Answer:
The expected value is an expression of the weighted average and can be taken as the (arithmetic) mean
As the number of trials is increased in a binomial experiment, the expected values obtained, in each of the set of trials continuously tend to the theoretical expected value
Step-by-step explanation:

Answer:
(X+2) and (X-5)
Step-by-step explanation: (X+3)*x-3(X+3)-10
=(X*2+6X+9)-(3X+9)-10
=X*2+6X+9-3X-9-10
=X*2+3X-10
X=(-b+/-(b*2-4ac)*1/2)/2a
a=1, b=3, c=-10
=-3+/-((3)*x-4(1)9-10))*1/2/2(1)
=-3+/-(9+40)/2
=(-3+/-7)2
Therefore 1. (-3-7)/2, and 2. ((-3+7))/2
1. -10/2=-5, X=-5 therefore (X+5)
2. (4/2)=2, X=2 therefore (X-2)
60 minutes = 1 hour<span>12 inches x 60 minutes = 720 inches per hour
</span><span>12 inches = 1 ft</span><span>720 inches per hour / 12 = 60 ft per hour</span> Tortoise B is faster.
