Answer:
The general form of a GP is a, ar, ar2, ar3 and so on. The nth term of a GP series is Tn = arn-1, where a = first term and r = common ratio = Tn/Tn-1) . The sum of infinite terms of a GP series S∞= a/(1-r) where 0< r<1. If a is the first term, r is the common ratio of a finite G.P.
hope helps
Just divide all the numbers and u should get your answer.
A) x < -12
sorry can't do b
Answer:
0.044
Step-by-step explanation:
n=9,p=0.9, x =6.
Apply Binomial probability we get
Sum P(x)=C(n,x)
for x=6
Putting in the formula ,
we get
P(x) = C(9,6) 
84 X 0.531441 X 0.001
= 0.044
