Nothing is mentioned...how am I supposed to help you?
4 big mice and 3 small mice because 4 X 25=100; 3 X 10=30
100+30=130
is that right?
Given:
The data points are:
(1, 0), (2, 3), (3,1), (4,4), (5,5)
To find:
The equation of best fit line in the form of
and then find the value of b.
Solution:
The general form of best fit line is:
...(i)
Where, m is the slope of best fit line and b is the y-intercept of the line.
Using the graphing calculator, we get the equation for the best fit line and the equation is
...(ii)
On comparing (i) and (ii), we get

Therefore, the value of b is equal to -0.7.
Answer: 2/7
Both 44 and 154 have the greatest common factor of 22.
44/22 = 2
154/22 = 7
