CATS
5
TREES
102
51 on each side of the avenue
I think we can all agree that while a fence would require 51. An avenue by definition would require trees on both sides.

The prof's body temperature is given by
from
dT/ΔT=-Cp*t and the initial condition (t=0) that ΔT=28ºT then
ΔT=28exp(-Cp*t)
Where ΔT is the temperature difference between the body and the room
Cp is the body heat loss constant
T is the time since death
@ 9:00AM ΔT=10ºF
@ 10:00AM ΔT=8ºF
so
10=28exp(-Cp*t) and 8=28exp(-Cp(t+1)) so Cp=ln(10/8)
going back to the body temp @ 9:00AM
t = ln(10/28)/ln(8/10)=4.614 hrs.
so the prof bought the chalk at about 4:30AM

:

and your studying til 12:00 midnight alibi needs some serious improvement.
Check
ΔT@9:00AM is about 28exp[-ln(10/8)*4.5]=10.25ºF
ΔT@ 10:00AM is about 28exp[-ln(10/8)*5.5]=8.20ºF
If it takes Mark 20 hours to paint a house and it takes Rap 30 hours, how long will it take if they work together yet independently
Country x is planning to attack country y, and country y is anticipating the attack. Country x can either attack by land or by sea. Country y can either prepare for a land defense or a sea defense. Both countries must choose either an all land or all sea strategy, they may not divide their forces. The following are the probabilities of a successful invasion according to both strategies used.
If x launches an attack by sea and y prepares a defense by sea the probability of a successful invasion is 80%.
If x launches an attack by sea and y prepares a defense by land the probability of a successful invasion is 100%.
If x launches an attack by land and y prepares a defense by land the probability of a successful invasion is 60%.
If x launches an attack by land and y prepares a defense by sea the probability of a successful invasion is 100%.
What should the strategy of country x be, assuming the goal is to maximize the probability of a successful invasion
Assume the goal of country y to be to minimize the probability of a successful invasion. What is the final probability of a successful invasion assuming both utilize an optimal strategy
