The bird population on an island is declining at a rate of 2.2% per year. If the population was 3500 in the year 2009, which is

the best prediction of the population in the year 2014? 3500 in 2009
3500 (.022) = 77
3500 - 77 = 3423
3423 in 2010
3423 (.022) = 75.31
3423 - 75.31 = 3347.69
3347.69 in 2011
3347.69 (.022) = 73.65
3347.69 - 73.65 = 3274.04
3274.04 in 2012
3274.04 (.022) = 72.03
3274.04 - 72.03 = 3202.01
3202.01 in 2013
3202.01 (.022) = 70.44
3202.01 - 70.44 = 3131.57
3131.57 in 2014

Given:
2009 : 3,500 population
decrease of 2.2% per year. 
100% - 2.2% = 97.8%

2014 - 2009 = 5 years

3,500 * (0.978)^5 = 3,500 * 0.89473 = 3131.57

The bird population in 2014 will be 3,131.57 or 3,132.

From an airplane at an altitude of 1200m the angle of depression to a building one the ground measures 28 degrees. Find the dist
Inessa05 [86]

Check the picture below.

now, we're assuming "to the building" means "to the ground", since we don't know the building's height, so we're also assuming the 1200m is above the building, as you see in the picture.

make sure your calculator is in Degree mode.

melomori [17]

Answer:

0.288

Step-by-step explanation:

Calculation for what is the probability that exactly 2 of them will be baskets

In order for us to find the probability that exactly 2 of them will be baskets we would have to make use of binomial distribution using Microsoft Excel

P =4 baskets/10 shots=0.4,

x = 2

n = 3 shots

P(2)=BINOMIAL DISTRIBUTION(2,3,0.4,FALSE)

P(2)=0.288

Therefore the probability that exactly 2 of them will be baskets is 0.288
