-0.8 would be the best estimate.
The data seem to have a negative correlation, since they are decreasing; this means our r-value will be negative.
Our two negative choices are -0.25 and -0.8. -0.8 would be a fairly strong correlation, whereas -0.25 would be a weak correlation. The data do seem to be fairly strongly related, so we will use -0.8.
Answer:
47, 61, 76
Step-by-step explanation:
1 to 11 is 10, 11 to 22 is 11, 22 to 34 is 12. So you are increasing what you are adding by 1. So next you'd add, 13, 14, and 15 respectively. 34+13 is 47, 47+14 is 61, and 61+15 is 76.
Answer:
39.4 divided by (-7.2)= -5.472
6.7-39.31=-32.61
Step-by-step explanation:
Answer:
3
Step-by-step explanation:
term of degree 4 is the term with the exponent of 4
3x^4 is the term of degree 4 so the coefficient is 3
