X-N(45, variance) and p(x>51)=0.288 find standard deviation
A C++ program to print the area of a rectangle by creating a class named Area having two functions, first function named as Setdim takes the length and width of rectangle as parameters and second function named as getArea returns the area of the rectangle, length and width are entered through keyboard.
Assuming that the samples come from normal distributions, find the margin of error E given the following.
2. n=150, x-=98, s=9.90, 95% confidence.
3. n=350, x-=125, s=11.18, 99% confidence.
4. n=500, x-=236, s=15.36, 90% confidence.
5. n=785, x-=459, s=21.42, 99% confidence.
If 20 candidates appear in a competitive exam. Then show that there exist at least 2 students among them whose roll number differ by a multiple of 19.
your friend gave you an encrypted text. He encrypted the text using the Alphabet Square cipher. It is a simple substitution cipher that make use of a square grid. The letters a-z written into the grid, with i and j typically sharing a slot (as there are 26 letters and Only 25 slots).This cipher generally takes a plain text as input and gives encrypted text as output.
To encipher a message ,each letter is merely replaced by its row and columns numbers in the grid.
Your given an encrypted string S as input print the decrypted text using the Alphabet Square.
NOTE:The input contains lowercase letters as the string.
