The stingray population in a particular reef is decreasing at a rate of 1.4% per year. the population was 3800 in the year 2008. what is the best prediction of the population in the year 2013? round to the nearest whole number.
show all work

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

i can you with this question sweetie!

step-by-step explanation:

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
