Answer:
The investment has doubled in worth by the start of 15th year.
Explanation:
The answer is Count. Count is an aggregate method in SQL that returns the number of rows for a specified column that have non-null values.
<h3>What is the Meaning of Null?</h3>
When a field in a database has no values at all, this is known as null and indicates that the field’s value is unknown.
A null value for a number field, text field, or space value is different from a zero value. Null indicates that no value has been recorded in a database field.
A value and a null cannot be compared. The Structured Query Language query cannot be written as SELECT * FROM Customer where email Address=null, for instance, if it is intended to obtain all customers without email addresses from a Customer Addresses table.

Postponement warehousing is a form of warehousing that combines classic warehouse operations with light manufacturing and packaging duties to allow firms to put off final assembly or packaging of goods until the last possible moment
<h3><u>Explanation:</u></h3>
Postponement warehousing involves modifications that can be done in the entire supply chain management line until the last moment when the product would be delivered. The manufacturer at the beginning creates a generic product and moves it forward for modifications as required or demanded by the end user or customer.
In such cases customization is more prevalent and risk is minimized as current investment into a product or service is delayed until the last resort. Some of its types can be, labeling, packaging, manufacturing and time postponements.
