The port of south louisiana, located along 54 miles of the mississippi river between new orleans and baton rouge, is the largest bulk cargo port in the world. the u. s. army corps of engineers reports that the port handles a mean of 4.5 million tons of cargo per week (usa today, september 25, 2012). assume that the number of tons of cargo handled per week is normally distributed with a standard deviation of .82 million tons. a. what is the probability that the port handles less than 5 million tons of cargo per week? b. what is the probability that the port handles 3 or more million tons of cargo per week? c. what is the probability that the port handles between 3 million and 4 million tons of cargo per week? d. assume that 85% of the time the port can handle the weekly cargo volume without extending operating hours. what is the number of tons of cargo per week that will require the port to extend its operating hours?

definitely a. the others have almost all data points on one side of the line.

just pick what you think i need more time let me know if this

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.
