Answer:
Hello! I hope I am correct! :)
Step-by-step explanation:
Let’s first calculate the black circle & the white space.
Since there is more white space than the black circle, we already know that the white space will have more probability.
These are the steps you need to do, in order to so love this problem:
1. Find the area of both, the white space and the black circle.
2. Divide both of them by the area of the square.
3. Do all these steps to find the probability/hitting.
Part A:
Black circle: ( π *1^2) / ( π 5^2) = 1/25 = .04 or 3.14% chance.
So we can tell it’s close to zero.
Part B: 1 - .04 = 0.96 or 97%
This is close to one.
(Remember I am not saying the exact, it’s a estimate)
Brainliest would be appreciated!
Hope this helps! :)

Answer:
24 years
Step-by-step explanation:
We are told that the model of number of deers is;
y = 0.75x² + 10.5x + 1300
Where;
y represents number of deers
x represents number of years
Now, we want to find how many years it will take to get to 2000 deers.
Thus;
2000 = 0.75x² + 10.5x + 1300
0.75x² + 10.5x + 1300 - 2000 = 0
0.75x² + 10.5x - 700 = 0
Using quadratic formula, we have;
x = [-b ± √(b² - 4ac)]/2a
x = [-10.5 ± √(10.5²- (4*0.75*-700)]/(2*0.75)
x = [-10.5 ± √(110.25 + 2100)]/(1.5)
x = [-10.5 ± √2210.25]/(1.5)
x ≈ -38 or 24
Number of years can't be negative, so we will take the positive value.
So, x = 24 years
A / B
= 80 / 8
= 10
Therefore the answer is 10
Answer:
Sin theta = 12/13
Step-by-step explanation:
From the question;
Cot theta = 5/12
Kindly recall;
Cot theta = 1/ tan theta
Hence, tan theta = 12/5
Mathematically
tan theta= opposite/adjacent
to get hypotenuse, we will use Pythagoras’ theorem which states that the square of the hypotenuse equals sum of the squares of the two other sides
let hypotenuse be h
h^2 = 12^2 + 5^2
h^2 = 144 + 25
h^2 = 169
h = √169
h = 13
But sine theta = opposite/ hypotenuse = 12/13
4x^2-25= (2x)^2-5^2=(2x-5)(2x+5)
Used: a^2-b^2=(a+b)(a-b)
