i.
Calculate percent as a fraction for each continent.
i.

Answer to Problem 44PPS
Asia, 59.4% = 0.594
Africa, 14.2% = 0.142
Europe, 12.3% = 0.123
North America, 7.9% = 0.079
South America, 5.7% = 0.057
Australia, 0.5% = 0.005
Explanation of Solution
Given:
Calculation:
Here, we have to convert percent as a fraction. When any number is divided by 100, then decimal point moves to left of the number.
We have percent of population for each continent,
For Asia,
For Africa,
For Europe,
For North America,
For South America,
For Australia,
Conclusion:
Thus, we are able to convert percent of population of given continent into fraction.
ii.
Calculate fraction of population in Americas.
ii.

Answer to Problem 44PPS
Fraction of population in Americas is 0.136
Explanation of Solution
Given:
Calculation:
Here, we have to consider population of north and south America.
Percent population in America is,
North America, 7.9%
South America, 5.7%
Total population in Americas = 7.9%+5.7% = 13.6%
Total population of America in fraction is given as,
Conclusion:
Therefore, we can calculate fraction of population of America from percent population.
iii.
Calculate total population in Asia.
iii.

Answer to Problem 44PPS
Total population in Asia is 3.861 billion.
Explanation of Solution
Given:
World population = 6.5 billion
Calculation:
We have world population equals to 6.5 billion.
Percent population in Asia is 59.4
Hence, total population in Asia can be determined by,
Conclusion:
Therefore, we can calculate total population of Asia from its percent population and world population using simple fraction method.

- You are provided with three 2D data points, p1, p2 and p3. Solving A C = B for C provides youwith the coefficients of a natural cubic spline curve that interpolates these points.Additionally, you have been given A and B, but some elements are missing. Moreover, the last two rowsof A are entirely absent. Your task is to determine and fill in the missing elements. For the last two rows,enforce a zero tangent at the beginning (in p1) and a not-a-knot boundary condition in p2. The matricesA and B are given as follows:Explain how to find the entries of A and B . How would you adapt these matrices if the data pointswere 3D? What if your spline should go through five data points? How many “extra rows” would there thenbe (with “extra” meaning “in addition to securing C2-continuity”)?arrow_forwardWhich graph represents f(x) = √x-2+3?arrow_forwardPractice Assignment 5.6 Rational Functions M Practice Assig Practice Assignment 5.6 Rational Functions Score: 120/150 Answered: 12/15 Question 10 A Write an equation for the function graphed below 5 + 4 1 2 H + + -7 -6 -5 -4 -3 -2 -1 2 34567 | -2 ర y = Question Help: Video Message instructor Post to forum Submit Questionarrow_forward
