Answer:
as a fraction = 75/92
as a percentage = 81.52%
Step-by-step explanation:
total no of students = 92
probability that a student has hazel or brown eyes = Pr(hazel or brown)
but probability of a or b happening ie Pr(a or b) simply is Pr (a) +Pr (b)
therefore Pr(hazel or brown) = Pr(hazel)+ Pr(brown)
Pr(brown) = (no of brown eyes )/(total set of eyes)
= 
= 10/23
Pr( hazel) = (no of hazel eyes )/(total set of eyes)
= 
=35/92
hence Pr(hazel or brown) = (10/23) + (35/92) =75/92
so there's 75/92 probability (or 0.8 out of 1 chance )to choose either hazel or brown randomly

Solving for X
7vx−1=3
7vx=3+1
7vx=4
vx=4/7
x=4/7/v
x=4/7v
Solving for Y
7vx−1=3
7vx=3+1
7vx=4
vx=4/7
v=4/7/x
v=4/7x

Answer:
Step-by-step explanation:
Hello There!
The exterior angle of a triangle rule is that the exterior angle is equal to the sum of the interior opposite angles
So essentially what I'm saying is that
z = 29 + 39
29+39=68 therefore the measure of angle z is 68
