Answer: 4 seeds will left over.
Step-by-step explanation:
Total sunflower seeds = 1354
Number of people shared sunflower seeds equally = 6
By division operation,
Number of seeds each people will get = (Total sunflower seeds) ÷ (Number of people shared seeds equally)
Hence, each people will get 256 sunflower seeds and 4 seeds will left.
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
