Answer:
Option A. one rectangle and two triangles
Option E. one triangle and one trapezoid
Step-by-step explanation:
step 1
we know that
The area of the polygon can be decomposed into one rectangle and two triangles
see the attached figure N 1
therefore
Te area of the composite figure is equal to the area of one rectangle plus the area of two triangles
so
![A=(8)(4)+2[\frac{1}{2}((8)(4)]=32+32=64\ yd^2](https://tex.z-dn.net/?f=A%3D%288%29%284%29%2B2%5B%5Cfrac%7B1%7D%7B2%7D%28%288%29%284%29%5D%3D32%2B32%3D64%5C%20yd%5E2)
step 2
we know that
The area of the polygon can be decomposed into one triangle and one trapezoid
see the attached figure N 2
therefore
Te area of the composite figure is equal to the area of one triangle plus the area of one trapezoid
so

In conducting a goodness of fit test, a requirement is that the expected frequency must be at least ten for each category.
<h3>What is a
goodness of fit test?</h3>
In relation to the statistical model, the test tells how well it fits a set of observations.
The measures of the goodness of fit summarize the discrepancy between observed values and the values expected under the model in question.
Also, when conducting a goodness of fit test, a requirement is that the expected frequency must be at least ten for each category.
Therefore, the Option B is correct,
