Answer:
Vel. of the car = 3.33 meter per second.
Explanation:
In given graph, y axis represent the distance traveled by the car and x axis represent the time taken by car.
At time t = 30 seconds , distance traveled by the car is 100 meter
We know that,
Speed = 
speed = 
speed = 3.33 meter per second
That's the final answer.
I hope it wil help you.
32 times 24 is $768 which us how much they spent
2.4 * 60 = 144 total minutes
It is 35 degrees a piece. Check the previous answer between both of us for clarification.
Hope I helped!
Good luck!
The assumptions of a regression model can be evaluated by plotting and analyzing the error terms.
Important assumptions in regression model analysis are
- There should be a linear and additive relationship between dependent (response) variable and independent (predictor) variable(s).
- There should be no correlation between the residual (error) terms. Absence of this phenomenon is known as auto correlation.
- The independent variables should not be correlated. Absence of this phenomenon is known as multi col-linearity.
- The error terms must have constant variance. This phenomenon is known as homoskedasticity. The presence of non-constant variance is referred to heteroskedasticity.
- The error terms must be normally distributed.
Hence we can conclude that the assumptions of a regression model can be evaluated by plotting and analyzing the error terms.
