Agigantic warehouse stores approximately 50 million empty aluminum beer and soda cans. recently, a fire occurred at the warehouse. the smoke from the fire contaminated many of the cans with blackspot, rendering them unusable. a statistician was hired by the insurance company to estimate p, the true proportion of cans in the warehouse that were contaminated by the fire. how many aluminum cans should be randomly sampled to estimate p to within 0.08 with 95% confidence?

this is not the answer this is just a question. is this middle school math?

step-by-step explanation:

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0

57.09 minus 7.0435 equals

step-by-step explanation:

just subtrach them both and u get the answer of 50.0465

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.
