Plea asap one base of the trapizoid is three times the lengh of the second base. the height of the trapizoid is 2 in. smaller than the second base. if the area of the trapizoid is 30in^2, find the lengths of the bases and the height of the trapizoid . a student is painting an accent wall in his room where the length of the wall is 3ft^2 more than its width. the wall in his room where the length is 3ft more than its width . the wall has an area of 130ft^2. what are the length and the width, in feet. find two consecutive even integers whose product is 80. (there are two pairs, and only an algebraic solution will be excepted)

Q.1 dr. frank needs to choose 3 students from her advanced biology course to attend a conference in hawaii. the course has 40 students. which of the following methods could dr. frank use to choose a simple, random sample of 3 students? select all that apply. 1 dr. frank could have the students line up from shortest to tallest, then use her birthdate, 2/5/39, to select 3 students from the line (the 2nd student, the 5th student, and the 39th student). 2. dr. frank could upload her class roster into a spreadsheet and use a ranom-number generating function to produce 3 random numbers. the students whose names are located in the rows with these 3 numbers on the spreadsheet would be chosen. 3. dr. frank could choose the students with the 3 highest grades in the class. 4. dr. frank could count to three, then the first students to come to the front of the classroom and grab a golden ticket from her hand would be selected. 5. dr. frank could ask all students to write their name on a card, place all of the cards in a hat, shake the hat, and then pull 3 cards out from the hat. the students whose names appear on those 3 cards will be selected. 6. dr. frank could ask for volunteers to go to the conference, then choose the first 3 students who raise their hands. q2. now, choose one of the methods that you did not select and explain why this method would not result in a simple, random sample:
