Step-by-step explanation:
The average scores s (on a 100 point scale) for the students can be modeled by
s = 75 - 6 In(t + 1), 0 < t < 12
where t is the time in months.
a) Since the students were given an exam and then retested monthly with equivalent exams, then,
For the original exam, t = 0
Therefore,
s = 75 - 6 In(0 + 1) = 75 - 6 In1
s = 75 - 6 × 0 = 75
b) the average score after 4 months, t = 4
Therefore,
s = 75 - 6 In(4 + 1) = 75 - 6 In5
s = 75 - 9.66 = 65.34
c) s = 60
Therefore,
60 = 75 - 6 In(t + 1)
6 In(t + 1) = 75 - 60 = 15
In(t + 1) = 15/6 = 2.5
t + 1 = e^2.5 = 12.18
t = 12.18 - 1 = 11.18
t = 11 approximately
The answer would be3.8356164375.This is because you have to divide 33,600 by 365 which gives you 92.0547945.The number 365 because of the amount days in a year.So that gave you the deaths per day.So then you divide it by 24.The number 24 because of 24 hours in a day.So, 92.0547945 by 24, this will give you the hourly rate of deaths.
H=price of house
s=price of lot
h+s=158,100
h=5s
(5s)+s=158,100
6s=158,100
s=26,350
h=5(26,350)
h=$131,750
100% is the max of percent and 100 penny's is a dollar so $.46 = 46% <span />
