Anetwork security specialist records the number of incoming e-mails containing links that six randomly-selected network users receive in a day. numbers are 56, 124, 54, 82, 96, and 56.
(a) state the mode (if one exists).
(b) find the median. show work/explanation.
(c) determine the sample mean. show work
(d) using the sample mean found in part (c), and given that the sample standard deviation of the data set above is 28.3, what percentage of the data set falls within one standard deviation of the mean? show work/explanation. (d) a. 34.2% c. 66.7% b. 68.4% d. 83.3%

where is the image?

step-by-step explanation:

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
