Answer:
0.0326 = 3.26% probability that she is a student.
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is

In which
P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: Woman developer
Event B: Student
Probability that the developer is a woman:
7.4% of 25.8%(students).
76.4% of 100 - 25.8 = 74.2%(not students). So

Student and woman developer.
7.4% of 25.8%(students), so

If we encounter a woman developer, what is the probability that she is a student

0.0326 = 3.26% probability that she is a student.
Answer:
Step-by-step explanation:
complimentary angles, when added = 90 degrees
69 + 5n + 1 = 90
5n + 70 = 90
5n = 90 - 70
5n = 20
n = 20/5
n = 4 <====
Yes the left states your reasoning
Answer:
(f+g)x= 2x²+5x-3
The domain x∈ Real number.
Step-by-step explanation:
Given that f(x) = 5x - 3 and g(x) = 2x²
(f+g)x = f(x) + g(x)
So, by using the given function
(f+g)x= (5x-3) + (2x²)= 2x²+5x-3
As the result, 2x²+5x-3, is a polynomial, so domain of the result is all the real numbers.
