64 copies.
1.) Divide 40 by 5 (you get 8)
2.) 8 is the number of copies that fits on a 1 foot shelf, so to find how many copies would fit on an 8 foot shelf, simply multiply 8(book copies) by 8( an 8 foot shelf).
3.) 8 times 8 is 64, so your answer is 64 books will fit perfectly on an 8 foot shelf. Hope this helped!

Answer:
The probability is 0.68
Step-by-step explanation:
We are going to use conditional probability to solve this problem.
We define the following events :
A : '' Alex replaced the starter''
B : ''Alex replaced the battery''
M : ''The engine works''
NM : ''The engine doesn't work''
Given two events A and B, we define the conditional probability:
Where P(A,B) = P(B,A) = P(A∩B) = P(B∩A)
In our problem :
Alex replaced the battery or either the starter ⇒
We need to find
We write :
P(M) = [P(M∩B) ∪ P(M∩A)]
P(M) = P(M∩B) + P(M∩A) - P[(M∩B)∩(M∩A)]
But P[(M∩B)∩(M∩A)] = 0 because he replaced the battery or either the starter
P(M) = P(M∩B) + P(M∩A)
P(M)=0.595+0.03
P(M)=0.625
P(NM)= 1-P(M)=1-0.625=0.375
P(NM)= 0.375
P(NM/B) = 1-P(M/B)=1-0.7=0.3
P(NM/B) = 0.3
The slope would be M= 16/15
