## Answers:

1- **B**

Write the numbers in order:

\(4, 5, 8, 9, 13, 15, 18\)

Since we have 7 numbers (7 is odd), then the median is the number in the middle, which is 9.

2- **E**

Surface Area of a cylinder \(= 2πr (r + h)\),

The radius of the cylinder is 8 inches and its height is 12 inches.

Surface Area of a cylinder \(= 2 (π) (8) (8 + 12) = 320 π\)

3-** E**

\(average = \frac{sum of terms}{number of terms}\)

\(18 = \frac{13+15+20+x}{4}\)

\(72 = 48 + x ⇒ x = 24\)

4- **C**

Let \(x\) be the original price.

If the price of the sofa is decreased by \(25\%\) to \(\$420\), then: \(75 \%\) of \(x=420 ⇒ 0.75x=420 ⇒ x=420÷0.75=560\)

5- **E**

Frist, factor the function:

\(x (x+2)(x+3)\)

To find the zeros, \(f(x)\) should be zero.

\(f(x)=x (x+2)(x+3)=0\)

Therefore, the zeros are:

\(x=0\)

\((x+2)=0 ⇒ x= -2\)

\((x+3)=0 ⇒ x= -3\)

6- **C**

Use simple interest formula:

I=prt

(I = interest, p = principal, r = rate, t = time)

\(I=(8,000)(0.045)(5)=1,800\)

7- **E**

\((3.2 × 10^6) × (2.6 × 10^{−5}) = (3.2 × 2.6) × (10^6 × 10^{−5}) = 8.32 × (10^{6 + (−5)} ) = 8.32 × 10^1\)

8- **E**

The formula of the volume of pyramid is:

\(V=\frac{l ×w ×h}{3}\)

\(V=\frac{6×6 ×12}=144 cm^3\)

9- **E**

ince the triangle ABC is reflected over the y-axis, then all values of \(y\)’s of the points don’t change and the sign of all \(x\)’s change.

(remember that when a point is reflected over the y-axis, the value of \(y\) does not change and when a point is reflected over the x-axis, the value of \(x\) does not change).

Therefore:

\((−1,6) \space changes \space to \space (1, 6)\)

\((−2, 5) \space changes \space to \space (2, 5)\)

\((5, 8) \space changes \space to \space (−5, 8)\)

10- **E**

Use Pythagorean theorem:

\(a^2 + b^2 = c^2\)

\(12^2 + 16^2 = x^2\)

\(144 + 256 = x^2\)

\(400 = x^2\)

\(x = 20\)
