Answer:
Combinations refer to the combination of n things taken k at a time without repetition. To refer to combinations in which repetition is allowed, the terms k-selection, k-multiset, or k-combination with repetition are often used.
Step-by-step explanation:
in smaller cases it is possible to count the number of combinations. For example given three fruit, say an apple, orange and pear, there are three combinations of two that can be drawn from this set: an apple and a pear; an apple and an orange; or a pear and an orange.
Answer:
y = 0.75x + 1.95
Step-by-step explanation:
It is given that the variables:
y stands for total cost
x for the amount of songs.
It is also given that each song costs $0.75 to download, and that there is a standard flat-fee of $1.95 (per month).
Set the equation:
total cost for the month = cost per song * amount of song + flat fee subscription
or
y = 0.75x + 1.95
