    Accuracy refers to how close a measurement is to the true or accepted value. It is a measure of how well a measurement represents the actual value being measured. A measurement can be precise, meaning it has a low level of random error, but not accurate if it is consistently off from the true value. Therefore, the extent to which a measurement approaches the true value is referred to as accurate.

     Although a measurement of 6.13457902 cm is very precise it may not be accurate.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    The statement suggests that the measurement of 6.13457902 cm is precise, meaning it has a high level of detail or specificity. However, it also states that this measurement may not be accurate, implying that it may not be close to the true or correct value. Therefore, the statement is true because precision does not guarantee accuracy.

    Is the following statement an observation or an inference? "The two police officers in the picture are guarding the street beacuase a crime was commited" 

    • A.

      Observation

    • B.

      Inference

    Correct Answer
    B. Inference
    Explanation
    The statement is an inference because it goes beyond the information provided in the picture and makes a conclusion based on that information. The picture only shows two police officers on the street, but it does not provide any direct evidence that a crime was committed. The statement assumes that the presence of the police officers is due to a crime being committed, which is an inference made by the person making the statement.

    What is the most likely reason  the ridership increased and the casualties decreased in NYC from 1998-2008? 

    • A.

      NYC sold more bikes

    • B.

      NYC made bicycle lanes on most downtown roads

    • C.

      NYC had more people riding bikes

    • D.

      NYC riders did not go out at night

    Correct Answer
    B. NYC made bicycle lanes on most downtown roads
    Explanation
    The most likely reason for the increase in ridership and decrease in casualties in NYC from 1998-2008 is that NYC made bicycle lanes on most downtown roads. By creating dedicated lanes for bicycles, it provided a safer and more accessible environment for cyclists, encouraging more people to ride bikes. This increase in the number of people riding bikes would naturally lead to an increase in ridership and a decrease in casualties as the infrastructure became more accommodating to cyclists.

      Does Tobacco Tax or Fuel Tax generate more funds for the Government?

    • A.

      Tobacco Tax

    • B.

      Fuel tax

    Correct Answer
    A. Tobacco Tax
    Explanation
    Tobacco tax generates more funds for the government compared to fuel tax. This is because tobacco products are heavily taxed due to their harmful effects on health and society. The high tax rates on tobacco products result in a significant revenue stream for the government. On the other hand, fuel tax, although it also contributes to government revenue, is generally lower in comparison. Additionally, the demand for tobacco products is relatively inelastic, meaning that even with higher taxes, people continue to purchase them, further increasing the funds generated for the government.

    Which type of sleeper takes more total breaths per minute? 

    • A.

      Person with Normal Sleep

    • B.

      Person with Apnea Sleep

    Correct Answer
    B. Person with Apnea Sleep
    Explanation
    A person with apnea sleep takes more total breaths per minute because apnea is a sleep disorder characterized by pauses in breathing or shallow breaths during sleep. These pauses can occur multiple times throughout the night, causing the person to take more breaths per minute in order to compensate for the interrupted breathing.

    Do chemical or physical properties involve forming a new substance?

    • A.

      Chemical

    • B.

      Physical

    Correct Answer
    A. Chemical
    Explanation
    Chemical properties involve the formation of a new substance. This means that when a chemical change occurs, the original substance is transformed into a different substance with new properties. This can involve a variety of processes such as a reaction with another substance, a change in molecular structure, or the release of energy. In contrast, physical properties do not involve the formation of a new substance. They describe the characteristics of a substance that can be observed or measured without changing its chemical composition.

  • 48. 

    Is the oxidation of a substance a chemical or physical property?

    • A.

      Chemical

    • B.

      Physical

    Correct Answer
    A. Chemical
    Explanation
    The oxidation of a substance is a chemical property because it involves a chemical reaction where the substance combines with oxygen or loses electrons. This process leads to a change in the chemical composition of the substance, resulting in the formation of new compounds or the alteration of its properties. Physical properties, on the other hand, are characteristics that can be observed or measured without changing the substance's chemical composition. Since oxidation involves a chemical reaction and leads to a change in composition, it is considered a chemical property.
