What two numbers can you multiply and get 216 and then add the same numbers and get 15?

Let's denote the two numbers as x and y. We have the equations xy = 216 and x + y = 15. By solving these equations simultaneously, we can find that the numbers are 9 and 24. This is because 9 multiplied by 24 equals 216, and 9 plus 24 equals 15.

How many 4 digit combinations can be made with 4 digits?

9,000 - all the numbers between 1,000 and 9,999 inclusive.

* * * * *

NO. Those are PERMUTATIONS, not COMBINATIONS. Also, the question specified 4 digit combinations using 4 digits. The above answer uses 10 digits.

If you start with 4 digits, you can make only 1 combination.

What is the units digit of 8 to the power of 50?

8 to the first power ends with 8.
8 to the second power ends with 4 (8x8 = 64).
8 to the third power ends with 2 (8x4 = 32).
8 to the fourth power ends with 6 (8x2 = 16).
9 to the fifth power ends with 8 (8x6 = 48).

After this, the cycle repeats.

How are the numbers on a dice arranged?

A normal die has the numbers 1,2,3,4,5 and 6 on its faces. The numbers are arranged so that those on opposite faces of the die sum to seven. This then means that the number 1,2 and 3 share a vertex. When viewed from above the vertex, these three numbers usually go in a counterclockwise direction. This is a right-handed die. Left-handed dice, where the three numbers are in a clockwise configuration, also exist.

What does APEC mean?

Oh, dude, APEC stands for Asia-Pacific Economic Cooperation. It's like this big group of countries in the Asia-Pacific region that come together to talk about economic stuff. So, yeah, it's basically a fancy way of saying they're all getting together to chat about money and trade and all that jazz.

How do you say 100000000000000000?

Oh, dude, that's a big number! So, like, you'd say 100,000,000,000,000,000 as "one hundred quadrillion." Yeah, it's a mouthful, but hey, numbers gotta number, right?

What is an example of weak positive correlation?

An example of weak positive correlation would be the relationship between the amount of time spent studying for a test and the grade achieved. While there may be a slight increase in grades as study time increases, the correlation is not very strong. This means that studying more does not guarantee a significantly higher grade, but there is still a positive trend between the two variables.

How many 4 digit combinations of 1-4?

There are 24 combinations using each digit once per combination: 1234 1243 1324 1342 1423 1432 2134 2143 2314 2341 2413 2431 3124 3142 3214 3241 3412 3421 4123 4132 4213 4231 4312 and 4321.

What are all the possible 4 digit codes using the numbers 123?

Since you've only given us 3 digits to put in 4 places, we have to assume

that it's OK to use the same digit more than once in a code. So we're also

going to assume that there's no limit on repetition.

The first digit can be any one of 3. For each one . . .

The second digit can be any one of 3. For each one . . .

The third digit can be any one of 3. For each one . . .

The fourth digit can be any one of 3.

Total possibilities = 3 x 3 x 3 x 3 = 81 possible codes.

Which are:

1111, 1112, 1113, 1121, 1122, 1123, 1131, 1132, 1133, 1211, 1212, 1213, 1221, 1222, 1223, 1231, 1232, 1233, 1311, 1312, 1313, 1321, 1322, 1323, 1331, 1332, 1333, 2111, 2112, 2113, 2121, 2122, 2123, 2131, 2132, 2133, 2211, 2212, 2213, 2221, 2222, 2223, 2231, 2232, 2233, 2311, 2312, 2313, 2321, 2322, 2323, 2331, 2332, 2333, 3111, 3112, 3113, 3121, 3122, 3123, 3131, 3132, 3133, 3211, 3212, 3213, 3221, 3222, 3223, 3231, 3232, 3233, 3311, 3312, 3313, 3321, 3322, 3323, 3331, 3332, 3333

What is non example of a dependent variable?

That means finding something that changes, but isn't dependent on something else changing it. I would say that time is a non-example. It keeps changing regardless of how other things are changing. (Now, there is an exception to this in physics, where the passage of time changes in relation to velocity, but we're assuming that we are just talking about time as it is typically for us.) Another example would be something like a quantity purchased. Let's say that candy bars cost $ .75 each. The total cost would be dependent on how many candy bars are purchased, so the total cost would be the dependent variable. The number of candy bars purchased would be the independent variable, since it doesn't depend (within reason) on the total price. Since it is an independent variable, it is not a dependent variable, so it is a non-example of a dependent variable. For example, someone could purchase either 3 or 4 candy bars, and the total price depends on how many are bought, but how many are bought doesn't depend on the total price.

What is the percentile if a z- score is 0.62?

To determine the percentile of a z-score, you would look up the z-score in a standard normal distribution table. A z-score of 0.62 corresponds to a percentile of approximately 73.8%. This means that 73.8% of the data in a standard normal distribution falls below a z-score of 0.62.

