Answer:
The Ballwin Bears are taller on average, and the Aviston Aces have players whose heights are more consistent.
Step-by-step explanation:
for derby dragon;
mean height = 72 inches
standard deviation = 1.2 inches
for aviston aces:
mean height = 70.8
standard deviation = 0.7 inches
for balwin bears;
mean height = 73 inches
standard deviation = 1.0 inches
the mean height of aviston aces < mean height of derby < mean height of balwin bears
So on average the balwin bears are taller.
The standard deviation of derby dragon is > that of balwin bears > aviston aces.
So the more consistent height is that of aviston aces players.
Answer: Choice D)
===========================================================
Work Shown:
Point A starts at (-2,3) and moves to (2,5) after applying the translation rule of "shift 4 to the right, 2 up".
Use the distance formula to find the distance from (-2,3) to (2,5)
I think this would be ur answer 2000.05
Answer:You can put this solution on YOUR website!
The numbers are between +/- 2 sd s of the mean
With Chebyshev's inequality, at least 3/4 of the numbers would be between these two.
For the one with 3 standard deviations, it would be 8/9.
----------------------
For the second part, this is 3.5 sd s on either side
1/(3.5)^2=0.0816, The fraction is 1/(49/4) or 4/49.
----------------
The second one would be wishing 18/8 or 2.25 sd s and that fraction would be 1/(9/4)^2=1/81/16 or 16/81 or 0.1975.
