I'm going to rewrite f(t) to make it a little easier to use the power rule:

Now just take the derivative using the power rule:

Since they ask for f'(a), we need to replace the t's with a's:
Let x be a discrete binomial random variable that measures the number of successes in n trials.
Let p = 0.4 be the probability of success, that is, the probability that a deer has the aforementioned type of tick.
So the probability that 124 deer or less have this type of tick is calculated using the probability formula for a binomial distribution.
P (X <= x) = sum from x = 0 to x = 124 of (300! / ((X! * (300-x)!)) * (P ^ x) * (1-p) ^ n-x.
Finally the probability is 0.7030

Answer:
8n
Step-by-step explanation:
8n is the factor of both 8 and n. in the following question.
Factor ⇒ If a number, that use to divide another number and we get zero as a remainder, the number is called the factor of another number.
In this question, 8n is divided by both 8 and n and also we get zero as a remainder.
Therefore, 8n is the factor of both 8 and n .
Answer:
I think its B, but I could be wrong.
