The time for students to complete a standardized placement exam given to college freshman has a normal distribution with a mean of 62 minutes and a standard deviation of 8 minutes. if students are given one hour to complete the exam, what the proportion of students who will complete the exam?

i did it myself and i got 4.2 (b) hope its right

step-by-step explanation:

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950

this is false ^.^ lol
