A design change is required in the valve interface circuit of the temperature-control system shown . The new design will have a valve interface input resistance of $10 \mathrm{k} \Omega$. Determine the effect this change has on the temperature-to-voltage conversion circuit.

The Modern Language Association plans a three-day meeting. The program committee requests 15 overhead projectors for the first day, 28 for the second day, and 19 for the third day. Projectors may be rented for a single day for $17, and they may be rented for two consecutive days for$30. How many should be rented for a single day and how many should be rented for two consecutive days to minimize rental costs?

a. use the technology of your choice to determine the range and sample standard deviation of each of the two data sets. b. compare the two data sets by using your results from part (a). Anthropologists are still trying to unravel the mystery of the origins of the Etruscan empire, a highly advanced Italic civilization formed around the eighth century B.C. in central Italy. Were they native to the Italian peninsula or, as many aspects of their civilization suggest, did they migrate from the East by land or sea? The maximum head breadth, in millimeters, of 70 modern Italian male skulls and that of 84 preserved Etruscan male skulls were analyzed to help researchers decide whether the Etruscans were native to Italy. The resulting data can be found on the WeissStats CD. [SOURCE: N. Barnicot and D. Brothwell, “The Evaluation of Metrical Data in the Comparison of Ancient and Modern Bones.” In Medical Biology and Etruscan Origins, G. Wolstenholme and C. O’Connor, eds., Little, Brown & Co., 1959]

The first bridge over the Piscataqua River, built in $1794$, was the longest bridge in the world. The modern bridge, completed in $1971$, is not the world's longest, but it is well known for its elegant symmetric design. The bridge connects Kittery, Maine with Portsmouth, New Hampshire.

Does the Piscataqua River Bridge have any lines of symmetry? If so, make a simple sketch of the bridge and draw all of its lines of symmetry.
