This Might Not Be correct But...
If your trying to find X it would be 6.25
You would divide 24 by 1.6 to get 15 so you would divide 10 by 1.6 to get 6.25
So I think Its 6.25 Sorry If im wrong.
Price of DVD player ≥ $150
Saved = $80
Amount needed = $150 - $80 = $70
Saving per week = $10
Let x be the number of weeks needed:
80 + 10x ≥ 150
10x ≥ 150 - 80
10x ≥ 70
x ≥ 70 ÷ 10
x ≥ 7
Answer: She needs to save for for at least 7 weeks.

Answer:
It would most likely be 0.9.
Step-by-step explanation:
The correlation coefficient ranges from -1 to 1 and is dependent on how strong the correlation is between the points. It cannot be 1.2 as it is above one and it cannot be 1 because all the points do not line up on the line of best fit. However, most do, so we can assume that there a strong positive linear relationship which means 0.9 would be the correct answer. The close r gets to zero means the less of a correlation there is. The line of best fit isn't negative so it cannot be -0.23 and it has a strongly positive correlation, not a weak one so it isn't 0.13.
