Acompany just purchased a fleet of new cars for $30,500 per car. it is estimated that value of each car will depreciate by $4500 per year. let x be the age of the car in years, and y be the value of the car. write an equation that estimates the value of the car as a function of its age.

The required equation is ,

y =

Step-by-step explanation:

Current value of each car = $ 30,500

Each car's value depreciate by $ 4500 per year.

If x is the age of the car in years then it's value will be,

y =    [in $]

8 2/3 is the answer

step-by-step explanation: just use a calculator

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;
