Tyreek pitches for investors. They agree to each invest $25,000 and value tyreek's company at $200,000. How much of the company will tyreek still own after the investment?.
The 50% of the company will tyreek still own after the investment, according to the given question.
What do you mean by investment pitches?
A brief outline of your business plan that piques the curiosity of potential investors should be included in your investment pitch presentation. Because your product is only one component of your business strategy, it shouldn't only be a pitch for your product.
According to data in the given question,
We have the information:
The total value of Tyreek's company = $200,000
Contributed amount of the four investors = $25,000 * 4 = $100,000
Assume P is the percentage of the company which Tyreek will still own after the investment.
\(P=\frac{Total amount contributed by the four investors }{Value of Tyreek's company} \\P=\frac{100,000}{200,000}\\ P=0.5 or 50%\)
Therefore, the 50% of the company will tyreek still own after the investment, according to the given question.

The general law of addition for probabilities says P(A or B) = P(A) P(B). A - True. B - False.
The statement "P(A or B) = P(A) + P(B)" is False.
The correct statement is "P(A or B) = P(A) + P(B) - P(A and B)," which is known as the general law of addition for probabilities. This law takes into account the possibility of events A and B overlapping or occurring together.
The general law of addition for probabilities states that the probability of either event A or event B occurring is equal to the sum of their individual probabilities minus the probability of both events occurring simultaneously. This adjustment is necessary to avoid double-counting the probability of the intersection.
Let's consider a simple example. Suppose we have two events: A represents the probability of flipping a coin and getting heads, and B represents the probability of rolling a die and getting a 6. The probability of getting heads on a fair coin is 0.5 (P(A) = 0.5), and the probability of rolling a 6 on a fair die is 1/6 (P(B) = 1/6). If we assume that these events are independent, meaning the outcome of one does not affect the outcome of the other, then the probability of getting heads or rolling a 6 would be P(A or B) = P(A) + P(B) - P(A and B) = 0.5 + 1/6 - 0 = 7/12.
In summary, the general law of addition for probabilities states that when calculating the probability of two events occurring together or separately, we must account for the possibility of both events happening simultaneously by subtracting the probability of their intersection from the sum of their individual probabilities.

Select the correct answer in each of the following
Answer:
A, A and A
Step-by-step explanation:
Given
y = ax² + bx + c ( a ≠ 0 )
• If a > 0 then vertex is minimum
• If a < 0 then vertex is maximum
The graph here is a maximum, thus a < 0 → A
--------------------------------------------------------------------
The value of c is the y- intercept of the graph ( when x = 0 )
Since the y- intercept is below the x- axis then c < 0 → A
--------------------------------------------------------------------
The solutions to the equation are where the graph crosses the x- axis ( y = 0 )
Since the graph crosses the x- axis to the left of the y- axis, then
both solutions are negative → A
Suppose that x and y vary inversely, and x = 12 when y = 8 . Write the function that models the inverse variation.
Answer:
\(y=\frac{96}{x}\)
Step-by-step explanation:
So when x and y, vary inversely, it means that the product of x and y will remain constant such that: \(xy=c\). This means that the function can be defined as \(y=\frac{c}{x}\) by dividing both sides by x. In this case x=12, and y=8, this means the constant is equal to 12 * 8 which is 96. So we have the equation: \(xy = 96\), which can be defined as \(y=\frac{96}{x}\)

Answer:
15/8 - 6/8= 9/8
Step-by-step explanation:
We get \(\frac{3}{4}\) when we subtract \(\frac{4.5}{4}\) from \(\frac{7.5}{4}\).
What is subtraction?
Subtraction is a operation of taking the difference of two numbers.
According to the given question
We have a number line in which two numbers are indicated.
The one just after \(\frac{4}{4}\) and the another one is after \(\frac{7}{4}\).
So the number after \(\frac{4}{4}\) is \(\frac{4.5}{4}\) and the number after \(\frac{7}{4}\) is \(\frac{7.5}{4}\)
so, \(\frac{7.5}{4} -\frac{4.5}{4} =\frac{3}{4}\)
Hence, we get \(\frac{3}{4}\) when we subtract \(\frac{4.5}{4}\) from \(\frac{7.5}{4}\).

