Ayomide is reading a recent article with the headline "School lunches make kids overweight." The article cites a study comparing children at two schools. At the school with the lower obesity rate, only a few children eat school lunch. The other school has a greater percentage of obese children, and most of these children eat school lunch. The article doesn't mention that the school with the higher obesity rate is in an area where most people are below the poverty line, nor does it mention that poverty can be a major factor in obesity. What validity is threatened by the potential confound of poverty?

Action Plan Outline: Veterans with Service Dogs Introduction: - Many veterans struggle with mental and physical health issues after and during service. - Likewise, there are many good dogs that sit in shelters due to the low demand for shelter dogs, as well as the rise of breeders. - By offering proper training, many dogs can be used as ESA or even service dogs, lowering the shelter population as we support veterans mental health problems Needs Assessment - Find organizations that would be willing to train these animals to make sure they are properly suited for the job - Need to come up with some sort of assessment to determine what dogs would be fitted for the training, and which dogs - Figure out how and who would be wanting to participate in aid program, and what our specific demographic would be Action Steps - Establish partnership with local training organizations - establish partnership with local VA offices, and other veteran mental health organizations - Create a system the values dogs based on their characteristics - Create a quiz like program that matches dogs to a veteran that fits for both the veteran and the animal - Create social media presents to help spread the words - Create a campaign to help relay information to people who may not have access to the internet - Provide a schedule to make sure connection between the two is beneficial for both parties Evaluation and Monitoring - Provide check-ins for both parties to gather information - Helps provide a peaceful transition for both parties - Provide financial support as well as emotional ones Challenges - Finding specific companies that will help provide accessible training specific to veterans' needs - Continuing financial support so that it is not a burden on veterans

Find the probability of getting 1 or fewer girls in 8 births. 0.0352 (Type an integer or a decimal. Do not round.) c. Which probability is relevant for determining whether 1 is a significantly low number of girls in 8 births: the result from part (a) or part (b)? A. Since the probability of getting 0 girls is less likely than getting 1 girl, the result from part (a) is the relevant probability. B. Since the probability of getting more than 1 girl is the complement of the result from part (b), this is the relevant probability. C. Since getting 0 girls is an even lower number of girls than getting 1 girl, the result from part (b) is the relevant probability. D. Since the probability of getting 1 girl is the result from part (a), this is the relevant probability. d. Is 1 a significantly low number of girls in 8 births? Why or why not? Use 0.05 as the threshold for a significant event. A. Yes, since the appropriate probability is less than 0.05, it is a significantly low number. B. No, since the appropriate probability is greater than 0.05, it is not a significantly low number. C. No, since the appropriate probability is less than 0.05, it is not a significantly low number. D.

To demonstrate springs in a two-dimensional lattice, you build the apparatus shown below that is composed of 8 parallel chains of springs, with each chain containing 2 identical low-mass springs in series. At the top and bottom, the springs are attached to a lightweight rod. A mass of 10 kg is attached to the bottom rod. Relaxed, the distance d from the bottom to the top of the apparatus is 0.12 m . (The top of the apparatus is attached to the ceiling in the lab which is not shown.) Each of the 16 springs has a stiffness of 48 N / m. If you support the bottom of the apparatus at rest and if d=0.503 m, what is the magnitude of the force by your hand on the apparatus? Fhand = i N

The passage below discusses some of the steps of an engineering-design challenge. Select the part of the passage that describes constraints. Hint: Constraints are factors that limit the possible solutions. a prototype of a water filter Maura and Tony are working on a project for the upcoming science fair. Their plan is to design a water filter using only a water bottle and natural materials found in or near a local stream. They make a crude filter by combining rocks and sand in the water bottle. Maura and Tony then pour stream water through their filter and analyze this filtered water with a microscope. They find that while the filter removed dirt and pieces of plants, it did not remove all of the bacteria. For their next model, they add a layer of silt to their filter.
