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:
1 and 5/6
Step-by-step explanation:
The reason why is I divided the numerator and denominator by 2 to reduce the fraction.
Answer: The radius of the ball is 7 meters.
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Surface area of a sphere: 4 π r^2
Replacing with the value given:
615.75 = 4 π r^2
Solving for r (radius):
615.75 /4π= r^2
√(615.75 /4π) =r
r = 6.99 = 7m (rounded)
The radius of the ball is 7 meters.
