There are 7 keys in each octave (C,D,E,F,G,A and B) so it would make sense to divide 52 to 7.
52/7=7 octaves and 3 extra kets
Answer:
10t - 16
Step-by-step explanation:
4(t + 2)+ 6(t - 4)
4t + 8 + 6t -24
10t - 16
Answer:
B. 0.4
Step-by-step explanation:
Use the definition of the probability
![Pr=\dfrac{\text{Number of all favorable outcomes}}{\text{Number of all possible outcomes}}](https://tex.z-dn.net/?f=Pr%3D%5Cdfrac%7B%5Ctext%7BNumber%20of%20all%20favorable%20outcomes%7D%7D%7B%5Ctext%7BNumber%20of%20all%20possible%20outcomes%7D%7D)
You have to find the probability that a randomly selected reference book is hard cover. Hence, from the table
- Number of all possible outcomes = Number of Reference books = 25
- Number of all favorable outcomes = Number of Hardcover Reference books = 10
So, the probability is
![Pr=\dfrac{10}{25}=\dfrac{40}{100}=0.4](https://tex.z-dn.net/?f=Pr%3D%5Cdfrac%7B10%7D%7B25%7D%3D%5Cdfrac%7B40%7D%7B100%7D%3D0.4)
