.50 × N = 30
Divide both sides by .50
N = 60.
Isnt it 2.5 and ur welcome
By letting

we get derivatives


a) Substitute these into the differential equation. After a lot of simplification, the equation reduces to

Examine the lowest degree term
, which gives rise to the indicial equation,

with roots at r = 0 and r = 4/5.
b) The recurrence for the coefficients
is

so that with r = 4/5, the coefficients are governed by

c) Starting with
, we find


so that the first three terms of the solution are

Answer:
2*5*7
Step-by-step explanation:
2*5=10
10*7=70
False. Since the probability of one side of the coin is 3/10, the other must be 7/10.
