A student is assessing the correlation between the average number of hours of internet browsing and average score on a math test for the students of a class. The table below shows the data: Number of hours of internet browsing

(x) 0 0.5 1 1.5 2 2.5 3 3.5 4 4.5

Score on math test

(y) 95 94 93 92 91 90 89 87 86 85

Part A: Is there any correlation between the average number of hours of internet browsing and average score on the math test for the students of the class? Justify your answer.

Part B: Write a function which best fits the data

Part C: What does the slope and y-intercept of the plot indicate?

Part A:

Yes, the correlation is that the longer time a student  spends browsing the internet, the worse score the student will receive on the test.

Part B:

y= - 1/2x + 95

Part C:

The slope of the line is -1/2, which represents for every additional hour of internet browsing, the student loses 2 points. The y intercept is 95, which represents a max  score of 95.

sry but any answer choices

ratios represent a pattern or relationship that can be scaled.

equivalent ratios are pairs of ratios that represent the same relationship between quantities, and can be generated by multiplying or dividing both quantities in the ratio by the same factor.

in this lesson, students will use double number lines and ratio reasoning to solve ratio problems. by partitioning double number lines into proportionate intervals, students will build an understanding of equivalent ratio relationships as those that are generated by multiplying or dividing two related quantities by the same number. this lesson will build upon students' prior understanding of multiplicative comparisons, number line reasoning and equivalent fractions (while highlighting the difference between equivalent fractions and equivalent ratios); and will build toward future work in this unit on building ratio tables, and work in future grades in proportionality, scaling, and expressing and graphing linear functions.
