Answer:

6 green marbles should be added.

Step-by-step explanation:

If the probability of drawing a blue marble from 18 marbles is 2/3 then there are 12 blue marbles because 18 times 2/3 is 12. This means that to reduce this probability to 1/2 you need to add 6 more marbles to the total amount to get it to 24. Now the probability of getting a blue marble is 12/24 which is 1/2.

What is the range of the translated function? {y|y < 0} {y|y ≥ 0} {y|y is a natural number} {y|y is a real number}
zmey [24]

The Range of the function is  {y|y is a real number} , Option D is the correct answer

<h3>What is Range ?</h3>

Range of a function is all the value a function can obtain.

From the figure it can be seen that the graph is moving slowly in either direction.

It extends from -∞ to +∞ ,

Therefore ,  {y|y is a real number} , Option D is the correct answer.

The complete question is

The graph shows a vertical translation of y = ³√x

What is the range of the translated function?

{y|y < 0}

{y|y ≥ 0}

{y|y is a natural number}

{y|y is a real number}

The image of the translated function is attached.

Which are the domain, range, and asymtope of h(x)=2x+4
Serggg [28]

h(x) = 2x + 4   is a line so it has infinite domain and range and no asymptotes.

D: {x ∈ R | -∞ < x < ∞ }    Interval Notation: (-∞, ∞)

R: {y ∈ R | -∞ < y < ∞ }    Interval Notation: (-∞, ∞)

Asymptotes: None
