Answer:
y = 22⅘
Step-by-step explanation:
5x = 4
x = 0.8
y + 62(0.8) - 3y = 4
2y = 49.6 - 4
2y = 45.6
y = 22.8

P = 4r + 3t
4r = p - 3t
r = (p - 3t)/4
You're looking for the extreme values of
subject to
. The Lagrangian is

with critical wherever the partial derivatives vanish:




Substituting the first three solutions into the last equation gives



At these points, we have


so the highest temperature the bee can experience is 28º F at the point (1, 2, -2), and the lowest is -26º F at the point (-1, -2, 2).
Answer: 2/5
Step-by-step explanation:
Number of cans of red paint = 3
Number of cans of blue paint = 5
Number of cans of green paint = 8
Number of cans of yellow paint = 4
Total number of cans of paint = 20
The probability that Eduardo will
choose a can of red paint or a can of blue will be:
= P(red) + P(blue)
= 3/20 + 5/20
= 8/20
= 2/5
The probability is 2/5.
