Let the width be x.
Width = x
Length = 4x + 7
The area is 650 m²
x(4x + 7) = 650
4x² + 7x - 650 = 0
Using quadratic formula:
a = 4, b = 7, c = -650
Width = 11.9m
Length = 4(11.9) + 7 = 54.6m
Answer: Length = 54.6m and width = 11.9m
Width = x
Length = 4x + 7
The area is 650 m²

Step-by-step explanation:
Given that a random sample of 1016 adults in a certain large country was asked "Do you pretty much think televisions are a necessity or a luxury you could do without?"
Of the 1016 adults surveyed, 517 indicated that televisions are a luxury they could do without.
To find out the point estimate of population proportion of adults in the country who believe that televisions are a luxury they could do without.
We find that point estimate is nothing but sample proportion
Sample proportion = favourably voters/total people surveyed
=
