A student scored in the 60th percentile on her math exam. What does this student's score mean in relation to those of the other
Andrei [34K]

Answer:

The correct option is;

c. Her score was better than those of 60% of all test takers

Step-by-step explanation:

Percentile Score is the score of an exam or test candidate with regard to the relative performance of the other persons that took part in the exam or test.

The percentile score is calculated by converting candidates scores into a scale consisting of the scores of all candidates and ranging from 0 to 100

A 60th percentile score means that the student performed better than 60% of all the candidates of the test and 40% of the test takers scored the same as or better than the student.

The graph shows the linear relationship between the height of a plant (in centimeters) and the time (in weeks) that the plant ha
Snezhnost [94]
You did not include the graph.

Searching on internet I found a graph with which I can help you. I will solve the question using and so you can understand the problem and solve with the real graph.

1) The slope of line given the graph is calculated as:

slope = run / rise = Δy / Δx = constant.

2) So, you can choose any two points to calculate the slope.

3) Uisng the points (50,20) and (30,10) you get:

slope = [ 20 - 10] / [50 - 30] = 10 / 20 = 1/2

4) Note that that means that the plant grows 1 cm in 2 days

5) The rate of change is 1cm / 2 weeks.

With this you know how to calculate the slope, which is the same rate of change, and the meaning of it, which permits to answer the question from the complete statement and graph.
