3541

Step-by-step explanation:

This is compound interest problem.

This takes the formula:

Where F is the future value (we want this, the population at 2013)

P is the present value (P=3800)

r is the rate of decrease (1.4% = 0.014)

t is the time frame in years (t = 5, from 08 to 13)

Putting these, we get the

Rounded to nearest whole number, the population would be around 3541

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.

spinner 1 spinner 2

1                     1

1                     2

1                     3

1                     4

2                   1

2                   2

2                   3

2                   4   = not 1, and 4

3                   1

3                   2

3                   3

3                   4 = not 1, and 4

only 2 outcomes have passed the given condition.
