Draw a tree diagram to find the number of possible outcomes.
How many 3-digit numbers can be formed from the digits 1, 2, 3, and 4 if no digit is repeated in any number? How mang of these numbers are odd? How many are greater than 300? How many arr divisible by 11?
Find the number of possible outcomes by systematic listing.
If two dice arr rolled, how many possible outcomes are there? How many of these have a dot sum greater than 8? Less than 10?
A triangular number is defined as m(m + 1)/2 for m = 1, 2, …, and so on. Therefore, the first few numbers are 1, 3, 6, 10, … . Write a function with the following header that returns a triangular number:
int getTriangularNumber (int n)
Write a test program that uses this function to display the first 75 triangular numbers with 5 numbers on each line.
1. Miss Romero noted that the mean scores of a random sample of 15 Grade 8 students who had taken a special test were 80.5. If the standard deviation of the scores was 3.1, and the sample came from an approximately normal population, find the point and the interval estimates of the population mean, using 95%confidence.
2. Edith has observed that the mean age of 18 youth volunteers in a barangay project is 17.5 years with a standard deviation of 2years. If the sample comes from an approximately normal distribution, what are the point and the interval estimates of the population mean? Adopt a 99% confidence level.
