You have to find the area of each face and add them all together. You also need to find the unknown side which is indicated in the picture i attached.
(28 : 100) *6 = 1.68 (tax)
28 + 1.68 = 29.68 (total cost)
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
Jack should remove the maximum and minimum weight potatoes from the average weight of the potatoes to compensate for the extremes. Therefore, we are left with a data set of:
8, 9, 11, 7, 7, 8, 9, 7; so n = 8
The sum of these is 66
The average weight of each potato is:
66/8
= 8 ounces
