Find the joint probability density function of the two random variables x and y whose joint dist. function is given by: f (x, y) = use this joint probability density to find p(x + y > 3).

5,600 x 10^3 = a) 560 b) 5,000,600 c) 5,600,000 d) 56,000

Arefrigeration system at your company uses temperature sensors fixed to read celsius (°c) values, but the system operators in your control room understand only the fahrenheit scale. you have been asked to make a fahrenheit (°f) label for the high temperature alarm, which is set to ring whenever the system temperature rises above –10°c. what fahrenheit value should you write on the label

To solve the system of equations below, grace isolated the variable y in the first equation and then substituted into the second equation. what was the resulting equation? 3y=12x x^2/4+y^2/9=1
