The answer is B) 2 and 3
When you do a Riemann's sum, you split the interval into columns. In choice 3 we are told that there are 4 equal subdivisions meaning that each of the 4 columns are 1 wide. Since it is a left Riemann's sum we add the height of the column where the LEFT side crosses the curve. For [-1, 0], the height is -1, for [0, 1] it is 0, for [1, 2] it is 2, and for [2, 3] it is 3. Now add the heights together to get 4. Then you multiply by the width, but since the columns are 1 wide, the answer is still just 4.
Answer: I found a video about it a couple days ago, but there are no links allowed here, maybe look up on (look below they wouldn't let me put it) , How to Solve Equations on what you need help with in parentheses. Sorry, I couldn't help here. Xd Thx
United States Department of Labor's Bureau of Labor Statistics should be the answer.
Answer:
Ecological niche is a term for the position of a species within an ecosystem, describing both the range of conditions necessary for persistence of the species, and its ecological role in the ecosystem. Ecological niche subsumes all of the interactions between a species and the biotic and abiotic environment, and thus represents a very basic and fundamental ecological concept. The tentative definition presented above indicates that the concept of niche has two sides which are not so tightly related: one concerns the effects environment has on a species, the other the effects a species has on the environment. In most of ecological thinking, however, both meanings are implicitly or explicitly mixed. The reason is that ecology is about interactions between organisms, and if persistence of a species is determined by the presence of other species (food sources, competitors, predators, etc.), all species are naturally both affected by environment, and at the same time affect the environment for other species.

Answer:
Temperature is independent variable whereas, test performance is dependent.
Explanation:
Temperature is something that can be manipulated, and change in performance does not depend on the other hence it is independent. Test dependance is dependent because temperature depends test performance, and test performance cannot be manipulated.
