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.

What is a proportion?

Noun:

  1. A part considered in relation to the whole.
  2. A relationship between things or parts of things with respect to comparative magnitude, quantity, or degree: the proper proportion between oil and vinegar in the dressing.
  3. A relationship between quantities such that if one varies then another varies in a manner dependent on the first: "We do not always find visible happiness in proportion to visible virtue"(Samuel Johnson).
  4. Agreeable or harmonious relation of parts within a whole; balance or symmetry.
  5. Dimensions; size. Often used in the plural.
  6. Mathematics A statement of equality between two ratios. Four quantities, a, b, c, d, are said to be in proportion if a/b = c/d.
AnswerA porportion is a size of something. For example, smaller or bigger porportions of a meal. Or blowing a situation out of porportion.

What is the probability of getting one prime number when rolling two dice?

In solving problems like this, the most straightforward approach is to make a table. Columns are used to show the six outcomes from one of the dice, rows the outcomes from the other die. In each cell of the table put the sum of the two dice. Now go throught the table row by row, counting the values that are prime numbers. There are 36 cells in the table, and I counted 15 primes, making a probability of 15/36 = 5/9.

But my counting has been wrong before! You had better check it.

What is the smallest 3 digit number in 1 000?

For the purposes of school work, the answer they are probably looking for is 100.

What is a Standard error?

The standard error (SE) is a statistical measure that quantifies the variability or precision of a sample mean in relation to the true population mean. It is calculated as the standard deviation of the sample divided by the square root of the sample size. A smaller standard error indicates more reliable estimates of the population mean, while a larger SE suggests greater variability and less confidence in the estimate. SE is often used in inferential statistics to construct confidence intervals and conduct hypothesis tests.

Compare and contrast distribution by force and distribution by equal sharing.?

Distribution by force involves allocating resources or goods through coercive means, where power dynamics dictate who receives what, often leading to inequality and conflict. In contrast, distribution by equal sharing emphasizes fairness and equity, where resources are divided equally among individuals, fostering cooperation and social harmony. While force-driven distribution can result in immediate control, it often breeds resentment, whereas equal sharing promotes collective well-being but may not always address differing needs or contributions. Ultimately, the choice between the two reflects differing values regarding power, fairness, and social justice.
