number of books.
books

Answers

Answer:

35.80

Explanation:

If Hugh bought 3 magazines that would equal 11.85, and 47.65-11.85=35.80.

I hope this helps

Answer:

since m = 3, therefore 3.95m = 3.95×3 = 11.85

this implies that 11.85 +8.95b = 47.65

this means 8.95b = 47.65 - 11.85 = 35.80

therefore b = 35.80 ÷ 8.9 = 4

since b = 4 ,this means Hugh bought 4 books

Replace '''Your solution goes here''' with:

def kelvin_to_celsius(value_kelvin):

This line defines the function

def kelvin_to_celsius(value_kelvin):

This line initializes value_celcius to 0.0

   value_celsius = 0.0

This line calculates the equivalent of value_kelvin

   value_celsius = value_kelvin - 273.15

This returns the equivalent value_celsius

Answers

The answer to this question is option (d) keyword “function”. The keywordfunction” is not a part of the function definition line.

In the function definition line, the keyword “function” is not included. The function definition line consists of two parts one is the function definition header and the second is the function definition body.

The function definition line, also called function declaration statement, contains:

The name of the function Parameter list that receives input arguments and returns output arguments

Whereas, in the function definition body, the code to perform the intended operation is written.

For example,

int sum(num1, num2)            // this is function definition header

{                                                 /* this is function definition body between      

return num1+num2;           curly brackets “{}” */

}

The above function definition line (written in C++), consisting of function definition header and function definition body (enclosed in curly brackets), is explained below:

In function definition line:

“int” is the return type of function“sum” refers to name of the function num1 and num2 represent a parameter list that function receives as input and produces output for it

In the function definition body, the code is written to perform intented operations i.e. sum, where two numbers num1 and num2 are added.

In the whole function definition line, there is no keyword “function” written. Thus, it is the keyword “function” that is not a part of the function definition line.

In the dual-process model of coping with bereavement, coping with loss and engaging in restoration can occur:_________
a. consecutively.
b. only several years after a death.
c. separately.
d. concurrently.

Answers

In the dual-process model of coping with bereavement, coping with loss and engaging in restoration can occur loss-oriented stressors and restoration-oriented stressors.

This model recognises two categories of stressors, loss- and restoration-oriented, as well as a dynamic, oscillating regulatory coping mechanism wherein the grieving person alternately faces and avoids the various grieving responsibilities.

The DPM framework was developed, used, and evaluated by other researchers globally after it was first conceived by Professors Margaret Stroebe and Henk Schut (both researchers educated in Western traditions) in 1999.

The idea of oscillation is essential to the Dual Process Model. Stroebe and Schut claim that active participation in a dynamic process of alternating between loss- and restoration-focused coping is a necessary component of effective grieving. A person who is grieving will alternate between facing their loss and avoiding it.
