Answer:
C
Step-by-step explanation:
The sequence is arithmetic with n th term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 1 and d = 3, thus
= 1 + 3(n - 1) = 1 + 3n - 3 = 3n - 2 → C
The local Toyota dealership pays an average of $9,260 with a standard deviation of $1099 for used car trade-ins. They sell new c
ars at an average of $28,451 with a standard deviation of
$3392. Assume independence of new car and trade-ins. What are the mean and standard
deviation of the revenue this dealership should expect when a person trades in a car and purchases a new one?
