Answer:
D. A random sample
Step-by-step explanation:
The answer to your question is D. A random sample because this sampling type is people being randomly selected from the population. We can also rule out the other options because of the following reasoning:
[✗] A. A convenience sample
-> This is a good contender, but as she is not asking everyone and the sample is <em>for</em> the school, it would not make sense to ask people near her house for example, we can say that this probably is not the best option.
[✗] B. A self-selected sample
-> This type is more like a poll, people volunteer for a self-selected sample, while here they are being asked
[✗] C. A systematic sample
-> Every so often she is asking students questions, she does not have a set number of how often or of the population (that we know of)
[✓] D. A random sample
-> This option is correct as stated above. She is randomly picking people.
Have a nice day!

Answer:
24
Step-by-step explanation:
Remember that there is 100 centimeters in a meter, and 1000 meters in a kilometer. If you multiply both values together (so you have a conversion of centimeters to kilometers) you get 100,000. Therefore, 100,000 centimeters makes a kilometer. Divide 320,000 by 100,000 and you get 3.2. Therefore, a centimeter would represent 3.2 kilometers.
Answer:
P = -6.4
Step-by-step explanation:
Solve for P:
P + 0.4 = -6
Subtract 0.4` from both sides:
P + (0.4 - 0.4) = -0.4 - 6
0.4 - 0.4 = 0:
P = -0.4 - 6
-0.4 - 6 = -6.4:
Answer: P = -6.4
