Pick 100 km for D...
<span>This would yield T=100 minutes </span>
<span>Using the question stem we calculate 80 km were traveled in 1h (or 60 minutes).... </span>
<span>This leaves us with 40 minutes (2/3 of an hour) to travel 20km..... </span>
<span>R*T=D </span>
<span>R*2/3=20 </span>
<span>R=30 </span>
<span>Answer A....</span>
set A = {2, 4, 6, 8, 10} (only even cards)
set B = {8, 9, 10} (8 or higher)
( A ∩ B ) means the numbers which are common in both sets .
They both have 8 & 10 in common.
So the answer is: P(A ∩ B) = {8,10}
The mean is basically the average.
To find the mean we need to add up all the values and divide it by the amount of games he played.
82 + 83 + 65 + 84 + 76 = 390
390/5
Mean = 78
