Answer:
Below in bold.
Step-by-step explanation:
Arrange the data in ascending order:
1. 1 1 2 3 4 7 9
Median = middle number = 3.
Q1 = 1
Q3 = 7.
2. 26 31 34 38 42 66 74 78
Median = mean of 2 middle numbers = 40.
Q1 = 31.
Q3 = 74.
3. 36 45 49 52 53 64 81 87 93
Median = middle number = 53.
Q1 = 47.
Q3 = 84.
Equations
a1+o1=108
a2+o2=452
a1x5=a2
o1x3=o2
Solving for # of oranges sold first week.
5a1+3o1=452
a1=108-o1
5(108-o1)+3o1=452
540-5o1+3o1=452
540-2o1=452
88=2o1
o1=44
Solving for # of apples sold first week.
a1+44=108
a1=64
64 apples were sold the first week and 44 oranges were sold the first week.
The second week sold 320 apples and 132 oranges. I hope you understand my work.
Answer:
The ordered pair (15, 12) means that 15 pounds of beans cost $12.
Step-by-step explanation:
Ordered pairs are in the format of (x,y). The first number represents a point's position on the x-axis and the second represents a point's position on the y-axis. Also note that in this graph, the x-axis represents the weight of beans in pounds and the y-axis represents the cost of beans.
Knowing this, (15,12) means that 15 pounds of beans must cost $12.
