The mean is the "average" you're used to, where you add up all the numbers and then divide by the number of numbers. The "median<span>" is the "middle" value in the list of numbers. ... If no number in the list is repeated, then there is no </span>mode<span> for the list.</span>
The ratio In simplified form of those who both bike and run to those who do neither is 12: 1.

<h3>What is Ratio ?</h3>
When two numbers are divided and written in the form p:q then they are called in Ratio.
It can be understood from the data given
The people who run and Bike is 42
The people who do neither is 3
The ratio of those who both bike and run to those who do neither is 42 :3
In simplified form 12: 1
Therefore the ratio In simplified form of those who both bike and run to those who do neither is 12: 1.

Answer:
The answer to your question is:
a) P(3) = 5818 mosquitoes
b) 4 days
Step-by-step explanation:
Data
P(t) = Poekt
a)
Po = 1000 mosquitoes
Pt = 1800
t = 1 day
P(3) = ?
1800 = 1000 e1k
1800 / 1000 = e 1k
e 1k = 1.8
1k = In 1.8
k = 0.587
P(3) = 1000 e (0.587)(3)
P (3) = 1000 e 1.761
P(3) = 5818. 2 mosquitoes
b)
P(t) = 10,000
10000 = 1000 e 0.587t
10000 / 1000 = e 0.587t
10 = e 0.587t
In 10 = in e 0.587t
2.3 = 0.587t
t = 3.92 days ≈ 4 days