explain, using theorems 4, 5, 7, and 9, why the function is continuous at every number in its domain. state the domain. 33
Since f(x) is an increasing function (i.e., its derivative is always positive), it satisfies the conditions of Theorem 9, the Intermediate Value Theorem.
What is a continuous function.?A continuous function is a mathematical function in which arbitrarily small changes in the input result in arbitrarily small changes in the output.
In other words, a function is b if, for every input value in its domain, the output value exists, the limit exists, and the limit equals the function value. It can also be defined as a function whose graph is a single unbroken curve, meaning that there are no abrupt jumps, gaps, or holes.
Using theorems 4, 5, 7, and 9, explain why the function is continuous at every number in its domain and state the domain: f(x) = (3x + 7) / (2x - 5); Domain: R \ {5/2}; Continuous on its domain as it is a quotient of two continuous functions and there are no vertical asymptotes, holes or jumps in the graph.
The domain of f(x) is all real numbers since there are no restrictions on the values of x for which the function is defined.
To prove that f(x) is continuous at every number in its domain, we need to show that it satisfies the conditions of Theorem 4, which states that a function is continuous at a point if and only if the limit of the function exists at that point and is equal to the value of the function at that point.
In this case, we have:
The limit of f(x) as x approaches any number a is given by:
lim(x→a) f(x) = lim(x→a) (2x + 3) = 2a + 3
The value of f(a) at any number a is given by:
f(a) = 2a + 3
Since the limit of f(x) as x approaches a is equal to f(a), we can conclude that f(x) is continuous at every number in its domain, which is all real numbers.
Furthermore, since f(x) is a polynomial, it is continuous everywhere, which means that it satisfies the conditions of Theorems 5 and 7 as well. Finally, since f(x) is an increasing function (i.e., its derivative is always positive), it satisfies the conditions of Theorem 9, the Intermediate Value Theorem.

APH4: Find the 1 st and 2 nd derivatives of \( Q=x^{4} e^{3 x} \)
the first derivative of\(\( Q=x^{4} e^{3x} \) is \( Q' = 4x^{3}e^{3x} + 3x^{4}e^{3x} \)\), and the second derivative is \(\( Q'' = 12x^{2}e^{3x} + 24x^{3}e^{3x} + 9x^{4}e^{3x} \)\).
To find the first and second derivatives of \(\( Q=x^{4} e^{3x} \),\) we will use the product rule and chain rule. Let's start with the first derivative. 1. Use the product rule: \(\[ Q' = (x^{4})' \cdot e^{3x} + x^{4} \cdot (e^{3x})' \]\)
Simplify: \(\[ Q' = 4x^{3} \cdot e^{3x} + x^{4} \cdot 3e^{3x} \] [Q' = 4x^{3}e^{3x} + 3x^{4}e^{3x} \]\)
Now, let's find the second derivative. 2. Use the product rule again:
\(\[ Q'' = (4x^{3}e^{3x})' + (3x^{4}e^{3x})' \]\)
Simplify: \(\[ Q'' = (12x^{2}e^{3x} + 4x^{3} \cdot 3e^{3x}) + (12x^{3}e^{3x} + 3x^{4} \cdot 3e^{3x}) \] \\ Q'' = 12x^{2}e^{3x} + 12x^{3}e^{3x} + 12x^{3}e^{3x} + 9x^{4}e^{3x} \] \\\ Q'' = 12x^{2}e^{3x} + 24x^{3}e^{3x} + 9x^{4}e^{3x} \]\)

Write a polynomial function in standard form with zeros -1,1 , and 0 .
The polynomial function in standard form with zeros -1, 1, and 0 is f(x) = x(x - 1)(x + 1).
To find a polynomial function with the given zeros, we use the zero-product property. The zero-product property states that if a product of factors is equal to zero, then at least one of the factors must be equal to zero.
Since the zeros are -1, 1, and 0, we can write the factors as (x - (-1)), (x - 1), and (x - 0), which simplify to (x + 1), (x - 1), and x, respectively.
To obtain the polynomial function, we multiply the factors:
f(x) = (x + 1)(x - 1)(x)
= x(x^2 - 1)
= x^3 - x
This is the polynomial function in standard form with zeros -1, 1, and 0.

The P(X<115) is equal to c) 0.04. To calculate this probability, we need to standardize the height of 115 cm by subtracting the mean (150 cm) and dividing it by the standard deviation (20 cm). This gives us a standardized score of -2.75.
Next, we can use a standard normal table to find the probability that a standard normal random variable is less than -2.75. The value in the table for this probability is approximately 0.004.
Finally, we multiply this value by 100% to get the answer in terms of percentage. So, the final answer is 0.004 * 100% = 0.04 or 4%.
In summary, P(X < 115) = 0.04 or 4%, which means that 4% of middle school students in this set have a height of less than 115 cm.
