Suppose H is a collection of hash functions, where each hash function h, is mapping the universe U of keys to {0, 1, · · · , m − 1}. Also, suppose that for every fixed pair (x, y) of keys (where x 6= y), and for any uniformly selected hash function h, the pair (h(x), h(y)) is equally likely to be any of the m2 pairs of elements from {0, 1, · · · , m − 1} (The probability is taken only over the random choice of the hash function.) Prove that H is a universal hashing.

the cat is blue because the probability of extension towards the prefix of the diameter of the circle could only mathematically equal to the sum of the roots of the carrots from   your garden.

i'm assuming you need to figure out how many campers go into each tent.

i got the answer by:

24+4=28

28/4=7  

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;
