The radius of the Ferris wheel is shown. Which is the circumference of the Ferris wheel, rounded to the nearest foot?

A ferris wheel. The radius of the ferris wheel (from the center of the wheel to its edge) is labeled 125 feet.

Answers

Answer:

The circumference is around 785 feet

Step-by-step explanation:

The circumference of a circle is pi x radius x 2 or pi x diameter.

If the Ferris wheel's radius is 125, then this is what you do:

pi x 125 x 2

= pi x 250

= 3.14 x 250

= 785

Answer:

About 785.4

Step-by-step explanation:

C = 2pir

R = 125

2*pi*125 ≈ 785.4

C ≈ 785.4

A baseball has a diameter of 3.7 inches. Find the volume of the baseball. Round the answer to the nearest tenth. Use 3.14 for pi.
The volume of the baseball is about ____ in3.

Answers

Answer:

Volume is about 26.5 in^3

Step-by-step explanation:

The volume = 4/3 pi r^3   where r = the radius.

the radius = 1/2 diameter =  1/2 * 3.7  = 1.85 ins.

So V = 4/3 * 3.14 * 1.85^3

= 26.5084

Consider the following statement: Two sets of data with the same mean will also have the same variability. Do you agree or disagree with this statement? Explain.


Answers

disagree because most of the times statistical questions or mainly yes or no questions and never really in the middle. that’s because it can throw off it’s variability! i hope i helped ❤️

The statement is false and same mean can have different variability

What is Mean?

The mean value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values.

Mean = Sum of Values / Number of Values

Given data ,

Let the mean of the data be represented as M

Now , The mean is a measure of central tendency that represents the average value of a set of data, but it does not provide information about the variability or spread of the data.

For example, consider the following two sets of data:

Set 1: 1, 2, 3, 4, 5 (mean = 3)

Set 2: 0, 2, 3, 4, 6 (mean = 3)

Both sets have the same mean of 3, but Set 1 has a smaller range (4) compared to Set 2 (6). The range is a measure of variability that represents the difference between the maximum and minimum values in a set of data.

Hence , two sets of data with the same mean can have different variability,

What is PEDMAS Rule?

PEDMAS rule states that the order of operation starts with the parentheses first or the calculation which is enclosed in brackets. Then the operation is performed on exponents(degree or square roots) and later we do operations on division & multiplication and at last addition and subtraction.

Given

8+23×5

We have to perform multiplication as per the PEDMAS rule

= 8 + 115

Now we have to perform addition

= 123

Hence, value of 8+23×5 is 123.

Mk, i don’t know if this is hundred percent correct. Alright so, first add 12 and 16. Those two numbers equal 28. Every triangle equals 180, so if you subtract 28 from 180 that equals 156. The missing X is 156! Sorry if the explanation is kinda bad. My english isn’t very good. Also, if you need your answer to be rounded to the nearest tenth, it will be 160. Hope this helps!

Answers

Answer:

65 mph

Step-by-step explanation:

To find the unit rate (miles per hour), we can use the equation

[tex]r=\frac{d}{t}[/tex]

Where

r=rate (miles per hour)

d=distance (in miles)

t=time (in hours)

Using the given information, we can plug in

[tex]d=97\frac{1}{2}[/tex]

[tex]t=\frac{3}{2}[/tex]

So, our equation is

[tex]r=\frac{97.5}{1.5}[/tex]

When we divide 97.5 and 1.5, we get

[tex]65[/tex]

So,

[tex]r=65[/tex]

In conclusion, the rate (miles per hour) is 65 mph.
