Answer:
53
Step-by-step explanation:
When I entered 53 into PLATO, it appears to be the correct answer.
In the absence of a specific question posed, below are the potential inquiries along with their respective answers:
P(fewer than 4 tosses)
= P(one toss) + P(two tosses) + P(three tosses)
= (3/4) + (3/4)(1/4) + (3/4)(1/4)^2
= 0.984375
Expected value
= 1 / p
= 1 / (3/4)
= 4 / 3
Variance
= (1 - p) / p^2
= (1 - (3/4)) / (3/4)^2
= (1/4) / (9/16)
= 4 / 9
Standard deviation
= sqrt(Variance)
= sqrt(4 / 9)
= 2 / 3
We start with

Next, we can factor out the term on the right side


Now, we will substitute back
resulting in
So,
.............Response
A(n)=a(1)+(n-1)d=
a(n)=2+(n-1)2=2+2n-2=2n
First note the ratio is
7:2 so divide 7 by 2 to get 7/2 = 3.5. Then add 3.5 to 2, yielding the result 5.5
