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:
28
Step-by-step explanation:
If 50% of students are boys that means there are 30 boys and 30 girls. Then if 30% of boys are 10 and 60% of girls are 18. You add 18+10 and that gives you 28.
Answer:
93.60 would be the last price while
23.4 would be the subtracted price
Step-by-step explanation:
20 percent move the decimal over 2 places to the right and get 0.2
then multiply 117 by 0.2 and get the last answer
Answer:
x = 0
Step-by-step explanation:
Given sin(3π/2+x) + sin(3π/2+x) = -2
2sin(3π/2+x) = -2
sin(3π/2+x) = -1
clearly x = 0 on satisfies the above equation
We know that sin(3π/2+x) = - cosx
-cosx = -1
cosx = 1 Has only one solution at x=0 in x∈ [0,2π)
