How long will it take for $6,500 to double at a simple interest rate of 7%? round to the nearest tenth of a year.

(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

Write the fraction 9/50 as a decimal if needed round to the nearest hundredth

Twelve less than a number is at most 20
