Answer:

D) use SQL or graphical tools to query the database            

Explanation:

To query the database using SQL or graphical tools will help Howie to retrieve bulk of records from the database according to his requirements and it will help to understand and work with the data in a better way than using the data in raw form.

SQL is a language of database used to manipulate and manage the data in the relational database and to query the database.

It is an easy and faster way to query using SQL or graphical tools because no coding is required here.

Different graphical tools are used to present the data in the database in a way that can be easily understood by a person. Different interfaces are provided to visualize the database tables or schema diagrammatically e.g in the form of graphs etc. Different views of the database can be provided to different users according to their requirement and what information they required to be presented.

Lasso: R example

To run Lasso Regression you can re-use the glmnet() function, but with the alpha parameter set to 1.

# Perform 10-fold cross-validation to select lambda --------------------------- lambdas_to_try <- 10^seq(-3, 5, length.out = 100) # Setting alpha = 1 implements lasso regression lasso_cv <- cv.glmnet(X, y, alpha = 1, lambda = lambdas_to_try, standardize = TRUE, nfolds = 10) # Plot cross-validation results plot(lasso_cv)

Best cross-validated lambda lambda_cv <- lasso_cv$lambda.min # Fit final model, get its sum of squared residuals and multiple R-squared model_cv <- glmnet(X, y, alpha = 1, lambda = lambda_cv, standardize = TRUE) y_hat_cv <- predict(model_cv, X) ssr_cv <- t(y - y_hat_cv) %*% (y - y_hat_cv) rsq_lasso_cv <- cor(y, y_hat_cv)^2 # See how increasing lambda shrinks the coefficients -------------------------- # Each line shows coefficients for one variables, for different lambdas. # The higher the lambda, the more the coefficients are shrinked towards zero. res <- glmnet(X, y, alpha = 1, lambda = lambdas_to_try, standardize = FALSE) plot(res, xvar = "lambda") legend("bottomright", lwd = 1, col = 1:6, legend = colnames(X), cex = .7)

A shop will give discount of 10% if the cost of purchased quantity is more than 1000. Ask user for quantity suppose, one unit wi
UkoKoshka [18]

Answer:

The program in Python is as follows:

qty = int(input("Quantity: "))

price = 100 * qty

if qty >1000:

    price = (100 - 0.10 * 100) * qty

print("Cost: "+str(price))

Explanation:

This prompts the user for the quantity

qty = int(input("Quantity: "))

This calculates the price or cost, without discount

price = 100 * qty

This checks if the quantity is greater than 1000

if qty >1000:

If yes, this calculates the price or cost, after discount

    price = (100 - 0.10 * 100) * qty

This prints the calculated cost

print("Cost: "+str(price))
