The standardized verbal scores of students entering a large university are normally distributed with a mean of 600 and a standard deviation of 80. Find the percent of scores that are: a) between 600 and 760
b) greater than 670
c) less than 360
d) between 440 and 680
e) between 520 and 840
f) greater than 760

Ithink the answer is d

True because the skills you do at work and home are different

The answer is    (d) 7/2======we have    we also  have an integral      notice how function f splits up at x = 0. there's a left piece and a right pieceso we'll need to do the same thing with our integral: split it at x = 0we use a property of integrals that allows us to split up and sum:     notice that for the piecewise function f, the function has the equationf(x) = x when x  ≤ 0. so for the integral  , f(x) = x so it changes into      for the piecewise function f, the function has the equationf(x) = x+1  when x  > 0. for the integral  , we have    therefore, back to our splitted integral:    

Ithink the answer is c hope i
