Find the difference (subtract) between the accepted value and the experimental value, then divide by the accepted value. To determine if a value is precise find the average of your data, then subtract each measurement from it.
when trying to find the slope of two given points use the formula m= y2 -y1/ x2-x1
so this is how you'd solve the equation:
y2= 2 y1= 0 x2= 3 x1= -3
the equation would be:
M=2-0/3+3
M= 2/6
M= 1/3
A = 9 (Sorry I can't do the other ones, I haven't learned those ones yet) Hope this helps!! :P
It depends if the dimention is solid. the deminsion has an areas of 60 and thats how many pounds the chemical weighs.
