Answer:
1 / 12
Step-by-step explanation:
Given the following data:
_______A___ B ___C ___Total
Male__ 10 __ 17 ___6___ 33
Female_ 11__ 15___ 13___ 39
Total___21__ 32__ 19___ 72
Find the probability that the student was male AND got a "C"
Number of males who got C = 6
Total number of student students = 72
P(student was male and got C) = (number of males who got C / total number of students)
= 6 / 72
= 1 / 12

Answer:
area = 250 in²
Step-by-step explanation:
5 x 2.5 = 12.5 in
8 x 2.5 = 20 in
area = 20 x 12.5 = 250 in²
We can plug those values into the equation, and if the answer is incorrect, we'll know if either one is extraneous.
√11 - 2(-7) = √(-7)^2 + 4(-7) + 4
√25 = √25
5 = 5
The first solution, -7, makes the equation true, and so it is not extraneous.
√11 - 2(1) = √(1)^2 + 4(1) + 4
√9 = √9
3 = 3
The second solution, 1, makes the equation true, and so it is also not extraneous.
<h3>The correct option is D, neither solution is extraneous. </h3>
Recall the secant-tangent theorem, and you have
EA^2 = EC*CD
12^2 = 8*(x+10)
and now ED = EC+CD = 8+x+10
