aksik [14]

Answer:

$= -2x^2 +4x+ 16$

Step-by-step explanation:

From the given equation:

$(x+ 2 ) \ and \ (-2x +8)$

As a single equation, we have:

$= (x + 2) \ \times \ ( -2x + 8) \ = 0$

open brackets

$\implies -2x^2 +8x +(-4x) + 16$

$= -2x^2 +4x+ 16$

What is the probability of throwing a number greater than 4 when rolling a number cube that has sides labeled 1, 2, 3, 4, 5, 6?

Leona [35]

What is probability rolling a number greater than 4?

The only numbers there are is 5 and 6.
That means that there are 2 outcomes out of 6 total outcomes.
That would be 2/6.
Divide the the top and bottom by 2.
In simplest form it would be 1/3.
2/6=1/3

The answer is 1/3. The probability of throwing a number greater than 4 is 1/3.
