What is the range for this set of data? 38, 17, 55, 40

38.

Step-by-step explanation:

range is taking the highest number subtracting it by the smallest

the answer is 38

Step-by-step explanation:

you subtract the biggest number with smallest number

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
