Answer:

Skewed to the left.

Step-by-step explanation:

The left side of the graph is at 2 and is 4 units from the middle at 6. The right side of the graph is at 9 and is 3 units from the middle. As such the graph is skewed left since it is a greater distance from the left to the center.

20 is what percent of 50?

djverab [1.8K]

We can rephrase the question as "What percent of 50 is 20?".
"What percent ..." is an unknown. We'll use the variable x to represent this unknown.

The word 'of' in mathematics can mean 'multiply'. Likewise the word 'is' can mean 'equal'.

Now we have the phrase "20 equals to x times 50".

Or in an equation: 20 = x * 50

Solve for x.

20 = x * 50
$\frac{20}{50}$ = x <-- Divide both sides by 50

Simplify the fraction.

$\frac{20}{50} = \frac{2}{5}$

Convert the fraction into a decimal.

$\frac{2}{5}$ = 0.4

Convert the decimal into a percent.

0.4 = 40%

So, 40% is the answer.

In numeric storage, a cross-reference is filed in the a. alphabetic index. b. accession log. c. numbered file. d. Both a and b

Lera25 [3.4K]

Answer:

A- Alphabetic index

Step-by-step explanation:

An alphabetic index is a reference to a numeric file. It is alphabetically organized to allow easy location when the assigned number is not known.

An alphabetic index is important in numeric storage because, with it, rapid retrieval of a record is possible. The index uses names and subjects to code for a numeric record. These subjects serve as codes for either each file or a group of files, sorting the information base in an organized format. Names or just single letters could be used in the index as the code for the numeric record strorage.

When trying to locate a file, the alphabetic code used for the numeric information or the group of files, is the first source assessed. The alphabetic index of records is best kept in a single location to avoid a search in multiple locations, complicating the retrieval of a record.The index should be kept valid by ensuring it is up-to-date and is accurate.
