First we define the variables:
p = population
t: time in years
The equation that best fits this problem is a linear equation of the form:
p = -4t + 25
Note that for t = 0 the value of p is 25, which represents the initial population.
Answer:
a function for the population size, p, at time t is:
p = -4t + 25
M = ( (-6+4)/2, (3+-2)/2 )
M = (-1, 1/2)
Answer:
c (-4,3)
Distance between points 3.5

Answer:
Step-by-step explanation:
A. In each drawing, the odds of choosing green is 7 / (7 + 13 + 9) = 7/29
with replacement, the odds in each drawing are the same
7/29•7/29•7/29 = 7³/39³ = 343 / 24,389
B.
Odds of drawing all non black balls is the sum of odds of drawing the following possible patterns
ggg + ggr + grg + rgg + rrg + rgr + grr + rrr
(7•6•5 + 7•6•9 + 7•9•6 + 9•7•6 + 9•8•7 + 9•7•8 + 7•9•8 + 9•8•7) / 29•28•27 = 3,360/21,924
