Answer:

\sf \dfrac{203}{4108}

As a decimal = 0.05 (nearest hundredth)

Step-by-step explanation:

\sf Probability \ of \ an \ event \ occurring = \dfrac{Number \ of \ ways \ it \ can \ occur}{Total \ number \ of \ possible \ outcomes}

First pick:

\sf \implies P(pink)=\dfrac{30}{80}

As the case is NOT replaced, second pick:

\sf \implies P(pink)=\dfrac{30-1}{80-1}=\dfrac{29}{79}

As the case is NOT replaced, third pick:

\sf \implies P(pink)=\dfrac{29-1}{79-1}=\dfrac{28}{78}

Therefore,

\sf \implies P(pink \ and \ pink \ and \ pink)=\dfrac{30}{80} \times \dfrac{29}{79} \times \dfrac{28}{78}=\dfrac{203}{4108}

Answer as a decimal = 0.05 (nearest hundredth)

We are to form the combination of 6 objects taken 2 at a time. This can be expressed as 6C2

6C2= \frac{6!}{2!*4!} \\  \\ &#10;= \frac{6*5}{2} \\  \\ &#10;=15

This means, there can be 15 different combinations of 2 members that can sit in the front row.

So, the answer to this question is option A

Answer:

x=−32/5

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

1/2(1/4x−3/5)=1/4(2/5+3/4x)

(1/2)(1/4x)+(1/2)(−3/5)=(1/4)(2/5)+(1/4)(3/4x)(Distribute)(1/2)(1/4x)+(1/2)(−3/5)=(1/4)(2/5)+(1/4)(3/4x)(Distribute)

1/8x+−3/10=1/10+3/16x

1/8x+−3/10=3/16x+1/10

Step 2: Subtract 3/16x from both sides.

1/8x+−3/10−3/16x=3/16x+1/10−3/16x

−1/16x+−3/10=1/10

Step 3: Add 3/10 to both sides.

−1/16x+−3/10+3/10=1/10+3/10

−1/16x=2/5

Step 4: Multiply both sides by 16/(-1).

(16/−1)*(−1/16x)=(16/−1)*(2/5)

x=−3/25
