Well I'm still trying to solve the first question so I'll tell you the other answers
the answer for the second question is :

and for the third question :
Answer:
Step-by-step explanation:
Domain is the x values. The interval of x-values that the function encompasses are from 0 inclusive to 7 exclusive. In interval notation that is [0, 7). The range is the y values. The interval of y-values that the function encompasses are from what looks like -2 to 4. In interval notation that is [-2, 4]. The domain goes from the lowest x-value to the highest; the range goes from the lowest y-value to the highest.
I just took the quiz, the answer is A: Critical values=0.312; there is sufficient evidence to support a claim of a linear correlation between before-and-after weights.
343=343=343
I am pretty sure this is the answer to the problem
To do this you have to divide 135 miles by 5 hours. You will get the answer of 27 miles per hour.
