Answer: Irrational, assuming b is irrational
Step-by-step explanation:
You didnt state what "b" is, but:
Youre dividing "a" by an irrational number. you could do something simple like 4 divided by pi. Youre going to get an irrational number

Answer :
0.53
Step-by-step explanation:
Given the following :
Probability of female = probability of success on a single trial = 0.51
Number of babies = 80
Probability that more than half of the babies are female : p(X >80/2) = P(X > 40)
The problem can be solved using the binomial probability function :
P(X > 40) = [ p(X= 41) + p(X= 42) +.... +p(X= 80)]
In other to save computation time, we can use the binomial probability calculator
Hence ; P(X > 40) = 0.527 = 0.53
-5x-10=2(x-4)
-5x-10=(2•x)(2•(-4)
-5x-10=2x-8
-5x-10+10=2x-8+10
-5x=2x+2
-5x-2x=2x-2x+2
-3x=2
-3x\-3=2\-3
x=0.666
x=0.67
A) cranberry : apple
3 : 5
6 : 10
12 : 20
30 : 50
33 : 55
b) These quantities are proportional because they are the same as 3/5 just doubled, tripled etc. For example, 3/5 is proportional to 6/10 because both the numbers were multiplied by the same number. In this case it's 2.
