Find the probability that a randomly selected point within the circle falls in the red shaded area (square). Round to the neares

t tenth of a percent.​

Fantom [35]3 years ago

Answer:

probability of selecting the square is 63.7% approximately

Step-by-step explanation:

First of all, the probability of the point of choice is within the red square can be obtained with this formula

probability = expected outcome / total number of possible outcomes

In this case, we are not dealing with discrete values which can be counted. instead, we are dealing with areas.

We are to go about this problem by finding the area of the internal square and dividing it by the area of the circle.

Area of the square

Area of the square = l^2

where length = 4\sqrt{2}

Area = (4\sqrt{2}) ^2 = 32cm^2

Area of the circle

Area of the circle = \pi r^2

area of circle =\pi \times 4^2 =50.26cm^2

Probablity of selecting the square =

32/50.26 = 0.6366

To express this as a percentage, we multiply our answer by 100.

This will give us 0.6366 X 100 = 63.7% approximately

Della by tree seedling that was 2 1/4 feet tall during the first year it grew 1 1/6 ft after two years it was 5 ft tall how much
jasenka [17]
<h2>Greetings!</h2>

Answer:

\frac{19}{12} feet

Step-by-step explanation:

First, we need to find the height after one year:

2.25 + 1 1/6 = \frac{41}{12}

Now to find the amount in the second year, we can subtract the above amount from 5:

5 - \frac{41}{12} = \frac{19}{12}

So in the second year it grew \frac{19}{12} feet


<h2>Hope this helps!</h2>

The ratio of the side adjacent am acute angle and the hypotenuse. Adjacent/hypotenuse
diamong [38]

Answer:  The answer is cosine of that acute angle.


Step-by-step explanation:  We are to find the ratio of the adjacent side of an acute angle to the hypotenuse.

In the attached figure, we draw a right-angled triangle ABC, where ∠ABC is a right angle, and ∠ACB is an acute angle.

Now, side adjacent to ∠ACB is BC, which is the base with respect to this particular angle, and AC is the hypotenuse.

Now, the ratio is given by

\dfrac{\textup{adjacent side}}{\textup{hypotenuse}}=\dfrac{BC}{AC}=\dfrac{\textup{base}}{\textup{hypotenuse}}=\cos\textup{ of angle }ACB.

Thus, the ratio is cosine of the acute angle.
