Stan is working on a class project for which he must interview ten of his classmates. He places the names of everyone in his class into a hat and selects 10 names. What kind of sampling is this?

Stan is using a simple random sample.

Step-by-step explanation:

Because when putting the names of the students in the hat and then choosing one he is using a random sample

725 parts per hour.

step-by-step explanation:

hi there, this answer is actually really simple.

you can set it up as 1450/2 or 3625/5 to find the answer.

they want to know how much per hour is being made, so you just divide.

1450/2=725.

and that's how many are produced per hour.

hope this . : )

x = 3 ± √(5+y)
