Carl is trying to determine the length of segment mn using the pythagorean theorem. step 1: find the vertex of a possible right triangle. v(4, 1) step 2: find the leg lengths of the right triangle. nv = 7, mv = 5 step 3: substitute the values into the pythagorean theorem. 7 squared + 5 squared = c2 step 4: solve for c. 7 squared + 5 squared = c2 49 + 25 = c2 74 = c2 square root of 74 = c which best describes the accuracy of carl’s solution? carl’s work and answer are both entirely correct. carl’s answer is correct, but he incorrectly labeled the leg lengths in step 2. carl’s work and answer are incorrect. he choose a vertex, v, that does not make a right triangle with mn. carl’s work and answer are incorrect. he substituted and solved incorrectly.

B) Carl's answer is correct but he incorrectly labeled the leg lengths in step 2.

Step-by-step explanation:

I just took the test on edg

introduction, methodology, results, discussion

step-by-step explanation:

an observational study is one which consists of actual observation to record data and then analyse the data.

there are a number of factors that should be analyzed before starting an observational study.

the main four factors are:

i) introduction:   this should be analysed to check whether the purpose of the study is correctly established and the data recorded are appropriate for the study

methodology:   the method of collecting the data, such as whether randomly selected, and whether sample size matches with the population to be studied, whether questions asked are easy to answer by common men, etc.

results: then results such as summary of data with comments should be studied thoroughly

discussion:   the last is the discussion, this can be either by management people or persons who are all interested , etc.

it would more likely be bald eagle because its has more in the box so about 75%.
