Answer:

Probability that point chosen is in large circle but not in shaded region:

P = 84%

Step-by-step explanation:

Given that

r = 2 inches

R = 5 inches

<h3>Area of Small circle (shaded region):</h3>

A=\pi{r}^2\\A=\pi(2)^2\\A=12.56 in^2

<h3>Area of Large circle:</h3><h3>A=\pi{r}^2\\A=\pi(5)^2\\A=78.5in^2</h3><h3>Probability of Point being chosen is inside shaded region:</h3><h3>P=\frac{12.56}{78.5}\\P=0.16\\P=16\%</h3><h3>Probability of Point being chosen is NOT inside shaded region:</h3>

P = 100% - 16%

P = 84%

PLZ HELP BASIC c ALGEBRA BRAINLIEST TO QUICKEST ANSWER

The standard linear equation is:
mx + b = y

So here's what we know:
68x + b = 124
80x + b = 172

If we invert the first equation, we can get rid of b and thus isolate x:
80x + b = 172
-68x - b = -124
12x = 48
x = 12

Now that we have x, we can solve for b:
68 * 4 + b = 124
272 + b = 124
b = -148

Let's check our answer:
80*4 - 148 = 172
320 - 148 = 172
172 = 172

So our final equation is:
4 * Temp - 148 = chirps
