Answer:
Option B) Y - estimated average predicted value, X – predictor, Y-intercept (), slope ()
Step-by-step explanation:
In the simple linear regression model estimate is given by:
Comparing this regression line with the slope intercept form, we get:
where m is the slope of the straight line and c is the y-intercept that is the value of y when x is zero.
here,
Y is the predicted variable or the variable we need to predict
X is the predictor or the variable that helps us to predict Y
is the slope of the regression line.
is the y-intercept or the value of y when x is zero.
Thus, Option B)
Y - estimated average predicted value, X – predictor, Y-intercept (), slope ()
Answer:
I. and II. are correct
Step-by-step explanation:
The line y=0 is a horizontal asymptote in both directions, so ...
The function value f(0) is 0, so the limit is the same from either direction:
__
The expression for statement III can be simplified:
The limit of this is 0 from either direction, so the limit does exist at x=1.
_____
We consider that ...
both statements I. and II. are correct.
Answer:
36 cm.
Step-by-step explanation:
Let, the side of the square = x cm.
As, side of the square is 3 cm less than and 2 cm more than the sides of the rectangle.
Thus, the sides of the rectangle will be (x+3) and (x-2)
<em>Also, it is given that, 'The area of the square is 30 cm² less than the area of the rectangle'.</em>
As, Area of the square =
Area of the rectangle =
Thus, we have
i.e.
i.e.
i.e.
Thus, the side of the square is 36 cm.
