Answer:
C=6p
Step-by-step explanation:
The cost (c) will be by itself since that is the answer you are looking for. 6p is grouped together because for every pound you pay $6. For example if you had 2 pounds of chocolate. You would multiple $6 by 2 and your cost would equal $12

Step-by-step explanation:
17.7+8.3+13.0+2090=24.805g

Properties of Correlation Coefficient,
1- A positive correlation means that if one variable gets bigger, the other variable tends to get bigger.
2- A negative correlation means that if one variable gets bigger, the other variable tends to get smaller.
As in this graph x increases y gets decreased, so it is a negative co-relation. And the points are scattered more the line, so it is a moderate negative co-relation graph. (Please follow the attached picture herewith)
its like 19.25 because thats the anwser and deal with it
For starters,
tan(2θ) = sin(2θ) / cos(2θ)
and we can expand the sine and cosine using the double angle formulas,
sin(2θ) = 2 sin(θ) cos(θ)
cos(2θ) = 1 - 2sin^2(θ)
To find sin(2θ), use the Pythagorean identity to compute cos(θ). With θ between 0 and π/2, we know cos(θ) > 0, so
cos^2(θ) + sin^2(θ) = 1
==> cos(θ) = √(1 - sin^2(θ)) = 4/5
We already know sin(θ), so we can plug everything in:
sin(2θ) = 2 * 3/5 * 4/5 = 24/25
cos(2θ) = 1 - 2 * (3/5)^2 = 7/25
==> tan(2θ) = (24/25) / (7/25) = 24/7
