Integers were used in the 15th century by European traders to label barrels of grain or flour. For example, a barrel that was 1 pound too heavy was labeled +1, and a barrel that was 1 pound too light was labeled –1. A trader checked twenty 50-pound barrels and found the labels to be: five –3s, nine –5s, two +4s, and four –8s. Find the actual total weight of the barrels.​

Kevin went fishing and is using a scatterplot to analyze the relationship between the weight of each of the fish he caught in pounds and in kilograms. he uses the weight in pounds as the independent variable and the weight in kilograms as the dependent variable. which statement is correct? the points on the scatterplot will go up from left to right because as the weight in pounds increases, the weight in kilograms increases. the points on the scatterplot will go up from left to right because as the weight in pounds increases, the weight in kilograms decreases. the points on the scatterplot will go down from left to right because as the weight in pounds increases, the weight in kilograms increases. the points on the scatterplot will go down from left to right because as the weight in pounds increases, the weight in kilograms decreases.
