Hi,
The mean width of 12 ipads is 5.1 inches. The mean width of 8 kindles is 4.8 inches.
a) What is the total width of the ipads?.
b) What is the total width of the Kindles?.
c) What is the mean width of the 12 ipads and 8 kindles?.
for a) I multiplied 12 * 5.1 in =61.2. inches
b) I multiplied 8 * 4.8=38.4
now for the mean width of both devices I add the two results and divide them by 2
62.1+38.4 =100.5 ÷ 2 =50.25
Is this correct?
thanks,
eddy
