HELP PLEASE A certain mapping in the xyxyx, y-plane has the following properties:
For the point AAA, the image A'A

′

A, prime is at the same point as AAA.

A point PPP that is not at AAA maps counterclockwise to point P'P

′

P, prime such that m\angle PAP'=\thetam∠PAP

′

=θm, angle, P, A, P, prime, equals, theta.

The lengths of \overline{AP}

AP

start overline, A, P, end overline and \overline{AP'}

AP

′

start overline, A, P, prime, end overline are equal.

A. a translation

B. a reflection

C. a rotation

At wind speeds above 1000 centimeters per second (cm/sec), significant sand-moving events begin to occur. wind speeds below 1000 cm/sec deposit sand and wind speeds above 1000 cm/sec move sand to new locations. the cyclic nature of wind and moving sand determines the shape and location of large dunes. at a test site, the prevailing direction of the wind did not change noticeably. however, the velocity did change. fifty-nine wind speed readings gave an average velocity of x = 1075 cm/sec. based on long-term experience, σ can be assumed to be 245 cm/sec. (a) find a 95% confidence interval for the population mean wind speed at this site. (round your answers to the nearest whole number.) lower limit cm/sec upper limit cm/sec
