Answer:
Required probability is 0.784 .
Step-by-step explanation:
We are given that in a large statistics course, 74% of the students passed the first exam, 72% of the students pass the second exam, and 58% of the students passed both exams.
Let Probability that the students passed the first exam = P(F) = 0.74
Probability that the students passed the second exam = P(S) = 0.72
Probability that the students passed both exams = = 0.58
Now, if the student passed the first exam, probability that he passed the second exam is given by the conditional probability of P(S/F) ;
As we know that conditional probability, P(A/B) =
Similarly, P(S/F) = =
{As
is same as
}
= = 0.784
Therefore, probability that he passed the second exam is 0.784 .
Answer:
3
Step-by-step explanation:
It's given that ΔDEF ∼ΔXYZ . So the corresponding sides of both triangles will be proportional to each other.
DE = 4 ; XY = 4(n + 1) ; EF = 5 ; YZ = 7n - 1
Putting all these values gives ,

Step-by-step explanation:
we have
Find the inverse of A(x)
Let
y=A(x)
Exchange the variables x for y and y for x
Isolate the variable y
Let
------> function inverse of A(x)
<em>Explanation</em>
For x=1
Find the value of A(x)
The point (1,7) is a solution for A(x)
That means-----> The point (7,1) is a solution for the function inverse g(x)
Verify
For x=7
The point (7,1) is a solution for g(x)
therefore
A(x) and g(x) are inverses of each other if the point (x,y) is a solution of A(x) and the point (y,x) is a solution of g(x)
