Answer:
it can not be made into a regular fraction. but it can be made into a whole number. the whole number would be 710
Step-by-step explanation:
The solution to your problem is as follows:
Given:
P₀ = 5,642×10^6 people,
i = 1.3% = 0.013 per year,
n = 2020 - 1994 = 26 years,
We get:
<span>
Pn = P₀ e^(i.n) </span>
. . .= 5,642×10^6×e^(0.013×26)
<span>. . .= 7,911×10^6 people
Therefore, the </span>the world's predicted population in the year 2020 is <span>7,911×10^6 people.

Answer: 
Step-by-step explanation:
Given : The speeds of vehicles traveling on a highway are normally distributed .
Standard deviation: 
Since , sample size : 
, which is small sample (n<30) so the test applied here is a t-test.
Degree of freedom= 
Sample mean : 
Level of significance : 
Then , significance level : 
Using t-distribution table , Critical value : 
The confidence interval for population mean is given by :-
Hence, a 98% confidence interval for the population mean=
