1) each week jim buys 10 pounds of macadamia nuts to sell at his store, the nut hut. the number of pounds he actually sells in a week is a continuous random variable y, which has the following probability density function:

fy(y) = y/50 if 0 fy(y) = 0 otherwise

(a) graph this density function.
(b) find the probability that at most four pounds of macadamia nuts are sold.

If is congruent to,then m is the midpoint

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.
