A. There is a positive correlation between the temperature and the amount of ice cream sold. This means that as the temperature increases the amount of ice cream also increases.
B. For the best fit you must calculate the slope between two points that are more-or-less representative of the entire graph. In this case it seems to have already done this with certain points so if you take the points (15,35) and (0,5) you can calculate the slope between these two points which is m=(35-5)/(15-0)=30/15=2. So the best fit slope for this particular case would be two and you would just draw a line through the graph at approximately the middle of the dots to best represent all of the data.
and the y-intercept is 5 so the approximate equation for the graph would be y=2x+5
Step-by-step explanation:
You have to have tracing paper or patty paper (cause that's what my teacher uses). Next you draw the figure along with the x and y-axis on it as well. Then you mark the x and y-axis and rotate the paper 90 degrees clockwise. Lastly if the x-axis is on the y-axis, mark it as the y-axis and if the y-axis is on the x-axis, also mark it as the x-axis.
I hope this helped :)
24. 9×4=36 4×-3=12 so 36+(-12)=24
Consecutive numbers differ by one, which means that if you start with a certain integer
, you obtain the next integer by adding one.
So, if you start with
, the three consecutive numbers are

The sum of these three numbers is

This number is divisible by 3 because you can write it as

Note that this is true in general: the sum of three consecutive numbers is always divisible by three, because it is three times the middle number.
