For 1.
Positive correlation means if you plot a country's population and land size on a graph. There would be a linear regression line that's sloping upwards.
Since it's a scatterplot, there will be some that fall out of the line, but most of them should be on the line.
It's (A)
For 2.
An outlier is a datapoint that's far, FAR away from the others, so it's (B)
For 3. (A), it's a single line-of-best fit that runs through the middle of the cluster of data points.
They are arranged the way they are because of the QWERTY layout. It was used to slow down how people typed so they wouldn't get the typewriter jammed. Hope this helps. :)
Answer:
In Python:
N = int(input("Positive integer: "))
if N > 0:
flag = False
for i in range(1,N+1):
if i * i == N:
flag = True
break
print(str(flag))
else:
print("Positive integer only")
Explanation:
N = int(input("Positive integer: "))
If the number is positive
if N > 0:
This initializes a boolean variable to false
flag = False
This iterates from 1 to the input integer
for i in range(1,N+1):
This checks if th number is a square of some integer
if i * i == N:
If yes, flag is set to true
flag = True
The loop is exited
break
This prints either true or false, depending on the result of the loop
print(str(flag))
If otherwise, that the number is not positive
<em>else:</em>
<em> print("Positive integer only")</em>
