A university graduate standing on the ground fires a rocket into the atmosphere at a velocity of 4000 m/s at an angle of 20 degrees to the vertical axis. Determine (g = 9.8 m/s2):
(a) The time of flight

student is to match three historical events (Mahatma Gandhi’s Birthday, India’s freedom,
and First World War) with three years (1947, 1914, 1896). If he guesses with no knowledge
of the correct answers, what is the probability of the number of answers he gets correctly?
Suppose the population consists of the scores of 6 students in a certain examination, as follows: 9, 11, 13, 15, 17 and 19. By using the sampling distribution, estimate the population mean using a random variable of the size n=2.

Activity IV CHECK WHAT YOU KNOW. Solve the following problems. (2 points each)
1. Given n = 12; = 120 ml;s = 6. The parent population is normally distributed.
Find:
a. The point estimate.
b. The interval estimate of mean.
2. Rochelle wants to know the mean of all entering trainees in a boot camp. The mean age of a
random sample of 25 trainees is 18 years and the standard deviation is 1.3 years. The sample
comes from normally distributed population. Use a = 0.1 to find the following:
a. The point estimate.
b. The error.
c. The interval estimate of the population of the mean.
1. Write C++ program, overload the unary decrement operator (--) , postix nd prefix
2. Write C++ program , overload the binary subtraction operator(-)
Les assume you create a system which asks the user for the number of students and the
number of test scores per student. A nested inner loop, should ask for all the test scores for one
student, iterating once for each test score. The outer loop should iterate once for each student
and take student name as input. After taking input for 3 test scores, calculate average for each
student. Take 3 test scores and 4 students.
Note: use do-while loops
Man's Best Friend
by CodeChum Admin
We all know what man's best friend is. A dog! 🐶
Let's create one in our program using the pre-existing struct Dog provided.
Instructions:
- In the code editor, you are provided with the definition of a struct Dog. This struct needs a string value for its breed. Furthermore, you are provided with a displayDog() function which accepts a struct Dog as its parameter.
- Your task is to create a Dog, take in a string user input, and then set it as the Dog's breed.
- Finally, call the displayDog() function and pass that Dog you created.
