Answer:

in a group of numbers (2,4,7,9,7,5,7,8,3)

The mean would be 5.2

The mode would be 7

The median would be 7

Explanation:

Say we have a group of numbers (2,4,7,9,7,5,7,8,3)

Lets start by finding the Median! *Remember, the median is the MIDDLE!

So, if the median is the middle, it would be 7.

Lets do the mode now. *Remember the mode is the one that happens the MOST!*

If we take a look at the numbers, we see that 7 occurs the most (it appears 3 times)

Our mode would be 7.

Lastly, lets do the mean. *You add and divide for the mean*

So, we start by adding all of the numbers together.

Basically, ( 2 + 4 + 7 + 9 + 7 + 5 + 7 + 8 + 3) you then get 52.

Next, we divide 52 by all the numbers that we added together (9)

And we get our mean: 5.2

What’s the circumference, to this problem ?

Dafna11 [192]

Answer:

The formula to get the circumference of a circle is $C=2*\pi * r$ but in this case we see that a diameter is being used therefore we can get rid of the 2 and the r because that is what the diameter and just replace d into there like this $C=d*\pi$ .

We can then input the value and we get that $C=1*\pi$ which then just narrows down to $C=3.142$ .

Hope this helps! Let me know if you have any questions

What is the value of pie and how can I round it to the nearest tenth

Orlov [11]

The Value of Pi is actually an infinite number and cannot be calculated. It is not a real number. Usually many just shorten Pi to the decimal 3.14, which it is most commonly used as since there is no exact decimal of Pi.

Finding the slope from points

nekit [7.7K]

Answer:

m = -3

Step-by-step explanation:

The formula to find the slope of the line is :

slope = m = $\frac{y_1 - y_2}{x_1-x_2}$

Given that the two coordinates of the line are :

( -1 , - 7 ) ⇒ ( x₁ , y₁ )

( 1 , -13 ) ⇒ ( x₂ , y₂ )

Let us solve now.

m = ( y₁ - y₂ ) ÷ ( x₁ - x₂ )

m = ( -7 - ( -13)) ÷ ( -1 - 1 )

m = ( -7 + 13 ) ÷ ( -2 )

m = 6 ÷ -2

m = -3
