Answer:
1.4% is the maximum acceptable annual rate of growth such that the population must stay below 24 billion during the next 100 years.
Step-by-step explanation:
We are given the following in the question:
The exponential growth model is given by:
where k is the growth rate, t is time in years and 
is constant.
The world population is 5.9 billion in 2006.
Thus, t = 0 for 2006
We have to find the maximum acceptable annual rate of growth such that the population must stay below 24 billion during the next 100 years.
Putting these values in the growth model, we have,
1.4% is the maximum acceptable annual rate of growth such that the population must stay below 24 billion during the next 100 years.
Answer:
Pr(X >42) = Pr( Z > -2.344)
= Pr( Z< 2.344) = 0.9905
Step-by-step explanation:
The scenario presented can be modeled by a binomial model;
The probability of success is, p = 0.65
There are n = 80 independent trials
Let X denote the number of drivers that wear a seat belt, then we are to find the probability that X is greater than 42;
Pr(X > 42)
In this case we can use the normal approximation to the binomial model;
mu = n*p = 80(0.65) = 52
sigma^2 = n*p*(1-p) = 18.2
Pr(X >42) = Pr( Z > -2.344)
= Pr( Z< 2.344) = 0.9905
Answer:
4 mph
Step-by-step explanation:
yard → mile = divide the length value by 1760
7040 / 1760 = 4 miles per hour
Answer:
Option A is the correct answer.
Step-by-step explanation:
The sum of interior angles of a polygon is given by (n-2) x 180°, where n is the number of sides.
The sum of interior angles will not affect irregularity of polygon, it is same for regular and irregular polygon.
For a pentagon n =5.
Sum of interior angles = (5-2) x 180 = 3 x 180 = 540°
Option A is the correct answer.
A=wl, so the answer is A :)
