Hi, For part B it says its incorrect, can you please explain me and how the right drawing? Thank you :)

Any phd experts there??? Question 34. In the course material you have been introduced to multiple charging for electrospray spectra. Each peak in the spectrum below can be used to provide a measure of the mass of this protein, you can work out the charge associated with each peak, and measures can be averaged to find the overall mass. Use simultaneous equations to find the charge associated with each peak in the spectra below, which will allow you to calculate the average mass of each species. Include an estimate of the error associated with this measure. Graph for Intrpt. Below is samples see calculation etc

Rank the following correlation coefficients (r) in order of their strength from strongest to weakest. a. .21 b. -.67 c. .53 d. -.01 e. .78

Find the answer please.

Please help me with this. I will immediately give you a thumb up. Thank you so much!  briefly describe the main idea of the variational principal and how it is used in the variational method?
