Given information-

A four by four table in given for the survey of the 7th and 8th group students for the movie preference.

The first column has no label with entries drama, action, comedy, total.

The second column is labeled 7th with entries 11%, 25%, 14%, 50%.

The third column is labeled 8th with entries 15%, 19%, 16%, 50%.

The fourth column is labeled total with entries 26%, 44%, 30%, 100%.

<h3>Table </h3>

A table is a arrangement of the data or the information

Now look at the statement.

  • 1) More 7th graders were surveyed than 8th graders- As both 7th grade and the 8th grade student surveyed are 50 percent. Thus the statement 1 is incorrect.
  • 2) The marginal relative frequency for action movies is 44%-Total 7th grade students like the action movies are 25 percent. Total 8th grade students like the action movies are 19 percent. The sum of both is 44 percent. Thus this is correct statement.
  • 3) The joint relative frequency for 8th graders who like comedy movies is 16%- From the table it can be said that the frequency of the 8th grade students likes the comedy movie is 16 percent. Thus this is a correct statement.
  • 4) Most students prefer drama movies- The highest number of the movie preferred by the students is action movie. Thus this is an incorrect statement.
  • 5) Half of the 7th graders prefer action movies- The 50 percent of the 7th grade is surveyed in which 25 percent like the action movie.25 is the half of the 50. Thus it is a correct statement.

Hence for the given table statement second, third and fifth are the correct statements.

Calculate the slope of the line on the graph
Tamiku [17]

Answer:

3.5 (meters per second)

Step-by-step explanation:

To calculate the slope, we need two points. Let's see if we can select two points from the graph.

From the graph, we can pick out two possible points.

At the beginning, (0,2.5) is a valid candidate.

And at the end, with (5,20). Thus, let's use the slope formula to calculate the slope.

The slope formula is:

m=\frac{y_2-y_1}{x_2-x_1}

Let (0,2.5) be x₁ and y₁ and let (5,20) be x₂ and y₂. Thus:

m=\frac{20-2.5}{5-0}

Simplify:

m=\frac{17.5}{5}\\ m=3.5

Thus, the slope is 3.5 meters per second.

Further notes:

And the entire equation will be:

m=3.5s+2.5
