An archery target is shown. the radius of region x is 2 inches. and the radius of the entire target is 4 inches. if an arrow hits the target at random what is the probability that it hits the yellow region x. round to the nearest percent. a.50% b.25% c.75% d.83%

  B.25%

Step-by-step explanation:

We know that the area of a circle is given by ;-

, where r is the radius of the circle.

Given: The radius of the X region = 2 inches

Then, the area of the X region will be :

The radius of the entire target region = 4 inches

Then, the area of the entire target region will be :

Now, the probability that it hits the yellow region X is given by ;-

In percent, the probability that it hits the yellow region X

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!
