Which of these samples is a valid random sample for the population given? Alia questions three students from her class to learn
wel
D is the answer to the question.  

To understand these questions, first look at the way the answers are written out.  Alia questions three students from her class, that might be an answer, but she didn't randomly pick them.  Miles randomly surveys a group of customers at a coffee shop, that might be one, but he might have surveyed a 25 year old instead of a 24 year old, so thats not one.  Carson interviews students working part-time to gather data, he didn't select random students, he interviewed all of them, so that is not a valid option.  Lea speaks with the managers at half of the town's 10 supermarkets, which stock similar items, to find out which breakfast cereal is most popular among the town's residents, that one is not stating that she interviewed, but she interviewed half of the 10, which is five, which can be selected randomly.  

So the correct answer is D.

A pound of chocolate costs 8 dollars. Kala buys p pounds. Write an equation to represent the total cost c that Kala pays.
ASHA 777 [7]

Answer:

8p=c

Step-by-step explanation:

For questions like this, it isn't asking for a numerical answer or anything complicated. It's mainly just using common sense and figuring out what you would do if you had actual numbers instead of variables. You would multiply the amount of pounds (p) by the cost per pound of $8, and that would be your answer (c). I hope I could help.
