Answer: Probability = 44%
Step-by-step explanation:
To find the probability of finding 2 black balls in a row, we first need to find the probability of finding 1 black ball at a time.
To do that, we need to divide the amount of total black balls by the number of total balls.
Black balls = 6
Total balls = 3 + 6 = 9
6 divided by 9 = 0.(6)
If you multiply 0,(6) by 100%, it will give you 66% (rounded) of getting a black ball.
Now, to find the chances of getting 2 black balls in a row, we need to multiply
by
. What we are doing is squaring the chances of getting one black ball, by the number of times we want to get it.
That is equal to 0,(4)
Multiply 0,(4) by 100%, and it will give you 44%(rounded) chances to get a black ball 2 times in a row.
Probability = 44%

Yes, it is possible. For example, let's say that point A is (0,4) and there's a reflection over the y-axis, then point A would still be (0,4).

If a total of 780 joules of energy is lost by 25.0 grams of this substance, the heat of fusion is 31.2 J/g
The energy lost, H = 780 Joules
Mass of the substance, m = 25.0 grams
The Energy lost is the product of mass and the heat of fusion
The heat of fusion, c, is calculated using the equation below:
H = mc
Substitute H = 780 Joules and m = 25.0 grams into the equation
H = mc
780 = 25c
Divide both sides by 25

The heat of fusion of the substance is 31.2 J/g
