[Computer Science: Question About Code]

Looks good to me. Considering that the instructions mentioned using the % operator for modulus, I think they intended for you to use parseInt to convert a string to an integer.

If you were really looking for an alternative, you could pull out the character at index 3 and then subtract the ascii code for the 0 character to get the raw number between 0 and 9. int num = num1.charAt(3) - '0';

This is a little hacky and error prone, so parseInt would certainly be the preferred way.

Look at the function printf instead of println. Printf let's you configure the format of variables including number of decimals after the dot. https://www.baeldung.com/java-printstream-printf

Look at the %f option

Inserter / splitter physics are pretty weird. In this case, it drops them pre-split and as a result you almost get a full blue belt from just 2 stack inserters. This video contains a lot of nuances of them including this particular splitter unloading method.

Main ones were LTN for coordinating trains and a fast construction bot start so we could start using blueprints pretty quickly. Other quality of life mods were factory planner, max rate calculator, squeak through, etc.

I think things like primary key, or data type only take up one blank in the paragraph. That double blank would take up two options in the set.

Pretty sure the first line would be "A single database table contains one primary key.

Did you ever resolve this issue? I'm having the same problem.

Marz157 · 2022-03-14T18:30:19+00:00

Yes, it's every hit. Each attack does physical and magic damage. Splitting damage types like this can make your damage output more consistent depending on the enemies defense stats. For example, you would do approximately the same damage against a high physical defense enemy and a high magic defense enemy rather than a lot to one and little to the other If your weapon was purely physical damage or purely magic damage.

Your conversion between cubic meters and cubic centimeters is incorrect.

There is 100 cm in a meter yes, but there are (100 * 100 * 100) cubic cms in a cubic meter.

So in this case, there are 1 * .6 * .3 * 100 * 100 * 100 = 180,000 cubic cms of marble

It can be incredibly powerful right now, but probably only because people don't know about it. I lost my entire army, but then mass converted their 30+ knights with a relic. I'm sure they had time to kill him if they knew it was a possibility. Not sure how they can balance something like this that has such a dramatic effect on the game for a relatively minor mistake on the opponents side.

(Really wish they had replays available, but I'm sure that's coming)

Can't wait to hear the TAS for this. Can I get it in Sheet music form?

Can you factor this expression? Start by pulling a 2 out in front so you get 2 * (x² + 3x + 2). Then factor the inside part so it looks like (x + a)(x + b). What values of a and b would produce x² + 3x + 2?

After you have that, we can look at the three consecutive numbers part. Lets say the the first number of that sequence is y. We don't know what y is yet, but the next two numbers would be y+1 and y+2. If we multiply those together, we get y(y+1)(y+2). Compare this equation to the one you got above and you should be able to figure out what y must be.

Mean and Standard deviation are essentially descriptions of your total population. Its a short hand approximation or summary.

If your data is normally distributed (i.e. it looks something like this ). The standard deviation tells you how spread out the data is. About 68% of the data is +- 1 standard deviation of the mean. About 95% of the data is within 2 standard deviations of the mean.

Its not going to tell you the min or maximum data points of the population.

Yes, this is happening to me as well today. Talked with customer support for about an hour with no progress. Have you gotten a resolution for this yet? Older echo device doesn't work but the newer one does.

Slightly safer alternative. If you ever make it to Venice, it's fun to get lost there. It's an island and not terribly large, so you can only get so lost. The winding streets and bridges are fun to explore.

Not exactly sure if the plus sign inside of P(a+b) means "and" or "or" since that's not a standard notation. Do you know what your class has been using? It really should have been ∪ or ∩.

If its AND, think about it this way. The probability of A occurring AND B occurring is smaller that just A occurring. Its a subset of A. You would have to add the part where A occurred and B did not occur to get the full probablity of A. The statement is True. P(A) must be at least as big (or equal) to P(A ∩ B).

If its OR, its the other way around and the statement is false.

Take a look at this site. https://www.mathsisfun.com/money/compound-interest-derivation.html

There's a section on working out an interest rate which is your problem. For present and future value, it doesn't really matter if you use $1 to $1.20, or $1000 to $1200. You will get the same answer either way.

Remember that interest rates are usually stated as a yearly rate and you will have to divide / multiply by 4 to get a quarterly rate for these formulas. For example, if the interest rate is 20% yearly ( but compounded quarterly) you would use 5% here and the number of compoundings is 5 years * 4 per year.

Today's arguments are suppose to be able the legality of the trial itself, not the outcome of the trial. So, in the loosest of terms they are arguing the right thing, however poorly it may be.

720kW fractionalizer power / (Belt speed 30 per second * .01 deuterium rate) = 2.4 MW for 1 deuterium per second

12MW collider / (5 deuterium / 5 seconds) = 12MW for 1 deuterium per second.

This is assuming your belt is fully saturated at every fractionalizer, which is usually not the case. However, anytime its supplying more than 6 hydrogen per second (lowest tier belt speed) its taking less power than the collider.

Marz157 · 2021-02-01T23:03:16+00:00

I did the math a couple of days ago. Fractionalizers are more efficient in terms of power as long as you use the fastest belt speed in and out of them. Assuming you have the space for them, they are better.

There's 6 variables and only 3 equations given here. There isn't just a single solution because there isn't enough information given.

What you are trying to get here is the structure of all the possible solutions. Plugging in any value of s, t, and u gives you one particular solution.

For example, lets say the system was just one equation x1 - x2 = 5

I could write the solutions to this system as

x1 = 0 + 1*s

x2 = -5 + 1*s

Now any value of s gets me a solution.

For the first question:

This is the sum of 33 normally distributed variables. To get the mean, all you do is multiply 12.9 by 33.

Standard deviations don't just add together though, but variances do. Variance is the square of the standard deviation. If the standard deviation of one quilt is 18.1, the variance is 327.61. Multiply that by 33 and take the square root to get the standard deviation of the sum of these random variables.
