A) the equation accuretly models this scenario because Emanuel has a total of 48 cards. He bought some (X) and his aunt gave him 18. In order to find the number of cards he bought you set the number of cards he bought and the number of cards he got from his aunt equal to the number of cards he has.
B) 48= X + 18
Subtract 18 over
30=X
He bought 30 cards from the store.
48+ 30+18
<span>Answer:
We'll have to integrate the growth rate with respect to time, without forgetting the amount of area covered at the start.
A = 2010 + â« 8t1/2 dt (as t goes from 0 to 24)
A = 2010 + [(16/3) t3/2] (as t goes from 0 to 24)
A = 2010 + 627 = 2637 acres
We don't integrate the 2010 here because whatever effects of the passing of time have already taken place over that area. We just treat it as a constant and add it to the result of integration.</span>

Step-by-step explanation:
Let X be the random variable denoting the net gain(in dollars) for a single trial(one bet).
Assuming that each number in the wheel is equally likely, probability of the outcome being a victory is 
and probability of failure is 
. For a win, X takes value 35 and for a loss X takes value -1. So the model is,
The mean for one bet is
