If A,B and C lie on the same line:
4x- 9 + 3x+5 = 17
7x = 21
x = 3
The mean, median, standard deviation, and interquartile range for each data set is given below.
<h3>What is the definition of Interquartile Range (IQR)?</h3>
When arranged from lowest to highest, the IQR represents the central 50% of values.
Find the median (middle value) of the lower and higher half of the data to get the interquartile range (IQR).
These are the quartile 1 (Q1) and quartile 3 (Q3) values (Q3). The difference between Q3 and Q1 is the IQR.
<h3>What are the measures of central tendency for Manuels Data?</h3>
Using the statistical tool, the following were arrived at:
- Standard Deviation = 3.13961
- Mean = 8
- Median = 8
- IQR = Q3-Q1 = 10 - 6 = 4
<h3>What are the measures of central tendency for Grethcen's Data?</h3>
Using the statistical tool, the following were arrived at:
- Standard Deviation = 4.68737.
- Mean = 9.6
- Median = 9
- IQR = IQR = Q3-Q1 = 12 - 7 = 5.

Answer: 5.824 m / min
Step-by-step explanation:
Change in position = -2.1m to -38.6m
Distance = |-38.6 m - (-2.1m) |
=|-36.5| m
= 36.5 m
Time = 

The average change in Michelle's position each minute = 

Hence, the average change in Michelle's position each minute = 5.824 m / min
Answer:
-12x+20
Step-by-step explanation:
Subtract similar numbers:
2x - 14x = -12x
Product:
12 - 12x + 8
Group the terms that are similar:
-12x + 12 + 8
Add the numbers:
-12x + 20
Final answer:
-12x + 20
