The mean and the range of the set of numbers 1.20, 1.00, 0.90, 1.40,0.80, 1.20, and 1.10 are m and r respectively. Find m + r pls i'm submitting it tomorrow
My rechargeable fan stopped working because I over-greased the back end and grease went into the rotating mechanism. Is there a solution for this? Can Petrol be used to wash off grease from the rotor?

Sorry the 0.80 occurred twice
#Ngozi
mean(m) = (1.20+1.00+0.90+1.40+0.80+0.80+1.20+1.10)/8
=8.40/8=1.05
range(r) = 1.40 - 0.80 = 0.60
therefore;
m + r = 1.05 + 0.60 = 1.65
The answer is 1.65
thank you vey much!!!!!!!!!!
nice
