Based on the data, what is the most reasonable estimate for the number of Timpony School District
middle school students who average watching more than 4 hours of TV each day?
Choose 1

267 students.

Step-by-step explanation:

Let x be the total number of students who average watching more than 4 hours of TV each day.

We have been given that Timpony School District surveyed a random sample of 60 middle school students about the amount of time they watch TV. Of the students surveyed, 14 average watching more than 4 hours of TV each day.  

So the probability of a student watching more than 4 hours of TV each day will be

To find the estimated number of students, who watch the TV more than 4 hours each day, we will use relative probability as it is the ratio of the occurrence of a singular event and the total number of outcomes.

So we can set a proportion as:

Upon dividing both sides of our equation by 1143 we will get,

Therefore, approximately 267 students of Timpony School District middle school average watching more than 4 hours of TV each day.

your answer is the last one

step-by-step explanation:

divide the length of a'c' by the length of ac to get a scale factor of two

& then reflect vertically (over the y-axis)

so your answer is dilation by a scale factor of 2 followed by reflection over the y-axis
