Based on the data from six students, the regression equation relating number of hours of preparation (x) and test score (y) is . the same data yield and what is the best predicted test score for a student who spent 10 hours preparing for the test?

The predicted test score for a student who spent 10 hours preparing for the test is 78.

Step-by-step explanation:

The regression equation is used to determine the predicted value of the response or dependent variable based on an explanatory or independent variable.

The general form of a regression equation is:

Here,

y = dependent variable

x = independent variable

α = intercept

β = slope

The regression equation relating number of hours of preparation (x) and test score (y) is:

Compute the value of y for x = 10 as follows:

Thus, the predicted test score for a student who spent 10 hours preparing for the test is 78.

2/4 is the answer

step-by-step explanation:

x= total pieces

both ate 9 pieces

mindy ate 3 so troy ate 6

6= (1/4)x

x =24
