What is the origin of the expression plus one?

The expression "plus one" simply means to add 1 to whatever it is applied to.

If you are referring to the "+1" sometimes found in comments on forum posts and the like, it is a reference to buttons labelled with "+1" or similar text, used to vote for the post or indicate a positive opinion of the post.

Addendum:

It's also possible that this question refers to the phrase as used on invitations - where the invitation is for the recipient and their guest. It can be used when you wish to invite someone to a function and aren't sure of who they're currently seeing...

What is the token method?

Tokenizing is the process of taking big pieces of source data, breaking them into little pieces, and storing the little pieces in variables. Probably the most common tokenizing situation is reading a delimited file in order to get the contents of the file moved into useful places like objects, arrays or collections. We'll look at two classes in the API that provide tokenizing capabilities: String (using the split() method) and Scanner, which has many methods that are useful for tokenizing.

How do you calculate percentage error?

It is your estimate minus the true value divided by the true value and multiplied by 100.

So, % error = (estimate - actual) / actual * 100, in absolute value.

For example, if you estimate that there are 90 jelly beans in a jar when there are actually 130 your percentage error is:

(90-130)/130 * 100 = -40/130 * 100 = -0.308*100 = -30.8%

After absolute value, the answer is simply 30.769, or 30.8%.

What does Mean Median Mode and Range mean in math terms?

In math, median is used to refer to the middle number in a group. To determine the median, you order the numbers from (lowest) to (highest) and find the middle number in the series. If there are two middle numbers, then add them together and divide by two to find the mean. For example, suppose you were given the following set of numbers, which for example were scores on an exam, and asked to give the mean grade:

74, 83, 65, 88, 85, 79, 91, 53, 76, 82, 44, 73

Now you rearrange them from least to greatest:

44, 53, 65, 73, 74, 76, 80, 82, 83, 85, 88, 91

Finding the middle numbers in the series, they are 76, and 80. Now add them together (76 + 80 = 156) and divide by 2 (156 / 2 = 78). So the mean for this set of numbers is 78.

The mode is the number in a series that occurs most frequently (most common. Simply find the number that appears the greatest number of times in the group. For example, the mode for the following set of numbers is 21.

34, 21, 7, 56, 21, 7, 98, 45, 21

It occurs 3 times. However, suppose there were another 7 in the series, there would be two modes: 21, and 7.

Mean is the average of a series. To determine it you add up all the number in the series, and then divide by the number of numbers in the series. Let's use the exam scores as an example:

74, 83, 65, 88, 85, 79, 91, 53, 76, 82, 44, 73

Add them all up, that makes 893. Now to find the mean, we divide by the number of numbers in the series, which is 12. The mean in this example is (893 / 12) 74.4, so that was the average score for the graph. It is more accurate than the median.

Range is how high and low a series spans. To determine it, you simply identify the lowest and highest numbers in the series, and subtract the lowest from highest. That is the range in a group of numbers. So, using the same set of number as an example:

74, 83, 65, 88, 85, 79, 91, 53, 76, 82, 44, 73

The lowest is 44, and the highest is 91. The range is (91 - 44) 47

mean: all the numbers added up and divided by the number of numbers

E.g

2,5,6,7

(2+5+6+7) divided by 4= 5

The mean is 5

Median is the middle number

e.g

1,2,3,4,5,

The middle number is 3

Median = 3

Mode: the mode is the most common number

E.g.

2,2,2,2,3,3,3,4,4,5

There are four 2's, three 3's, two 4's, and one 5

Mode = 2

Range is the highest number and lowest number subtracted from each other

e.g.

3,5,7,8,9

9-3=6

Range =6

What is slack simulation?

Slack means different things, depending on context. For this question, I assume that slack is the time that somebody is waiting for somebody else to do something.

Slack simulation, then, is a simulation where you evaluate different efficiencies and/or worker/consumer ratios, in an attempt to minimize or optimize slack, i.e. wasted, time.

What does median means in math?

The term median refers to an average value indicated by the middle number or numbers in a series. It can be different from the "mean", which is the average value found by adding the numbers and dividing.

Where there is an odd number of values, the median is the central (middle) value.

For example, in the set [ 1, 2, 7, 50, 100 ] the median value is 7. There will be as many values less than the median as there are greater than the median. (if you have duplicate values, more than one may be equal to the median)

Where there is an even number of values, the median is the mean (average) of the two central values. For example, in the set [ 1, 2, 7, 9, 50, 100 ], there are two central values, 7 and 9. The median would be 8, and again there will be as many values less than the median as there are greater than the median.

To find the median : put your numbers in order by their value, and count the number of values. Divide the number of values by two to locate the center value or values. Where the number of values is even, add and average the two in the middle.

Example : values [ 27, 18, 3, 99, 55, 1, 16 ]

Ordered set : [ 1, 3, 16, 18, 27, 55, 99 ]

Median : 18

What is numeric value and example?

Numerical value = absolute value = a number's distance from zero on the number line.

For example, |3| = 3, and | -3| = 3. So we can say that -3 and 3 are 3 units from zero.

velocity is the distance divided by the time it takes to go that distance.

let velocity equal V

let distance equal D

let time equal T

v = d/t

velocity has units of length per rate

distance has units of length

time has units of rate

the length can have units such as

1) meters, centimeters, millimeters, kilometers

2) feet, inches

3) yards

the time can have units such as

1) seconds, minutes, hours, years

it depends on which system you are using for you units then you will know which units to choose from. the most common is meters per second (m/s)
