Answer:
Step-by-step explanation:
So, this question involves you to play around with the numbers and the operations a bit. I've come up with a solution, but perhaps there are others as well.
So, we have:
So, what we can do is, for instance, multiply 4 and 2. Subtract that into 11. And then add the difference to 7. Thus:
This is a true number sentence. Let's do it to make sure.
First, do the operations inside the parentheses.
Multiplication comes first, so multiply:
Again, do the parentheses first. Subtract:
Now add:
So our answer is correct :)
Ok, so here:
Remember for basic probability, you have to do: Probability=Events/Possible outcomes. For multiple events, you have to multiply all together.
The probability the first guy that shows up will be 8/14, because out of the 14 people, 8 of them are men. This however isn't your answer, note the question says "Separately"
The probability the second person that comes in is a dude is 7/13, because you have the first guy already in, and only 13 left.
The third person to come in being a dude has a probability of 6/12
The fourth person to come in being a dude has a probability of 5/11
When you have multiple events, the way to solve probability is to find the chances of each as a fraction, then multiply them together.
8/14 * 7/13 * 6/12 * 5/11=1680/24024
1680/24024=168/168 (168 goes into both)
Your final answer is 10/143

Answer:
there should be 2 chipped vases
Step-by-step explanation:
Answer:
145.8 pounds
Step-by-step explanation:
So, if there is 9720 pounds total, and 98.5% of it must be pure paper, than 1 - .985 is how much can be impurities.
1-.985 = .015 or 1.5%
Now lets multiply .015 times 9720
.015(9720) = 145.8
The maximum weight of impurities is 145.8 pounds
