I hope I read these correctly....not that easy...u got weird looking x's and ur 4's can almost pass for 6's
The degree of the polynomial will tell you the max amount of zeros you will have. 11 in this case.
However you can also have 9,7,5,3,1 (keep subtracting by 2)
So the answer is 1.
Answer:4 hours
Step-by-step explanation:
6*2=12
12/3=4
The correlation coefficient (r) of the height and weight is 0.40391008.
Rounded, It will be 0.4
That means that the correlation between the height and weight is a positive weak correlation.
