Step-by-step explanation:
we know that the circumference is equal to
we have
substitute
The answer is d (i.e. 51).
the first 9 pages utilize 9 digits. the remaining 21 pages utilize two digits number. Therefore,
21*2=42
the total is 42+9=51
To get the probability of selecting a person who is a
democrat and is favour to the issue, let us first calculate for the portions in
each party who is favour on the issue.
p (rep & favour) = 0.4 * 0.3 = 0.12
p (dem & favour) = 0.6 * 0.7 = 0.42
Therefore the total portions who are favour is:
p (favour) = 0.12 + 0.42 = 0.54
Hence the probability is:
P (dem & favour) = 0.42 / 0.54 = 0.7778 = 0.78
Therefore there is about 78% probability that the person
selected who is favour to the issue is a democrat.
The answers are 6, 7, 8, and 11.
Hope this helps! :D
