Consider the following relation:
BIKE_SALE(Bike_ID, Salesperson_ID, Date_Sold , Sale_Commission,
Discount_Percentage)
Assume that a motorbike may be sold by multiple Salesperson, and hence
{Bike_ID, Salesperson_ID} is the primary key. Additional dependencies are:
 Bike_ID -> Date_Sold
 Bike_ID -> Discount_Percentage
 Date_Sold -> Discount_Percentage
 Salesperson_ID -> Sale_Commission
Identify if this relation is in 1NF, 2NF, 3NF? Please specify your reasons and
normalize if you think it is needed.

Suppose we have a byte addressable computer that has a 32-byte cache with 8 bytes per block. the memory address is 8 bits long. the system accesses memory addresses (in hex) in this exact order: 6e, b9, 17, e0, 4e, 4f, 50, 91, a8, ab, ad, 93, and 94. (a) assuming the cache is direct mapped, what memory addresses will be in cache block 2 after the last address has been accessed? (b) assuming the cache is direct mapped, what is the hit ratio for the entire memory reference sequence given, assuming the cache is initially empty? (c) assuming the cache is 2-way set associative with a lru replacement policy, what is the hit ratio?
