Students measure their heights, arm lengths, and stride lengths to determine whether there is a relationship among the values. which type of graph should the students use to display their data?
line graphscatter plotbar graphhistogram

The correct option is 2. The student should use scatter plot to display their data.

Step-by-step explanation:

It is given that the students measure their heights, arm lengths, and stride lengths to determine whether there is a relationship among the values.

Line graph: Line graph is a continuous graph, which is generated by connecting the points of scatter plot. Generally, they are used to describe the value of something over time.

Scatter plot: The data points are plotted in a coordinate plane. Where each point defines the value of y with respect to x. Scatter plot is used for random data.

Bar graph: It is used to compare changes between different groups or data over the time.

Histogram: It is used to describe the frequency of continuous data.

The measure of their heights, arm lengths, and stride lengths is a random data. So, the student should use scatter plot to display their data.

Therefore, the correct option is 2.

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
