Answer:
12
Step-by-step explanation:
The big triangle all sides are the little triangle times 4. So 25 times 4 is 100, and 100 - 28 is 72, divide that by 6 to get 12.
-23.625 is the decimal number of -61 3/8
D. 53, 107
The pattern is multiplying the previous number by two and then adding one to it.
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
