2×5^{2} if you don't understand its 2 times 5 to the second power.
Answer:
a.the goodness of fit for the estimated multiple regression equation increases.
Step-by-step explanation:
As the value of the multiple coefficient of determination increases,
a. the goodness of fit for the estimated multiple regression equation increases.
As we know that the coefficient of determination measures the variability of response variable with the help of regressor. As we know that if the value of the coefficient of determination increases strength of fit also increases.
The right answer is Option A.
Step-by-step explanation:
Given,
Heart rate goal = I
Heart rate reserve = H
70% of H = 
Resting heart rate = R
According to given statement,
70% of heart rate reserved is added to resting heart rate to calculate heart rate goal, therefore,
I = R + 0.7H
I=R+0.7H represents the given situation.
The right answer is Option A.

Answer:
x=-61
Step-by-step explanation:
Answer:
undefined
Step-by-step explanation:
f(x) = 2/ (-5x-10)
Let x = -2
f(-2) = 2/ (-5(-2)-10)
=2/(10-10)
=2/0
= undefined
