Alex is conducting a survey for a car company. She decides to start by interviewing some people in her neighborhood. She prepares a questionnaire and emails it to 50 neighbors who own cars. Of those neighbors, 24 respond. Why is this sample likely to be biased?

Answers

1).  Her sample is all from the same socio-economic group ... the people
who live in HER neighborhood.

2).  Even from those, she only gets any information from about half of them.

Answer:

Given scenario is :

Alex is conducting a survey for a car company. She decides to start by interviewing some people in her neighborhood.

She prepares a questionnaire and emails it to 50 neighbors who own cars. Of those neighbors, 24 respond.  

We can see that Alex sent the questionnaire to only her neighbors or people who live near her, so this will be the reason the sample will be biased.

83 tens × 2 tens =166

Answers

1 cube= 1 unit
1 Rod (Long)= 10 units
10 Rods (Longs)= 1 flat (1 flat=100 units)
10 flat =1 cube(1 cube=1000 units)
83×10= 830
2×10=20
830×20= 16,600
Just wanted to add more to help you understand why 83 is multiplied by ten and 2 is multiplied by 10. Its because when we use Base ten blocks, tens represent 1 Rod (Long)= 10 units. Hope it helps more.
That is actually not true
83 tens = 830
2 tens = 20
830x20=16600
So the answer is 16600

1/6+ (-2/3)

The correct answer is c. -1/2~
you can say -2/3 = -4/6 so : 1/6 - 4/6 = -3/6 = -1/2 and thats the simplest so the answer is c :))
