Jose tracks how many times he got fast food each month. He got fast food 12 times in January, 10 times in February, 18 times in March, 4 times in April, and 2 times in May. Find the median number of times getting fast food.

In which form is the following function written? y = - 2(x – 3)(x + 5)

A. 15 degrees b. 45 degrees c. 30 degrees d. 60 degrees

The discrete random variables x and y take integer values with joint probability distribution given by f (x,y) = a(y−x+1) 0 ≤ x ≤ y ≤ 2 or =0 otherwise, where a is a constant. 1 tabulate the distribution and show that a = 0.1.2 find the marginal distributions of x and y. 3 calculate cov(x,y).4 state, giving a reason, whether x and y are independent. 5 calculate e(y|x = 1).
