Answer:
A. only II
Step-by-step explanation:
Mathematics calculus differentiates things into discrete and continuous. Discrete things have indivisible units, the example will be how many dogs in a village. There is no half dog, it's either one, two, etc. But the distance covered by train can be written as half miles, it's divisible unit.
The number of books and bracelets also discrete, thus the answer is A.

Answer: The value of cross price elasticity is 1.6.
Step-by-step explanation:
Since we have given that
Percent change in price = 10%
Percent change in quantity = 16%
So, we need to find the cross price elasticity between the two movie club memberships.
As we know the formula for cross price elasticity :

Hence, the value of cross price elasticity is 1.6.
Answer:
1.4 times as long
Step-by-step explanation:
3 1/2 (convert to mixed number) --> 7/2
2 1/2 (convert to mixed number) --> 5/2
(7/2) / (5/2) --> 7/5 --> 1.4
