## Answers:

1- **C**

Set of number that are not composite between \(1\) and \(25: A= {2, 3, 5, 7, 11, 13, 17, 19, 23}\)

\(Probability =\frac{number \space of \space desired \space outcomes}{number \space of \space total \space outcomes}=\frac{9}{25}\)

2- **D **

Check each option provided:

A.\( \frac{(4+5+8+11+12)}{5}=\frac{40}{5}=8\)

B. \(\frac{(1+5+8+11+12)}{5}=\frac{37}{5}=7.4\)

C. \(\frac{(1+4+8+11+12)}{5}=\frac{36}{5}=7.2\)

D. \(\frac{1+4+5+8+12}{5}=\frac{30}{5}=6\)

E. \(\frac{1+4+5+8+11}{5}=\frac{29}{5}=5.8\)

3- **C**

The weight of \(12.2\) meters of this rope is: \(12.2 × 600 g = 7320 g\)

\(1 kg = 1000 g\), therefore, \(7320 g\) \(÷ 1000 = 7.32\) \(kg\)

4- **E**

\(y = 4ab + 3b^3\)

Plug in the values of \(a\) and \(b\) in the equation: \(a = 2\) and \(b = 3\)

\(y = 4 (2) (3) + 3 (3)3 = 24 + 3(27) = 24 + 81 = 105\)

5- **D**

\((g – f)(x) = g(x) – f(x) = (– x^2 – 1 – 2x) – (5 + x)

– x^2 – 1 – 2x – 5 – x = – x^2 – 3x – 6\)

6- **B**

To find the discount, multiply the number by \((100\% –\) rate of discount).

Therefore, for the first discount we get: \((D)\) \((100\% – 20%\))\(=\) \((D)\) \((0.80) = 0.80\) \(D\)

For increase of \(10 \%\): \((0.80 D)\) \((100%\)\( + 10%)\)) \(=\) \((0.80 D) (1.10)\) \(= 0.88 D = 88\%\) of \(D\)

7- **B**

1000 times the number is \(40.5\). Let \(x\) be the number, then:

\(1000x=40.5\)

\(x =\frac{40.5}{1000}=0.0405\)

8- **B**

Let’s review the options provided.

A. \(4\). In \(4\) years, David will be \(46\) and Ava will be \(10. 46\) is not \(4\) times \(10\).

B. \(6\). In \(6\) years, David will be \(48\) and Ava will be \(12. 48\) is \(4\) times \(12\)!

C. \(8\). In \(8\) years, David will be \(80\) and Ava will be \(14. 50\) is not \(4\) times \(14\).

D. \(10\). In \(10\) years, David will be \(52\) and Ava will be \(16. 52\) is not \(4\) times \(16\).

E. \(14\). In \(14\) years, David will be \(56\) and Ava will be \(20. 56\) is not \(4\) times \(20\).

9- **C**

The area of the floor is: \(6 cm × 24 cm = 144 cm\)

The number is tiles needed \(= 144 ÷ 8 = 18\)

10- **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 \(9\).
