Answer:
Step-by-step explanation:
Japan 80.09 = 16.018
Switzerland 75.81 = 15.162
[(105 - 84) / 84] × 100 =
= [(21) / 84] × 100 =
= 0.25 × 100 = <u>25%</u>
Answer:
1:2
Step-by-step explanation:
1:n to 6:12
Take the second term 6:12
Divide each term by 6 to get to 1
6/6 =1
Divide all terms by 6
6/6 : 12/6
1:2
n=2
Answer:
With a correlation coefficient of 0.109 you can not be confident at all; this is about as close to a random guess you could get.
Step-by-step explanation:
Lines of best fit are used to try to make a correlation (relationship) about data that will either be positive (uphill), negative (downhill) or no correlation (points are scattered). Correlation coefficients based off of a line of best fit will fall between -1 and +1 where -1 would represent a perfect negative relationship and +1 would represent a perfect positive relationship. A correlation coefficient of 0 would indicate that there is no relationship. So, if your data shows a correlation coefficient of 0.109, which is closest to 0 on a number line, then you can't be sure that your data has a very close relationship.
