Question 4, I give thanks and 5 stars so you get more points :p Worth 15 pointsA cooler contains 5 bottles of orange juice, 6 bottles of apple juice, and 4 bottles of grape juice.

a. Janice randomly selects a bottle from the cooler. Then David randomly selects a bottle from the cooler. What is the probability that both Janice and David will select orange juice? Express your answer as a percent. Show your work.
b. Assume that both Janice and David selected orange juice. After drinking these juices, Janice and David randomly each pick another bottle from the cooler. What is the probability that neither will pick grape juice? Show your work and write your answer as a percent.

Answers

A) 5+6+4=15, so the chance that they will both get orange juice is 2/15
B) 15-2=13, so the chances that neither of them will pick grape juice is 6.5%

I think this is right, but you might want to check it if anyone else answers because I havn't done this in maths for a while.

Since gkitten wasn't sure I'll attempt this too.

a) Assuming that the bottles are not replaced from the fridge each time:
5+6+4=15
So 5/15 x 4/14 = 2/21
2/21 x 100 = 9.524%

b) So now there are only 13 bottles in the fridge:
4/13 x 3/12 = 1/13
1/13 x 100 = 7.692%

Hope I helped.

The movie theater has 250 seats 225 seats were sold for the current showing what percent of seats are empty?

Answers

The answer would be 11% because you have to do 225/250 then slide the decimal over two places.

250-225=25

25/250 * 100% = 10%

Squareroot(y-1) + 3 = y

Answers

note:xy means x times y and x(y) means the same thing

so
first we get rid of square root then
make the equation equal to zero becaues if
xy=0 then x or/and y=0

squareroot(y-1)+3=y

isolate the squareroot
subtrac 3 from boht sides

squareroot(y-1)=y-3

square both sides (since they are equal, you should be able to square both sides and still make it true)

(squareroot(y-1))^2=(y-3)^2
(y-1)=(y-3)(y-3)
y-1=y^2-6y+9
subtrac y from both sides
-1=y^2-7y+9
add 1 to both sides
0=y^2-7y+10
find what two number multiply to make 10 and add to get -7
the answer is -2 and -5

0=(y-5)(y-2)
therfore
y-5=0
and/or
y-2=0

therefor
y=5 or/and 2 might work
let's try out 2
square root(2-1)+3=2
square root(1)+3=2
1+3=2
false
so 2 doesn't work

let's try 5
squareroot(5-1)+3=5
squareroot(4)+3=5
2+3=5
5=5
true

y=5
