Some friends went to lunch and split the bill equally. If each person paid $6.75, how many people went to lunch thinking. Use a diagram or equation to explain your thinking. The total is 27$. 27 divided by 6.75 is 4. Suppose
Answer: c) About 16% of the variation in value of the car is explained by a linear relationship with the age of the car.
e) The correlation coefficient, r, is 0.397.
Step-by-step explanation:
Given that:
Coefficient of determination (r²) between two variables, age of car (x) and value of car (y) = 0.158
Correlation of determination (r²) of 0.158 = (0.158 × 100% = 15.8% of the variation between the two variables can be explained by the regression line). Hence, about 16% of the variation between age and value of car can be explained by the linear relationship.
Coefficient of correlation (r) = sqrt(r²) = sqrt(0.158) = 0.397
3/6 (r-7) =1 The answer is r=7
