Answer:
add 2 subtract 2 add 8 multiply by 3 divide by 27
Meeeeeeeeeeeeeeeeeeemeemeekem
You put 15 over 65 is equal to 50 over x, then you multiply diagonally so 15x = 3250 then you divide both sides by 15 to get 216.67 which means 50 pencils equals 2.17 dollars
Answer:
0.451751 is the proportion of variability of Gini Coefficient explained by our least squares lines
Step-by-step explanation:
Given

To predict: Gini by year
Required
Interpret the R squared
