Answer: The variables have a weak positive correlation
Since r > 0, the correlation is positive. It's a weak correlation because r is closer to 0 than it is to 1.
Answer:
t = 350
Step-by-step explanation:
subtract 250 from each side, and then you'll have t = 350
Answer:
The graph in the attached figure
Step-by-step explanation:
we have

This is the equation of the line
To graph a line we need two points
<em>Find the intercepts</em>
1) The y-intercept is the value of y when the value of x is equal to zero
For x=0


The y-intercept is the point (0,3)
2) The x-intercept is the value of x when the value of y is equal to zero
For y=0


The x-intercept is the point (-1.5,0)
To draw the graph of the line plot the intercepts and join the points
using a graphing tool
see the attached figure
