Answer:

\Huge \boxed{2x-3=-21}

Step-by-step explanation:

Let the number be x.

The difference of two values is the result from subtracting them.

2x-3=-21

Add 3 to both sides.

2x=-18

Divide both sides by 2.

x=-9

The number is -9.

  • The distribution is skewed left.
  • The median is an accurate measure of center.
  • The interquartile range is an accurate measure of spread.

<h3>How to find the Distribution of data?</h3>

Probability plots might be the best way to determine whether your data follow a particular distribution. If your data follow the straight line on the graph, the distribution fits your data. This process is simple to do visually. Informally, this process is called the “fat pencil” test.

For skewed distributions, it is quite common to have one tail of the distribution considerably longer or drawn out relative to the other tail.

As, it is known that, when the distribution of data is left-skewed, the mean is less than median.

  • In any research of distribution, the distribution is described by its shape. If there are more higher values than lower values, the distribution is skewed left.

  • The distribution can be described by its center. If the distribution is skewed left or right, the median is an accurate measure of center.

  • The distribution can be described by its spread. If the data set does not have an outlier, the interquartile range is an accurate measure of spread.

any whole number containing 3 or more digits can be ÷ by 4 if the last two digits form a number that is divisible by 4 why?​
NARA [144]

Answer:

100 is always divisible by 4. Therefore it doesn't matter which number is up front.

the two other digits are important because there are 2-digit-numbers that are not divisible by four. "14" is not divisible by four, but "24" is.

34 isn't divisible, 44 is, 54 isn't.

So both digits will need to form a number that is divisible by 4, or it will not work.
