Slope, found using the points is -55/11 = -5
We use that for the equation y=mx+b where m=-5. Since we also know one of the points, we can plug that in and find b
-12=-5(4)+b
-12=-20+b
8=b
So the equation of the line is y=-5x+8
F(2)=4+10-8=6; f(6)=36+30-8=58. Average rate of change is (58-6)/(6-2)=52/4=13
Set the equal to each other
2x-4=4x-10
6=2x
x=3
y=2(3)-4
=6-4
y =2
Answer:
43.97
Step-by-step explanation:
just minus both the numbers but dont forget to put the percentage after the 55
Hello!
The mean is the average. To calculate it you add up all the numbers, and divide by how many numbers there were. So for example, if you had 1 and 3, you would add them and divide by two since there were two numbers. We will calculate the mean of this data set below.
(11+21+16+7+10)=65
65/5=13
The mean of the data set is 13.
---------------------------------------------------------------------------------------
Now we need to find the median. To do so we have to first order all of the numbers from least to greatest.
7,10,11,16,21
Now we have to find the number in the middle of the data set.
11 is our median. (Note that when calculating the median with an even number of data points, you will find the mean of the two center numbers)
I hope this helps!
