4. Fourteen musical acts have asked to perform at Springfield High School's winter talent show. Eight of them play acoustic music and 6 play electric music. Unfortunately, there is only room on the program for 10 acts.
a. How many different groups of 10 acts can be selected to play in the winter show?
b. If the 10 musical acts are randomly selected, what is the probability that all of the electric acts get to
play in the show?

according to egenuity the answer is

step-by-step explanation:

d. 344.22

answer: the answer is e

step-by-step explanation:

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.
