Answer:
C
Explanation:
If you look at the picture, you will see why it is C. It says D, but the multiple choices are differently ordered and it is kind of differently worded.
But in conclusion, the answer is C.
He should enter the test results from each week into a spreadsheet and create a line graph.
Line graphs are best for recording progress.
Answer:
To check if the year comes under each 100th year, lets check if the remainder when dividing with 100 is 0 or not.
Similarly check for 400th year and multiple 0f 4. The following C program describes the function.
#include<stdio.h>
#include<stdbool.h>
bool is_leap_year(int year);
void main()
{
int y;
bool b;
printf("Enter the year in yyyy format: e.g. 1999 \n");
scanf("%d", &y); // taking the input year in yyyy format.
b= is_leap_year(y); //calling the function and returning the output to b
if(b==true)
{
printf("Thae given year is a leap year \n");
}
else
{
printf("The given year is not a leap year \n");
}
}
bool is_leap_year(int year)
{
if(year%100==0) //every 100th year
{
if(year%400==0) //every 400th year
{
return true;
}
else
{
return false;
}
}
if(year%4==0) //is a multiple of 4
{
return true;
}
else
{
return false;
}
}

Answer:
computer operation often required using mechanical switches and wires
the hardware was bulky and expensive
Explanation:
Early computing were much slower and bulkier when compared to current standards of computing.
They had smaller memory capacity, required mechanical wires and switched, were large and typically occupied a medium sized room, they also required human input all the time to keep the machines running.
