Statistics Question. Use the Desmos graphing calculator to find the least-squares regression line for the dataset in the table:
1 answer:
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.

Given that,
In <u>triangle TPQ, </u>
- RS || PQ,
- RS = 3 cm,
- PQ = 6 cm,
- ar(∆ TRS) = 15 sq. cm
As it is given that, <u>RS || PQ</u>
So, it means
⇛∠TRS = ∠TPQ [ Corresponding angles ]
⇛ ∠TSR = ∠TPQ [ Corresponding angles ]
<u>Now, We know </u>
Area Ratio Theorem,
This theorem states that :- The ratio of the area of two similar triangles is equal to the ratio of the squares of corresponding sides.
