Let x denote the reaction time, in seconds, to a certain stimulusand y denote the temperature (F) at which a certain reaction startsto take place. Suppose that two random variables x and y havethe joint density. f(x, y) = {4xy, 0< x < 1, 0 < y < 1 {0, elsewhereFind(a) P(0 <= x <= 1/2 and 1/4 <= y <= 1/2)(b) P(x < y)

This polygon has 4 sides
180(4-2) = 180(2) = 360 degree
80+90+2x + 3x = 360
170+5x = 360
5x = 190
x= 38
measure of angle t is 2(38)= 76
the answer is c. trust me
hope this !

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?
