find the area of the surface generated when the given arc is revolved about the y axis ( y= 4 - x^2 from x=0 to x=2 )
Write a program that works with fractions. Your program should be able to add,
subtract, multiply, and divide two fractions. Write a separate function for addition,
subtraction, multiplication and division. Specifically, your program must request
two fractions from the user, getting the numerator and denominator separately for
each fraction, and the operation to perform (add, subtract, multiply, or divide).
Your program will then compute the resulting fraction, keeping the numerator and
denominator separate, and output the result.
Note:
Make the structure for fractions. Then declare variable of fractions and use
them for addition and multiplication etc....
C. Let p and q be proposition
p: 4 is a rational number
q: √3 is an irrational number
Express each of these proposition as an English sentences:
- ~p
- p∨ q
- p ∧ q
- p → q
- p ↔ q
Random samples of size 𝑛 = 2 are drawn from a finite population
consisting of the numbers 5,6,7,8, and 9.
a. Find the mean of the population 𝜇.
b. Find the standard deviation of the population 𝜎.
c. Find the mean of the sampling distribution of the sample means 𝜇𝑋̅.
d. Find the standard deviation of the sampling distribution of the sample
means 𝜎𝑋̅.
e. Verify the Central Limit theorem by:
I. Comparing 𝜇 and 𝜇𝑋̅.
II. Comparing 𝜎 and 𝜎𝑋̅.
6. Write a Java program that will print the following series until it reaches 100.
1 1 2 3 5 8 13 …………………………
7. Write a java program to find the sum of the series up to the nth term where n is input by the user.
1+(1+n)+(1+n+n)+(1+n+n+n)……………….nth Term
Example: input n = 6
Output: 1+7+13+19+25+31 = 96
4. Write a program (without using an array) that accepts three numbers from the user and prints "increasing" if the numbers are in increasing order, "decreasing" if the numbers are in decreasing order, and "Neither increasing or decreasing order" otherwise.
Example: Input first number: 1524
Input second number: 2345
Input third number: 3321
Expected Output :
Increasing order
