Answer:
- R= 0.2
- 2
Step-by-step explanation:
explaining the answer to 1
I'll explain everything so you understand.
The correlation coefficient tells us about the strength of the relationship between the variables. In other words, it tells us how well the data fits on the line of best fit.
So, the closer the points lie on the line of best fit the stronger the relationship and correlation.
The further the points lie from the line of best fit, the weaker the correlation
It is important to note that the correlation coefficient (r) always lies between -1 and 1.
So, the closer the value of r lies to -1 or 1 the stronger the relationship between the variables.
The closer the value of r is to 0 the weaker the relationship between the variables and the weaker the correlation.
explaining the answer to 2
the correlation coefficient (r) always lies between -1 and 1 so it can't be 2.
Hope this helps.
Answer: Yesterday it rained longer
335 / 60 = Hours
335 minutes
= 5 7/12 hours
≈ 5.58333 hours
335 minutes
= 5 hours & 35 minutes
Hope it helps and have a good day! (:^w^:)
Shannon did not mix the correct shade. Cause the correct ratio of blue and red is 7:5. While Shannon mix 12:8=3:2 which is not equal to 7:5.
Answer:
B. y = (x + 3)^2 - 17
Step-by-step explanation:
When Andy completes the square, he adds and subtracts the square of half the x-coefficient. That is, he adds and subtracts (6/2)² = 9:
... y = x² +6x +9 -8 -9
... y = (x² +6x +9) -17
... y = (x +3)² -17 . . . . . . . . matches selection B
