Answer:
1. This is a "RANDOMIZED CONTROLLED EXPERIMENT".
A randomized controlled experiment is a type of research study, were the researcher randomly select samples in other not to be biased. This samples are separated into two groups, which are the experimental and the controlled group.
2. The research has a treatment group and a controlled group.
A treatment group are those group that received some special treatment from the researcher, it can also be called the experimental group. According to the research, the treatment group are those who are in the POVERTA scheme. That is the 320 communities.
A controlled group are those group that were not given any special treatment, but are , separated and studied. According to the research the controlled group are those 185 communities
3. This research provides evidence that being in a community receiving POVERTA benefits is associated with a lower rate of childhood illness. Because after two years, it was noticed the children in the community that receives POVERTA has low rate of illness, than the children in a community that doesn't receive the benefits of POVERTA.
4. This study does not provide evidence that being in a community receiving POVERTA benefits causes a lower rate of childhood illness. Because the research did not involve treatment of illnesses and they is no experimental evidence that shows that POVERTA benefits is interrelated with illness, as illness involves the internal functions of human body.
5. Such study will be called a "RANDOMIZED CONTROLLED EXPERIMENT". Because their randomly isolated themselves, and the POVERTA treatment was not given to them. The researcher was not based in selecting them not to participate.
The order in which the two transformations in a composite transformation affect the final answer
<h3>How to determine the composite transformation?</h3>
To determine if order matters or not, I will use the following example and illustration.
Let the coordinate of point A be:
A = (2, 5)
Perform the following transformations:
- Translate by (x, y + 1)
- Dilate by a scale factor of 2
First order: Translation before dilation
The translation by (x, y + 1) would give:
A' = (2, 5 + 1)
A' = (2,6)
The dilation by a scale factor of 2 would give
A" = 2 * (2,6)
A" = (4,12)
Second order: Dilation before translation
The dilation by a scale factor of 2 would give
A' = 2 * (2,5)
A' = (4,10)
The translation by (x, y + 1) would give:
A'' = (4, 10 + 1)
A'' = (4,11)
See that the final coordinates in both orders are not the same.
Hence, the order in which the two transformations in a composite transformation affect the final answer

Answer:
One triangle
Step-by-step explanation:
-The triangle's dimensions are defined and fixed.
-Given the fixed dimensions, only one unique triangle can be constructed.
-Hence, only one triangle of the dimensions 7.2cm, 6.9cm and 12.8 cm can be formed.
