## Evaluate $\sum_{y=0}^{2^n-1}e^{2\pi iy(z-x)/2^n}$

I am trying to evaluate $ $ \sum_{y=0}^{2^n-1}e^{2\pi iy(z-x)/2^n}$ $ where $ n\in\mathbb{Z}$ and $ x,z\in\mathbb{Z}_{2^n}$ .

Clearly, if $ x=z$ , then $ \sum=2^n$ . But I am unsure about when $ x\neq z$ . I believe it to be $ =0$ as that would make my problem self-consistent.

## How exactly do I use RawDigger to evaluate signal-to-noise?

I have a trial copy of RawDigger installed, and I understand that for my purposes I should shoot the same subject at different apertures to see if the SNR decreases at faster settings. But how exactly do I read the screen in RawDigger to evaluate the results? I see various acronyms and numeric values in the attached screenshot, but they are meaningless to me. (Note, the photo is just an example; I know it’s not the right kind of image to use for this.)

## Performance management in Agile teams. How to evaluate cross functioning teams

With the clear roles of Scrum members and the self-management Development team, how to evaluate individual performance?

Who is the person responsible for evaluating and promoting/demoting team members?

What are the processes to collect continuous feedback and build this up to appraisal?

How frequent should the appraisal be performed, after each sprint or annually?

## Evaluate $ \lim\limits_{n \to \infty}\sum\limits_{k=2}^{n} \frac{1}{\sqrt[k]{n^k+n+1}+1} $

$ $ \lim_{n \to \infty}\sum_{k=2}^{n} \frac{1}{\sqrt[k]{n^k+n+1}+1} $ $

I expect the squeeze theorem helps us solving this but I can’t find the inequality.

The result should be $ 1$ .

## How to fix rules which unable to evaluate action?

I have created two rules to act on some events related to commerce products.

**The first** is to act on reference node delete event, to remove the product upon node delete.

**the second** is to delete the node upon expiration event using node_expire

When running the cron to make expired event to be happen no actions executed except if I disabled the first rule

I have tried rules **components** and **rule sets** as that two rules have conditions and actions in common But nothing changed.

**Edit**: I did some debugging and found that warning and error messages

[warning]WD rules: Unable to load commerce_product with id “102”

WD rules: Unable to evaluate action entity_fetch.

WD rules: Unable to get variable entity_fetched, it is not defined.

[error]WD rules: Unable to evaluate action entity_delete.

## How to evaluate the UX and improve the Conversion Rate?

Are there any methods to evaluate the strengths and weaknesses of a competitor website User experience to understand how it might be contributing to its CRO?

## How to evaluate an expression using the properties of numbers [on hold]

My homework says to evaluate the expression, 7 * 1/7 + 6(15 / 3 – 5) And to name the property used in each step. The first step is obviously to distribute, but I don’t understand the next steps. Can someone help me on this?

## How to evaluate in a formula that uses summatories and product of vectors?

Could someone tell me how to find beta1?

I have the following data:

I don’t know and I don’t find anything related on google

Please help me

**Edit**

I tried

beta1=(n Total[x.y]-(Total[x])(Total[y]))/(n Total[x^2]-(Total[x])^2) but I got an unexpected number

-6.41769 + 0.00120621 Total[5511.93]

Why?
