thankyou, how would i express this as a compound inequality?

sorry!! range***

th awnswer is this 1/2

actually i just took it and got a 60. 14 c 15 b and colleen is right will post the correct answers as i get them but 1, 5, 8, 12, 16, 17, 19, 20 are wrong. i have to wait until tommorow to retake.
