Answer:

Her computer is producing thermal energy, not heat.

Explanation:

Shelly informs her friend that she wants to repair her system because it has generated a lot of heat and therefore is smoking. Her device produces thermal energy but not heat because when she's working continuously and her system's CPU inside any blocked area at that time electricity pass through the CPU and blocked inside then it producing the thermal energy.

Answer:

The program to this question as follows:

Program:

//header file iostream

#include<iostream> //including file for use basic function

//using name space

using namespace std;

//main method

int main() //defining main method

{

   int a[3][3]; //defining two dimension array

   int x,y,sum=0; //defining variables

   cout<<"Enter array elements: "<<endl; //message

   for(x=0;x<3;x++) // for row

   {

       for(y=0;y<3;y++) //for column

       {

          cin>>a[x][y]; //input values from user.

       }

       

   }

   //loop for calculting sum.

   for(x=0;x<3;x++)

   {

       for(y=0;y<3;y++)

       {

       sum=sum+a[x][y];//add all elements

       }

       

   }

   cout<<"Sum: "<<sum; //print sum.

   return 0;

}

Output:

Enter array elements:  

1

2

3

4

5

6

7

8

9

Sum: 45

Explanation:

In the above C++ programming language code first, a header file is included then the main method is declared, inside a main method 2D array that is "a[][]", and an integer variable is defined that are "i, j, and sum". In the next line for loop is used, this loop is used two times that can be described as follows:

  • The first time it is used for inserting elements from user ends.  
  • The second time, it uses the sum variable to add all array elements. and in the last print function that is "cout" is used for print sum variable value.

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)
