Answer:
y=9
Step-by-step explanation:
Isolate the variable by dividing each side by factors that dont contain the variables
move variable to left side and change its sign
42-7y+3y=6 collect like terms
-7y +3y=6-42
-4y=6-42
-4y=-36 divide both sides of the equation by -4
y=9
hope that helps :)
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.
