I can't answer this upside down right now..
Mind taking the picture the other way?
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.
See the respective Histograms attached.

Answer
B and A
Step-by-step explanation:
Y = x + 7
m1 = 1
m1 × m2 = - 1
1 × m2 = - 1
m2 = - 1
- 1 = - 1(-1) + c
- 1 = 1 + c
c = - 2
y = - x - 2
x + y = - 2
- x - y = 2
the answer is the 2nd one
