The probability of hitting it once is the ratio of the bullseye area to the whole target.
So 144/484=.2975
For it to happen twice in a row, would be this squared which is .088=.09 or 9%

Answer: Third option is correct.

Step-by-step explanation:

Since we have given that

Radius of area of bulls eye = 12 cm

So, Area of bulls eye would be

\pi r^2\\\\=\pi (12)^2\\\\=144\pi

Similarly, radius of complete circle = 12+5+5=22 in.

So, Area of circle is given by

\pi r^2\\\\=\pi (22)^2\\\\=484\pi

We need to find the probability that a shooter will hit the bulls eye two shots in a row is given by

\dfrac{144}{484}\times \dfrac{144}{484}\\\\=0.0885\\\\=8.85\%\\\\\approx 9\%

Hence, third option is correct.

Solving Rational equations. LCD method. Show work. Image attached.
Dmitry [639]

Answer:

b=1

Step-by-step explanation:

The given rational equation is

\frac{2b-5}{b-2} -2=\frac{3}{b+2}

The Least Common Denominator is (b+2)(b-2).

Multiply each term in the equation by the LCD.

(b+2)(b-2)\times \frac{2b-5}{b-2} -(b+2)(b-2)\times2=(b+2)(b-2)\times\frac{3}{b+2}

Simplify;

(b+2)\times \frac{2b-5}{1} -2(b+2)(b-2)=(b-2)\times\frac{3}{1}

(b+2)(2b-5) -2(b+2)(b-2)=3(b-2)

Expand and group similar terms

2b^2-5b+4b-10 -2(b^2-4)=3b-6

2b^2-5b+4b-10 -2b^2+8=3b-6

-b-2=3b-6

3b+b=-2+6

4b=4

b=1
