true/false : a.systematic risk can be eliminated through diversification
True. Systematic risk, also known as undiversifiable risk or market risk, refers to risks that affect a large number of assets or the entire market.
Examples of systematic risk include economic downturns, changes in interest rates, and natural disasters. These types of risk cannot be eliminated through diversification because they affect the market as a whole. However, diversification can help to reduce the impact of systematic risk on an investment portfolio by spreading the risk across a variety of assets. This is because diversification allows an investor to hold a variety of assets that are not perfectly correlated, which can help to reduce the overall risk of the portfolio.

Recall that a contiguous subarray is all of the elements in an array between indices
i
and
j
, inclusive (and if
j
we define it to be the empty array). Call a subarray is nearly contiguous if it is contiguous (i.e. contains all elements between indices
i
and
j
for some
i,j
) or if it contains all but one of the elements between
i
and
j
. For example, in the array
[0,1,2,3,4]
, -
[0,2,3]
is nearly contiguous (from 0 to 3 , skipping 1 ), sum is 5 -
[0,1,2,3]
is nearly contiguous (because it is contiguous from 0 to 3 ), sum is 6 . -
[2,4]
is nearly contiguous (from 2 to 4 , skipping 3 ), sum is 6 . - [3] is nearly contiguous (because it is contiguous from 3 to 3 ), sum is 3 . - [] is nearly contiguous (because it is contiguous from 1 to 0 ), sum is 0 . -
[0,2,4]
is not nearly contiguous (because you'd have to remove two elements). The sum of a nearly contiguous subarray is the sum of the included elements. Given int [] A, your task is to return the maximum sum of a nearly contiguous subarray. For example, on input
[10,9,−3,4,−100,−20,15,−5,9]
your algorithm should return 24 (corresponding to
i=
6,j=8
and skipping the
−5
). (a) Define one or more recurrences to solve this problem. (b) Give English descriptions (1-2 sentences each should suffice) for what your recurrences calculate. Be sure to mention what any parameter(s) mean. (c) How do you caclulate your final overall answer (e.g. what parameters input to which of your recurrences do you check). (d) What memoization structure(s) would you use? (e) What would the running time of your algorithm be (you do not have to write the code). Justify in 1-3 sentences.
(a) One possible recurrence to solve this problem is:
Let f(i, j) be the maximum sum of a nearly contiguous subarray ending at index j and starting at index i or before.
Then the recurrence can be written as:
f(i, j) = max(f(i, j-1), f(i, j-2) + A[j])
This recurrence calculates the maximum sum of a nearly contiguous subarray ending at index j and starting at index i or before by considering two possibilities:
The subarray does not include the element at index j. In this case, the maximum sum is the same as the maximum sum ending at index j-1.
The subarray includes the element at index j, but skips the element at index j-1. In this case, the maximum sum is the sum of the elements ending at index j-2 plus the element at index j.
(b) Another possible recurrence to solve this problem is:
Let g(i, j) be the maximum sum of a contiguous subarray ending at index j and starting at index i or before.
Then the recurrence can be written as:
g(i, j) = max(g(i, j-1) + A[j], A[j])
This recurrence calculates the maximum sum of a contiguous subarray ending at index j and starting at index i or before by considering two possibilities:
The maximum sum of the subarray includes the element at index j. In this case, the maximum sum is the sum of the maximum sum ending at index j-1 plus the element at index j.
The maximum sum of the subarray does not include the element at index j. In this case, the maximum sum is simply the element at index j.
(c) To calculate the final overall answer, we can input the values 0 and n-1 into both recurrences, where n is the length of the array A. This will give us the maximum sum of a nearly contiguous subarray that starts at the beginning of the array and ends at the end of the array.
(d) To implement these recurrences using memoization, we can use a two-dimensional array to store the calculated values of f and g. The array can be initialized with values of 0 for all indices, and then we can fill in the values starting from the bottom right corner and working our way towards the top left corner.
(e) The running time of this algorithm would be O(n^2), because we need to calculate the values of f and g for every possible pair of indices i and j. This requires O(n^2) time in the worst case.

Note that where 32 teams qualified for the 2014 World Cup. If the names of the teams were arranged in sorted order (an array), the number of items in the array that binary search would have to examine to find the location of a particular team in the array, in the worst case at most 6 (Option C).
What is an array?An array is a data structure in computer science that consists of a collection of items, each of which is identifiable by at least one array index or key. A mathematical method is used to determine the location of each element from its index tuple in an array.
Because they hold items of the same kind, arrays are categorized as Homogeneous Data Structures. Numbers, strings, boolean values (true and false), characters, objects, and other data can be stored in them. However, once you specify the kind of data your array will contain, all of its components must be of the same type.

A. By renaming the variables
OB. By adding more pause blocks
OC. By placing it in variable blocks
D. By using a for loop
The correct option regarding how the code should be simplified is given as follows:
D. By using a for loop.
How to simplify the code in this problem?The code in this problem displays for instances of a dialogue variable, each with pauses of 1000 ms.
The say command reads an variable to the variable mySprite, and this happens four times, with different variables.
However, instead of having four line codes, each doing basically the same thing(reading a variable to mySprite), a for loop would simplify the code significantly, as the index of the for loop would be used to control which of the dialogue variables would be read to mySprite.
This means that option D gives the correct option as to how to simplify the code sequence.

Which of the following statements describes a limitation of using a computer simulation to model a real-world object or system?(A) Computer simulations can only be built after the real-world object or system has been created.(B) Computer simulations only run on very powerful computers that are not available to the general public.(C) Computer simulations usually make some simplifying assumptions about the real-world object or system being modeled.(D) It is difficult to change input parameters or conditions when using computer simulations.
A major drawback of simulations is that they are not realistic. People may react differently when faced with real-world situations.
What are the limits of computer simulation?
A good simulation model can be very expensive. Simulations are often expensive because they require significant computational time.
Simulation produces a way to evaluate the solution, but not the solution itself.
Will the simulation affect real-world systems?
Simulations can usually be done manually or with a small calculator. The simulation does not interfere with the real system.
Why are there restrictions on computer models?
All models have limitations as they are not representative of all possible scenarios. They use current knowledge and scientific data, which is subject to change, and therefore models based on that knowledge and data.

T F a) Void Functions can use reference parameters.
Function Calls Using Value and Reference Parameter Examples: Void function call using value parameters (can use expression, constant, or variable)
What is void function in C programming?
Except that they do not return a value when the function executes, void functions are constructed and used just like value-returning functions. The term "void" is used by void functions in place of a data type. A void function does a job before returning control to the caller; nevertheless, it does not return a value.Statements that are void functions are independent. When the function return type in computer programming is void, it means the function doesn't return a value. The word void indicates that a pointer is universal when it appears in a pointer declaration.A function called void *function() in the C programming language returns a value that, when dereferenced, is of the type void.Learn more about void function refer to :
