Consider the planes 2x + 1y + 5z = 1 and 2x + 5z = 0.

(a) find the unique point p on the y-axis which is on both planes. ( ? , ? , ? )

(b) find a unit vector u with positive first coordinate that is parallel to both planes.
? i + ? j + ? k

(c) use the vectors found in parts (a) and (b) to find a vector equation for the line of intersection of the two planes, r(t) =
? i + ? j + ? k

Amajor grocery store chain is trying to cut down on waste. currently, they get peaches from two different distributors, whole fruits and green grocer. out of a two large shipments, the manager randomly selects items from both suppliers and counts the number of items that are not sell-able due to bruising, disease or other problems. she then makes a confidence interval. is there a significant difference in the quality of the peaches between the two distributors? 95% ci for pw-pg: (0.064, 0.156)
