Answer:  B) 67%

<u>Step-by-step explanation:</u>

Find the Area of the Bullseye and Middle ring

A = π r²

A (inside) = π(8)² = 64π

Find the Area of the entire Target

A (target) = π (14)² = 196π

Find the Area of the Outer ring

A (outer ring) = A (target) - A(inside)

                      =   196 π    -    64π

                      =    132 π

The last step is to find the probability of landing on the outer ring:

P=\dfrac{success (area\ of\ outer\ ring)}{total\ possible\ outcomes(area\ of\ target)}=\dfrac{132\pi}{196\pi}=0.673=\large\boxed{67\%}

What is the return value of "select".substring(4, 4)?
Romashka-Z-Leto [24]
I'm assuming the syntax here is Javascript:

The str.substring() method takes in two integers - a start index and an end index - and returns all the characters in the specified range from the original string, <em>including</em> the character in the start index and <em>excluding </em>the character in the end index<em />. Javascript's is <em>0-indexed</em>, which means that all of its indices start at 0.

For instance, if we were to use the method on the string "test" and wanted to return the substring "tes", we'd call the following method:

"test".substring(0,3)

This would return everything from the first character, "t", <em>up to but not including</em> the fourth character, "t". The character immediately before the last "t" (index 3), "s" (index 2) would be our last character, and the console should print "tes" as a result.

For your example, "select".substring(4,4) prints out every character starting at index 4 - the fifth character, "c" - <em>up to but not including </em>the character at index 4. We start and stop at the same character, so the method will only return the character "c", and nothing else.
