Answer:
B(x)=(x_4)^2+5 that is the answer
Plug is the number try one and see if it equals and solve for y get y on one side
Answer:
P(x > 10) = 0.6981.
Step-by-step explanation:
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which
is the number of different combinations of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.
In this question:

P(x>10)

In which






So P(x > 10) = 0.6981.
