Question 9 unsaved the starting salaries of individuals with an mba degree are normally distributed with a mean of $54,000 and a standard deviation of $6,000. what is the probability that a randomly selected individual with an mba degree will get a starting salary of at least $60,000

Unsaved?

Anyway, 60,000 is one standard deviation above the mean. By the 68-95-99.7 rule 68% of the probability is between -1 and +1 standard deviations, so 34% between 0 and 1 sigma so 50%-34%=16% above one sigma.

16%

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
