Answer given in box.
A region in a plane is said to be convex if, for every two points in the region, the line segment joining the two points is completely contained in the region. If a sector of a circle has a central angle with degree measure m >

The color red has been shown to induce greater aggression in people than the color blue. Researchers conducted a study to determine whether such colorinduced aggression could influence the amount that consumers were willing to pay for an identical product in online auction and online negotiation scenarios.
The researchers photographed a single item against each of four background colors: blue, gray, white, and red. Using a computer, each participant in the study viewed the item against exactly one of the four background colors. Half of the participants were told the item was up for auction and were asked to submit their highest bid for the item. The other half of the participants were told to negotiate a price with the seller and were asked to offer the highest amount that they would be willing to pay for the item.
The researchers expected that participants who viewed the red background would typically behave more aggressively than those who viewed the blue background, Among the auction group, the researchers hypothesized that more aggressive participants would submit higher bids as they tried to beat other potential bidders, Among the negotiation group, the researchers hypothesized that more aggressive participants would make lower offers as they tried to compete against the seller to get the best deal.
Which of the following statements most accurately describes the relationship between the study's results and the researchers' hypotheses?

West River Glen is deciding which network architecture should replace its old copper telephone lines. The town will replace 300 miles of Outside Plant (OSP) cable that will serve approximately 2,500 homes.
The first option is to install a Fiber to the Home (FTTH) system architecture that uses fiber-optic cable to transmit signals from the source to each home. The advantages of this architecture include greater bandwidth capabilities, less signal loss, and slightly lower new-cable deployment costs than the second option. Hybrid Fiber-Coax (HFC).
An HFC network integrates fiber-optic cables and devices with coaxial cables.
This will cost the town substantially less money for internal equipment and for customer installations.
However, the coaxial cable does not last as long as fiberoptic cable and will thus need to be replaced more frequently, resulting in higher long-term maintenance expenses.
The town believes that either the FTTH or HFC architectures will be capable of serving the communities' data and television needs for the next 30 years.
According to the information provided, which of the following attributes is an advantage of HFC network architecture as compared with FTTH architecture?
