Answer:
property of zero.
Step-by-step explanation:
It is given that, (4y + 1) × 0 = 0
. We need to tell out of four given options, which property is used in this case.
The property of zero states that if any number is multiplied by 0, then the answer is equal to 0.
Here, the number is (4y+1). It is multiplied by 0. It means that the result is 0.
Hence, it shows "property of zero".
Answer:
C. The samples are independent because there is not a natural pairing between the two samples.
Step-by-step explanation:
Independent samples are stand-alone samples. Their values do not give information about other values in another samples. They cannot be altered. Examples: To test the effectiveness of a particular drug in managing diabetes, a group of people is placed on the active drug. Another group is placed on a placebo. The two samples are independent because their values are taken from two different set of groups or people.
But a dependent sample is usually taken from the same group to test for the effectiveness of a drug before and after treatment.
