Answer:
The correct answer is option C that is graph X.
Step-by-step explanation:
Given : 1 sack lunch has 3 sandwiches
x axis = Number of sack lunches
y axis = Number of sandwiches
The coordinate from the given data will be: (1,3)
So, from the given graphs the graph with coordinate point (1,3) is correct. It will also show change in number of sandwiches with respect to change in number of sack lunches.
Answer:
5+90m
Step-by-step explanation:
117 - 78m + 168m - 112
117- 112 = 5
-78m + 168m= 90m
5+90m
The lower quartile is quartile 1. The graph shows it as "-4". So the answer is D.
