Answer:
Step-by-step explanation:
Team A : the mean height (average) is :
(75 + 64 + 78 + 65 + 68) / 5 = 350/5 = 70 inches
the range is highest number minus lowest number ...78 - 64 = 14
Team B : the mean height (average) is :
(76 + 68 + 70 + 74 + 67) / 5 = 355/5 = 71 inches
the range is : 76 - 67 = 9
===========================================================
A). nope....it mentions nothing of the weight

You need only set up a proportion.
11 cm/16.5 cm = 4 cm / x Cross multiply
11x = 16.5 * 4
11x = 66 ' Divide by 11
x = 66/11
x = 6
The expanded height is 6 cm Answer
