The probability of getting x even number :
(using the binomial probability)
30Cx (1/2)^x . (1/2)^(30-x)
Answer:
The given power series 
is a solution of the differential equation (1+x^2)y' + 2xy = 0
Step-by-step explanation:
This is a very trivial exercise, follow the steps below for the solution:
Step 1: Since n = 0, 1, 2, 3, 4, ........, Substitute the values of n into equation (1) below.
.....................(1)
Step 2: Find the derivative of y, i.e. y'
Step 3: Substitute y and y' into equation (2) below:
(Verified)
Since the LHS = RHS = 0, the given power series is a solution of the differential equation (1+x^2)y' + 2xy = 0

Answer:
Step-by-step explanation:
It is given that Todd is 30 year old and he perform aerobic activity that may increase his heart beat.
maximum heart beat can be calculated by subtracting the age from 220
For 30 year old male Maximum heart beat
=220-30=190
And during exercise his heart beat increases to 60-90 % of maximum value
60 % of 190=114 beats/min
90 % of 190=171 beats/min
So Heart beat can goes up to 114 - 171 beats/min
242 cm because 418/ 3.8 = 110, 110 x 2.2 = 242 cm
