Data Analysis Answers :
1)
Correct Answer: C
Explanation:The reduction of 50 is apparent between April and May. Since the measurement is taken at the end of the month, the reduction took place in May.
2)
Correct Answer: A
Explanation: At the end of the second quarter, B is outselling A at 400 to 300 units. B in terms of A is B / A = 400 / 300 = 1.333 or 133%.
3)
Correct Answer: B
Explanation: Probability of red = 1/5, probability of blue = 11/25. Red in terms of blue = 5/25. Adding the two probabilities we get red+blue = 16/25. To make the probability 1, there could be 9 white marbles as (16+9)/25 = 1.
Geometry Answers :
1)
Correct Answer: C
Explanation: The area of the unshaded region is equal to the area of whole object, minus the area of the shaded cube. The are of the whole object is 4 * 6 * 3 = 72, the area of the cube is x^3. The area of the unshaded region is 72 – x^3.
2)
Correct Answer: C
Explanation: The area of the shaded region (a triangle) is PS * SQ / 2.
PS = PR – RS,
PS = 12 – 7.
PS = 5. 5 * 7 / 2 = 17.5.
3)
Correct Answer: E
Explanation: The radius of the circle is 1/2 * the length of TW or pi. The area of the circle = A = pi*r2, so A = pi*pi2 or pi3.
Algebra Answers :
1)
Correct Answer: C
Explanation: Since a*b*c = 1, we know a, b and c are not 0. This means in b*c*d, d must equal 0. If d is 0, c * d must also equal 0.
2)
Correct Answer: A
Explanation: Writing the problem algebraically, 4x + 1 = x – 5. Solving for X we get 3x = -6 or x = -2.
3)
Correct Answer: A
Explanation:An example coordinate between D and E is .75. If .75 is divided by -1/2 = -1.5. The answer will always be less than -1 so to the left of A.
