According to a recent survey, 50% of people aged 13 and older in the United States are addicted to texting. To simulate choosing

a random sample of 20 people in this population and seeing how many of them are addicted to texting, use a deck of cards. Shuffle the deck well, and then draw one card at a time. A red card means that person is addicted to texting; a black card means he isn’t. Continue until you have drawn 20 cards (without replacement) for the sample.

Answer:

It is not valid 49.02% instead of 50%

Step-by-step explanation:

If you don't replace the cards,the probability of obtaining a person that is addicted to email is no longer 50% after the first drawn card.

If you drawn a red card there are 25 red cards and 26 black cards then the probability of 25/25+26=25/51 ≅0.4902 = 49.02 instead of 50%

kogti [31]

Answer:

# 1 Liam is 171 miles from Troy.

#2 The ball bounces 6 times.

Step-by-step explanation:

#1 adding 147 to 47 equals 171. If Liam and Sidney are 124 miles apart and Troy is 47 more miles apart from Liam then it is adding the distance already given to the distance he is from Sidney since she is in the middle.

#2 from 40 to 20 to 20 to 10 from 10 to 5 from 5 to 2.5 from 2.5 to 1.25. Just divide by 2 till it is 2 or less than feet.
