Answer:
∠ABD = 45°
Step-by-step explanation:
Since ABCD is a square, its diagonals (Line BD) bisect the angles of the corners of the square (∠ABC) into two equal angles (∠ABD and ∠CBD). The angle of each corner is 90° so you can find ∠ABD.
2(∠ABD) = 90°
∠ABD = 90° ÷ 2
∠ABD = 45°
-1 -2 -4 it on the y axixs to
Answer:
<h2>0.7</h2>
Step-by-step explanation:
The coefficient of determination which is also known as the R² value is expressed as shown;

Sum of square of total (SST)= sum of square of error (SSE )+ sum of square of regression (SSR)
Given SSE = 60 and SSR = 140
SST = 60 + 140
SST = 200
Since R² = SSR/SST
R² = 140/200
R² = 0.7
Hence, the coefficient of determination is 0.7. Note that the coefficient of determination always lies between 0 and 1.
