Answer and Explanation:
Using Javascript:
function mean(nums){
var array_numbers= new array(nums);
var meanofNums= array_numbers.reduce()/array_numbers.length;
Console.log(meanofNums);
}
Function Std(nums){
var OurArray= new Array(nums);
var meanOfnums= mean(nums);
var i;
for(i=0; i<=OurArray.length; i++){
OurArray[i]= OurArray[i]-meanOfnums*OurArray[i]-meanOfnums;
}
var al_stdOfnums= OurArray.reduce()/OurArray.length;
var stdOfnums= Math. sqrt(al_stdOfnums);
Console.log(stdOfnums);
}
function meanStdDev (nums){
mean(nums);
Std(nums);
}
/*From the code above, we have defined functions and used them in the last function definition meanStdDev (nums), making for code reusability. In defining the functions, we have followed the formulas for calculating mean and standard deviations and implemented in that order. Notice how we used a for loop in std(nums) function definition to iterate through the elements of the array nums, squaring each value and reassigning a new value for each element(using index value) in the array. We then added these values in array using reduce method, dividing by array length and square rooting the value using the math object method sqrt().*/
Answer:
The correct answer to this question is "true".
Explanation:
In a layered operating system, all the layers defined individually and communicate with each other when required. It is also easier to create, manage and update the system. If we change in one layer. The Changement has done in only a specific layer it does not affect any other layers. In this operating system, there are 6 layers.
In the monolithic system. It works on the kernel space. That increases the size of the operating system and kernel. It is different than the microkernel system. In the monolithic system, there are 3 layers.
If we assign any work to both, So the 6 layers will take more time to do that work. when that 3 layers take less time to do that work.
that's way layered operating performance is slower than the monolithic system.
Answer:
a. The cell tower forwards the call to the wireless provider's Mobile Telephone Switching Office
Explanation:
When a cell phone user begins to make a call, it is picked up by the cell tower located in the cell in which the cell phone is located and that belongs to the user's wireless provider. The next step in this process is that the cell tower forwards the call to the wireless provider's Mobile Telephone Switching Office.
