Answer:
(4)/(\sqrt(2))
Step-by-step explanation:
The solution to your problem about the probability <span>of getting first a red and then a black marble is as follows:
</span><span>(3 red / 8 total) * (2 black / 7 total) = 3/28
</span>
Therefore, the probability of getting first a red and then a black marble is 3/28.

Third, the graph decreases from left to right because if you plug it into a graphing calculator - you can see that the line is a straight line, and does not decrease or increase whatsoever
Answer:
v=5.42m/s
Step-by-Step Explanation:
We can use conservation of energy to solve this
mgh=1/2mv^2
2gh=v^2
v=sqrt(2gh)
v=sqrt[2*9.8m/s^2*(6.5-5)]
v=5.42m/s
Answer:
Step-by-step explanation:
Probability (P) is calculated as
P = 
The first required outcome is a red sweet from a total of 3 + 5 = 8
P( red) = 
There are now 2 red left and a count of 7, since 1 has been eaten, thus
P( second red ) = 
P( red and red ) = × = 
=
