For the data you provided, the ordered data is: 25, 25, 29, 31, 33, 37, 38, 42, 46 The median is 33. The lower half is: 25, 25, 29, 31 The median of the lower half (Q1) is 25. The upper half is: 37, 38, 42, 46 The median of the upper half (Q3) is 42. The IQR is 42 - 25 = 17
Explanation:
Given: (See attachment for banner).
Required: Estimate of the area.
The banner has two congruent trapezoids and two congruent.
This means that, the two trapezoids have the same base lengths; the two triangles also have the same base lengths.
So, we have:
B1=1+1=2 - base lengths of both trapezoids;
B2=1*3/4+1*3/4=1.75+1.75=3.5 - base lengths of both triangles.
The banner itself is a triangle and the dimension is:
Height=2m;
Base=B1+B2;
Base=2m+3.5m=5.5m.
So, the area is:
Area=0.5*Base*Height;
Area=0.5*5.5m*2m;
Area=5.5m^2.
The question asks for an estimate:
Area=6m^2.
