A community of 100 homes constructed in 2009 contains 47 that used conventional construction. The reminder used Energy Star building standards. A real estate agent is going to show a client 5 homes. What is the probability that 3 were built using conventional methods?

Right now the probability of picking blue would be 12/30. If you add another blue it would be 13/31, then 14/32, 15/33, 16/34, 17/35, 18/36. 18/36=1/2, so if he wants the probability to be 1/2 he needs to add 6 more blue.

What are winter dreams from the story "Winter Dreams" by F. Scott Fitzgerald? I don't understand what they are or what it means.

Another way to do it. 4=red 8=yellow 8=green rest=blue 4+8+8=20, 24-20=4

error
It should be 25, because 25 is the greatest number that can be divided by both of them.

I'm assuming you mean to the nearest hundredth, which would be .01

Yup, 105-79, because you have to take the highest number and lowest number and subtract them.

True, it only needs to have one side not corresponding for non-congruent triangles. It can have one, two, or all three sides not congruent.

A much easier way to do this would be: 1) x+y=1300 2) x+2z=1400 3) x+y+z=1600 Look at 1 and 2. Since x+y=1300 and x+y+z=1600, z obviously equals 300. Now substitute that back in #2. x+2(300)=1400, x+600=1400, x=800. Now substitute x and z back in #3. x+y+z=1600, 800+y+300=1600...
