Consider the following time series: t12345 6 11 9 14 15 a. Construct a time series plot. What type of pattern exists in the data

Kindly check explanation and attached picture

Step-by-step explanation:

Given the time-series data:

Time (x) : 1 - - 2 - - 3 - - - 4 - - - 5

Data (yt) :6 - - 11 - - 9 - - 14 - - 15

The pattern which exists within the data is a linear pattern which could be inferred through the observable decrement and Incremental change in the y values at a steady or constant rate with time. The second attachment shows the linear trend line of the data.

Given:

Consider the expression is:

To find:

The like terms that can be combined in this expression.

Solution:

Two terms are called like terms, if they have same variables of same degree.

We have,

In the given expression, the pairs of likes terms are:

Pair 1: and

Pair 2: and

It means can be combined with and   can be combined with .

Therefore, the correct option is C.
