Correct average
= {(30 × 168) – 182 + 172 – 150 + 160} / 30
= {5040 – 182 + 172 – 150 + 160} / 30
= {5040 – 182 + 172 – 150 + 160} / 30
= (5040 – 182 + 172 – 150 + 160) / 30
= 5040 – 182 + 172 = 5030 → 5030 – 150 + 160 = 5040
Correct average = 5040 / 30 = 168 cm
Determine the value of k such that the points A(2,3), B(4,k), and C(6,-3) lie on the same straight line.
(20.98 ÷ 2.91) + (15.12 – 5.96) = ?
60.22 of 349.98% + 419.99 ÷ 14.18 = ?
?% of 1200.22 + 319.82 = 3.99 × 295.64
(11.11 × 31.98) + 14.15% of 749.99 = ? + 124.34
(15.99)2 + 219.98% of 20.01 = ?2 × 75.01%
(804/65) ÷ (11/798) × (129/131) = ?
75.01 + 344.923 - 179.93 = ?3 of (√678 + 3.89)
? + 157.99 – 101.01 = 25.01 × 5.98
