say it has 5x over 3 and then on the other side it says 3x over 7. how the heck do u do that mess? i know like if it says 8 over x and then 3 over 2 u do 8 times 2 divided by 3 but what about x's on both sides like that?

another finite math probility problem need help?

involving drawing three cards from a deck of cards. Assume that the deck contains 4 aces, 7 other face cards, and 9 non-face cards, and that you randomly draw 3 cards. A random variable Z is defined to be 3 times the number of aces plus 2 times the number of other face cards drawn.

How many different values are possible for the random variable Z?

part 1 is 9

PART 2:

Fill in the table below to complete the probability density function. Be certain to list the values of Z in ascending order

value of X probability

Can anyone actually explain to me how this mathematics question was does as I had it in an engineering test?

Can anyone actually explain to me how this mathematics question was does as I had it in an engineering test but couldn't do it:
You need to determain whether the length of copper a copper rod oven will expand by more than 2% of the original length when heated. Information you have suggests that heating to 1500 degrees C, will not result in greater expansion the the required 2%.
1)Is this information correct?
2) If not, what is the maximum temperature the rod can be heated to in order to stay within the expansion limits?
The information you have is:
The equation relating original length 'I*o' and length 'l' at temperature 't'.
l= l*o(1+at) 'a' is the coefficient of linear expansion, and 't' is the temperature.
Values given are 'I*o' = 0.250m, 'a'= 1.7× 10 to the power -5.

I would appreciate any help with this question as a question similar will come up on my JAR 66 aerospace engineering licence.

Thanks

What are the two measuring systems? One of them is Metric. What is the name of the system we use in the U.S.?

Mathamatics is the best Catagory I could think of. Most thorough, comprehensive answer gets 10 points.

What are the two measuring systems? One of them is Metric. What is the name of the system we use in the U.S.?

Can you give the name of the system and the measuring inside of it. I want both systems also, Metric and the one we use in the U.S. I forget the name of that one, so if you could tell me.

THANKS.

EG: Metric System, Centimeters, Decimeters and so on.
