Find the median of the following data : 9, 15, 17, 18,6, 20, 8, 5, 18, 18, 10, 5, 14, 12, 10, 7

Answer:
The median of the data is 12.
Step-by-step explanation:
The median is really just another word for the average. To find that, you add all of the numbers and divide that sum by the number of numbers there are.
9+15+17+18+6+20+8+5+18+18+10+5+14+12+10+7=192
There are 16 numbers in this data set. So, we will divide the sum by 16.
192÷16=12
I hope this helps!! :)
Answer:
5x-2
Step-by-step explanation:
Since f(x)-g(x) you take 3x+2 and subtract -2x-4.
3x+2+2x-4
5x-2
Answer:
Step-by-step explanation:
Suppose the dimensions of the playground are x and y.
The total amount of the fence used is given and it is 780 ft. In terms of x and y this would be 3x+2y=780 (we add 3x because we want it to be cut in the middle). Therefore, y= 780/2-3/2x. Now, the total area (A )to be fenced is
A=x*y= x*(390-3/2x)=-3/2 x^2+390x
Calculating the derivative of A and setting it equals to 0 to find the maximum
A'= -3x+390=0
This yields x=130.
Therefore y=780/2-3/2*130=195
Thus, the maximum area is 130*195=25,350ft^2

Well its was really simple your welcome
Answer:
Step-by-step explanation:
Given: 
To solve this equation, we need to isolate 
on one side of the equation algebraically. I see that we have like terms, but they are on opposite sides of the equal sign. Let's add 
to both sides.
To isolate x, divide both sides by 7.
