R - 17.1 = -4.8

Mathematics
1 answer:
denis-greek [22]3 years ago
7 0

<u><em>Answer: r=12.3 *The answer must have a  positive sign or decimal point.*</em></u>

Explanation:

First, you had to do is add 17.1 from both sides of an equation.

r-17.1+17.1=-4.8+17.1

And then, simplify by equation.

17.1+-4.8=12.3

You can also add by the numbers.

12.3+4.8=17.1

r=12.3

Hope this helps!

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)
