Answer:
A, B, D
Step-by-step explanation:
A random sample is one in which every member of the population has an equal chance of being chosen.

You can buy 30 apples because 2 goes into 7 3 times. Since at a store you can’t split a pack of apple (ie. you can’t break open a box of soda cans and buy just one) you can only get what $6 will buy you. That would mean getting 10 apples multiplied by 3 (how many times $2 can go into $7) and you would get 30 apples. Hope that helped!
