Answer:
1.14 days (approximately)
Step-by-step explanation:
Family drives 350 miles per day
Let d = days
Equation: 350d = 400
d = 400/350
d is approximately 1.14 days
If you want to answer it without decimals, you should say around 2 days since it's going to take more than one day to travel.
Answer:
(a) 9 buildings
(b) 2^n -1
Step-by-step explanation:
The number of distinct non-empty subsets of b objects is 2^b -1. Since the subsets are distinct, each could represent a list of the buildings, from the set of b buildings, in which a student is taking courses.
(a) For 8 buildings, 2^8 -1 = 255 students could enroll. for 9 buildings, 2^9-1 = 511 students could enroll.
For 500 students, 9 buildings are required.
__
(b) The maximum number of students for n buildings is ...
2^n -1
