The following box shows the exact output of a code segment: Output Berat pelajar 1:60 Berat pelajar 2 : 55 Purata berat pelajar dalam kg ialah:57.5 Based on this output, which code segment would correctly produce it?

print("Output")\nprint("Berat pelajar 1:60")\nprint("Berat pelajar 2 : 55")\nw1 = 60\nw2 = 55\npurata = (w1 + w2) / 2\nprint("Purata berat pelajar dalam kg ialah:" + str(purata))

w1 = 60\nw2 = 55\nprint("Output")\nprint("Berat pelajar 1 :", w1)\nprint("Berat pelajar 2 :", w2)\nprint("Purata berat pelajar dalam kg ialah:", (w1 + w2) / 2)

print("Output")\nw1 = input("Berat pelajar 1:")\nw2 = input("Berat pelajar 2 : ")\nprint("Purata berat pelajar dalam kg ialah:" + (w1 + w2) / 2)

A program displays quiz eligibility for a school prefect selection. It begins with this line: print("Atur cara memaparkan keputusan kuiz kelayakan pengawas.") The partially completed code uses placeholders P, Q, R, and S: markah = 1 while markah != 0: markah = Q(input("Masukkan satu nombor integer : ")) if markah == 0: R elif markah > 49: print("Tahniah, anda layak") S print("Maaf, anda tidak layak") Which statement should replace P to match the program’s on-screen guidance shown in the output box that says to enter 0 to stop?

print('Masukkan nombor SIFAR "0" jika ingin berhenti')

input('Masukkan nombor SIFAR "0" jika ingin berhenti')

markah = 0

print('Masukkan nombor SATU "1" jika ingin berhenti')

40.

In the same partially completed program for displaying quiz eligibility (see code skeleton in the previous question), which built-in should replace Q so numerical input is read correctly for comparisons?

int

float

str

bool

41.

In the same program, when the user enters 0, the program should thank the user before stopping. Which statement should replace R?

print("Terima kasih")

print("Maaf, anda tidak layak")

print("Tahniah, anda layak")

break

42.

In the same program, after checking 'elif markah > 49', the code should ensure that the message 'Maaf, anda tidak layak' is printed for all other nonzero scores. Which keyword should replace S?

else:

if markah < 50:

elif markah <= 49:

continue

The following code segment is intended to find the average body weight of two pupils but contains errors (three circled regions in the image): m1 = float (input ("Masukkan berat (kg) murid 1 :") ) m2 = float ( ("Masukkan berat (kg) murid 1 :") ) purata = m + m / 2 print("Berat badan (kg)") print("Purata berat badan : ", round (purata, 1),"kg") Which correction best fixes the second assignment so the second pupil’s weight is read properly?

m2 = float(input("Masukkan berat (kg) murid 2 :"))

m2 = input(float("Masukkan berat (kg) murid 2 :"))

m2 = int(input("Masukkan berat (kg) murid 1 :"))

m2 = float("Masukkan berat (kg) murid 2 :")

44.

In the same code, which replacement correctly computes the average of the two weights? The faulty line is 'purata = m + m / 2'.

purata = (m1 + m2) / 2

purata = m1 + m2 / 2

purata = (m1 * m2) / 2

purata = m1 / m2

45.

In the same code, the final output should clearly display the rounded average with units. Which corrected print statement best meets this requirement?

print("Purata berat badan (kg):", round(purata, 1))

print("Purata berat badan:", purata, "kg", 1)

print("Purata berat badan (kg)" + round(purata, 1))

print(round(purata, 1))

A formula is provided for the surface area of a sphere: Surface area $=4\pi j$ where $\pi=3.142$ and $j$ is the radius. Based on this formula, which assignment correctly sets the value of the constant for $\pi$ in code?

pi = 3.142

pi = 22/7 exactly

pi = 3.0

pi = "3.142" (a string)

55.

Using the same sphere formula and constants given, which code line best computes the variable luas_sfera (surface area) from the radius variable jejari?

luas_sfera = 4*pi*jejari*jejari

luas_sfera = 2*pi*jejari

luas_sfera = pi*jejari*jejari

luas_sfera = (4/3)*pi*jejari*jejari*jejari

56.

Which print statement correctly displays the computed surface area stored in luas_sfera?
