Answer:
Mean = 28.38
Standard Deviation = 4.02
Step-by-step explanation:
Probability that a restaurant failed in the first year = p = 43% = 0.43
The probability of occurrence is constant. The events(failing of restaurants) are independent. Number of trials if fixed and there are only two possible outcomes i.e. either restaurant failed or not failed.
This scenario satisfies all the conditions of a Binomial experiment setting. So, we will use Binomial Experiment to answer the questions.
The formula to calculate the Mean of Binomial Distribution is:
Mean = u = np
Here, n is the number of trials, which is 66 in this case. So,
Mean = u = 66 x 0.43 = 28.38
Standard Deviation of a Binomial Distribution is calculated as:
Answer:
3 hours or 180 minutes
Step-by-step explanation:
1 hour for math
1 hour for science
1 hour for reading
Equals 3 hours or 180 minutes
32 seats per row.
If you divide 1,120 by 35 you get the answer. Its basically saying, how many groups of how many seats make up the total number of seats.
Answer:
i.e. 393650 kg.
Step-by-step explanation:
Given that Radium-226 is a radioactive substance with an annual decay rate of 0.04 %
Let the year 1937 be 0 year
Initially population was = 400,000 kg
Since decay rate is 0.04% per year after t years population would be
=
In 2017, t = 40 years (i.e. years lapsed form 1937)
Hence population
=
i.e. 393650 kg.
