Answer: The answer is 35 minutes.
Step-by-step explanation: Given that Gavin goes for a run at a constant pace of 9 minutes per mile and after 10 minutes, Lars started running along the same route, at a constant pace of 7 minutes per mile. We need to find the number of minutes Lars will take to reach Gavin.
In 9 minutes, distance run by Gavin = 1 mile.
So, in 1 minute, distance travelled by Gavin will be
Similarly,
In 7 minutes, distance run by Lars = 1 mile.
So, in 1 minute, distance travelled by Lars will be
Now, since Lars started after 10 minutes, so distance run by Gavin in those 10 minutes will be
Now, difference between Lars and Gavin's rate of runnings is
Therefore, the time taken by Lars to reach Gavin is given by
Thus, the required time is 365 minutes.
Answer:
b) y = 289.815 when
Step-by-step explanation:
We are given the following information in the question:
where y is the dependent variable,
are the independent variable.
The multiple regression equation is of the form:
where,
: is the intercept of the equation and is the value of dependent variable when all the independent variable are zero.
: It is the slope coefficient of the independent variable
.
: It is the slope coefficient of the independent variable
.
- The regression coefficient in multiple regression is the slope of the linear relationship between the dependent and the part of a predictor variable that is independent of all other predictor variables.
Comparing the equations, we get:
- This means holding
constant, a change of one in
is associated with a change of 0.5906 in the dependent variable.
- This means holding
b) We have to estimate the value of y
