According to a 2008 study published by the afl-cio, 78% of union workers had jobs with employer health coverage compared to 51% of nonunion workers. in 2009, the employee benefit research institute cited data from large samples that suggested that 80% of union workers had health coverage compared to 56% of nonunion workers. let’s suppose the 2009 data came from random samples of 3,000 union workers and 5,000 nonunion workers. compute the mean of the sampling distribution of differences in the proportions insured.

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0

the answer is c 150

step-by-step explanation:

3 3 6, because in every triangle the longer side is always shorter than the sum of the other two

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.
