You are conducting a study on the health of people who have been exposed to radiation and those who have not been exposed to radiation.
Which of these methods of obtaining data should you most likely adopt and why?
OA
an observational study because it involves the pre-existing condition of the subjects
an experimental study because it will give the most accurate results
OB.
OC.
an experimental study because results can be obtained much faster using this technique
D.
a sample survey with only people who were not exposed to radiation because it involves random selection
O E.
a sample survey with only people who were exposed to radiation because it involves random selection

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

10 - 75

step-by-step explanation:

there's nothing attached so it's most likely anything in that range.
