To solve the problem, we need to identify the term used for a piece of information shown in a graph that is assigned to the data series.
1. Understanding the Components:
2. Analyzing the Question:
The question states that it is a piece of information assigned to the data series and shown in a graph. This best describes a data point, which is the actual graphical representation of the value in the chart.
Final Answer:
Correct Option: (A) data point
A racing track is built around an elliptical ground whose equation is given by \[ 9x^2 + 16y^2 = 144 \] The width of the track is \(3\) m as shown. Based on the given information answer the following: 
(i) Express \(y\) as a function of \(x\) from the given equation of ellipse.
(ii) Integrate the function obtained in (i) with respect to \(x\).
(iii)(a) Find the area of the region enclosed within the elliptical ground excluding the track using integration.
OR
(iii)(b) Write the coordinates of the points \(P\) and \(Q\) where the outer edge of the track cuts \(x\)-axis and \(y\)-axis in first quadrant and find the area of triangle formed by points \(P,O,Q\).
