By what is P i assume you mean what is the probability.
Well probability is always the specific group divided by the total
To find the total add all the marbles together
4 + 6 + 14 + 5 +8 = 37
Before we move on notice the question says that the marble is replaced after being chosen meaning the total stays the same for every pick
Red Marbles Probability:
red marbles/ total
6/37 or if you divide it out 0.162
Blue Marbles Probability:
blue marbles/total
8/37 or 0.216
Answer:
x² -4x +4
Step-by-step explanation:
(x-2)(x-2)
x²-2x -2x +4
x² -4x +4
First you have to have the absolute value isolated so the 2 has to be divided. Then set up the two cases and solve.
Answer:
y= 3x^2 y= 3^x

Answer:
x=1
Step-by-step explanation:
- choose a side to get rid of so since its easier to take 6 away from seven we will do that but remember what you do to one side you have to do to the other
- so take away 6x from the left that leaves 0 your equation should look like this 4=-3+7x remember that we have to to it to the right side too
- so take 6x away from the 7x on the right side and that leaves 1x so it should look like this 4=-3+1x
- then since it's a -3 you will need to add 3 for it ton equal 0 so it will look like this 4=7x
- but dont for get to do the same to the other side so add 3 to the 4 on the left so it will look like this 7=7x
- then divide by 7 to get x by itself so it will look like this 7=x
- but you aren't done yet you still have to divide the left by 7 so it will look like this 1=x
and thats all there is to it hope this helps
