Before you begin your proctored assessment, pick up each piece of paper (and/or white board) and show the front and back side to the camera. Make sure to do it slowly enough that any writing will be clearly visible.  Remember that no physical calculators, smart glasses, smart watch or other people or electronic aids are permitted in the testing area. Remove any applicable items before starting. Practice showing your papers now. Get a sheet of paper (it is okay to leave the test area if you need to grab one) and hold it up to the camera. Show both sides and count to at least three slowly. Click OK as your answer choice

Dataset: Urban Rooftop Garden Productivity This dataset contains 1,000 observations representing urban rooftop gardens. The purpose of the dataset is to explore which environmental, physical, and management factors are associated with annual crop yield. roof_area_m2 : Total area of the rooftop garden in square meters. Larger gardens generally have greater potential crop production. (Numerical) sunlight_hours: Average number of hours of direct sunlight the garden receives per day during the growing season. (Numerical) soil_depth_cm : Depth of the growing medium in centimeters. Greater depth can provide plants with more space for roots and better water retention. (Numerical) watering_frequency: Average number of times the garden is watered per week. (Numerical) avg_temperature_c: Average growing-season temperature in degrees Celsius. Extremely low or high temperatures may reduce productivity. (Numerical) fertilizer_kg: Approximate amount of fertilizer applied to the garden during the growing season, measured in kilograms.(Numerical) irrigation_system: Type of irrigation used: Drip, Sprinkler, Manual, or Automated. (Categorical) garden_type: Primary type of crops grown: Vegetable, Herb, Fruit, or Mixed.(Categorical) growing_medium: Primary growing medium used: Soil, Compost Mix, Coco Coir, or Hydroponic. (Categorical) maintenance_level: Overall level of garden maintenance: Low, Medium, or High. (Categorical)    annual_yield_kg (Response variable): Total amount of crops harvested from the rooftop garden during one year, measured in kilograms. (Numerical)

An older adult with significantly reduced renal function is prescribed a medication that is primarily eliminated unchanged by the kidneys. Which prescribing consideration is most appropriate?

Two liquids are mixed in an insulated container. The final temperature is below both initial temperatures. Best explanation:

The figure (not to scale) shows a pV diagram for 1.8 g of helium gas (He) that undergoes the process 1 → 2 → 3. Find the value of V1. The ideal gas constant is R = 8.314 J/mol ∙ K = 0.0821 L ∙ atm/mol ∙ K, and the atomic weight of helium is 4.0 g/mol. 

0.80 kg copper (Cu) at 250°C is dropped into 1.5 kg water at 20°C (insulated). Specific heat cCu=385, cW=4186 J/kg·K. Find final T.

One mole of an ideal gas is held at a constant pressure of 1 atm (=1.013×105 Pa). Find the change in volume (in liters, 1L= 10-3 m3) if the temperature changes by 50°C.

A 2-mol sample of oxygen gas expands slowly and adiabatically from a pressure of 5 atm and a volume of 12.0L to a final volume of 30.0L. Find the change of internal energy.
