15-(37+8)÷3=
how do you the work for this problem?

0

Step-by-step explanation:

P=( )

E=exponents

M/D=multiplication or division

A/S= addition or subtraction

15-(37+8)÷3

first you start out with whats inside the () which is (37+8) which equals (45)

15-(45)÷3

after you want to divide 45 by 3 which is 15

15-15

you get 0

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
