P(both red)=(10/17)(9/16)
P(both blue)=(7/17)(6/16)

P(both same)= sum of above 2 = (90+42)/(16*17)=132/(16*17)=<span>0.485

coz both same means both blue or both red

The florida manatee population is 3,000 and is decreasing by 11% each year. Write a function for this situation.

True [87]

Answer:

$P=3000(0.89)^t$

Step-by-step explanation:

It was given that, florida manatee population is 3,000 and is decreasing by 11% each year.

We want to write a function for this situation.

Since the population is decreasing annually, it is modelled by:

$P=P_0(1-r\%)^t$

We substitute the give initial population and rate of decrease to get:

$P=3000(1-0.11)^t$

This simplifies to:

$P=3000(0.89)^t$
