· d. Zero (A fundamental property of the mean)
33. The average of the first five prime numbers (2, 3, 5, 7, 11) =
· b. 5.6
· 2+3+5+7+115=285=5.6\frac{2+3+5+7+11}{5} = \frac{28}{5} = 5.652+3+5+7+11=528=5.6
34. Simplify 23×322^3 \times 3^223×32 =
· b. 72
· 23=8,32=9,8×9=722^3 = 8, 3^2 = 9, 8 \times 9 = 7223=8,32=9,8×9=72
35. The sides of a triangle are in the ratio 3:4:5. If the perimeter is 24 cm, what is the length of the longest side?
· c. 10 cm
· 3x+4x+5x=24⇒x=23x + 4x + 5x = 24 \Rightarrow x = 23x+4x+5x=24⇒x=2
· Longest side =5x=10= 5x = 10=5x=10
36. What is the average of the numbers: 0, 0, 4, 10, 5, and 7?
· 0+0+4+10+5+76=266=4.33\frac{0+0+4+10+5+7}{6} = \frac{26}{6} = 4.3360+0+4+10+5+7=626=4.33
