Elizabeth is 5 years old, and she likes to help her mother when it is time for supper. However, her mother is often quick tempered at the end of the day, scolding Elizabeth when she tries to help. Her mother finds she can get things done more quickly if Elizabeth stays out of the way. Based on Erikson’s theory, Elizabeth may develop:

The query “select productid from products where categoryid=1” returns a list of category-1 product IDs. Which of the following allows you to find rows in orderdetails that involve category-1 products?

A data analyst wants to calculate a 3-day moving average of daily sales from a sales table with the following columns:- sale_date (DATE)- amount (DECIMAL)Which of the following SQL queries correctly computes a 3-day moving average of sales using a window function in MySQL?

A data scientist is tasked to query a MySQL table named “invoices” and return the “invoice_id”, “invoice date”, and “order” columns. Which of the following SELECT statements is most suitable?

You want to find the first product sold by each store based on the sale date. Which window function would be most appropriate?

SCENARIO You’re volunteering at a nutrition pop-up for first-year college students. One of the main displays features a “Healthy Smoothie Bowl” with these ingredients: Banana (carbohydrates – sugars & fiber) Peanut butter (fats & proteins) Greek yogurt (proteins & some carbs) Honey drizzle (simple sugars – fructose & glucose) Chia seeds (healthy fats & some protein) You’re asked to help explain why these ingredients give us energy, help us grow, or keep us full—and how their structure matters just as much as what they’re made of! QUESTION/S CHOOSE 2 of the following questions to answer (5pts/question) and provide details (like what we discussed in class) to support your answers. Copy and paste the specific question into your answer box so it is obvious which questions you are choosing! 1) Greek yogurt and peanut butter both contain proteins, which are made of smaller parts called amino acids. Protein structure is like a beaded necklace that folds up. How might the shape of a folded protein affect what it does in the body? 2) Fats have long chains of carbon and hydrogen. How do you think this structure helps them provide more energy than sugars? 3) All these molecules—carbs, proteins, and fats—are made of carbon, hydrogen, and oxygen (and sometimes nitrogen).So why do they do such different things in our bodies? In other words, How does the structure of a molecule affect what it does? 4) Why do simple sugars like those in honey give us quick energy, but fiber from bananas takes longer to digest?

Consider the data Repair. Develop the estimated simple linear regression equation to predict the repair time (y) given the type of repair (x1). x1 = 0 if the type of repair is mechanical and 1 if the repair is electrical. Does the equation developed in part (a) provide a good fit?
