<em>(I dunno if you know how to find the area of the trapezoid, so I included this wordy directions) </em>
Add the top/first base plus the second/bottom base together.
Multiply that with the height.
After, divide that by two.
3 cm + 6 cm = 9 cm
9 cm x 4 cm = 36 cm
36 cm /2 = 18 cm
Area of trapezoid: 18 cm^2
So using the given information about (original) larger area of trapezoid being 72 cm^2,,,
,,,we would get 1/4 if we divide 18/72.
(scale factor)^2 = (1/4)
= 1/2
<h2>ANSWER: Scale factor is 1/2</h2>

Step-by-step explanation:
(a)
the probability of parcels weighing 35oz or less is
0.841
the probability of parcels weighing 14oz or less is
0.023
the probability of parcels weighing between 14 and 35oz is the probabilty of 35oz minus the probability of 14oz
0.841 - 0.023 = 0.818
the percentage is the probability × 100 = 81.8%
(b)
the probability of parcels weighing more than 49oz is 1 minus the probability to weigh less than 49oz.
the probability to weigh less than 49oz is
0.99865
so, the probability to weigh more than 49oz is
1 - 0.99865 = 0.00135
the percentage is again probability×100 = 0.14%
