Answer:

"6 out of 10 people" means the ratio of class:no_class is 6:4

990/10 = 99, the smallest the "class" and the "no_class" add up to is 10. And, generally, the total divides with that nicely, as in this case.

99(6) = 594 ----------- probably class

99(4) = 396 ------------------ probably no class

Total  = 990

I hope this helps

Is the following linear, exponential, or neither? 3,6,9,12,15,18...
Bas_tet [7]

Given:

3,6,9,12,15,18...

We need to find the difference.

The difference between 3 and 6 is 6-3 =3.

The difference between 6 and 9 is 9-6 =3.

The difference between 9 and 12 is 12-9 =3.

The difference between 12 and 15 is 15-12 =3.

The difference between 15 and 18 is 18-15 =3.

Recall that linear have equal differences.

We get an equal difference between each value.

The form of the equation is

y=3x

Hence the given is linear.

What's the error? Jerry says that a cube with edges that measure 10 cm has a volume that is twice as much as a cube with sides t
disa [49]
The quick way to dispute something like this is to simply do the calculation and then create a ratio. 

Cube One (Large Cube)
The formula for a cube is V = e^3 
e = the measurement of an edge. In this case.
e = 10 cm
V = e^3
V = 10^3 = 10*10*10
V = 1000 cm^3

Cube 2 (Small Cube)
V = e^3
e = 5 cm
V = 5*5*5
V = 125 cm^3

Ratio
Large Cube / Small Cube = 1000 / 125 = 8/1.

The difference in size is 8 to 1 not 2 to 1.

Explanation
He's right if he sticks to one side. The ratio of one side of the large cube to the small one is 2 to 1. But once you put that into the formula for volume, three sides are multiplied together and that 2 shows up everytime you multiply the sides together.
