The data consists of 25 observations - this is just how many people were involved in the study. (count the rows, excluding the header)
As for number of variables, that depends on the aim of the study. More likely than not, I suspect the name of each person involved is irrelevant, which leaves 7 variables. (count the columns, excluding the first)
Between 1994 and 1998 the population increased by 5 miliion, approximately 1 1/4 million a year.
2016 - 1998 = 18 years at 1 1/4 million a year = 22 1/2 million
Estimate therefore is: 81 + 22 1/2 = 103 !/2 million
The awnser IS no it is not a true statement
Answer:
What is your question supposed to be? It's just a bunch of gibberish.
Answer:
The linear equation in two variables is 5u - 8v = 150 .
Step-by-step explanation:
As given
The cost of 5 tables exceeds the cost of 8 chairs by Rs150 .
Let us assume that the cost of one table be u .
Let us assume that the cost of one chairs be v .
Than the equation becomes
5u + 150 = 8v
Simplify the above equation
5u - 8v = 150
Therefore the linear equation in two variables is 5u - 8v = 150 .
