Answer:
Rajini is correct, A = 1/2 × 9 × 7
Step-by-step explanation:
A = 1/2 × base × height
base = the leg bisected by the height, in this case leg QD = 9cm
height = 7cm in this case
Answer:
A line fitted to data points that minimizes the sum of the squared residuals
Step-by-step explanation:
The principle of least square(LS) consists of determining the values of the unknown parameters that will minimize the sum of squares of errors (or residuals) where errors are defined as the differences between observed values and the corresponding values predicted or estimated by the fitted model equation.
Thus, the correct definition of least square regression line is "<em>A line fitted to data points that minimizes the sum of the squared residuals</em>"
Answer:

Answer:
x=2 ; y=-5
Step-by-step explanation:
OP= 27. 6
Step-by-step explanatexplanation:
In triangle OPQ: Ô+P+Q =180
therefore <P= 6°
OQ= OP sinsinà
OP= OQ/ sinà
OP= 2.9/ sin6°
OP= 27.7 ft
using pythagoras
OP^2 = PQ^2 + OQ^2
PQ= sqrt( 27.74^2 - 2.9^2)
PQ= 27.27.6
