Question

What was the approximate number of mobile cellular subscriptions per 100 people in Zimbabwe in 2003?

Answer 1

Answer:

B. 4

Step-by-step explanation:

Given exponential model that shows the number of mobile cellular subscriptions per 100 people in Zimbabwe since 2000,

$y=a b^x$

Where,

a=1.067905095

b=1.501755837,

$\implies y=1.067905095(1.501755837)^x$

Since, the number of years from 2000 to 2003 = 3,

Thus, for finding the number of subscriptions in 2003,

x = 3,

Hence, the number of mobile cellular subscriptions per 100 people in Zimbabwe in 2003 is

$y=1.067905095(1.501755837)^3=3.61685122094\approx 4$

Option 'B' is correct.

Answer 2

The answer is 4 when you plug in the equation and solve it equals 4
