@icedipping ^^ the table below shows the volume of two samples, x and y, when placed in three containers of different volumes. volume of samples volume of container volume of sample x volume of sample y 200 ml 200 ml 200 ml 500 ml 200 ml 500 ml 600 ml 200 ml 600 ml which of the following correctly describes the state of matter of one of the samples? y is a gas because it has a definite volume. x is a liquid because it has a definite volume. y is a liquid because it fills up the entire container. * x is a gas because it fills up the entire container. the table below shows the dimensions of two colored cubes. dimensions of cubes cube side (cm) mass (g) yellow 3 135 black 2 48 which cube is denser? black, because it has less volume and less mass. yellow, because it has more volume and more mass.* black, because the product of its side and mass is lower. yellow, because the product of its side and mass is higher. the table below shows some physical properties of two unknown samples. physical properties sample mass solubility (in water) c 200 g 36 g/ml d 500 g 180 g/ml what would best support whether the two samples are of the same substance or not? the two substances are the same because the property that depends on the amount of the sample is different. the two substances are the same because the property that is independent of the amount of the sample is different. the two substances are not the same because the property that is independent of the amount of the sample is different.* the two substances are not the same because the property that depends on the amount of the sample is different.

The chemical composition of soil varies with depth. an article in communications in soil science and plant analysis describes chemical analyses of soil taken from a farm in western australia. fifty specimens were each taken at depths 50 and 250 cm. at a depth of 50 cm, the average no3 concentration (in mg/l) was 88.5 with a standard deviation of 49.4. at a depth of 250 cm, the average concentration was 110.6 with a standard deviation of 51.5. find a 95% confidence interval for the difference in no3 concentrations at the two depths.
