Find the distance between the following points. a (-3, -2) and b (-8, 5) .

(a) (8%) compute the probability of an even integer among the 100 integers 1! , 2! , 3! , until 100! (here n! is n factorial or n*(n-1)*(n-2) *… 1) (b) (16%) compute the probability of an even integer among the 100 integers: 1, 1+2, 1+2+3, 1+2+3+4, …., 1+2+3+… + 99, and 1+2+3+… + 100

One integer is 8 times another. if the product is 72, then find the integers

Which shows one way to determine the factors of 4x3 + x2 – 8x – 2 by grouping?
