A proportion is an equal ratio (or fraction)
18 divided by 18 is 1
72 divided by 18 is 4
so a proportion of 18:72 is 1:4
Answer:
x=4
Step-by-step explanation:
18=3(3x-6)
Divide each side by 3
18/3=3/3(3x-6)
6 = 3x-6
Add 6 to each side
6+6 = 3x-6+6
12 = 3x
Divide by 3
12/3 = 3x/3
4 =x
Since, the probability of success during a single event of a geometric experiment is 0.34.
We have to find the probability of success on the 6th event.
Since it is a geometric experiment. So, when a discrete random variable 'X' is said to have a geometric distribution then it has a probability density function (p.d.f.) of the form:
P=
, where q = 1 - p
So, now
P = 
where 'p' is the probability of success and 'q' is the probability of failure and x is the number of events.
Since the probability of success (p)is 0.34
Therefore, probability of failure(q)= 1 - p
= 1 - 0.34
= 0.66
and x = 6
So, P = 
= 
= 
= 0.0425
So, the nearest tenth of a percent of probability of success on the 6th event =
4.257 %
Rounding to the nearest tenth, we get
= 4.3%
So, Option A is the correct answer.
|2.5| because 2 and 1/2 are also 2.5 written in decimal, and the absolute value is always positive
