Gaaffii 1

In the set of natural numbers, which one of the following defines a composite number?

  1. A.A number that has only two distinct factors.
  2. B.A number that is divisible by numbers from 2 to 9.
  3. C.A number that has two or more different factors.
  4. D.A number that has three or more different divisors.
Deebii fi ibsa ilaalaa

Deebii: D A number that has three or more different divisors.

Maaliif

A composite number is defined as a natural number greater than 1 that has more than two distinct positive divisors, meaning it must have three or more different divisors.

Gaaffii 2

Which of the following is true about rationalizing the denominator?

  1. A.Only denominators can be multiplied by an irrational number.
  2. B.Only numerators can be rationalized when there is a radical.
  3. C.It is a method of changing the denominator into a rational number.
  4. D.It is a technique of multiplying a given number by an irrational expression.
Deebii fi ibsa ilaalaa

Deebii: C It is a method of changing the denominator into a rational number.

Maaliif

Rationalizing the denominator refers to the algebraic process of multiplying the numerator and denominator by an appropriate radical expression to eliminate any radicals from the denominator, converting it to a rational number.

Gaaffii 6

Which one of the following refers to the definition of similar plane figures?

  1. A.Figures whose corresponding angles have the same ratio.
  2. B.Figures where one is an enlargement of the other.
  3. C.Figures whose ratios of length of corresponding sides are different.
  4. D.Figures that have different shapes but might have same size.
Deebii fi ibsa ilaalaa

Deebii: B Figures where one is an enlargement of the other.

Maaliif

By definition, two plane figures are similar if they have the exact same shape but not necessarily the same size, meaning one is a scaled enlargement (or reduction) of the other.

In △ABC\triangle ABC m(< B) = 90°, with m(< A) = 30° and BC = 11cm, then what is the length of AC‾\overline{AC}?

  1. A.22 cm
  2. B.2233cm\frac{22\sqrt{3}}{3} cm
  3. C.11311\sqrt{3} cm
  4. D.1133cm\frac{11\sqrt{3}}{3} cm
Deebii fi ibsa ilaalaa

Deebii: A 22 cm

Maaliif

Since m(∠B)=90∘m(\angle B) = 90^\circ, the triangle is right-angled with hypotenuse ACAC. Using the sine ratio for ∠A\angle A, we have sin⁡(30∘)=BCAC\sin(30^\circ) = \frac{BC}{AC}, which simplifies to 12=11AC\frac{1}{2} = \frac{11}{AC} and gives AC=22 cmAC = 22\text{ cm}.

Gaaffii 8

Given a circle of diameter 16 cm, a chord of the circle is 6 cm far from the center of the circle. Which of the following is the length of the chord?

  1. A.272\sqrt{7} cm
  2. B.8 cm
  3. C.474\sqrt{7} cm
  4. D.16 cm
Deebii fi ibsa ilaalaa

Deebii: C 474\sqrt{7} cm

Maaliif

Since the diameter is 16 cm16\text{ cm}, the radius is 8 cm8\text{ cm}. Using the Pythagorean theorem, the half-chord length is 82−62=28=27 cm\sqrt{8^2 - 6^2} = \sqrt{28} = 2\sqrt{7}\text{ cm}, making the full chord length 47 cm4\sqrt{7}\text{ cm}.

Gaaffii 10

Let x‾\overline{x} denote the arithmetic mean of a numerical data. If each observation is multiplied by 0.5, which of the following is the new mean?

  1. A.x‾\overline{x}
  2. B.12x‾\frac{1}{2}\overline{x}
  3. C.2x‾2\overline{x}
  4. D.x‾−0.5\overline{x}- 0.5
Deebii fi ibsa ilaalaa

Deebii: B 12x‾\frac{1}{2}\overline{x}

Maaliif

A property of the arithmetic mean is that if every data point in a set is multiplied by a constant factor, the new mean is the original mean multiplied by that same factor. Thus, multiplying by 0.5 results in (1/2)¯x.
