Hello there.
Linear regression is a useful tool that allows calculating approximate values for a function that passes through given points(with the best error possible). It is very useful in science to make an estimation of the comportment of movement, electricity and some decays.
For example, I will relate a case in a physics lab: We calculated the positions of a car in an air rail and the times. With this information, I was able to make a linear regression to calculate the Position function for that case.
Answer:
x=-10
Step-by-step explanation:
15x+8=-2+14x
15x-14x=-2-8
x=-10
I might not be understanding what you mean but I think it is by counting 10s. 170,180,190,200,210,220,230,240,250,260,270,280,290,300,310,320,330,410.
The perimeter of a rectangular field is 364 yards. If the width of the field is 84 yards, what is its length?
(364 : 2) - 84 =
182 - 84 =
98
I believe it is the first figure
