Here are the answers
Zeros: x= -3/2 x=-3
It is 42,44, and 46. If you add them all together you get 132 :)
They are stupid. correlation is always between -1 and +1
You can't. Knowing the volume doesn't tell you the dimensions.
There are an infinite number of different rectangular prisms, all
with different dimensions, that all have the same volume.
Here's an example. Let's say I have a rectangular prism and its
volume is 64.
The dimensions could be . . .
1 x 1 x 64
1 x 2 x 32
1 x 4 x 16
1 x 8 x 8
2 x 2 x 16
2 x 4 x 8
4 x 4 x 4 .
If I only tell you the volume, there is no way to figure out the dimensions.
Answer:
Number : 42
Step-by-step explanation:
This number will be a two - digit number, and hence we can say that it is yz. The ratio of the units digit to the tens digit is given by 1 / 2, so z / y = 1 / 2.
In addition the tens digit is 2 more than the units digit, so y = z + 2. We therefore have the following system of equations,
y = z + 2,
z / y = 1 / 2
Substituting the first equation into the second we receive z / z + 2 = 1 / 2. Using this we can solve for z.
z / z + 2 = 1 / 2 ( Cross - Multiply )
z + 2 = 2z, z = 2
And knowing z we can solve for y. y = z + 2 = 2 + 2 = 4. Therefore our number is 42.
