Answer: 125
Step-by-step explanation:
5 * 5 = 25
25 * 5 = 125
125 * 5 = 625
625 * 5 = 3,125
3,125 * 5 = 15,625
Each number is multiplied by 5
Using the binomial distribution, it is found that there is a 0.056 = 5.6% probability that more than 7 will make a purchase.
<h3>What is the binomial distribution formula?</h3>
The formula is:
The parameters are:
- x is the number of successes.
- n is the number of trials.
- p is the probability of a success on a single trial.
In this problem:
- There are 12 customers, hence n = 12.
- The probability of any of them making a purchase is of p = 0.4.
The probability that more than 7 will make a purchase is given by:
P(X > 7) = P(X = 8) + P(X = 9) + P(X = 10) + P(X = 11) + P(X = 12).
Hence:
Then:
P(X > 7) = P(X = 8) + P(X = 9) + P(X = 10) + P(X = 11) + P(X = 12) = 0.042 + 0.012 + 0.02 + 0 + 0 = 0.056.
0.056 = 5.6% probability that more than 7 will make a purchase.

The choices are:
<span>A. The graph will rise to the right and to the left </span>
<span>B. The graph will rise to the right and fall to the left </span>
<span>C. The graph will fall to the left </span>
<span>D. The graph will fall to the left and to the right
If the degree of the polynomial is 4, then it is expected that there are three inflection points where the graph can go left or right. These points can be considered as maxima or minima. In this problem, the most sensible answer would have to be A.</span>
