Re: Unilag 2015/2016 Admission by Umartins1(m): 5:42pm On Jun 12, 2015 |
@harbeemx,,,,,, This is the answer u provided and my judgement 1. The mean of seven numbers is 10. If six of the numbers are 2, 4, 8, 14, 16 and 18. Find the mode. Your answer : 2+4+8+14+16+18+x/7=10:x=8 mode=8 correct 2. The radius of a circle is increasing at the rate of 0.02cm/s. Find the rate at which the area is increasing when the radius of the circle is 7cm. Your answer 2pi r*0.02 2*3.142*7*0.02=0.879 wrong Correction: A = pi r2 dA/dR= 2pi r dr/dt= 0.02 dA/dt= dA/dr * dr/dt = 2pi r * 0.02 = 2 * 22/7 * 7 * 0.02 = 44 * 0.02 = 0.88cm2/s 3. In how many ways can a student select 2 subjects from 5 subjects? Your answer 5p2=5!/2!3!=10 wrong Correction: 5C 2 This is how you can get 10. 4. Solve for x and y in equations below: Your answer : X^2-y^2=4 X+y=2 (X+y)(x-y)=4 2(x-y)=4 X-y=2 Put x=2-y Y=0;x=2 correct 5. The angles of a polygon are given by x, 2x, 3x, 4x and 5x respectively. Find the value of x. Your answer: X+2x+3x+4x+5x=15x (2n-4)90 (2*5-4)90 6*90=540 15x=540 X=36 correct 6. Find the distance between the point (4,3) and the intersection of y=2x+4 and y=7-x. Your answer Y=y 2x+4=7-x 3x=3 X=1 Y=6 (1 6) (4 3)(1 6) (1-4)^2+(6-3) ^2=18 correct but put square root. 7. If angle X is 135o, evaluate cos X Your answer : Cos135=sin(180-135)= Sin45=cos45= 1/ root2 wrong Correction: -cos (180-135) -cos45 -1/root 2 . You didn't put minus. 9. The mean of seven numbers is 96. If an eight number is added, the mean becomes 112. Find the eight number. Your answer X/7=96=672 672+x/8=112 672+x =896 X=224 correct 10. A chord of a circle of radius 7cm is 5cm from the centre of the circle. What is the length of the chord? Your answer 7^2-5^2 49-25 24= Root of 24=4.9 4.9*2=9.8 correct 11. A solid metal cube of side 3cm is placed in a rectangular tank of dimensions 3cm, 4cm and 5cm. What volume of water can the tank now hold? Your answer v.of the cube=3^3=27 V.Of tank=3*4*5=60 Total volume=60+27=87cm^3 wrong Correction: you are to subtract. |
