After Rob has lost, he will have 120 dollars. We can work this out by
establishing that if Rob had 280 dollars before the final competition,
and the ration at the point was 4 to 7, then this means that Tom must
have had 4/7 of what Rob had, so x=4/7 * 280, x = 4 x 40, x = 160. This
means that Tom had 160 dollars and Rob had 280. Adding this together
they have a combined 440 dollars, but the ratio is now 8:3. There are 11
parts to the ration, due to the fact that 8 and 3 is 11, so we need to
work out one part of the ratio - 440 divided by 11 equals forty. This
means that Tom has 8 multiplied by 40 (320 dollars) and Rob has 40
multiplied by 3, so 120 dollars.
Given:
Each side of the cube shaped box = 
To find the surface area of the box and the volume of the box.
Formula
If the each side of cube is a,
- Its surface area
- Its volume
Now,
Putting 
we get,
The surface area, 
sq unit
sq unit
sq unit
And,
The volume, 
cube unit
cube unit
Hence,
The surface area of the box is 
sq unit and
The volume of the box is 
cube unit.
Answer:
The correct answer is the scatter plot which has a strong positive slope of the curve of best fit.
Step-by-step explanation:
A scatter plot shows a relationship between two variables for a particular individual. It is actually a graph where we draw a curve of best fit which can represent the whole data. A scatter plot having the correlation coefficient closest to r = 1, is said to have a very strong correlation between the variables.
A scatter plot would have a strong correlation if the data points of the individual are very close to the line or curve of best fit.
For r = 1 , the correlation is strong and positive.
