What does 1012000 mean?

If this represents a number written in the common base of 10, then "1012000" means "one million 12 thousand". If it represents a number written in the base of 3, then "1012000" means "eight hundred sixty-four". It it represents a number written in the base of 8, then "1012000" means "two hundred sixty-seven thousand two hundred sixty-four". It could represent a number written in any base, except 2 (binary).

Who developed Pascal's triangle?

Some of the concepts were known before him, but Blaise Pascal was the one credited with constructing it.

Wap to represent a pascal triangle?

it's easy

i am assuming you know programming as you are asking a question of a high standard.

The formula for any number in the traingle is (r-1)!/[(c-1)!*(r-c)!] where r represents row number and c represents column number.

Note:- '!' sign means factorial. Eg:- 5! = 5 x 4 x 3 x 2 x1.

Median of a data is 20 If each is obesrvation in the data is increased by 2 then what is the new median. Need descriptive answer?

The median of a set of values or data is the value which lies half-way along the series when it is arranged in ascending or descending order. If there are an even number of data entries then the median is the mean of the middle two values.

1) If there are an odd number of values then there will be the same number of values higher than the median as there are below the median. An increase of 2 to each member of the set does not affect the order and the existing median remains the middle placed value So, 20 becomes 22.

2) Where there are an even number of values then both middle values will increase by 2 (a total increase of 4). The median is the mean of these two values and therefore increases by 2 (as the increase of 4 ÷ 2 = 2). So, 20 becomes 22.

What is the units digit in 899?

899 means 8 x 100s + 9 x 10s and 9 x units. So the 9 on the right hand side is the units.

How many digits 1 through1000?

2893 digits in all, made up as follows:

9 1-digit numbers (1 to 9) = 1*9 = 9 digits

90 2-digit numbers (10 to 99) = 2*90 = 180 digits

900 3-digit numbers (100 to 999) = 3*900 = 270 digit

1 4-digit number (1000) = 4*1 = 4 digits

Pablo rolled a standard die times He got a 1 twelve times How does this result compare to the expected results?

The expected values were 2 of each value.

This differs significantly from what was expected.

You could show that the die is most likely not fair by using a chi squared test for goodness of fit.

How do you know if a set of numbers is an equation?

An equation contains mathematical symbols, such as + - / *. However, there are also other kinds of mathematical symbols (algebra, trigonometry and calculus) which may look different and some of which are words. examples of this may be:

cos(x) tan(x) sin(x)

to name a few.

There are however, more often than not, "standard" (+ - / *) operators in the more advanced mathematical equations to.

What if one mode is said 2 times and the other mode is said 3 times what is the mode in math?

Not sure what you are asking, but if there are two modes it is called bimodal and if there are three, it is trimodal.

If one number occurs 2x and one 3x, the one that occurs 3x is the mode.
