Answer:

Step-by-step explanation:

In the graph, you can observe that all five points are perfectly lined up on a straight line, which is decreasing, because each points is lower than the previous one.

This situation represents a coefficient of correlation of -1, which means there's a strong negative correlation between variable.

Once again, graphically, this strong negative correlation can be deduct from the behaviour of the data, which is clearly decreasing with a straight line behaviour. In other words, the line that best fits is almost unique.

Therefore, the right answer is C.

A classroom has a length of 30 ft. and a width of 20 ft. The flooring is to be replaced by tiles. If each tile has a length of 3

Mashcka [7]

Answer:

100

Step-by-step explanation:

Hello! to calculate the number of tiles needed for the floor you need two things

1. number of tiles that fit across the width, this is achieved by dividing the total width by the width of each tile

Width=20ft=240in

$N1=\frac{240}{24} =10$

2.number of tiles that fit in the logitude, this is achieved by dividing the total length by the length of each tile.

leght=30ft=360in

$N2=\frac{360}{36} =10$

Finally, you multiply the number of tiles that fit in width by the number of tiles that fit in length.

N=10X10=100
