find the value of x. The formula of this polyhedron is given by :

[tex]V=\pi r^2 h\\\\r=\sqrt{\dfrac{V}{\pi h}} \\\\r=\sqrt{\dfrac{147\pi }{\pi \times 3.54}} \\\\r=6.44\ in[/tex]

or

r = 16.35 cm

So, the value of x is equal to 6.44 cm.

A circle is formed when a cone intersects a plane as shown in the drawing.

A circle is a shape consisting of all points in a plane that are given the same distance from a given point called the center.

A cross section is defined as the process where a surface is shown when a straight cut is made by something. We are given when a cone is intersected by a plane horizontally the shape of the cross - section is a circle .

When the cone is intersected vertically by a plane the shape of the cross- section will be a triangle. Hence the shape of the cross section depends according to the cut.

Cross section is usually used to find what is there inside the object.
