A density curve looks ike an inverted letter "v". The first segment goes point (0,.06) to the point (.05,1.4). The second segment goes from (.5,1.4) to (1,.6)
1. Verify that the area under the curve is 1, so that is a valid density curve.
2. Determine the median. Approximate the locations of Q1 and Q3.
3. What percent of the observations lie below .3?
4. What percent of the observations lie between .3 and .7?

I conducted an investigatory project concerning the growth of pechay (Wild Cabbage) and mung bean. I planted them on three different soil types (loam, clay, and sand). Some grew but some didn't. How do I know that they didn't grow because the soil does not support it and not just because it was dead/dormant in the first place?

I know that winds go counterclockwise in the Northern hemisphere and clockwise in the Southern hemisphere due to the Coriolis Effect but why does the Coriolis Effect go in different directions?

When you have a certain number of digits, and these digits start and end somewhere, how do you know the maximum number of variations these digits can form?

For example, suppose I own a company and I was given a fixed IP address (the two parts to the left are fixed) and open (the two right parts are open). Suppose the left parts are 111.111 and the rest is open, for instance: my machine would be 111.111.001.001, my secretary would be 111.111.001.002, and so on. The two parts to the right start with 0 and end with 9. How can I know the maximum number of computers my company can have based on that very address?

Another way to phrase this question is this: suppose I have a safe and it has three digits that you have to get right for it to open. Suppose the permitted digits are 0-9 and A-F. It can be 001, 0F5, F79, and so on. How can I know how many variations this formula can form? I'm sure it would be a huge number, and that's what I want to know: how can I calculate that number?

Thanks

If you say in december, the southern hemisphere will be facing the sun that means it will cause summer. So northern hemisphere will cause winter. But the earth itself is also rotating around it's own axis that means there will be sometimes when the northern hemisphere is facing the sun. So why december in northern hemisphere (countries there) is winter for that month?

There are always lots of warnings on electronics when large capacitors are used (televisions, car audio etc). I have worked with capacitors a little bit and have seen that they can in fact deliver a large shock. However, whenever a capacitor is used, it is only capable of charging up to the voltage of it's power source (12V car battery, voltage from power supply in TV), correct? If so, what makes the capacitor so dangerous to work with?
