When a number is divided by 100 the digits move?

The digits should stay where they are. The decimal point

should move 2 places to the left.

What is the relationship between decision variables and the objective function?

In optimization models, the formula for the objective function cell directly references decision variables cells. In complicated cases there may be intermediate calculations, and the logical relation between objective function and decision variables be indirect.

What does relative error percentage mean?

Relative error percentage is a decimal percentage between 1 and 0 such that if you multiply the actual answer by (1-errorrel) you get your approximate value. In other words relative error is an indicator of how far away your apporximation is from the real value in terms of percent of the real value.

What do you do if you reject your hypothesis?

If a hypothesis is rejected because it was disproved, then one can rephrase the hypothesis to exclude the disproven data. For example: Hypothesis: White appears black. Data: When viewed by the naked eye in daylight, white appears differently than black. When viewed by the naked eye in darkness, white appears black. Reword hypothesis: In darkness, white appears black.

What information do you need to calculate a probability with a normal distribution?

Only the mean, because a normal distribution has a standard deviation equal to the square root of the mean.

What is the median of a single value?

The median is the number in the middle. You find the median,

by putting the values in order from lowest to highest, then find

the number that is exactly in the middle.

If you only have a single value, one could argue that it is in the middle.

That would make the single value the median. One could also argue that there

no numbers on either side to the definition makes no sense and there is no median

of a single value.

What is substantive significance?

A 'Substantive Significance' is concerned with the meaning. So, if you do an experiment concerning the population in a country, what do the findings say about population effects themselves?

Hope this helps!

What does the sky word means in Navajo?

When you make a measurement which digit in the measurement is the estimated digit?

It depends on what kind of measurement you are making, but it would generally be the digit farthest to the right.

For example, if you have good eyes and a good ruler, and you are measuring something in millimeters, you can estimate tenths of a millimeter. Suppose the length of a rectangle is between 74 and 75 mm. Look closely between the millimeter marks on the ruler. Suppose the end of the rectangle is about a third of the way from the 74 to the 75, then you good estimate that the length is 74.3 mm. The digit you estimated is the last one, the 3.

What is link time error?

A link time error occurs during the linking phase of program compilation, when the linker encounters issues resolving references between different object files or libraries. This can happen due to missing symbols, incompatible types, or unresolved external references. Such errors prevent the creation of an executable file, requiring developers to fix the underlying issues in the code or project configuration. Essentially, link time errors indicate problems that arise after individual code files have been compiled but before they are combined into a final executable.

How do you make a cumalative frequency?

Hi im 15 n i am doing my maths coursework which requires me to make a few cumulative frequency curves. Basically all you do is add the frequency as you go along. for example if the frequencies were:

4

5

2

3

then the cumulative frequency would be

4

9

11

14

You would then use this by plotting it along the y axis. There is a little more but that's mainly what u need to know to get started.
