Step-by-step explanation:
a) selecting 12 player from 20 players can be one in 
= 
= 
= 
b) since each position has an identity permutations can be used so
Number of ways = 
= 
= 
= 
c) coach permutes 4 players for position other than centers in 
ways and selects center in 3 ways
so, number of ways = 
=
=
The answer should be 41 in^2
Multiply the two probabilities together to get the answer. 3/10 ×8/10 = 24/100 or 24 %
Answer:

Step-by-step explanation:
Answer:
Mean qualifying speed
= 224.5669mi/hr
Speed that passed the average/mean
= 226.240mi/hr ,224.037mi/hr 226.484mi/hr, 225.172 mi/hr
Step-by-step explanation:
Let's understand what mean is then understand what mean qualifying speed is.
First mean is like the average of the seven speed listed below.
So let's find the mean.
Mean = (223.684+ 222.929+ 226.240
+224.037 +226.484+ 225.172
+223.422)/7
Mean = 1571.968/7
Mean = 224.5669
So the mean qualifying speed is those speed that qualifies when the mean is taken, i.e the speed that crossed the average.
Mean qualifying speed are
=226.240 ,224.037,226.484
, 225.172
