C) 50

Explanation:To find the median of the runs scored:
Data: 60, 15, 120, 50, 48, 4, 56, 100, 80, 8, 15
Step 1: Arrange in ascending order:
4, 8, 15, 15, 48, 50, 56, 60, 80, 100, 120
Step 2: Since there are \( n = 11 \) players (odd number), median is the middle value, which is the \( \frac{n+1}{2} = \frac{12}{2} = 6 \)th term in ascending order.
Step 3: The 6th term in the sorted list is \( 50 \).
Thus, median = \( 50 \).
\( \boxed{50} \)

D) \( \frac{15}{17} \times (2^{0} – 1) \)

Explanation:Evaluate each option:
1) \( \frac{15}{16} – \frac{3}{4} = \frac{15}{16} – \frac{12}{16} = \frac{3}{16} \) (not whole)
2) \( \frac{2}{5} \div 1 = \frac{2}{5} \) (not whole)
3) \( \frac{11}{12} + \left( \frac{1}{2} \times \frac{5}{6} \right)
= \frac{11}{12} + \frac{5}{12} = \frac{16}{12} = \frac{4}{3} \) (not whole)
4) \( \frac{15}{17} \times (2^{0} – 1)
= \frac{15}{17} \times (1 – 1)
= \frac{15}{17} \times 0
= 0 \) (whole number)

A) \( \pi r^{2} h \)

Explanation:Volume of a cylinder
= Base area × Height
= \( \pi r^{2} h \)

B) 8

Explanation:Let's solve step-by-step.
Let the number be \( x \).
Step 1: Multiply by 8: \( 8x \)
Subtract 16 from the product: \( 8x – 16 \)
Step 2: This gives six times the number itself:
8x – 16 = 6x
Step 3: Solve for x:
8x – 6x = 16
2x = 16
x = 8
Step 4: Check:
\( 8 \times 8 = 64 \)
\( 64 – 16 = 48 \)
\( 6 \times 8 = 48 \) ✅
\( \boxed{8} \)

D) right angle

Explanation:Supplementary angles sum to 180°.
Let angle = x
Supplementary angle = \( 180 – x \)
Given:
\( 180 – x = x \)
\( 2x = 180 \Rightarrow x = 90° \)
90° is a right angle.
