Simplify \(\frac{25 \frac{2}{3} \div 25 \frac{1}{6}}{( \frac{1}{5})^{-\frac{7}{6}} \times ( \frac{1}{5})^{\frac{1}{6}}}\) A. 25 B. \(\frac{1}{5}\) C. 1 D. \(\frac{1}{25}\)
Show Content
Detailed Solution\(\frac{25 \frac{2}{3} \div 25 \frac{1}{6}}{( \frac{1}{5})^{-\frac{7}{6}} \times ( \frac{1}{5})^{\frac{1}{6}}}\) = \(\frac{25^{4 - \frac{1}{6}}}{(\frac{1}{5})^{-7 + \frac{1}{6}}}\)= \(\frac{25^{\frac{1}{2}}}{(\frac{1}{5})^{-1}}\) = \(\frac{(5^2)^{\frac{1}{2}}}{(5^{-1})^{-1}}\) = \(\frac{5}{5}\) = 1 |

Simplify \(\frac{x - 4}{4} - \frac{x - 3}{6}\) A. \(\frac{x - 18}{12}\) B. \(\frac{x - 6}{12}\) C. \(\frac{x - 18}{24}\) D. \(\frac{x - 6}{24}\)
Show Content
Detailed Solution\(\frac{x - 4}{4} - \frac{x - 3}{6}\) = \(\frac{3(x - 4) - 2(x - 3)}{12}\)= \(\frac{3x -12 - 2x + 6}{12}\) = \(\frac{3x - 2x - 12 + 6}{12}\) = \(\frac{x - 6}{12}\) |

Given that y = 1 - \(\frac{2x}{4x - 3}\), find the value of x for which y is undefined A. 3 B. \(\frac{3}{4}\) C. \(\frac{-3}{4}\) D. -3
Show Content
Detailed Solutionfor undefined expression, the denomination is zero 4x - 3 = 04x = 3; x = \(\frac{3}{4}\) |

A fair coin is tossed three times. Find the probability of getting two heads and one tail. A. \(\frac{1}{2}\) B. \(\frac{3}{8}\) C. \(\frac{1}{4}\) D. \(\frac{1}{8}\)
Show Content
Detailed SolutionPr(head) = \(\frac{1}{2}\), Pr(tail) = \(\frac{1}{2}\):Pr(2 heads)= \(\frac{1}{2}\) x \(\frac{1}{2}\) = \(\frac{1}{4}\) Pr(2 heads and tail) 3 times = (\(\frac{1}{4}\) x \(\frac{1}{2}\)) x 3 = \(\frac{3}{8}\) |

If 30% of y is equal to x, what in terms of x, is 30% of 3y? A. \(\frac{x}{9}\) B. \(\frac{x}{3}\) C. x D. 3x
Show Content
Detailed SolutionIf 30% of y = x, then 30% of 3y = 3x |

A baker used 40% of a 50kg bag of flour. If \(\frac{1}{8}\) of the amount used was for the cake, how many kilogram of flour was used for the cake? A. 2\(\frac{1}{2}\) B. 6\(\frac{1}{2}\) C. 15\(\frac{3}{8}\) D. 17\(\frac{1}{2}\)
Show Content
Detailed Solution\(\frac{40}{100} \times 50\)kg = 20kg\(\frac{1}{8}\) of 20kg for cake; \(\frac{1}{8}\) x \(\frac{20}{1}\) = 2\(\frac{1}{2}\)kg |
