Answer:
75
Step-by-step explanation:
Complementary Angles always add up to 90 degrees
so the answer is 75
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 and Step-by-step explanation:
<u>For question A)
</u>
ABC is similar to PQR because of the AA similarity postulate. This postulate states that <u>if any two angles in a triangle are congruent to the other two angles in a triangle, then the triangles are similar.
</u>
<u>For question B)
</u>
The area would be k times more than the area of ABC.
The area of a triangle is bh/2, or base times height, divided by 2.
And since they both have 4, the one with the k will be k times greater.
Hopefully this helps!!

Answer:
3
Step-by-step explanation:
Since we know QR and RS are the same, we can add them together
6 + 6 = 12
Since the whole line is 15 we subtract 12 from 15
15 - 12 = 3
Answer:
108
Step-by-step explanation:
9 times 12 is 108
