There are 16 possible outcomes.

Step-by-step explanation:

For this question, we combine the possibilities together.

R = red G = green O = orange B = blue

There are 16 possible outcomes.

You can also find the total number of possible outcomes by using the formula for permutations. n is the total number of choices. r is the number you are examining.

$\frac{n!}{(n-r)!}$

$\frac{4!}{(4-2)!} =12$

This number doesn't include the outcome of having the same color twice. There are four colors meaning that their four outcomes in which the same color is spun twice.

12 + 4 = 16

Given h of x equals negative 2 times the square root of x minus 3 end root, which of the following statements describes h(x)?

MrMuchimi

Answer:

The function h(x) is decreasing on the interval (3, ∞).

Step-by-step explanation:

Please take a look at the attached image.

You will see a graph of the given function h(x) = -2 $\sqrt{x-3}$ . The function is decreasing.

The function starts at 3 and starts to go towards negative infinity on the x-axis. Therefore the function is decreasing on the interval (3, ∞).
