Homework Answers
Due to presence of HOMEWORKLIB POLICY, I am answering 2 questions.
1.
Ans: m = 19, b = - 23
Explanation: Straight line equation is given as:
Equation: Y = - 23 + 19X
2.
Average snowfall = (32.8 + 56.4) / 2 = 44.6
If March data is above average, total average will rise.
If you are satisfied with the answer, please provide a positive rating. Feel free to comment in case of queries.
Have a nice day ahead!
