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.
Answer:
1) The value of x= 0.0642
2)
Step-by-step explanation:
1) Given : A right angle triangle with sides x and 10 and angle is 50°
To find : Value of x
Solution : Since, it is a right angle triangle
Therefore, we apply
Where Base = x, Hypotenuse= 10, angle = 50°
The value of x= 0.0642
2) Given :
To find : Value of
Solution : We have given
so, B= 7 , H=25
By Pythagoras theorem,
Now, P=24, B=7, H=25
