A​ true/false test has questions. A passing grade is ​% or more correct answers. a. What is the probability that a person will guess correctly on one​ true/false question?

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

not sure but it may be b, as i said i'm not sure.

it would be 0.18 because when the other choices are converted they equal those two numbers.   hope this !
