Lynn asked six friends how many cars their parents own. She recorded 1, 1, 2, 2, 2, and 4 cars. What is the mean absolute deviation of the number of cars? Round to the nearest tenth, if needed. A. 0.7 cars B. 1.1 cars C. 1.4 cars D. 2 cars

Answers

Answer 1

Answer: To find the mean absolute deviation, you have to find the mean first.
1+1+2+2+2+4=12
12 divided by 6 numbers=2 The mean of that is two
Next, you have to find the amount the original numbers are away from the mean.
1= 1 away from 2 2=0 away from 2 4=2 away from 2
You should get: 1,1,0,0,0,2 Next, you have to find the mean of the new set of numbers. 1+1+0+0+0+2=4
4 divided by 6= 2/3
The mean absolute deviation is 2/3

Answer 2

Answer:

the anwser is a 0.7

Answer:

D. $A\subset \mathbb{R}*\mathbb{R}.$

Step-by-step explanation:

Consider the set

$A=\left\{(2,3),\ (5,1),\ (-3,-2),\ (0,3)\right\}$

This set consists of four ordered pairs.

The first numbers in these pairs are $2,\ 5,\ -3,\ 0.$ These numbers are integer numbers (not natural, because -3 is negative).

The second numbers in these pairs are $3,\ 1,\ -2,\ 3.$ These numbers are integer numbers too (not natural, because -2 is negative).

Options contain only natural and real sets, so, the first and the second numbers are real numbers and

$A\subset \mathbb{R}*\mathbb{R}.$

Answer:

D. R X R

Step-by-step explanation:

The answer is choice D because, the set of the actual numbers of R has a 0 so A is a subset of R X R

in a card game,each player is dealt 5 cards.Make a table to show the total number of cards dealt for each number of players from 3 to 6.Write each ratio of players to cards dealt.

Answers

so since each player is dealt 5 cards
ratio of cards per player is 5:1

so if 3 players
5 times 3=15 cards

4 players=4 times 5=20 cards

5 players=5 times 5=25 cards

6 players=6 times 5=30 cards

ratio of cards per player is 5:1

since each palyer gets 5 cards each then 3 people is 15 cards & 4 people is 20 cards & 5 people is 25 cards and 6 people is 30 cards all together so there will be 30 cards all together 3:15 4:20 5:25 6:30
