If you number the pages of a book from 1 to 30 how many digits will you write?
51 Numbers
30-9 is equal to the number of two digit numbers
21*2=42
Then you add the 9 single digit ones
42+9=51
Askia Muhammad ruled what empire?
Here's a little more than you asked:
Askia Muhammad, Songhai became the largest empire in West Africa. It covered more territory than either Mali or Ghana and included one thousand different cultures. Trade was strengthened with the Mamluks in Egypt, the Merinids in the Maghrib, and the new Islamic empires in Africa. By 1591, the Songhai Empire became unmanageable due to its size. An invasion by the Moroccans virtually destroyed the empire. The Islamic legacy, however, remains in place throughout West Africa today.
Answer:Songhai
In a no correlation scatter plot if one variable is increasing what is the other variable doing?
If in fact, as you have said, there is no correlation between the variables, then
neither one cares what the other is doing, and the question has no answer.

Is temperature an example of continuous variable?
Yes.
It is a continuous variable. As used in probability theory, it is an example of a continuous random variable.
What is quantitative analysis decision making?
Quantitative Analysis provides data-driven analytical services for a range of business challenges, specializing in statistical models for site selection decisions.
In today's environment, the volume of data available for business decisions has increased dramatically. Yet too often data is not fully leveraged as a business asset because of trim analytical staffs and information overload. Quantitative Analysis can assist by applying advanced statistical analysis techniques to help you get more from your data, as well as external data sources.
With Quantitative Analysis, you'll find that even a modest investment in analysis can yield great returns in increased revenues, improved profits, and better understanding of the decision at hand. For every project we take the time to fully analyze all the appropriate data, and deliver profitable decision-making tools and knowledge
What do you do when you have three modes and they're each two numbers?
If you have 3 modes, write down the three as your answer. If the mode has two numbers, just write one of the numbers down.Repeat on the other two modes.
What is the definition of three digit number?
hundredths
* * * * *
No. It is a number in the hundreds : between 100 and 999.
Hundredths refers to numbers between 0.01 and 0.99.
What are the chances of 3 people in an office of 6 having the same birthday?
The probability that there will be 3 people born on one birthday, and 3 people born on a different birthday is 1x(1/365)2 x (364/365)3 as it doesn't matter which birthday is the one being shared. This number then needs to be multiplied by the number of possible ways the people can be arranged. For example it could be persons a, b and c sharing a birthday, or it could be persons c, e and f. The number of ways they can be arranged is 20, so multiply by 20 and we get 0.00014889. Thus there is a 0.014889% chance that an office of 6 people will have 3 who share a birthday.
What is the outlier of 43 46 49 50 52 54 78 47?
The outlier to tht would be 78 because it is higher than the other numbers!
What is the equation for wavelenght?
Several of them.
Wavelength = speed of light/Hertz
Wavelength = Planck's constant/mass of particle*Hertz
And a few more that can be manipulated to find wavelength that I will let you discover on your own.
When two line segment meet at a point an is formed and the point where is called the?
An angle is formed at the vertex
Can the variance of a sample be larger than the sample mean?
Yes,
Mean is given by, E(X) sum of samples / no. of samples.
Variance is Var.(X) = E(X^2) - [E(X)]^2.
It is the 1st term which makes the variation of variance independent of mean.
In other words, Variance gives a measure of how far the samples are spread out.
There are ten digits and twenty-six letters, assuming unconstrained choice of both. The probability of getting a repetition in the first two digits is 10/100, since there are 10 repetitious combinations of two digits among the 100 pairs of digits possible.
To calculate the probability of a repetition in the two letters, consider that there are 262 combinations, of which 26 X 25 do not contain repetitions. (There is free choice among 26 alternatives for the first letter, but only 25 choice for the following letter.) Therefore, the probability of a repetition within the two letters is (26)(25)/262 or 25/26.
The chance of a repeated digit within the four digit bloc is (10)(9)(8)(7)/104) or 504/1000.
If there is no repetition of a digit within either the two-digit bloc or the four-digit bloc, there is still a chance of repetition of a digit between the blocs. The chance of this is (8 X 7 X 6 x 5)/104 or 168/1000.
To reach the final answer, it is advantageous to calculate first the probability of not getting the specified repetition and then subtract this number from one. The probability of not getting a repetition in the first bloc is 9/10, and the probability of not getting a repetition between the first and second blocs is 168/1000. Therefore, the probability of not getting a repetition within the first bloc or between the first and the second number blocs is the product of these two, or 1512/10,000. Further multiplications by the independent probabilities of no repetition within the two remaining blocs yields a value of about 2.88 X 10-4. Therefore, the probability of at least one of the repetitions specified is about 0.999712.
