Answer:
Strong positive
Explanation:
In studies, we usually establish relationships between two or more variables using correlations. Correlations tell us how this variables are related.
- Two variables have a positive correlation when if one increases the other increases too.
- Two variables have a negative correlation when if one increases the other decreases and vice versa.
Also, a correlation can be weak, moderate or strong. Researchers agree that a correlation that is larger than 0.70 should be considered a strong correlation.
In this example Isabella reads about a study saying there's a correlation coefficient of +0.85 between hours spent studying and final exam grade. <u>The fact that the sign of this correlation is "+" tells us that it is positive</u> (the more hours spent studying, the better final exam grade). We can also see that <u>the coefficient is 0.85 which is greater than 0.70 and therefore we can consider this correlation as a strong one.</u>
Thus, Isabella would conclude that this is a strong positive relationship.
Answer: C. He must drive at most 7.5 hours the first day.
Explanation: 7.5 x 60 = 450 - 1000 = 550
9.167 x 60 = 550.20 - 1000 = -449.98
(be careful, make sure to select the answer with the answer at most)
If only one country has the virus then the rest of the world would be less affected so it would be easier to get the supplies and resources needed to help that country recover.
