Answer:
The minimum number of assignment statements needed is 5
Step-by-step explanation:
To write the algorithm, we apply the strategy of interchanging the values of variables in the assignment statements.
Assume "tmp" is the new variable, let assign tmp to w
The algorithm is:
Procedure exchange (w,x,y,z: integers)
tmp := w
w := x
x := y
y := z
z := tmp
return (w,x,y,z)
end
From the algorithm, it is obvious that there will be a minimum of 5 assignment statements needed.
Answer:
5 x 8 = 40
Step-by-step explanation:
the formula for the area of a parallelogram is a = bh. Its the same as a square or rectangle. So you just have to multiply the lenght (5) and width (8) which equals 40.
Hope this help have a great day!
Answer:
Let's simplify step-by-step.
0.8x+19−0.7x
=0.8x+19+−0.7x
Combine Like Terms:
=0.8x+19+−0.7x
=(0.8x+−0.7x)+(19)
=0.1x+19
Answer:
=0.1x+19

1) The MST will have 3 connections to Mal, more than any other node.
2) The sum of weights is 250 +3*300 +500 = 1650.
.. (You can rule out 1560 as a choice because no weight ends in 10 or 60. This is simply test-taking savvy, not math.)
