The population after 3 years would be 8.20 millions.
Step-by-step explanation:
Given,
Initial population = I = 4.2 million
Growing rate = r = 25%
If the initial population and growing rate is given, the formula to calculate the population (x) after n years would be:

By putting the values in the equation, we get

The population after 1st year (x1) would be

x1 = 5.25 million
Similarly,

x2 = 6.56 million

x3 = 8.20 million
Hence, the population after 3 years would be 8.20 millions.
But, if you are asking about the total population at that time. It would be
I + x1 + x2 + x3 = 24.21 million
Answer:
a) The probability that all five are brand A is 0.0288
b) The probability that exactly two bottles are brand A is 0.0288
c) The probability that none of the bottles is brand A is 0.0048
Step-by-step explanation:
We have 9 bottles of brand A and 7 bottles of brand B.
The total of bottles is 16.
a) The probability that all five bottles are brand A is given by:

b) Since we have 9 bottles of brand A we calculate the probability of picking two brand A bottles and the we calculate the probability of picking 3 brand B bottles:

c) The probability that none of the bottles is brand A is the same as picking 5 brand B bottles:

Answer:
Graph #1 - y=-20x+40
Graph #2 - y=5x+10
Step-by-step explanation: The first thing that you do is pull two points from each of the graphs and find the slope. To find the slope you use
<h2>
M = y2-y1/x2-x1</h2>
<u>FROM GRAPH #1:</u>
<h3>(3,40) (2,80)</h3>
(x1,y1) (x2,y2)
80-40/2-3
20/-1
M = -20
<u>FROM GRAPH #2:</u>
<h3>
(1,10) (3,20)</h3>
(x1,y1) (x2,y2)
20-10/3-1
10/2
M = 5
2. Now once you find the slope you will use the equation of a line formula to form an equation.
<h2>
y=mx+b</h2>
The (mx) is your slope, the (b) is the y-intercept. (any value on the y-axis)
3. Since we now know the equation of a line and the slope we will substitute the variables.
<u>Graph #1:</u>
y=mx+b
y=-20x+40
<u>Graph #2:</u>
y=mx+b
y=5x+10
