Round the following value
to the nearest minute.

Answer 1

Answer:

• 43 minutes
• $47

Step-by-step explanation:

1. Cell phone usage

Mon to Sun = 38, 62, 40, 10, 30, 55, 65

• Mean = (38+62+40+10+30+ 55 + 65)/7 = 43 minutes rounded

2. Water bills

Jan to Dec = $40 $42 $40 $38 $48 $50 $58 $62  $56 $46  $44 $44

• Mean = (40+42+40+38+48+50+58+62+56+46+44+44)/12 = $47 rounded
