There are 10 red marbles and 8 green marbles in a jar. So, the probability that all three marbles taken from the jar are red is 0.147.
Given :
Number of red marbles = 10
Number of green marbles = 8
Probability is the department of mathematics concerning numerical depictions of how likely the event is to happen or how likely it is that suggestion is genuine. The probability of an event could be number between 0 and 1 , where o shows difficulty of the event and 1 shows certainty.
Total number of marbles in a jar = 10 + 8 = 18
Total number of red marbles in a jar = 10
So, the probability that all three marbles taken from the jar are red is:
[tex]= \dfrac{10}{18}\times\dfrac{9}{17}\times\dfrac{8}{16}[/tex]
[tex]= 0.147[/tex]

help me plz it will be on the exam! Pedro and Bobby each own an ant farm. Pedro starts with 100 ants and says his farm is growing exponentially at a rate of 15% per month. Bobby starts with 350 ants and says his farm is steadily decreasing by 5 ants per month.
Assuming both boys are accurate in describing the population of their ant farms, after how many months will they both have approximately the same number of ants?
Final answer:
To find the month when Pedro's exponentially growing ant farm and Bobby's linearly decreasing ant farm have the same number of ants, we set the exponential growth formula equal to the linear decrease formula and solve for the number of months, using graphical or numerical methods.
Explanation:
We need to determine after how many months Pedro's exponentially growing ant farm will have the same number of ants as Bobby's linearly decreasing ant farm.
Let's denote the number of months as m. Pedro's ant farm starts with 100 ants and grows at a rate of 15% per month, so the population at month m is PPedro = 100 × (1 + 0.15)m.
Bobby's ant farm starts with 350 ants and decreases by 5 ants per month, so the population at month m is PBobby = 350 - 5m.
We need to find the month m where PPedro is approximately equal to PBobby. This can be solved by equating and solving the two expressions:
100 × (1 + 0.15)m ≈ 350 - 5m
To solve this, we can use either graphical methods or numerical methods such as iterative approximation, since an exact solution may not be possible through algebraic methods. We are looking for the value of m that makes both sides approximately equal.

The ordered pairs (1, 4), (2, 16), (3, 64), (4, 256), and (5, 1,024) represent a function. what is a rule that represents this function?
Final answer:
The rule that represents the given function with ordered pairs (1, 4), (2, 16), (3, 64), (4, 256), (5, 1,024) is f(x) = 4^(x-1), which is determined by observing the pattern of the ordered pairs.
Explanation:
Identifying the Rule of a Function
The ordered pairs (1, 4), (2, 16), (3, 64), (4, 256), and (5, 1,024) represent a function where each input from the domain is mapped to a unique output in the range. Observing the pattern of the ordered pairs, we can infer a rule that corresponds to this function. Each second element in the pair appears to be an exponentiation of 4 to the power of the first element minus one.
The general rule for this function can be expressed as f(x) = 4^(x-1). We can verify this by plugging in the values from the domain (1 through 5) into the function:
For x = 1, f(1) = 4^(1-1) = 4^0 = 1
For x = 2, f(2) = 4^(2-1) = 4^1 = 4
For x = 3, f(3) = 4^(3-1) = 4^2 = 16
For x = 4, f(4) = 4^(4-1) = 4^3 = 64
For x = 5, f(5) = 4^(5-1) = 4^4 = 256
Therefore, the rule representing this function is f(x) = 4^(x-1).

An angle measures 24° more than the measure of a complementary angle. what is the measure of each angle?
The angle which is 24° more than the measure of its complementary angle is 66°.
What are complementary angles?Two angles whose sum is equivalent to 90 degrees are called complementary angles. Mathematically -
∠x + ∠y = 90°
Assume that the angle which is 24° more than the measure of its complementary angle be [x].
Then, we can write -
x + 24 = 90
x = 90 - 24
x = 66°
Therefore, the angle which is 24° more than the measure of its complementary angle is 66°.

There are 38 pockets on an american roulette wheel: 18 red, 18 black, and 2 green. if you were to randomly spin an american roulette wheel, what is the probability that it would land on a green pocket
The probability of an American roulette wheel landing on a green pocket is 1/19, which is calculated by dividing the number of green pockets by the total number of pockets on the roulette wheel.
Explanation:The student is asking about the probability of a specific outcome in a random event, specifically, the likelihood of landing on a green pocket in an American roulette game. To find this probability, we need to look at the total number of pockets and how many of them are green. With 38 total pockets and 2 being green, the probability that the roulette wheel will land on a green pocket is calculated by the ratio of green pockets to total pockets.
To calculate it: Probability = Number of green pockets / Total number of pockets = 2 / 38 = 1/19
This simple division computes the likelihood of a single spin resulting in a green pocket landing. Importantly, this calculation assumes each pocket has an equal chance of being landed on and that there are no biases in the wheel.
