The function represents the number of accidents (f(x)) per 50 million miles driven as a function of the driver's age (x).
f(45) indicates that you have to find the value of f(x) when x=45, to do so replace the equation of the function with the value of x and solve for f(x)
For x=45 years f(x)=190
f(45)=190; This value indicates that 45-year-old drivers had 190 accidents per 50 million miles driven.
Answer:
B) Yes, because the proportion of the sample whose favorite pizza is pepperoni is about 27%.
Step-by-step explanation:
From data of survey we can estimate the proportion of the sample whose favorite pizza is pepperoni. That is 40 (say pepperoni is the favorite) from 150 (total of sample).
Proportion would be that is 27%.
Now we can calculate 27% of total of residents (2,800). We should multiply 27% by 2,800.
which is close to 750.
So we can conclude that yes, 750 is a reasonable estimate because the proportion of the sample whose favorite pizza is pepperoni is about 27%
