Answer:
Population = All registered voters in Raleigh city
Population size = 9500
Sample size = 360
Proportion of sample statistic for brown = 0.3167
3008 voters
Step-by-step explanation:
Population refers to all elements which meets the requirement for a specific experiment or research interest.
Number of voters for brown = 114
Number of voters for Feliz = 210
Undecided = 36
Sample statistic for proportion in support of brown :
Proportion = x / n
x = number who said they'll vote for brown
n = sample size
Sample statistic for proportion in support of brown = 114 / 360 = 0.3167
Using the proportion ; number from population who'll vote brown :
Sample proportion * population size
0.3167 * 9500 = 3008 voters
Answer:
db / dt = kb
this becomes b(t) = Ce^(kt)
C = 100, the initial population
P(1) = 420 = 100 e^(1k)
4.2 = e^k
ln 4.2 = k
a) thus, b(t) = 100 e^(t ln 4.2)
b) b(3) = 100 e^(3 ln 4.2)
c) growth constant will still be ln 4.2 (constant percentage of populatioin)
d) 10000 = 100 e^(t ln 4.2)
100 = e^(t ln 4.2)
ln 100 = t ln 4.2
t = ln 100 / ln 4.2
Step-by-step explanation:
Combine like terms and then simplify
