Answer:
1/2
Step-by-step explanation:
3x=(1/2)(2x+2)
3x=x+1
3x-x=x-x+1
2x=1
x=1/2
Answer:
1/30=x/180
Step-by-step explanation:
The way that Ronnie wrote his proportion is wrong since 180/x is saying that he will miss 180 days of school. The fraction 1/30 means that he would miss 1 day out of 30 days, which is correct. But the fraction 180/x would mean that he is missing 180 days of school, which is wrong.
Solving:
1/30=x/180
180/30=6
1 x 6 = 6 days
He will miss 6 days of school in 180 days.
Answer:
1. 2
2. 6
3. 2
4. 3
5. 1
6. 1
Step-by-step explanation:
First put the data in order from smallest to largest
2,2,2,3,3,6
The minimum is 2
The maximum is 6
The median is 2,2,2 ,3,3,6 is between the 2 and 3 (2+3)/2 = 2.5
The 1st quartile is 2,2,2 is the middle number = 2
The third quartile is 3,3,6 is the middle number is 3
The interquartile range is 3-2 =1
The mean average deviation is
First find the mean: ( 2+2+2+3+3+6)/6 =18/6 = 3
Then find how far each point is from the mean
(3-2) + (3-2) + (3-2) + (3-3) + (3-3) + (6-3) = 6
Divide this by the number of data points
6/6 =1
