Question

Number 12 multiple choice use the graph for the answer above

Answer 1

The question revolves around the use of graphing tools to interpret and analyze data on various graphical representations, such as plotting probabilities, identifying relationships, and interpreting trends in datasets.

Step-by-step explanation:

The subject matter of the multiple-choice question number 12 pertains to the use of graphing calculators, software, or binomial tables to interpret and analyze data represented on graphs. Students are expected to employ these tools to find probabilities, trends, and patterns within various graphical representations such as histograms, scatter plots, and displacement-time graphs. For example, using a graphing calculator, one can calculate the probability of a random variable being less than or equal to a certain value (P(x ≤ 12) = .9738).

Additionally, students are prompted to create and interpret different types of graphs such as stem-and-leaf plots (stemplots), line graphs, and bar graphs. An underlying skill in plotting these graphs involves understanding the relationship between independent and dependent variables, which is crucial when determining the best fit line or linear regression model for a given data set.

Answer 2

The acceleration of an object is the time rate of change of velocity.

That is, the acceleration is given by,

`a=(\Delta v)/(\Delta t)`

Where Δv is the change in the velocity and Δt is the time period.

Thus the acceleration is change in the velocity divided by time

Thus the correct answer is option c.
