<u>Answer-</u>
<em>-0.9</em><em> represents the strongest correlation</em>
<u>Solution-</u>
Correlation coefficient-
- Correlation coefficient measuring a linear relationship between the two variables indicates the amount of variation of one variable accounted for by the other variable.
- The coefficient of correlation always lies between –1 and 1, including both the limiting values, i.e.
The more closer its absolute value to 1, the stronger the relationship is.
If r is -ve, then the relationship is negative (i.e if one increases then the other must decrease)
If r is +ve, then the relationship is positive (i.e if one increases then the other must increase)
As, in case of -0.9, its absolute value 0.9 is more closer to 1, so it is the strongest correlation (strong-negative correlation)

first off, let's recall that a cube is just 6 squares stacked up to each other, like in the picture below. Since we know its volume, we can find how long each side is.
part A)
part B)
they have a painting with an area of 12 ft², will the painting fit flat against a side? Well, it can only fit flat if the sides of the painting are the same length or smaller than the sides of the crate, we know the crate is a 4x4x4, so are the painting's sides 4 or less?
If the problem looks like mine, the answer is 152.
