Answer
Relative risk= 0.742
Odds ratio= 0.745
Detailed calculation shown in diagram:
Well he started off right by solving for y=y to find the abscissa of the intersection points between the two points,but then he assumed that their ordinate (y coordinates) are both zero,which is incorrect obviously. To find their ordinate,all we have to do is plug the x values into any of the two equations, since they both will pass through that point ੴ
I chose to plug the values in the second linear equation, since it's easier to compute
<h2>

( 3 , 13 ) ( -2 , -7 )</h2>
Answer:
slope: 5
y-intercept: 3
therefore y=5x+3
Step-by-step explanation:
the slope is the value that is changing; as time passes the price increases by $5 per hour
the y-intercept is where the function crosses the y-axis (when x is 0); so when no time has passed.
Answer:
Step-by-step explanation:
Use a slope form.
<u>Slope:</u>
y₂ = (17)
y₁ = (1)
x₂ = (2)
x₁ = (-2)
Then, rewrite the problem.
Solve.
Therefore, the slope is 4, which is our answer.
I hope this helps you! Let me know if my answer is wrong or not.
I think you just divide the number of miles by the number of hours he spent driving.
2,482/42.5= 58.4
58mph
