Answer:
Relative frequency
0.214
0.268
0.446
0.071
Total 1
Step-by-step explanation:
The relative frequency is computed by dividing the individual frequencies to the sum of frequencies.
sum of frequencies=12+15+25+4=56
Class Relative Frequency
10-20 12/56=0.214
20-30 15/56=0.268
30-40 25/56=0.446
40-50 4/56=0.071
Total 12/56+15/56+25/56+4/56=56/56=1
The area of the trapezoid can be calculated through the equation,
A = (b₁ + b₂)h / 2
where b₁ and b₂ are the bases and h is the height. Substituting the known values from the given,
A = (25mm + 32mm)(15 mm) / 2
A = 427.5 mm²
Since there are two trapezoids in the necklace, the area calculated is to be multiplied by two to get the total area.
total area = (427.5 mm²)(2)
<em>total area = 855 mm²</em>
