Answer:
Expected number of packs to be used after 15 days = 28.9 packs
The graph is shown below
Step-by-step explanation:
Number of packs of printer paper ordered = 135
Average number of days to use 135 packs = 70 days
Number of packs used per day = 135/70
Number of packs used per day = 1.9286 packs
Expected number of packs to be used after 15 days = 1.9286(15)
Expected number of packs to be used after 15 days = 28.9
The more the number of days, the more the number of packs used. This means that as the number of days increases, the number of packs used also increases.
