First let us create an even split of the data into train and test partitions using createDataPartition. The code with a missing line is given below:
set. seed(2)
# line of code
test <- iris[test_index,]
train <- iris[-test_index,]
Which code should be used in place of # line of code above?
a. test_index <- createDataPartition(y, times=1,p=0.5)
b. test_index <- sample(2,length(y),replace=FALSE)
c. test_index <- createDataPartition(y, times=1,p=0.5,list=FALSE)
d. test_index <- rep(1,length(y))

Acomputer has a two-level cache. suppose that 60% of the memory references hit on the first level cache, 35% hit on the second level, and 5% miss. the access times are 5 nsec, 15 nsec, and 60 nsec, respectively, where the times for the level 2 cache and memory start counting at the moment it is known that they are needed (e.g., a level 2 cache access does not even start until the level 1 cache miss occurs). what is the average access time?
