Given a number N, write a program to print a triangular pattern of N lines with numbers as shown below.
Input
The input will be a single line containing a positive integer (N).
Output
The output should be N rows with numbers.
For example: If the given number is 4 --
1
121
12321
1234321
If given number is 7 --
1
121
12321
1234321
123454321
12345654321
1234567654321
Note: In left hand side there will be no gap ,it should look like Right Triangle.
Question 2.8 [2, 3, 3]
Suppose that a telemarketer has a 12% chance of making a sale on any given call. If the
telemarketer makes average of 5 calls per hour, calculate:
a) The probability that the telemarketer will make exactly 2 sales during the shift.
b) The probability that the telemarketer will makes more than 4 sales during the shift.
c) What is the probability that the telemarketer makes more than 2 call during two hours?
Question 2.6 [3, 3, 3]
Suppose that the height of seven-year old children is a normal random variable with mean 1.1m and
standard deviation 0.1m.
a) What proportion of seven-year old children are shorter than 0.95m?
b) What is the probability that a seven-year old child is taller than 1m but shorter than 1.175m?
c) Suppose that a family restaurant has a children’s play-place. The facilities in the play-place
can only be used by children below a certain height. What should the cut-off height be to
ensure that 99% of seven-year olds have access to the play-place?
Suppose the mean number of days to germination of a variety of seeds is 22, with a standard deviation of 2.3 days. Find the probability that the mean germination time of a sample of 160 seeds will be within 0.5 days of the population mean.
Box of mass 20 kilograms is kept on a smooth horizontal surface. Object of mass 16 kilograms is kept on the box. The two objects are connected by a light in extensible string and the string goes over smooth Pulley. A force of 6 Newton is applied on the box, the acceleration of the box?