What is the front end estimation to subtract 189 from 643?

Front End Estimation can be confusing before you understand it. There are two simple steps for front end estimation: add the digits of the two highest place values, insert zeros for the other place values. Now let's put that into us for your question!

189-643 =

(1 & 8 are the first two digits for 189 ... 6 & 4 are the first two digits for 643)

18_ - 64_ =

(Fill in zeros for the place values you have emptied)

180-640= -460

-460

What is 1 trillion years called?

I will assume you mean the trillion in the "short scale", i.e., a 1 followed by 12 zeroes. This MIGHT be called a terayear, abbreviated Ta ("a" for "annum"). However, it is much more common to write this as "a trillion years", or, using scientific notation, as 1012 years. Note that a trilion years is about 70 times the estimated age of the Universe.

What is a 1000 digit number called?

A 1000-digit number is called a "millidigit" number. The prefix "milli-" denotes one thousandth, so a millidigit number is a number consisting of 1000 digits. In the realm of mathematics, such large numbers are often encountered in fields like cryptography, number theory, and computer science.

What does 'Hosanna in Excelsis' Mean?

It actually it is from a Hebrew word that literally means, "save now, we pray." It could also mean a cry to the Lord. People sang this before the Crucifixion of Jesus in Calvary. Listen to this song: Hosanna by Hilsong United. It can further explain :).

"Keep the Faith"

In Latin, it would mean 'Hosanna in the Highest'.

In my country in Spanish it would be "Osana en el Cielo", or if you translate this in English it would be "The Holy one is in the Heavens" or "All of God that is in Heaven". There are many different ways to interpret it.

How often are there two Friday the 13th's in a row?

Once every 6 or 11 years, in a regular cycle through the year 2100, when the cycle will change. Only one pairing, a non-leap year where February 13 is on a Friday, will have the 13th of the next month (March 13) also on a Friday.

The recent years where this occurs demonstrates the cycle:

1953

1959 (6 years)

1970 (11 years)

1981 (11 years)

1987 (6 years)

1998 (11 years)

2009 (11 years)

2015 (6 years)

2026 (11 years)

2037 (11 years)

2043 (6 years)

What is the largest number that rounds to 460 to the nearest ten?

The largest number that rounds to 460 to the nearest ten is 465. When rounding to the nearest ten, we look at the digit in the ones place. If it is 5 or greater, we round up; if it is less than 5, we round down. In this case, 465 rounds up to 470, making it the largest number that rounds to 460.

What is the formula for PF2?

The formula for the compound containing one phosphorus atom and two fluorine atoms, PF2, is PF2. In this compound, phosphorus has a charge of +3 and each fluorine atom has a charge of -1. Therefore, the chemical formula is written as PF2 to indicate the ratio of atoms in the compound.

How many 6-number combinations are there for numbers 1-39?

To calculate the number of 6-number combinations from a pool of numbers 1-39, we can use the combination formula, which is nCr = n! / (r!(n-r)!). In this case, n = 39 (total numbers) and r = 6 (numbers chosen). Plugging these values into the formula, we get 39C6 = 39! / (6!(39-6)!) = 3,262,623 unique combinations.

What is the difference between the opening verses of the two Gospels?

The opening verses of the two Gospels, Matthew and Luke, differ in their focus and audience. Matthew's Gospel begins with a genealogy tracing Jesus' lineage back to Abraham, emphasizing Jesus' Jewish heritage and connection to the promises made to the Jewish people. On the other hand, Luke's Gospel starts with a prologue addressed to a broader audience, highlighting the historical context and the orderly account of Jesus' life that Luke intends to provide. These differences reflect the unique perspectives and intended audiences of the respective Gospel writers.

List the 4 digit combinations made using 1 through 9?

Oh, isn't that just lovely? You can create so many beautiful combinations using the numbers 1 through 9. Just think of all the possibilities waiting to be discovered! Keep exploring and let your imagination run wild with all the different combinations you can come up with.

Statistics are like clay of which you can make a good or devil as you please explain?

It means that you can take a load of statistics and make all sorts of conclusions you want for it to back up what you want to find. You can ignore certain things, while present other things that support what you want to say. An example is where 52% of children from the south of the city have passed an exam, while 54.3% of the children in the north have passed an exam. So a politician may say that children in the north are more intelligent. In actual fact, the sample size may only be around 17, while the test is only aimed at a small age group, so the politician is wrong to make such a sweeping statement. It's a case of interpreting the statistics how you like, it can be easily done, but may be wrong to do so.

What is a number followed by 23 zeros called?

A number followed by 23 zeros is called a "septillion" in the short scale naming system used in the US and modern British English. In the long scale system used in some European countries, it is called a "trilliard." This number is represented by 1 followed by 24 zeros in standard numerical notation.
