Gaaffii 1

Which one of the following is a discrete variable?

  1. A.The temperature of an object.
  2. B.The speed of a moving object.
  3. C.Profit earned by a company.
  4. D.Number of road accidents in Ethiopia.
Deebii fi ibsa ilaalaa

Deebii: D Number of road accidents in Ethiopia.

Maaliif

A discrete variable is one that can take on a countable number of values. The number of road accidents in Ethiopia is a countable quantity, unlike temperature, speed, or profit which are continuous variables.

Gaaffii 2

The frequency distribution table of a grouped data X is given as shown below. | X | 10 – 14 | 15 – 19 | 20 – 24 | 25 – 29 | | --- | --- | --- | --- | --- | | Frequency | 2 | 3 | 5 | 4 | Which one of the following is true about this data?

  1. A.The upper class boundary of the 3ʳᵈ class is 24
  2. B.The class mark of the 2ⁿᵈ class is 17
  3. C.The class mid-point of the 3ʳᵈ class is 22.5
  4. D.The lower class limit of the 4ᵗʰ class is 24.5
Deebii fi ibsa ilaalaa

Deebii: B The class mark of the 2ⁿᵈ class is 17

Maaliif

The class mark is the midpoint of a class interval. For the second class (15 – 19), the class mark is calculated as (15 + 19) / 2 = 17.

Gaaffii 3

What is the range of the function ff given by f(x)=∣x−12∣+3f(x) = \left|x - \frac{1}{2}\right| + 3?

  1. A.[3,∞)[3, \infty)
  2. B.[12,∞)\left[\frac{1}{2}, \infty\right)
  3. C.[−12,∞)\left[-\frac{1}{2}, \infty\right)
  4. D.[−3,∞)[-3, \infty)
Deebii fi ibsa ilaalaa

Deebii: A [3,∞)[3, \infty)

Maaliif

The absolute value term |x - 1/2| is always non-negative (greater than or equal to 0). Adding 3 means that the range of the function is [3, infinity).

Gaaffii 4

Let A and B be two sets and ff be a function from A in to B (f:A→Bf: A \rightarrow B). In order to say ff is an on-to function which one of the following conditions should be fulfilled?

  1. A.If each element x in A is the pre-image of at least one element y in B under ff, then ff is onto function.
  2. B.If any two elements in B are the images of exactly one element of A, then ff is onto function.
  3. C.If you can find two distinct elements in A that are the pre-image of exactly one elements of B, then ff cannot be onto function.
  4. D.If you can find an element y in B that is not an image of any one of the elements of A, then ff is not onto function.
Deebii fi ibsa ilaalaa

Deebii: D If you can find an element y in B that is not an image of any one of the elements of A, then ff is not onto function.

Maaliif

A function f from A to B is onto (surjective) if every element in B has at least one pre-image in A. Therefore, if there is even one element in B with no pre-image, f cannot be onto.

Gaaffii 5

For a given ellipse, what do you call the ratio of the distance between the two foci to the length of the major axis?

  1. A.Eccentricity
  2. B.Latus rectum
  3. C.Directrix
  4. D.Length of minor axis
Deebii fi ibsa ilaalaa

Deebii: A Eccentricity

Maaliif

By definition, the eccentricity (e) of an ellipse is the ratio of the distance between the two foci (2c) to the length of the major axis (2a), which simplifies to c/a.

Gaaffii 6

Which one is the standard form of the equation of the parabola with vertex (−2,3)(-2, 3) and focus (2,3)(2, 3)?

  1. A.(x+2)2=16(y−3)(x + 2)^2 = 16(y - 3)
  2. B.(x+2)2=−16(y−3)(x + 2)^2 = -16(y - 3)
  3. C.(y−3)2=16(x+2)(y - 3)^2 = 16(x + 2)
  4. D.(y−3)2=−16(x+2)(y - 3)^2 = -16(x + 2)
Deebii fi ibsa ilaalaa

Deebii: C (y−3)2=16(x+2)(y - 3)^2 = 16(x + 2)

Maaliif

The vertex is (h, k) = (-2, 3) and the focus is (h + p, k) = (2, 3), which yields p = 4. Since the axis is horizontal, the standard equation is (y - k)^2 = 4p(x - h), which gives (y - 3)^2 = 16(x + 2).
