The statement that describes an aspect of the team's commitment at the end of PI Planning is to maintain predictability with uncommitted objectives.

A program increment (PI) simply means a timebox during which an agile release train helps in delivering incremental value in the form of tested and working systems and software.

A program increment (PI) is usually eight to twelve weeks long. An aspect of the team's commitment at the end of PI Planning is to maintain predictability with uncommitted objectives.

Type two statements that use rand() to print 2 random integers between (and including) 100 and 149. End with a newline. Ex:

rosijanka [135]

Answer:

#include <stdlib.h>

#include <time.h>

#include<iostream.h>

int main(void) {

int seedVal = 0;

seedVal = 4;

srand(seedVal);

/* Solution*/

cout<<rand() % 149 + 100<<endl;

cout<<rand() % 149 + 100<<endl;

return 0;

}

Explanation:

We start with the required include statements to enable use of srand, rand and time functions. I have also added iostream library to use "cout" function.

After that, the seed is initialized using srand(). And then the two rand functions are called with ranges including and between 100 and 149, and printed out.

Replace any alphabetic character with '_' in 2-character string passCode. Ex: If passCode is "9a", output is: 9_

oksian1 [2.3K]

Answer:

if(isalpha(passCode[0]))

{

passCode[0] = '_';

}

if(isalpha(passCode[1]))

{

passCode[1] = '_';

}

Explanation:

The first if statement uses isalpha() function which checks if the character passed in this function is an alphabet. If the character stored in 0-th position (which is the first position whose index is 0) of the variable passCode is an alphabet then it is replaced with the '_'

The next if statement checks if the second character in the passCode variable is an alphabet. This means the function isalpha() checks if the character stored in second position (index 1) of the variable passCode is an alphabet then it is replaced with the '_'

The complete activity with this chunk of code added and the output is attached in a screen shot.

In this problem we consider sending real-time voice from Host A to Host B over a packet-switched network (VoIP). Host A converts

Minchanka [31]

Answer:

The total time elapsed from the time a bit is created (from the original analog signal at Host A) until the bit is decoded (as part of the analog signal at Host B is 25.11 ms

Explanation:

Host A first converts the analog signal to a digital 64kbps stream and then groups it into 56-byte packets. The time taken for this can be calculated as:

time taken 1= $\frac{Packet Size in Bits}{Bit Rate}$

= (56 x 8) bits / 64 x 10³ bits/s

= 7 x 10⁻³s

time taken 1= 7 ms

The transmission rate of the packet from Host A to Host B is 4 Mbps. The time taken to transfer the packets can be calculated as:

time taken 2= (56 x 8) bits / 4 x 10⁶ bits/s

= 1.12 x 10⁻⁴ s

time taken 2= 112 μs

The propagation delay is 18 ms.

To calculate the total time elapsed, we need to add up all the time taken at each individual stage.

$Time_{total}$ = Time taken 1 + Time taken 2 + Propagation Delay

= 7 ms + 112 μs + 18 ms

= 0.025112 s

$Time_{total}$ = 25.11 ms

The hostel in which you plan to spend the night tonight offers very interesting rates, as long as you do not arrive too late. Ho

faust18 [17]

Answer:

Answered below

Explanation:

// Python implementation

incrementAmount = 5

basePrice = 10

price = 0

arrivalHour = int(input("Enter arrival hour 0-12: ")

if arrivalHour < 0 or arrivalHour > 12:

print ("Invalid hour")

if arrivalHour == 0:

price = basePrice

else:

price = arrivalHour * incrementAmount

totalPrice = price + basePrice

if totalPrice > 53:

totalPrice = 53

print ("Your bill is $totalPrice")
