23. To find out whether Chris, Mary Beth, and Allison are in agreement with each other, we just need to find out what the percentage is that we are working on and use what we know to understand if they are in agreement.
Chris says that 46.2% of the votes went to a certain candidate. A percent is the fraction of parts-to-whole represented in a decimal form. A percentage is NOT in decimal form, however. To get a percentage in decimal form, you can either divide the percentage by 100, or (my personal shortcut) just shift the decimal point over two places to the left.
46.2% = 0.462
Based on this, we can see that at least Chris and Allison are in agreement, since Allison said that 0.462 voters voted for the candidate in question.
To find out if Mary Beth stands with them, we just have to divide the amount of people who she says voted for the candidate by the amount of voters in total to get her percentage.
231 / 500 = 0.462
This matches the other two's results, so we can safely come to our conclusion.
YES, Chris, Mary Beth, and Allison are in agreement on the population of voters who voted for the candidate.
Hope that helped! =)
It went up 125% or 25 percent more
Correlation coefficients are expressed by a number between -1 and 1.
If the value is -1 or 1 it indecates a perfect (negative and positive) correlation.
If the value is 0 indicates null correlation.
As the correlation value for you data set is -0.833 it is very close to the -1. It indicates a good correlation in the data. Then, the value you predicted is reasonably close to the actual value.
Answer:
4/9
Step-by-step explanation:
Notice the repeating symbol on top of the 0.4, so instead of 4/10, it would be 0.44444, which is 4/9 if you turn it into a fraction.
