Answer:

7

Step-by-step explanation:

First, plug-in f(-3) into t in the function:

f(-3)=-2(-3) +1

Second, multiply -2 and -3 to get 6:

f(-3)=-2(-3)+1⇒f(-3)=6+1

Third, add 6 and 1 to get your answer:

f(-3)= 6+1⇒f(-3)=7

The probability of “landing” in the shaded region to the nearest hundredth is equal to 0.79 or 79.0%.

<h3>How to determine the probability?</h3>

First of all, we would determine the area of the given geometric shapes.

For the square, we have:

Mathematically, the area of a square can be calculated by using this formula;

Area = x²

Area = 50²

Area = 2500 ft².

For the circle, we have:

Mathematically, the area of a circle can be calculated by using this formula;

Area = πd²/4

Area = (3.142 × 50²)/4

Area = 1,963.75 ft².

Now, we can determine the probability as follows:

Probability = 1963.75/2500

Probability = 0.79 or 79.0%.

<h3>When the side length is 40 ft.</h3>

Area = x²

Area = 40²

Area = 1600 ft².

For the circle, we have:

Area = πd²/4

Area = (3.142 × 40²)/4

Area = 1256.8 ft².

Probability = 1256.8/1600

Probability = 0.79 or 79.0%.
