If a variable does not have a coefficient then it is either a 1 or a -1. true or false

True

Step-by-step explanation:

If the coefficient is -1 then the variable will have a negative sign in front of it.

Example: (-x)

If the coefficient is 1 then the variable will stand alone.

Example:  (x)

True

Step-by-step explanation:

An example of a variable "without" a coefficient is x or -x. There is no number beside x, meaning there is no visible coefficient. And when there is no visible, coefficient, the variable is multiplied by 1 or -1 (the negative sign determines whether the variable is negative or not).

no

step-by-step explanation:

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12
