For country A , the doubling time = 26
For country B , the growth rate = 1.5
Define growth rate?
The growth rate is the fractional change per unit time, ∆x. x. ∆t , the fractional change divided by the length of the time period.
For Country A :
Formula for doubling time,
T = [tex]\frac{log 2}{log (1 + \frac{k}{100} )}[/tex]
The given growth rate , k% = 2.7%
T = [tex]\frac{log 2}{lod (1 + \frac{2.7}{100} )}[/tex]
= [tex]\frac{log 2}{log (1 + 0.027)}[/tex]
= [tex]\frac{log 2}{log (1.027)}[/tex]
= 26.017
≅ 26
Therefore, the doubling time (T) = 26 years
For Country B :
Formula for growth rate
k = 100 [tex][2^{1/T} - 1][/tex]
k = 100 [tex][2^{1/46} - 1 ][/tex] (Since T = 46 years)
k = 100 [1.01518 - 1]
k = 100 [0.01518]
k = 1.518
k ≅ 1.5
Therefore, the growth rate is 1.5 % per year.

What are fit equations?Fitting an equation to data is finding a linear, quadratic, exponential, or any other sort of function whose graph includes, or comes as close as possible to, a given set of data in the form of ordered pairs. The relative predictive power of a model shows how accurately the model is related to the data.
The theoretical pattern best accounts for the relationships among variables in a data set. For example, a regression equation having the best fit to sample data is the one that minimizes differences between observed and predicted values.

What is the better deal? 6 for $6.99 or 24 for $13.99
Answers
13.99/24=.58
Therefore better to buy more as the unit price per item is cheaper
Answer:
24 for $13.99
Step-by-step explanation:
Find the cost of 1 for both deals.
6 for $6.99. Divide 6.99 with 6:
6.99/6 = 1.165
~$1.17 for one.
24 for $13.99. Divide 13.99 with 24:
13.99/24 = ~0.582
~$0.58 for one.
24 for $13.99 is the better deal, by ~59¢.

An object travels along a horizontal straight path at a constant rate. The object travels 1/2 of the
length of the path in 3/4 second. At that rate, how many seconds does it take the object to travel the
entire length of the path?
Answers
Answer:
1.5 seconds
Step-by-step explanation:
Given that,
The object travels 1/2 of the length of the path in 3/4 second.
We need to find the time it takes the object to travel the entire length of the path.
1/2 of length = 3/4 seconds
Entire length,

So, it will take 1.5 seconds to cover the entire length of the path.
