I hope this helps you
this triangle is isosceles right triangle
base=height
Area=base×height /2
18=b×b/2
b^2=36
b=6
Given:
The table of values.
To find:
The least-squares regression line for the data set in the table by using the desmos graphing calculator.
Solution:
The general form of least-squares regression line is:
...(i)
Where, m is the slope and b is the y-intercept.
By using the desmos graphing calculator, we get

Substitute these values in (i).


Therefore, the correct option is A.
4 = 12
10 = 18
22 = 30
54 = 62
62 = 70
100 = 108
25/50 * 16/32
1/2 * 1/2
= 1/4
Answer:
11
Step-by-step explanation:
Replace the values of x and y into the equation.
2(4) + 3 = 8 + 3
= 11
