Answer:

Mean = 11.8

Step-by-step explanation:

Given the following data;

Total number of cars (n) = 5

Number of cars (x) = 1, 2, 3, 4, 5

Frequency (F) = 5, 10, 7, 2, 1

F(x) = (1*5) + (2*10) + (3*7) + (4*2) + (5*1)

F(x) = 5 + 20 + 21 + 8 + 5

F(x) = 59

To find the mean;

Mean = F(x)/n

Mean = 59/5

Mean = 11.8

Answer:

(1.06)0 = 1 and positive powers of 1.06 are larger than 1, thus the minimum value N(t) attains, if t≥0, is 400.

From the point of view of the context, a CD account grows in value over time so with a deposit of $400 the value will never drop to $399.
