Step-by-step explanation:
Average Rate of Change:
Step 1: Define variables
f(b) = 5
f(a) = 3
b = 2
a = 1
Step 2: Plug into formula
(5 - 3)/(2 - 1)
2/1

Answer:
3240 degrees.
Step-by-step explanation:
Here (as you said), this 20-gon is convex. In the image below, that is #1. One interior angle is 162 degrees. Simply multiply that by 20 to get 3240 degrees as the sum.
Answer:
And the best option would be:
a. ŷ= 37.643-1.0543x
Step-by-step explanation:
We assume that the data is this one:
x: 34.0, 32.5, 35.0, 31.0, 30.0, 27.5, 29.0
y: 1.30, 3.25, 0.65, 6.50, 5.85, 8.45, 6.50
Find the least-squares line appropriate for this data.
For this case we need to calculate the slope with the following formula:
Where:
So we can find the sums like this:
With these we can find the sums:
And the slope would be:
Nowe we can find the means for x and y like this:
And we can find the intercept using this:
So the line would be given by:
And the best option would be:
a. ŷ= 37.643-1.0543x
