What Is Calculating The Mean

What is calculating the mean

 

Answer:

Mean, also known as the average, is calculated just by using two operations - addition and division. First, add all the numbers in the given data set then divide the sum by the number of digits found in the data set.

Example #1:

Given: 12, 9, 5, 6

Add the numbers

12 + 9 + 5 + 6 = 32

Divide the sum by 4 (since there were 4 given)

32/4 = 8

The mean/average is 8.

Example #2:

Given: 10, 12, 11

The given is 3 digits.

Tip: If the number of the given digits is odd, you can easily get the mean by arranging the numbers from smallest to largest or ascending order then getting the middle number since it would be the average. The result will be the same as to adding and dividing.

Ascending Order: 10, 11, 12

Mean (middle number) = 11

Checking:

10 + 11 + 12 = 33

33/3 = 11

The mean is 11.

What Do You Call The Given Equations?

What do you call the given equations?   Polynomial Equation:         A polynomial equation is any polynomial equated to zero. Examples: x - 2 = 0 x² + 2x + 5 = 0 5x + 1 = 0 x³  - 2x² - 4x + 8 = 0 x(x - 4) = 0 Number of Roots: The number of root(s) of the polynomial equation is based on the highest degree of the exponent it contain. Example #1: x - 2 = 0 the number of root(s) is just 1 since it is a polynomial of the first degree. Example #2: x² + 2x + 5 = 0 the number of root(s) is 2 since it is a polynomial of the second degree. Example #3: 5x + 1 = 0, there is only 1 root because it is a polynomial equation of the first degree. Example #4: x³  - 2x² - 4x + 8 = 0 have 3 roots since its highest degree is 3. Example #5: x(x - 4) = 0 have 2 roots because it is a polynomial equation of the second degree.

Fill In With Your Answers: A Personal Goal That I Have Already Achieved

Fill in with your answers: A personal goal that I have already achieved   Answer: Overcoming my shyness Ive been actually very shy before due to some things Ive experienced when I was a kid. I cant talk to people that Im not close for long. I cant look at their eye. I avoid talking to people unless really necessary. I dont like to be noticed. But now, Im slowly regaining confidence to talk to people. I dont feel that shy anymore when people talk to me/notice me which is really a huge accomplishment for me. I know that this is an activity/assignment because I have also answered this before so Im gonna list out more goals that you would have most likely to have achieved. graduated primary/elementary school winning in a contest overcame your fear/s made an extreme challenge #BrainlySummerChallenge
