Answer:
10x + 4
Step-by-step explanation:
Combine like terms.
First combine the numbers that have the letter x:
- <u>-3x</u> <u>+ 8x</u> + 2 <u>- 3x</u> <u>+ 8x</u> + 2
- <u>-3x + 8x -3x +8x</u> + 2 + 2
- <u>10x</u> + 2 + 2
Then combine the ones that don't have the letter x
- 10x <u>+ 2</u> <u>+ 2</u>
Answer is 10x+4
Answer: A. Paul’s data has a bigger overall spread than Sally’s data
The range of Paul’s Data: 28-12=16
The range of Sally’s Data: 30-15=15
16>15. Therefore Paul’s data has a bigger overall spread than Sally’s
Why B is wrong: Remember that the interquartile range is the “box” range.
Paul’s IQR: 26-15=11
Sally’s IQR: 28-18=10
11<10 is false, so B is false.
Why C and D is wrong: The middle line in the IQR represented in each box and whisker plot is the median. Paul’s median is not equal nor greater than Sally’s median. 18=24 18<24 is false. Therefore, C and D are false.
Answer:
10
Step-by-step explanation:
