pickupchik [31]

Answer:

The probability is    P(Z) = 0.0064

Step-by-step explanation:

From the question we are told that

  The number of members is  n = 15

Generally the number of ways of selecting two member from the fifteen members is mathematically represented as

       K  =  ^{n}C_2 *  2!

Here C stands for combination hence we will be making use of the combination functionality in our calculator

      K  =  ^{15}C_2 *  2 * 1

=>  K  =  78  *  2 * 1

=>  K  =  156

Gnerally the number of outcome that matches the outcome required by the committee(Which is  reselecting the member who where the chairman and vice chairman of the board ) is   m =  1

Generally the probability of randomly selecting the two members who currently hold the positions of chairman and vice chairman and assigning them to their current positions is mathematically represented as

      P(Z) =  \frac{m}{K}

=>    P(Z) =  \frac{1}{156}

=>    P(Z) =  \frac{1}{156}      

 =>    P(Z) = 0.0064

Is 1/8 - 10(3/4-3/8x)+5/8x equivalent to -1/8(59-35x)
madreJ [45]

Answer:

Yes

Step-by-step explanation:

1/8-10(3/4-3/8x)+5/8x

1/8-(30/4-30/8x)+5/8x

1/8-30/4+30/8x+5/8x

Lcm is 8

1-60+30x+5x/8

-59+35x/8

Factorise

-1/8(59-35x)

So when comparing the two,they are observed to be the same
