In Newton’s rings experiment using light of two wavelengths , it is observed that 10 th order bright ring corresponding to wavelength 1 coincides with 15 th order dark ring corresponding to wavelength λ₂ when viewed by reflected light. Find the ratio of λ1 and λ₂
Assuming that the samples come from normal distribution, find the margin of error E given the following:
n = 16 and x̄ = 50 with s = 4.2, 95% confidence
the probability that applicants A, B and C are successful are 1/3, 2/3, 1/4 respectively. if the three were invited what is the probability that only two of them were successful

- Assume that the number of episodes per year of otitis media, a common disease of the middle ear in early childhood follows a Poisson distribution with 2.7 episodes per year. What is the probability of having at most 2 episodes in the first year of life? (Approximate your answer to 4 decimal places).
- Assume that the number of episodes per year of otitis media, a common disease of the middle ear in early childhood follows a Poisson distribution with 1.35 episodes per year. What is the probability of having 3 episodes in the first two years of life? (Approximate your answer to 4 decimal places).
Refer to the word 'Skyscraper', Explain the denotation and connotation of the word.
a) Create a java project named school
b) Add two classes, namely student and lecturer
c) In student class, create the following methods:
i. calculate_stud_age – This method should take year of birth of the student as a
parameter and calculate and return the student’s age
ii. calculate_ave_mark – This method should take three marks of the student ,
Math, English and Physics marks as parameters and return the average mark
d) In the lecturer class, create the following methods:
i. get_name – This method should take a string (name of the lecture) and
an integer (experience of the lecturer in years). This method should
output/display the name of the Lecture together with his/her designation
based on the years of experiences determined by the following:
Professor – if experience is >= 20 years
Associate professor – if experience is >=15 years
Senior lecturer – if experience is >= 10 years
Associate lecturer – if experience is >=5 years
Junior lecturer – if experience is <5 years
We’ve all had those annoying cell phone calls from Heather, Daisy, or Oscar, trying to sell life insurance or an additional car warranty. First Orion, a call protection agency, recently issued a report that suggested 45% of all cell phone calls in 2019 will be spam. Suppose 500 cell phone calls are selected at random. Use the normal approximation to calculate the probability that less than 100 of cell phone calls will be sparm.
