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. Sixty-five wind speed readings gave an average velocity of x = 1075 cm/sec. Based on long-term experience, o can be assumed to be 260 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 (b) Does the confidence interval indicate that the population mean wind speed is such that the sand is always moving at this site? Explain. No. This interval indicates that the population mean wind speed is such that the sand may not always be moving at this site. Yes. This interval indicates that the population mean wind speed is such that the sand may not always be moving at this site. Yes. This interval indicates that the population mean wind speed is such that the sand is always moving at this site. No. This interval indicates that the population mean wind speed is such that the sand is always moving at this site.

#5 Greetings Expert! Can someone answer my algebra question, I tried different methods that my teacher taught and I’m still not understanding.

Jessica says she doesn’t understand the Pythagorean theorem. She put numbers in for a, b, and c in the equation a2 + b2 = c2, but the equation isn’t always true. For example, when she put in a = 2, b = 3, and c = 4, she got 4 + 9 = 16, which isn’t correct. Jessica wants to know why the Pythagorean theorem isn’t working. Write an informative paragraph discussing Jessica’s conundrum. Why does the Pythagorean theorem appear not to be correct? What misunderstanding does Jessica have? Beckmann, Sybilla.

When I put 2+1 or 3 as the answer it said I got the question wrong? Did I perhaps misread your response?

How do I solve and simplify this equation keeping in mind the order of operations? 17 minus 6 times 3 plus 4 times 2 divided by 3

Yu +5 un?+ 5h +4 2.

I need to figure out how to find the term named in the problem.
