Answer:
5/11
explanation
Probability here is the chance of selection out of a total. So, we need to first find the total number of marbles.
total
=
5
+
3
+
2
+
1
=
11
So there are
11
marbles total. The probability that we pick one of the
3
green marbles out of the
11
is simply that ratio:
P
green
=
3
11
Same idea for yellow:
P
yellow
=
2
11
The probability of picking either of these colors is simply the sum of their probabilities.
P
green or yellow
=
P
green
+
P
yellow
=
3
11
+
2
11
=
5
11
First you have to find 5000 divided by 100 because that is the highest percent. Then you find the answer,50, and that is 1% of 5000. Next you subtract 6000 minus 5000 equals 1000. You divide 1000 by 50 and get 20. So his percent of gain is 20%
The answer is false because either way if you move the decimal three places over to make it a whole number that answer for .052 would be 52 millimeters.
There is no square root with real number for a negative number, but you can use imaginary numbers such as i which means the square root of -1
so you can factor the -1 out and get 256
you factor 256 into 2*2*2*2*2*2*2*2 or 2^8
so if you group them into (2^2)(2^2)(2^2)(2^2) then square root all of them you get 2^4 or 16
but there is the immaginary part so the answer is 16i
