Another name for pyramid with an equilateral base, could be a square pyramid. It could also be a triangular pyramid.
I have included a picture of each of these nets to show you the areas that would need to be calculated.
To find the area of the services on an equilateral based pyramid, you would need to find the area of the base, and the area of one triangle (lateral face). All the triangular area's leading up to the point on a pyramid would be congruent.
This means if it is a square pyramid you would have four congruent triangles.
If it is a triangular pyramid you would have three congruent triangles in addition to the triangular base.
Answer:
An independent sample.
Step-by-step explanation:
In this scenario, to compare the production techniques used by foreign and local firms in Brazil, a random sample of 80 foreign firms and a random sample of 80 local firms are selected. We can safely conclude that this study uses an independent sample design.
An independent sample design can be defined as a research method that usually involves the use of multiple experimental groups (two or more). The samples or participants are only in one group and as such each group has no relationship with the other. This simply means that, the samples in a particular group is having no relationship with the other samples in another group.
Ultimately this implies, each samples are independent and satisfies only one condition of the independent sample design during the experiment to compare the production technique used by foreign and local firms in Brazil.
<em>Hence, the researcher would use only two variables or conditions: a random sample of 80 foreign firms and a random sample of 80 local firms are selected.</em>
Answer:
I think the answer is 2.7
Step-by-step explanation:
3x√64
√64=8
3x=8
x=8/3
x=2.7
