Answer :
The answer will be 60+ because 48 minutes is a long time and if youstudy for a long time you memorize more
To predict the test score for someone who spends 48 minutes studying, the equation of the line of best fit from a scatter plot relating study time to test scores is used, substituting 48 as the x-value in the equation.
The student is inquiring about predicting a test score based on the amount of time spent studying by using a scatter plot and a line of best fit. To predict the test score for someone who spends 48 minutes studying, one would typically use the equation of the line of best fit derived from a scatter plot of existing data points that relate study time to test scores.
Firstly, the data would be plotted on a scatter plot, showing study time on the x-axis and test scores on the y-axis. Then, we calculate the line of best fit, often using the least squares method. This line minimizes the sum of the squares of the vertical distances (residuals) between the observed values and the values predicted by the line.
Once the line of best fit is determined, its equation can be used to predict the test score. For example, if the equation is y = mx + b, where m is the slope and b is the y-intercept, we would plug in 48 for x to find the predicted test score y. Without the actual data points or the equation of the line of best fit, we cannot provide a specific predicted score for the 48 minutes of study time.
