Write a real-world solution that can be represented by the equation y = 7x be sure to explain what the variables represented in the solution

(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

The parabola y = x² - 4 opens: a.) up b.) down c.) right d.) left
