Answer:
solution is attached in the picture below
Step-by-step explanation:
the answer to it is 24X squared but the answer to your question is both are ok they both give u 12X which is 24X squared the way u wrote it lol
(5*180)/7=900/7=128.5714285714286
The angle is approximately 129 degrees.
<span />
Total number of students surveyed = 200
Number of male students = 80
Number of female students = 200 - 80 = 120
Number of brown eyed male students = 60
Probability of a brown eyed male student = 60 / 80 = 0.75.
Since, <span>eye color and gender are independent, this means that eye color is not affected by the gender. Thus, we expect a similar probability of brown eye for female as we had for male.
Let the number expected of brown eyed females be x, then x / 120 = 0.75.
Thus, x = 120(0.75) = 90.
Therefore, the number female students surveyed expected to be brown eyed is 90.</span>
