1. Mean of the data: 8
2. Median: 8
3. IQR = 4
4. Members that use the facility 10 days a month is: 2.
See reasons below.
<h3>What is the Mean, Median, and Interquartile Range of a Data?</h3>
Mean = sum of all values ÷ number of data values (easily solved using a dot plot
Median = middle value (easily found using a box plot).
Interquartile range (IQR) = Q3 - Q1 (easily found using a box plot).
1. Mean of the data: use the dot plot.
Reasoning: (3 + 3 + 5 + 6 + 6 + 7 + 8 + 8 + 8 + 9 + 10 + 10 + 11 + 12 + 14)/15 = 8
2. Median of the data set: Using the box plot, it is the value indicated by the vertical line that divides the box.
Median = 8
3. IQR = Q3 - Q1 = 10 - 6
IQR = 4
4. Members that use the facility 10 days a month, using the dot plot is: 2. 10 has 2 dots.

Answer:
a. 1 triangle
Step-by-step explanation:
measure line QS=8.cm measure 85°on side Q
It's 3 vertices, hope this helps!
B the only solution is X=9/10 therefore making it only one solution
X= miles driven in April
(253 + 277 + 280 + x)/4= 284
add in parentheses
(810 + x)/4= 284
multiply both sides by 4
810 + x= 1136
subtract 810 from both sides
x= 326 miles
ANSWER: She must drive 326 miles in April to average at least 284 miles January through April.
Hope this helps! :)
