Answer:

Step-by-step explanation:
You can solve this equation with the quadratic formula which is:

All you need to do is rearrange the equation (add
to both sides and then multiply both sides by 2) to get:

From this new equation, we can easily see that a = 2, b = -5, and c = 11 AND you don't have to work with as many fractions. Substitute the values for a, b, and c into the quadratic formula to get:

That simplifies to:

Which simplifies even further to:

Which gets you:

P.S. The plus-minus sign wasn't working for me, so I had to just write, "+or-". I hope that didn't make it too confusing for you.
P.P.S. Hope this helps :) Don't forget to mark Brainliest if it did.
Answer:
The best estimate of the correlation coefficient is 0.9 from the given data.
Step-by-step explanation:
From the scatter plot, the line of best fit will have a positive slope.
So, the correlation coefficient ,
is greater than 0.
so,
≠ - 0.9
Also, there is a deviation from absolute linearity.
So,
≠ 1
Again from the scatter plot it is closer to linearity than further.
Hence,
≠ 0.3 .
So
= 0.9
- 30m^2 - 10m + 30
distribute your negative 10, you will first get 30m, then - 30m^2.
next distribute the negative 5, you will get - 40m, then 30.
combine like terms, and make sure its in standard form, - 30m^2 - 10m + 30
