There should be one more equation.   Anyways   2y = 2x - 8   y = x - 4   This is a straight line equation with slope = 1 and y intercept = -4   :)

# How many ways are there to form a committee with 6 members if it must have strictly more women than men? (answer)

In other word how many ways 2 men can be chosend from a group of 8 and and 4 women from a group of 16   8P2 x 16P4 = 8 factorial / (8-2)factorial       x      16factorial/(16-4)factorial   => 8x7x6x5x4x3x2x1/6x5x4x3x2x1    ...

# Find the value of the permutation (answer)

9P3 = 9 factorial/(9-3) factorial = (9x8x7x6x5x4x3x2x1)/(6x5x4x3x2x1) = 9x8x7 = 504   :)

# Find the value of the combination (answer)

8C2 = 8 factorial/((8-2)factorial x 2factorial) = 8x7x6x5x4x3x2x1/(6x5x4x3x2x1)(2x1) = 56/2 = 28   :)

# What is the ratio of indexes of refraction when light passes from quartz (1.54) to water (1.33) (answer)

Refraction index of quartz with respect to water = 1.54/1.33 = 1.16   :)

Wave speed = frequecy x wavelength   Frequency = wave speed/wavelength   1. In an open tube antinodes are located at the ends of open tube. Minimum number of waves that can fit in an open tube with minimum number of nodes and antinodes is λ/2. Next higher number of wavelengths...

y= (2x-5)2 - 3(2x-5) -4   => 4x2 +25 - 20x - 6x + 15 -4 = 4x2 -26x + 36   => 4x2 -18x -8x +36 = 2x(2x-9) -4(2x-9) = (2x-4)(2x-9)   :)

# given 2Na + Cl2 = 2NaCl, what mass of NaCl should be produced from 13.4 L of Cl2? (answer)

22.4 l of all elements at stp = 1 gram mole of element   13.4 l of chlorine = 22.4/13.4 gram mole   As per equation 1 gram mole of chlorine produces 2 gram mole of NaCl   22.4/13.4 gram mole of chlorine will produce 2x22.4/13.4 gram mole of NaCl   1...

# hgt above lvl ground of the stairs is 1.5 meters. max slope wheelchair can climb is 1:12 (1/12). has to be within building code (answer)

Start with a right angled triangle. Adjacent side = 12, opposite side = 1 is given to you.   1.5 meters given to you is opposite side. Adjacent side you can calculate. Since the slope must be same  1/12 = 1.5/x   x = 12 times 1.5 = 18   That means...

# Find the average and show all work (answer)

Rate of change of deaths = change of deaths/chnage of time = (33963-43510)/(2009-2005) = -9547/4   => -2386.75 deaths/yr :)

# Physics Questions Over Ballistic Pendulum (answer)
