Yes because 8 is bigger than 3.
Let the score on her seventh test be "x".
SO,

∴ He must get 104% on his seventh test to get an average score of 90%
The volume of the cylinder is 4710 cubic inches
Step-by-step explanation:
Volume of the cone = 1570 cubic inches
Volume of cone = 1/3(volume of the cylinder)
So,
Volume of the cylinder = 3(volume of the cone)
Volume of the cylinder = 3(1570)
= 4710 cubic inches
The volume of the cylinder is 4710 cubic inches
Answer:Average error will be less
Step-by-step explanation: Prediction error refers to the difference between the the actual and predicted value of an observation. Using correlation analysis or study, The level or degree of correlation or relationship between two measured variables usually determines the variation or measure of the prediction error. If there is no relationship or correlation between two measured variables, if such model is used to make prediction, the average prediction error will be very high. However, since it is stated that there exist a relationship between high school GPA and Freshman-year GPA, then making prediction based on this assertion will lessen the average prediction error.
