Answer:
The best estimate of the number of times out of 39 that Ariana is on time to class is 27.
Step-by-step explanation:
For each class, there are only two possible outcomes. Either Ariana is on time, or she is not. The probability of Ariana being on time for a class is independent of other classes. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
The expected value of the binomial distribution is:
The probability that Ariana is on time for a given class is 69 percent.
This means that
If there are 39 classes during the semester, what is the best estimate of the number of times out of 39 that Ariana is on time to class
This is E(X) when n = 39. So
Rounding
The best estimate of the number of times out of 39 that Ariana is on time to class is 27.
Answer:
First page, first question the answer b, second question answer is a.
Step-by-step explanation:
When a function is positive, it moves towards the left, when it is negative it moves towards the right.
The number in the equation that represents the original amount of mice would be 14 since the 0.25x would be representing the rate the mice survive the treatment. As according to the exponential equation formula, y=ab^x, a is the value of the principal amount, b is the variable that represents the growth/decay rate, and the x value shows the amount of times the object/thing grows or decays.
Answer:
it is 1,436,998,653,436
Step-by-step explanation:
5(5)=25
110 000(0.25)=27 500
110 000+27 500=137 500
