The mean you have to add up your numbers first then divide them by the amount of numbers you have .ex. 1+2+3 is 6 then divide so 6÷3 =3 Median is the middle number in list. So put them in order then muddle number is your median. If you have two numbers left add them and divide by 2. That will be your median.

Mean: The "average" number; found by adding all data points and dividing by the number of data points.
Example: The mean of 4, 1, & 7 is (4+1+7)/3 = 12/3= 4
Median: The middle number; found by ordering all data points and picking out the one in the middle (or if there are two middle numbers, taking the mean of those two numbers).
Example: The median of 4, 1, & 7 is 4 bc when the numbers are put in order (1, 4, 7), the number 4 is in the middle.

What is the degree of 12x4 - 8x + 4x2 - 3? A. 8 B. 4 C. 3 D. 12

Soloha48 [4]

In this problem, we are asked to determine the degree of the given expression 12X4 - 8X + 4X2 -3. To answer this, first, we need to arrange the mathematical expression in descending order with respect to its power such as the new arrangement will become 12x4 + 4x2 -8x -3. The degree is clearly visible and it is 4. Therefore, the answer to this problem is the letter "B" which is 4.

If f(x)=3x and g(x)=1/x, what is the domain of (g o f)(x)?

Neko [114]

Here it is given that f(x)=3x and g(x)=1/x

We have to find the domain of (g o f)(x)

Now it is given that f(x) = 3x

and it is also given that g(x) = 1/x

so (g o f)(x) = g( f(x) ) = g( 3x )

which comes out to be 1 / 3x

The domain of the expression is all the real numbers except where the expression is undefined so the domain of the given expression is all real numbers except 0.
