The function models the number of accidents, f(x), per 50 million miles driven as a function of a drivers age, x, in years, where x includes drivers from ages 16 through 74, Inclusive. Find and interpret f(63)

F(x)=0.4x^2-36x+1000

F(63)=

Interpret f(36).

For ? - year old drivers, there are ? Accidents per 50 million miles driven.

Identify this information as a point of the graph of f ?

42

step-by-step explanation:

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;

no
