Find the length of the chord |AB| in the diagram shown below.
A. 4.2 cm B. 4.3 cm C. 3.2 cm D. 3.4 cm Correct Answer: Option D D. 3.4 cm Explanation Length of chord = 2rsin(θ/2) = 2(3)sin(68/2) = 6sin34 = 6×0.559 = 3.354 cm ≊ 3.4 cmIn a class of 50 students, 40 students offered Physics and 30 offered Biology. How many offered both Physics and Biology?
A. 42 B. 20 C. 70 D. 54 Correct Answer: Option B B. 20 Explanation n(Total) = 50 n(Physics) = 40 n(Biology) = 30 Let n(Physics and Biology) = x n(Physics only) = 40 -x n(Biology only) = 30 – x 40 – x + 30 – x + x = 50 70 – x = 50 x =...The table above shows the number of pupils in a class with respect to their ages. If a pie chart is constructed to represent the age, the angle corresponding to 8 years old is
Ages in years 7 8 9 10 11 No. of Pupils 4 13 30 44 9 A. 48.6° B. 56.3° C. 46.8° D. 13° Correct Answer: Option C C. 46.8° Explanation Total number of pupils : 4 + 13 + 30 + 44 + 9 = 100 The number of 8 – year olds = 13 The angle represented by the 8-year olds on...A binary operation ⊗ is defined by m⊗n=mn+m−n on the set of real numbers, for all m, n ∈ R. Find the value of 3 ⊗ (2 ⊗ 4).
A. 6 B. 25 C. 15 D. 18 Correct Answer: Option C C. 15 Explanation m⊗n=mn+m−n 3 ⊗ (2 ⊗ 4) 2 ⊗ 4 = 2(4) + 2 – 4 = 6 3 otimes 6 = 3(6) + 3 – 6 = 15The angle of elevation of the top of a tree from a point on the ground 6cm away from the foot of the tree is 78°. Find the height of the tree correct to the nearest whole number.
A. 148m B. 382m C. 282m D. 248m Correct Answer: Option C Explanation tan78 = h/60 h =60tan78 h= 60×4.705 =282.27m ≊ 282m to the nearest whole number.Products
