Each front tire on a particular type of vehicle is supposed to be lled to a pressure of 26psi. Suppose the actual air pressure in each tire is a random variable X for the right tire and Y for the left tire, with joint pdf f(x, y) = K(x^2 + y^2) 20 ≤ x ≤ 30, 20 ≤ y ≤ 30
Calculate the correlation coefficient and discuss

Jan and wayne went to the store to buy some groceries. jan bought 2 cans of corn beef hash and 3 cans of creamed chipped beef for $4.95. wayne bought 3 cans of corn beef hash and 2 cans of creamed chipped beef for $5.45. which assignment of variables can be used in finding the cost of each item in the word problem on the left? j = the number of cans jan bought w = the number of cans wayne bought h = the unit price of corn beef hash c = the unit price of creamed chipped beef j = the total cost of jan’s bill w = the total cost of wayne’s bill
