Which is the best way to choose a random sample of people from a sold-out movie audience for a survey?

The best way is to completely randomize the people you pick, and get a large array of diverse people. People of different ages, sizes, living in different places. You can do this by gathering all of the people’s phone numbers, randomizing them, then calling quite a few. Make sure you get many people. This way, it will be unbiased.

Hope this helps! Comment if you have any questions or concerns! :)

Plastic Knives are sold in packs of 18 for 45p. Plastic Forks are sold in packs of 15 for 41p. Jace wants to buy the same number

Flauer [41]

Answer:

430p

Step-by-step explanation:

For this, we'll find the least common multiple for 15 and 18.

=> The least common multiple for 15 and 18 is 90

Plastic Knives:

Jace will buy 90 knives.

=> Packets = 90/18 = 5 Packets

Money for 5 Packets = 5 * 45

=> 225p

Plastic Forks:

Jace will buy 90 forks also.

=> Packets = 90/15 = 6 Packets

Money fro 6 packets = 6 * 41

=> 205p

Least Amount of Money Jace will spend = 225p+205p

=> 430p
