The curriculum committee at Larchmont High School wants to offer a new elective course next year. They decide to survey Larchmont's 1500 students to determine which course students would prefer. The choices are History of Art, Robotics, and Money and You. Which of the following survey methods will allow the committee to make a valid conclusion about which course the students at Larchmont prefer?

B

Assign a number to each student, and use a computer program to generate 150 random numbers between 1 and 1500. Ask those students whose numbers are selected.

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
