Answer:
n= 26, so the answer would be 'B'.
Step-by-step explanation:
n-8=18
n=18+8
n=26
Basically you set it up 43/8+26/5. When you do that multiply 5 by 8 so the donominiter will be 40. Then multiply 5 by 43 which is 215 and 8 by 26 which is 208 so now you have the same donominiter... 215/40+208/40 add 215 to 208 that's 423/40 then you see how many times does 40 divide into 423 that's 10 and then you had 23 left so put 10 23/4 .if it was a case like 10 3/12 you could simplify it and that would be 10 1/4 ...
Answer:
20 %
Step-by-step explanation:
There is a total of 5 colors. The probability of landing on orange can be represented as 1(orange): 5(total). This answer can also be represented as 20%. To make 1:5 a percentage you divide 1 by 5, then multiply it by 100.

Answer:
The probability of the student will pass the quiz = .0546
Step-by-step explanation:
Given -
Total no of question = 10
If the student guesses on each question there are two outcomes true of false
the probability of guesses question correctly =
the probability of success is (p) =
the probability of guesses question incorrectly =
the probability of failure is (q) = 1- p =
If the student guesses on each question he must answered at least 8 question correctly
the probability of the student will pass the quiz =
= P(X = 8 ) + P(X = 9) + P(X = 10 )
=
=
=
=
= .0546
