First of all, we have to know what median is.
Median- the middle number.
So we have to organize the numbers in roofer from least to greatest, so we have to count how many 2,3,4,5,6s there are and so fourth.
I’ll have them listed for you.
2 2 2 2 3 4 5 6 7 7 7 8 8 8 8 9 9 9 9 10 10 10 10 10 10.
Next step is to find the middle number (s). If it has an even amount of numbers, we have to take the two middle numbers and divided by two.
If there are an odd amount of numbers, we just pick the middle number.
[i.e: 2 3 4; the middle number here is 3]
[i.e: 2 3 4 5; the middle number is 3+4=7 divided by 2 which equals 3.5]
Okay so let’s count how many numbers there are.
There are 25 numbers in total, so therefore there are 2 middle number (s).
So let’s divided 25/2 to get the two middle numbers, which is 12.5, therefore numbers 12-13 are middle numbers.
So let’s count what number is 12 and 13. When you count the numbers in order, you can tell that 8 and 8 are numbers of 8.
The final step is to just calculate by adding both numbers and dividing by two because we are trying to find the middle number(average number).
8 + 8 = 16
16/2= 8
The median for this question is 8.

2x squared would be you final answer
Answers:
4; 20; 3x² - 4x + 3; 52; 17
Step-by-step explanation:
f(-1): replace x in f(x) = x² + 3 with -1: f(-1) = (-1)² + 3 = 4
f(-4) + g(-1) = (-4)² + 3 + <em>2(-1) + 3</em> = 16 + 3 <em>- 2 + 3</em> = 20 <em>(since g(x) = 2X + 3)</em>
<em />
3f(x) - 2g(x) = 3[x² +3] - 2[2x + 3} = 3x² + 9 - 4x - 6 = 3x² - 4x + 3
f(g(2)): First, evaluate g(2). It is g(2) = 2(2) + 3 = 7. Next, use this output, 7, as the input to f(x): f(g(x)) = (7)² + 3 = 49 + 3 = 52
g(f(2)): First, evaluate f(x) at x = 2: f(2) = (2)² + 3 = 7. Next, use this 7 as the input to g(x): g(f(2)) = g(7) = 2(7) + 3 = 17
Answer:
2x^3-23y^2+72-128
Step-by-step explanation:
its like when you just do two
do the first 2 first
(y-8)(y-8)
this is (y^2 -8y+y^2+16) simplify (2x^2-7y+16)
then add the other bracket
(2x^2-7y+16) (y-8)
2x^3-16x^2-7y^2+56y+16y-128 simplify
