Answer:
73.33% probability that they also took the SAT
Step-by-step explanation:
We have these following two events.
Event A: Taking the ACT exam. So P(A) = 0.3.
Event B: Taking the SAT exam. So P(B) = 0.37.
The conditional probability formula is:
In which P(B|A) is the probability of event B happening given that A has happened, is the probability of both events hapenning.
22% of graduating seniors too both exams.
This means that
If the student took the ACT, what is the probability that they also took the SAT?
73.33% probability that they also took the SAT
2^x = 32
x = 5

Answer:
Lots of people are just answering to get free points now, they're not actually giving answers.
(and sorry if you miss the way it used to be).
The other x-intercept is (2,0)
Given:
The geometric sequence is
To find:
The sum of first 8 terms of the given geometric sequence.
Solution:
We have,
Here, the first term is 4 and the common ratio is
The sum of first n terms of a geometric sequence is
Where, a is the first term and r is the common ratio.
Putting n=8, a=4 and r=-3, we get
Therefore, the sum of first 8 terms is -6560.
