Answer:
8/5 or 1.6
Step-by-step explanation:
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>
Answer:
x=30
Step-by-step explanation:
Angle sum in a triangle=180
x+3x+2x=180
6x=180
x=30
That’s confusing do you know the formula your supposed to use?
Y=4
-10/-10 = -40/-10
-40/-10 = 4
