The value of f(3) can be calculating by putting the variable x equal to 3 , x=3 which gives:
f(3)=81+3e-0.7*3=81+3e-2.1
But there is one more unknown in the equation e. e is a constant called Euler's number, after the Swiss mathematician Leonhard Euler.
e=2.7182818284590.....
Rounding to the nearest hundredth the thousandths place is used to determine whether the hundredths place rounds up or stays the same.
Rounding the Euler's constant to the nearest hundredths gives:
e=2.72
So, f(3)=81+3*2.72-2.1=81+8.16-2.1=87.06
Answer:number of children negative for chicken pox=28
Step-by-step explanation:
Number of children positive for chicken pox =18 out of 30
Therefore number of children negative for chicken pox is 12 out of 30 ie ( 30-18)
Such that the ratio of positive tested chicken pox children to negative tested chicken pox children =18:12
Therefore total ratio =18 +12=30
Suppose there are 70 children,then number of children negative for chicken pox =
12/30 x 70 =28
