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

Answer: b. y=5
Step-by-step explanation:
Take the cube root of both sides.
![y=\sqrt[3]{125}](https://tex.z-dn.net/?f=y%3D%5Csqrt%5B3%5D%7B125%7D)
Calculate.
y=5
Answer:
1. Area = Base * Height
2. 144x = 4x * 4x
3. 144x = 16(x^2)
4. 9x = x^2
5. x = 9
Step-by-step explanation:
In order to solve this kind of problem, we must find the difference between two negative numbers describing elevation. Although when you have 2 negative numbers in a subtraction-elevation problem, the elevation difference won't be negative... It would be positive. -56 - (-14) would usually equal -42 feet but that would just describe a regular negative subtraction problem, so it becomes 42 feet. This answer is positive since it describe the distance between these integers.
