Solution Steps

Step 1: Calculate the Density of the Unknown Liquid

To calculate the density of the unknown liquid, we use the formula: $$\text{Density} = \frac{\text{Mass}}{\text{Volume}}$$ Given that the mass of the unknown liquid is 728 g and the volume is 577 cm^3, the calculated density is 1.262 g/cm^3 after rounding to 3 decimal places.

Step 2: Compare the Calculated Density with Known Densities

We compare the calculated density with the known densities of possible liquids. The calculated density closely matches the density of glycerol, with a difference of 0.001 g/cm^3.

Final Answer:

The unknown liquid is likely glycerol, based on its density.

Question 10 (1 point) You determine there is a strong linear relationship between two variables using a test for linear regression. Can you immediately claim that one variable is causing the second variable to act in a certain way? No, the correlation would need to be a perfect linear relationship to be sure. No, you must first decide if the relationship is positive or negative. Yes, a strong linear relationship implies causation between the two variables. No, you should examine the situation to identify lurking variables that may be influencing both variables.
