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%.

Answer:

I think its y^-3

Step-by-step explanation:

Since y^-3/y^-2 are both negatives they would swap places to become positive - y^2/y^3

then using rules of exponents you would subtract the exponents witch would be y^-3

At the annual dogs show chantel noticed that there were three more Scottie’s than schnauzers. She also realized that the number
galben [10]
<span>Let us start with the schnauzers, the easiest one to imagine. Let us assume that there were x number of schnauzers. Scottie's are 3 more than schnauzers. So their number is x+3 Wire haired terriers are 5 less than twice the number of schnauzers. So their number is 2x -5 (2x for twice the number of schnauzers) Now add all these numbers. That is x + x+3 + 2x-5 = 4x -2 The total number of dogs, 78, is given in the question Now we know that 4x -2 =78 4x = 78 +2 = 80 Therefore x = 80/4 = 20. So there were 20 schnauzers, 23 Scottie’s and 35 wire haired terriers</span>
