What would the theoretical variance (square of the standard deviation) of the following random values be? rand(Normal(80, 10), 200)

Answers

Answer 1

The theoretical variance of the random values is 100

How to determine the theoretical variance?

The distribution is given as:

rand(Normal(80, 10), 200)

The syntax of the distribution is:

rand(Normal(Mean, Standard deviation), Sample size)

This means that:

Standard deviation = 10

Square both sides

Variance = 100

Hence, the theoretical variance of the random values is 100

ii) Explain how space and time overheads arise from use of paging, and how the
Translation Lookaside Buffer (TLB) mitigates the time overheads.

Answers

Answer:

A translation lookaside buffer (TLB) is a memory cache that is used to reduce the time taken to access a user memory location.[1] It is a part of the chip's memory-management unit (MMU). The TLB stores the recent translations of virtual memory to physical memory and can be called an address-translation cache. A TLB may reside between the CPU and the CPU cache, between CPU cache and the main memory or between the different levels of the multi-level cache. The majority of desktop, laptop, and server processors include one or more TLBS in the memory-management hardware, and it is nearly always present in any processor that utilizes paged or segmented virtual memory.

Space and time overheads arise from use of paging, and how the Translation Lookaside Buffer (TLB) mitigates the time overheads contains the most recent jvm to memory address translations.

What is Translation Lookaside Buffer?

A computer cache called a translation lookaside buffer (TLB) is employed to speed up the process of accessing memory locations. t is a component of the program memory on the semiconductor. Here between the CPU and also the CPU cache, here between PC and the primary storage, or among several layers of the multi-level cache are possible locations for a TLB.

Given a list of numbers, find the correct function to find the sum of the squares of only the positive elements.


sqsum1
sqsum2
sqsum3
sqsum4
sqsum5

Answers

Answer:

sqsum4

Explanation:

So to raise a number to a power in python, you can use the ** operation, which is usually confused with the ^, which is an operation, but it is not for raising numbers to a power. It is the xor bit operation, which if you don't know at the moment, it's fine, since it's not necessary for this. each of these lists uses a generation comprehension which is generally defined as: (x for x in object if condition) with the if condition being optional, but in this case it's necessary. If it's a bit confusing, you can define a generator using a function so it's a bit more spread out:

def generator(object):

   for x in object:

       if condition:

           yield x

Although in this instance were going to be performing some operation on x, which in this case is squaring it. So let's just look at the two functions that use the **, since they should be the only options that will be correct.

sqsum1(nums):

   This function does square x, except it uses incorrect syntax. The condition should come after the for loop. Python likely wont tell you this, because it may think you're trying to do something else. You can do one line if statements like this: a if condition else b, which will return a if the condition is true, and b if it isn't. So it may think that you're trying to do this one line if statement, and say that you're missing an else. The function could even implement in this way: x**2 if x > 0 else 0 for x in nums. This way if the x is negative it counts as 0, or in other words isn't counted towards the sum. But without this fix, the function will raise a syntax error

sqsum4(nums):

   This will square each number in x only if the current element "x" is greater than 0, or in other words positive. And then it returns the sum. So this function returns the expected output
