The area as a function of b is given by
You want to find b such that a(b) = 36.
... (2/3)b^3 +6b = 36
... b^3 +9b -54 = 0 . . . . multiply by 3/2 to clear fractions
A graphing calculator shows this equation to have one real solution at b=3.
The value of b is 3.
Answer:
0.0021
Step-by-step explanation:
Given:
Probability of ordering a nonalcoholic beverage is,
Number of samples are
Now, the complement of event 'N' is not ordering a nonalcoholic beverage.
Therefore,
Now, for a sample of '10' customers, the probability of not ordering a non alcoholic beverage is product of their individual probabilities as all these events are independent events.
Therefore, probability that none of the 10 will order a nonalcoholic beverage is given as:
