A large school district claims that 80% of the children are from low-income families. 200 children from the district are chosen to participate in a community project. Of the 200 only 74% are from low-income families. The children were supposed to be randomly selected. Do you think they really were?

70,000 + 6,000 + 800 + 30

step-by-step explanation:

54.864 meters

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.

i think da answer is

d.square root of 3
