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: the cost of the love seat would be $89
Step-by-step explanation:
Let cost of sofa be x
let cost of love seat be y
x + y = 267
x = 2y
2y + y = 267
3y = 267
3/3y = 267/3
y = 89
hope it helps :)
Answer:
The distance between w=1+2i and z=3-i is 3.61
Step-by-step explanation:
We need to find the distance between w=1+2i and z=3-i
The formula used is: 
We have 
We will use only real numbers and not i for calculating distance.
Putting values and finding distance

So, The distance between w=1+2i and z=3-i is 3.61
