Answer:

SELECT column_1, column_2, ... column_n

FROM table_name_1

JOIN table_name_2 ON table_name_1.primaryColumn = table_name_2.foreignKeyColumn

AND table_name_3 ON table_name_1.primaryColumn = table_name_3.foreignKeyColumn

Explanation:

The SQL or structured query language statement returns information from the three tables in the database with the 'select' and 'join' clause in the statement. There are several types of join but the default is the inner join. Other types of join are; outer, left and right join.

What would be the results of the following code? final int SIZE = 25; int[] array1 = new int[SIZE]; … // Code that will put valu

xz_007 [3.2K]

The code is first declaring array1 as a new array of integers with length 25. Then the comment tells us that somewhere in the middle of the code, values are given to each element of array1.

Lastly, we are iterating through the array using a for loop. We start at index 0, and continue until the index value (a) is one less than the length of the array. So array1[a] will give us the value that was assigned to the element at index a.

In the for loop, we are adding the value of array[a] to the integer "value" which was initialized as 0. Therefore, the result will be the sum of all the integers in array1.

Explanation:

Microsoft Excel is a software application or program designed and developed by Microsoft Inc., for analyzing and visualizing spreadsheet documents.

A spreadsheet can be defined as a file or document which comprises of cells in a tabulated format (rows and columns) typically used for formatting, arranging, analyzing, storing, calculating and sorting data on computer systems.

Some of the terminologies and features of the Microsoft Excel software includes the following;

1. Pie chart: a chart that shows the relationship of each part to a whole.

2. Goal seek: a what-if-analysis tool that finds the input needed in one cell to arrive at the desired result in another cell.

3. Relative reference cell: in a formula, the address of a cell based on the relative position of the cell that contains the formula and the cell referred to in the formula.

4. Data marker: a column, bar, area, dot, pie slice, or other symbol in a chart that represents a single data point.

5. Chart sheet: a workbook sheet that contains only a chart.

6. What-If-Analysis: the process of changing the values in cells to see how those changes affect the outcome of formulas in a worksheet.

7. $Rate = \frac {Amount \; of \; increase}{Base}$ : The mathematical formula to calculate a rate of increase.

8. Order of operations: the mathematical rules for performing multiple calculations within a formula.

9. Formula AutoComplete: the excel feature which, after typing - and the first letter of a function, displays a list of function names.

10. Axis: a line that serves as a frame of reference for measurement and that borders the chart plot area.

11. Category axis: the area along the bottom of a chart the identifies the categories of data, also referred to as the x-axis.

12. Value axis: a numerical scale on the left side of a chart that shows the range of numbers for the data points, also referred to as the y-axis.

13. $Value \; after \; increase = Base * Percent \; for \; new \; value$ : the formula for calculating the value after an increase by multiplying the original value the base by the percent for new value.
