Answer:
a) 3/100
Step-by-step explanation:
There are 25 total chips
P(Yellow) = 3/25
With no replacement P(Blue) = 6/24 = 1/4
Multiply 3/25* 1/4= 3/100
Answer:
52
Step-by-step explanation:
for every 4 pencils there is 1 eraser. 4/1=208/x
4x=208
x=52
Answer:
20,158 cases
Step-by-step explanation:
Let
represent year 2010.
We have been given that since 2010, when 102390 Cases were reported, each year the number of new flu cases decrease to 85% of the prior year.
Since the flu cases decrease to 85% of the prior year, so the flu cases for every next year will be 85% of last year and decay rate is 15%.
We can represent this information in an exponential decay function as:
![F(t)=102,390(1-0.15)^t](https://tex.z-dn.net/?f=F%28t%29%3D102%2C390%281-0.15%29%5Et)
![F(t)=102,390(0.85)^t](https://tex.z-dn.net/?f=F%28t%29%3D102%2C390%280.85%29%5Et)
To find number of cases in 2020, we will substitute
in our decay function as:
![F(10)=102,390(0.85)^{10}](https://tex.z-dn.net/?f=F%2810%29%3D102%2C390%280.85%29%5E%7B10%7D)
![F(10)=102,390(0.1968744043407227)](https://tex.z-dn.net/?f=F%2810%29%3D102%2C390%280.1968744043407227%29)
![F(10)=20,157.970260446597\approx 20,158](https://tex.z-dn.net/?f=F%2810%29%3D20%2C157.970260446597%5Capprox%2020%2C158)
Therefore, 20,158 cases will be reported in 2020.
4 and 8/10 but simplified it's 4 and 2/5
