We are given
The current exchange rate is 2 guilders for every 3 florins
so,
2 guilders = 3 florins
now, we can find for 1 guilders
so, we get
now, we can multiply both sides by 17
now, we can simplify it
so, option-A........Answer
Complete question :
a. Of less than$720?
b. Of more than $840?
c. Between $680 and $760?
Answer:
0.500 ; 0.0013 ; 0.6827
Step-by-step explanation:
Given that :
Mean, μ = 720
Standard deviation, σ = 40
P(Z < x)
x = (x < 720)
Obtain the standardized value of x
P(x < 720) = (x - μ) / σ
P(x < 720) = (720 - 720) / 40
P(x < 720) = 0
P(Z < 0) = 0.5
B.) More than $840
P(x > 840)
P(x > 840) = (x - μ) / σ
P(x > 840) = (840 - 720) / 40
P(x > 840) = 120 / 40 = 3
P(Z > 3) = 0.0013499 (Z probability calculator)
c. Between $680 and $760?
P(760 < x < 680)
P(760 < x < 680) = ((x - μ) / σ) - ((x - μ) / σ)
P(760 < x < 680) = ((760 - 720) / 40) - (680 - 720) / 40)) = P( Z < - 1) - P(Z < - 1)
P(680 < x < 760) = 0.84134 - 0.15866 = 0.68268

Answer:
A. 0.083%
Step-by-step explanation:
Total population=60,000
Total infected=600
Percentage of total infected=600/60,000×100
=0.01×100
=1% of the total population
50 people died out of total infected
Percentage of death of total infected=50/600×100
=8.33%
Total death from all causes=110
Percentage of total death from all causes to the total population=110/60,000×100
=0.1833%
Proportionate mortality rate(PMR) of dengue in the population can be calculated as:
Percentage of death from total infected to the total population
=50/60,000×100
=0.0833%
Approximately 0.083%
