A statistician wants to determine the average annual Gross National Product for countries in Africa. He samples the 20 largest (in terms of population) African countries over 10 years, and gets their quarterly G.N.P results for each quarter of each year. Which one of the following is a true statement concerning the statistician's study?
Answers
Answer:
Step-by-step explanation:
The description provided offers information about the statistician's study. Let's analyze the given scenario and identify the true statement:
Sample Size and Selection:
The sample consists of the 20 largest African countries in terms of population, and data is collected quarterly for each year over a span of 10 years.
Scope:
The study focuses on African countries, particularly the 20 largest by population, providing insights into the continent's economic productivity.
Frequency of Data Collection:
Data is collected quarterly for each year over a period of 10 years, resulting in a substantial amount of data for analysis.
Based on this information, a true statement concerning the study could be:
True Statement:
"The study aims to analyze the quarterly Gross National Product (G.N.P) of the 20 largest African countries, focusing on economic productivity over a span of 10 years."
This statement accurately captures the objective, sample size, data collection frequency, and scope of the study.

Answer:
45 is the nearest whole number.
Step-by-step explanation:
You look at the first decimal when rounding to the nearest whole number.
4 or less let it rest
Example: 36.2
2 is less than 4 so you let it rest and the nearest whole number would be 36.
5 or more raise the score
Example: 36.6
6 is 5 or more so you raise the score and the nearest whole number would be 37.

the smaller number is 8, and the larger number is 12, and they indeed add up to 20, and three times the smaller number (3 * 8) is equal to two times the larger number (2 * 12).
Let's call the two numbers x and y, with x being the smaller number and y being the larger number.
We have two pieces of information from the problem:
1. The sum of the two numbers is twenty:
x + y = 20
2. Three times the smaller number is equal to two times the larger number:
3x = 2y
Now, we can solve this system of linear equations.
First, we can solve equation (1) for x:
x = 20 - y
Now, substitute this expression for x into equation (2):
3(20 - y) = 2y
Now, distribute the 3 on the left side:
60 - 3y = 2y
Now, isolate the variables on one side of the equation and constants on the other side:
60 = 2y + 3y
Combine like terms:
60 = 5y
Now, divide by 5 to solve for y:
y = 60 / 5
y = 12
Now that we have found the value of y, we can substitute it back into equation (1) to find x:
x + 12 = 20
Subtract 12 from both sides:
x = 20 - 12
x = 8
So, the two numbers are:
x = 8 (smaller number)
y = 12 (larger number)
Therefore, the smaller number is 8, and the larger number is 12, and they indeed add up to 20, and three times the smaller number (3 * 8) is equal to two times the larger number (2 * 12).
