Please help me to solve the following questions :
1. Find the equations of both the straight lines that are nclined at an angle of 45 degree with straight line 2x+y-3=0 and passing through point (-1,4)
2. S denotes the sum of first n terms of a geometric series 3 - 1 + 1/3 -... and I denotes the sum of infinity of this series.Find the smallest n such that |I-S|<0.0001
3. The number of accidents that occur on an assembly line has a Poisson distribution with a mean of 3 accidents a year . Find the probability that one randomly chosen year is free from accident and the probability that 2 years out of 5 years chosen at random are free from accidents .
4 .Continuous random variable X has the following probability density function:
f(x)={ 1/8 0<x<9;
0 otherwise
Continuous random variable Y is defined by Y=In X .show that P(Y<y)=1/8
Thanks .:!)
