Leni [432]

Answer:

48.98\%

Step-by-step explanation:

we know that

The probability that it will hit a point in the outer (yellow) ring is equal to divide the area of the yellow ring by the total area of the target

step 1

Find the area of the yellow ring

A=\pi [7^{2} -5^{2}]

A=24\pi\ cm^{2}

step 2

Find the total area of the target

A=\pi [7^{2}]

A=49\pi\ cm^{2}

step 3

Find the probability

24\pi/49\pi=0.4898

Convert to percentage

0.4898*100=48.98\%

I am having difficulties solving this problem someone pls help.
igor_vitrenko [27]

Answer:

Each time, the x is being multiplied by -3 to result in the output.

So for every x input, multiply by -3.

For the y output for 15, you would divide by -3 to find the input x

For example, when 7 is the input, multiply by -3, and the output y would result in -21.
