Linear, because the r value for the linear model is closest to 1
Step-by-step explanation:
Given is a table showing the relationship between time spent running and distance traveled
The table is plotted on the rectangular coordinate graph with time in x axis and distance in y axis.
The graph is enclosed below
The line exactly contains all the points and also we find that correlation coefficient for the data =1
This implies that there is a linear relationship between the two variables.
Positive strong linear relationship exists.
Linear, because the r value for the linear model is closest to 1
is the right answer.
95
Step-by-step explanation:
Required Average
=
80
Let the required grade be
x
.
Average
=
Sum of
