Answer:

def is_dual( array):

   if len(array) % 2 == 0:

       count = 0

       for i in range(0, len(array)//2, 2):

           if array[i] + array[i+1] == array[0] + array[1]:

               count += 1

       if count == len(array)//2:

           return True

       else:

           return False

Explanation:

The python program defines a function called is_dual that accepts an array parameter and check if the array is dual. If it meets the condition, the function returns true but returns false when the array is not dual.

Why does the position of drawCircle(x, y, r) in the answer choices matter?
Andrei [34K]

Answer:

B and C

Explanation:

xPos and yPos determine the center of the circle, and rad determines the radius of the circle drawn.

It cannot be A because it starts drawing a circle with the center of (4, 1). None of the circles ahve a center at (4, 1). It is B because while it does start at (4, 1), the repeat function adds one to the y and radius. While ti repeats 3 times it ends up drawing all 3 circles. C also works because it starts by drawing the biggest circle and then subtracting the values to make the other two. It cannot be D because in the repeat function it subtracts from the y value and radius too early, it doesn't draw the biggest circle.
