in total there are 6,4,8 which equals 18 .There are 18 balls in total. but Alex removed 3 so now there are 15 balls. There 3 different colors and 15 balls. So there is a 5% out of 15 that you will get a certain color .To find the probability you need to calculate all the possible outcomes.
G=Green R=Red P=Purple
G,R,P
G,P,R
P,G,R
P,R,G
R,P,G,
R,G,P
There is 6 different outcomes, 15 balls and a 5% chance to get a certain color so if you want to exactly get G,R,P there is a (15 divided by 6) chance to get that order.
(I'm not good at calculating that part.)
Answer:
You are given:
4Fe+3O_2 -> 2Fe_2O_3
4:Fe:4
6:O_2:6
You actually have the same number of Fe on both sides, The same is true for O_2 so yes this equation is properly balanced.
For added benefit consider the following equation:
CH_4+O_2-> CO_2+2H_2O
ASK: Is this equation balanced? Quick answer: No
ASK: So how do we know and how do we then balance it?
DO: Count the number of each atom type you have on each side of the equation:
1:C:1
4:H:4
2:O:4
As you can see everything is balanced except for O To balance O we can simply add a coefficient of 2 in front of O_2 on the left side which would result in 4 O atoms:
CH_4+color(red)(2)O_2-> CO_2+2H_2O
1:C:1
4:H:4
4:O:4
Everything is now balanced.

Answer:
$1.37/lb
Step-by-step explanation:
5.48/4
The correct answer is c, because it repeats the x value 4 twice in the series of coordinates.
Hope this helps!
Answer:
C.) f(x) = −4x + 200
Step-by-step explanation:
Since the number is decreasing, you know the slope will be negative, eliminating the first two choices. The equation in the last choice does not match the given data, so it can be eliminated.
In other words, the easiest way to solve this problem is to check the answers against the given data.
_____
If you want to write the equation from scratch, you need to find the slope. That is ...
(change in number of cars)/(change in weeks) = (184 -192)/(4 -2) = -8/2 = -4
This matches only one answer, but you can go on to finish the equation by starting with point-slope form:
y -192 = -4(x -2)
y = -4x +8 +192 . . . . add 192, eliminate parentheses
y = -4x + 200 . . . . matches choice C.)
