Answer:
a) 0.8836
b) 0.7339
c) 0.2342
Step-by-step explanation:
Books classified as fiction = 94% or 0.94 probability
Books classified as non-fiction = 1 - 0.94 = 0.06
a) for two books, we get: 0.94 * 0.94 = 0.8836 Probability
b) The probability that all five books are fiction is: 0.94^5
This equals 0.7339 Probability
c) Probability that one books is non-fiction, while the other 4 are fiction is determined in the following way:
Probability of non-fiction * probability of fiction^(number of books)
0.06 * 0.94^4 = 0.0468
This does not account for the order at which the non-fiction book shows up. Such as the non-fiction book being the first book picked, or in another case - the non-fiction book being the last picked.
Since there are 5 ways this could occur, the total probability will be calculated as shown: 0.0468 * 5 = 0.2342 Probability
Hello,
tan (t)<0
==> sin (t) /cos (t)<0
==>1 / cos (t)<0 [since sin (t) ≠0, dividing by sin (t) ]
==> cos (t) <0

Answer:
pg. 1
teresa: use difference of 2 squares
rico: 6561 is not a perfect square
pg. 2
i think teresa is right and that 6561 can be broken down
problem 1: (x^4-81)^2=(x^2-9)^4=(x-3)^8
problem 2: a. false b. rico
pg. 3
problem 3: a. -1(3x+5)^2 b. teresa is right because it cant still be a perfect square trinomial while having a negative first term.
problem 4: a. (y+3)^2 b. teresa
pg. 4
problem 5: a. (x^n+y^n)(x^n-y^n) b. teresa
teresa got more right, rico is buying pizza
