Look at the rectangle and the square:
a rectangle pqrs and square lmno are drawn side by side. the length sr of the rectangle is labeled as 12 inches, and the width qr is labeled as 6 inches. the side lm of the square is labeled as 6 inches.
sam says that the length of diagonal sq is two times the length of diagonal om.
is sam correct? justify your answer and show all your work. your work should state the theorem you used to find the lengths of the diagonals.

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
