What is the term for figures used to measures economic performance?

Convert the following numbers. (Please show all steps; no marks will be awarded if no steps are shown) [1.5 x 4 = 6 marks]

katen-ka-za [31]

Answer:

i. 10210212

ii. 100 101 001 in BASE 2

iii. 46.4631

iv. 12.453125

Explanation:

i. Converting to base 10 we get

= 10 x 162 + 13 x 161 + 9 x 160 = 2777

Converting to base 10 we get =

2777/3 = 925 with remainder 2

925/3 = 308 with remainder 1

308/3 = 102 with remainder 2

102/3 = 34 with remainder 0

34/3 = 11 with remainder 1

11/3 = 3 with remainder 2

3/3 = 1 with remainder 0

1/3 = 0 with remainder 1

Hence the Answer is 10210212

ii. = Octal is taken in pair of 3 bits , Writing binary of each number in 3 bits we get = 100 101 001 in BASE 2

iii. = 1 x 52 + 2 x 51 + 3 x 50 + 3 x 5-1 = 38.6 in decimal

Converting to Octal we get

38 /8 = 4 with remainder 6

4 /8 = 0 with remainder 4

.6 x 8 = 4.8

.8 x 8 = 6.4

46.4631

iv. = 1x 81 + 4 x 80 + 3 x 8-1 + 5 x 8-2 = 12.453125

Suppose that you are asked to modify the Stack class to add a new operation max() that returns the current maximum of the stack

Advocard [28]

Answer:

Following are the code to the given points:

Explanation:

For point 8.1:

public String max()//defining a method max

{

String maxVal=null;//defining a string variable that holds a value

for(int x=0;x<n;x++)

{

if(maxVal==null || a[i].compareTo(maxVal)>0)//defining if blok to comare the value

{

maxVal=a[i];//holding value in maxVal variable

}

return maxVal;//return maxVal variable value

}

For point 8.2:

public void push(String item)//defining a method push that accepts item value in a parameter

{

a[n]=item;//defining an array to hold item value

if(n==0 || item.compareTo(maxVals[n-1])>0)//use if to comare item value

{

maxVals[n]=item;//holding item value in maxVals variable

}

else

{

maxVals[n]=maxVals[n-1];//decreasing the maxVals value

}

n++;//incrementing n value

}

public String pop()//defining a method pop

{

return a[--n];//use return value

}

public String max()//defining a method max

{

return maxVals[n-1];//return max value

}

In the first point, the max method is declared that compares the string and returns its max value.
In the second point, the push, pop, and max method are declared that works with their respective names like insert, remove and find max and after that, they return its value.

Write the function setKthDigit(n, k, d) that takes three integers -- n, k, and d -- where n is a possibly-negative int, k is a n

liq [111]

Answer:

Explanation:

Let's do this in Python, first we need to convert the number into string in order to break it into a list of character, then we can replace the kth character with d. Finally we join all characters together, convert it to integer then output it

def setKthDigit(n, k, d):

n_string = str(n)

d_char = str(d)

n_char = [c for c in n_string]

n_char[k] = d_char

new_n_string = ''.join(n_char)

return int(new_n_string)

Linda installed a special pool for the hydrotherapeutic treatment of severe arthritis, as prescribed by her doctor. The cost of

stellarik [79]

Answer:

Linda is entitled to deduction (before any AGI limitations) of $896 in one year of installation of the pool.

Explanation:

Following is explained calculation for deduction (before any AGI limitations) that is Linda entitled to in the year of installation of the pool.

Given that:

Cost of Installing the pool = $22,400

Paid by insurance company = $5,600

So by deducting the price paid by insurance company from total cost the balance becomes:

Balance = $22,400 - $5,600 = $ 16,800

As the pool increased the value of house by $7,840 so we will deduct this amount from balance:

Balance = $ 16,800 - $7,840 = $8,960

As the useful life given for pool is 10 years so we will divide the balance with 10 to obtain the deduction amount for 1 year:

Deduction amount for one year = $8,960/10 = $8,96

Hence $8,96 will be deducted in one year installation.

i hope it will help you!
