Answer:
r=−9.403283,−6.348173,0.751456
Step-by-step explanation:
Let's solve your equation step-by-step.
7(r3+15r2+48r−44)=r+6
7r3+105r2+336r−308=r+6
Step 1: Subtract r+6 from both sides.
7r3+105r2+336r−308−(r+6)=r+6−(r+6)
7r3+105r2+335r−314=0
Step 2: Use cubic formula.
r=−9.403283,−6.348173,0.751456
We can simplify the 128 under the fourth root sign. Since 2^4 is 16, and 128 is divisible by 16, we can pull that out of the radical.
There appears to be a very loose negative correlation between the data.
The screenshot is attached of the graph. The data does not form a very tight line, so it is not a strong correlation, but it does appear to generally decrease.
Move the decimal to the left 2 spaces. 90% would .90. 74% would be .74. 134% would be 1.34 Got it? It' always the same no matter the percent. 2 spaces to the left.
