The times that college students spend studying per week have a distribution skewed to the right with a mean of 7.5 hours and a standard deviation of 2.6 hours. Find the probability that the mean time spent studying per week for a random sample of 65 college students would be a. between 7.1 and 7.6 hours.

b. less than 8.4 hours

you get texts and minutes, so why not

statement #3: proof- ang is congruent to ang ecd : angles are congruent.  

step-by-step explanation:

1: the missing angles in statement #3  

a.) acb  

reason- the reason why the answer is acb is because angle ecd and angle acb are both the same size *that's what the word congruent means this is really simple.  

2: the missing word in reason #3  

c.) vertical  

reason- the reason why the answer is vertical is because the angles in that diagram on figure 2 is slanted, which is vertical, and the e and a both lay on vertical lines. along with the other's, but e and a are the 2 main points you want to focus on. and c is kind of like your starting point, because c is for both angles, not just one.  

i hope that was and understanding.
