Answer:
<h2><em>
$23.5</em></h2>
Step-by-step explanation:
Gene is playing a game with a bag of marbles. If 3 of the marbles are blue, 4 are green, and 7 are yellow and awarded prices for the marbles are $2 green $0.5 yellow $4 blue, the expected payout for Gens game is expressed as shown;
If a blue marble costs $4, 3 blue marbles will cost 3*$4 = $12
If a green marble costs $2, 4 green marbles will cost 4*$2 = $8.0
If a yellow marble costs $0.5, 7 yellow marbles will cost 7*$0.5 = $3.5
Total payout for Gene's game will be the equivalent to $12+ $8 + $3.5 = $23.5.
<em>Hence Gene expected cost will be $21.5</em>
A function is increasing if it "points upwards".
Think that you have two inputs 
(think of them as being very close to each other). A function 
is increasing if
So, smaller input, smaller output.
So:
- In the first segment on the left, the function is decreasing: if you move with little steps rightwards, the output will get smaller and smaller (the function points to the right bottom)
- In the second segment, the line is constant (it's horizontal). This means that even if you consider a larger input, the output reimains the same
- In the third segment, the function is increasing: if you consider a larger input, the output will be larger as well: the function points to the top right.
- In the fourth segment, the function is decreasing again (look at the first bullet point)
So, the function is increasing in the third segment, which is delimited by

Answer:
Natasha gets 84
Step-by-step explanation:
Here, we want to know how much Natasha gets
Krutika gets 2 times as much as Natasha
If Natasha gets x, Krutika gets 2x
If Natasha gets x, Richard will get x/3 ( 3 times of this is what Natasha gets)
Now let us have a ratio;
K : N : R
2x : x : x/3
Multiply through by 3
6x : 3x : x
To get the amount Natasha gets, we add up all ratio; (6x + 3x + x ) = 10x
Natasha gets 3x of the total ratio
That will be;
3x /10x * 280
= 3/10 * 280
= 84
