The mean is also known as the average. Take the sum of all the numbers, and divide it by the amount of numbers you added together. Like this:
1+3+5+5+5+7+8+8=42
Now divide by 8 because there are 8 numbers.
42/8= 5.25.
Your average or mean is 5.25 or 5 1/4
5x-4=5x-15+11,soooo 5x-5x=-15+11+4 so the result is 0
121=11 81=9 its easy if u have a calculator

Divide through by a
The general form of a quadratic equation is:
By comparison, we have:
Sum is calculated as:
So, we have:
Divide both sides by -1
Similarly;
Product is calculated as:
So, we have:
Answer:
Step-by-step explanation:
The time intervals are [0.00, 0.10], [0.10, 0.30], and [0.30, 0.60].
The rate of change in each interval is the slope of the line between the endpoints:
m = [f(b) − f(a)] / (b − a)
Filling out the table:
The intervals are already in order from greatest to least. Simply reverse the order to get least to greatest:
[0.30, 0.60]
[0.10, 0.30]
[0.00, 0.10]
