help me pleasee

Consider a memory system that is composed of one cache and a main memory. The access to the main memory takes 11 ns. Given a clock frequency of 8 GHz. an instruction miss rate of 16%, and data instruction miss rate related to load and store instruction is 20%. Assume that the base CPI of 1 and that the percentage of instructions related to store and Load is 28%. Calculate the delay caused by the cache in terms of i(the number of instructions). Answers are displayed to the nearest 2 decimal. Select one: O a. 19.011 b. 31.681 c. none of the options d. 38.721 Consider a memory system that is composed of one cache and a main memory. The access to the main memory takes 23 ns. Given a clock frequency of 9 GHz an instruction miss rate of 14%, and data instruction miss rate related to load and score instruction is 5%. Assume that the base CPI of 1 and that the percentage of instructions related to store and Load is 25%. Calculate the CPI for the system taking into consideration the delay caused by the memory system. Answers are displayed to the nearest 2 decimal.
