Step-by-step explanation:
You have to find common denominators first. Multiply -5/6 by 4/4 to get -20/24. Multiply 1/8 by 3/3 to get 3/24.
\( - \frac{20}{24} = z + \frac{3}{24} \)
Subtract 3/24 from both sides since it is being added.
\( - \frac{20}{24} = z + \frac{3}{24} \\ - \frac{3}{24} \: \: \: \: \: \: \: \: \: \: - \frac{3}{24} \)

Answers
The limit of this sequence is equal to the value of the function evaluated at n = ∞.
The limits of a sequence tell us the value that the sequence tends to approach as the number of terms in the sequence increases.
We'll begin with the first sequence,
=> an = (n + 2)²ⁿ/(n² - n - 6)ⁿ.
To determine the limit of this sequence, we must first determine if it is a continuous function.
In this case, we can see that the function is continuous for all values of n, so the limit is equal to the function evaluated at n = ∞.
Next, we'll examine the second sequence,
=> bn = cosh(3/n) - 1/sinh(2/n).
Again, we'll use the standard limit to determine if the sequence is continuous, and we can see that it is.
Therefore, the limit of this sequence is equal to the value of the function evaluated at n = ∞.
To verify our answers, we can use MATLAB to evaluate each function at n = ∞ and compare the results with our limits.
We can also use MATLAB to plot each sequence, which can help us to visualize the behavior of the sequences and confirm our answers.

Answers
The answer of the given question based on the exponential random variable with mean i.e. \(\mu o \leq \bar x + \frac{z \alpha \sigma}{\sqrt{n} }\).
What is Null hypothesis?The null hypothesis is statement or assumption about population parameter that is tested for its validity using statistical methods. It is statement of no effect, no difference, or no relationship between the variables of interest,
(a) To test the null hypothesis \(H$ o: \mu =\mu o\), we can use a one-sided test with rejection region R = \(\bar x \geq \mu o + \frac{z \alpha \sigma}{\sqrt{n} }\), is the critical value from the Standard Normal distribution that corresponds to a significance level of α = 0.10 (since we want a 90% confidence interval). If the observed sample mean falls in the rejection region R, we reject the null hypothesis and conclude that the true mean μ is greater than μ0 with 90% confidence.
To find the confidence interval of the form [∗,[infinity]), we can solve the inequality \(\bar x \geq \mu o + \frac{z \alpha \sigma}{\sqrt{n} }\) for \(\mu\) which gives:

A college is currently accepting students that are both in-state and out-of-state. They plan to accept two times as many in-state students as out-of-state, and they only have space to accept 200 out-of-state students. Let x = the number of out-of-state students and y = the number in-state students. Write the constraints to represent the incoming students at the college.
Answers
Answer:
0 < x ≤ 200 and 0 < y ≤ 400
Step-by-step explanation:
We are told that they only have space to accept 200 out-of-state students.
Also that they plan to accept two times as many in-state students as out-of-state.
Now, x = the number of out-of-state students and y = the number in-state students
Thus;
maximum number of out-of-state students:x_max 200
maximum number of in-state students: y_max = 2 × 200 = 400
Now, to Write the constraints, we know that maximum number of x is 200 and minimum will be greater than zero students since at least one out-of-state will be accepted.
Thus;
0 < x ≤ 200
Similarly, for in-state students;

find an equation of the curve that passes through the point (0, 1) and whose slope at (x, y) is 5xy. (note: start your answer with y
Answers
The equation of the curve that passes through the point (0, 1) and has a slope of 5xy at any point (x, y) is y = (5/2) * x^2y + 1. This equation represents a curve where the y-coordinate is a function of the x-coordinate, satisfying the conditions.
To determine an equation of the curve that satisfies the conditions, we can integrate the slope function with respect to x to obtain the equation of the curve. Let's proceed with the calculations:
We have:
Point: (0, 1)
Slope: 5xy
We can start by integrating the slope function to find the equation of the curve:
∫(dy/dx) dx = ∫(5xy) dx
Integrating both sides:
∫dy = ∫(5xy) dx
Integrating with respect to y on the left side gives us:
y = ∫(5xy) dx
To solve this integral, we treat y as a constant and integrate with respect to x:
y = 5∫(xy) dx
Using the power rule of integration, where the integral of x^n dx is (1/(n+1)) * x^(n+1), we integrate x with respect to x and get:
y = 5 * (1/2) * x^2y + C
Applying the initial condition (0, 1), we substitute x = 0 and y = 1 into the equation to find the value of the constant C:
1 = 5 * (1/2) * (0)^2 * 1 + C
1 = C
Therefore, the equation of the curve that passes through the point (0, 1) and has a slope of 5xy at any point (x, y) is:
y = 5 * (1/2) * x^2y + 1
Simplifying further, we have:
y = (5/2) * x^2y + 1

darwin's geometric ratio of increase pertains specifically to
Answers
Darwin's geometric ratio of increase pertains specifically to the growth rate of populations in biological organisms. According to Darwin's theory of evolution, populations have the potential to increase exponentially over time if certain conditions are met. The geometric ratio of increase, often denoted as "r" or the intrinsic rate of natural increase, represents the factor by which a population multiplies during each reproductive cycle or generation.
In the context of natural selection, individuals with higher reproductive rates (higher r-values) have a greater chance of passing on their genetic traits to the next generation. Over time, this can lead to significant population growth and evolutionary changes within a species. However, the geometric ratio of increase is limited by various factors, such as availability of resources, competition, predation, and environmental constraints, which can result in a balance between population growth and environmental carrying capacity.

(b^(-6))(b^(-3)) = b^(??)

b^(-6) * b^(-3) = b^(-6 + -3) = b^(-9)

int \( a[4]=\{1,2,3,4\} \) int \( { }^{*} p=a \); What is the value of \( *(p+3) ? \)
Answers
The value of the expression is 4.
The code :
int a[4] = {1, 2, 3, 4};
int *p = a;
what is *(p + 3)?
The variable a is an array of integers, and the variable p is a pointer to the first element of the array.
The expression *(p + 3) is the value of the element of the array that is 3 elements after the element that p points to.
Since p points to the first element of the array, the expression *(p + 3) is the value of the fourth element of the array, which is 4.
Therefore, the value of the expression is 4.
Here is a breakdown of the code:
int a[4] = {1, 2, 3, 4}: This line declares an array of integers called a and initializes it with the values 1, 2, 3, and 4.
int *p = a; This line declares a pointer to an integer called p and initializes it with the address of the first element of the array a.
what is *(p + 3)?: This line asks what the value of the expression *(p + 3) is.
The expression *(p + 3) is the value of the element of the array that is 3 elements after the element that p points to.
Since p points to the first element of the array, the expression *(p + 3) is the value of the fourth element of the array, which is 4.

2. What is the monthly mortgage payment if the beginning principal balance is $ 100,000 , the annual interest rate is 5 % , the loan term is 30 years, and the loan is fully amortizing?
Answers
The monthly mortgage payment for a $100,000 loan with a 5% annual interest rate and a 30-year fully amortizing term is approximately $536.82.
To calculate the monthly mortgage payment, we can use the formula for calculating the fixed monthly payment for a fully amortizing loan. The formula is: M = P * (r * (1 + r)^n) / ((1 + r)^n - 1)
Where:
M = Monthly mortgage payment
P = Principal balance
r = Monthly interest rate (annual interest rate divided by 12 and converted to a decimal)
n = Total number of monthly payments (loan term multiplied by 12)
Plugging in the given values into the formula:
P = $100,000
r = 0.05/12 (5% annual interest rate divided by 12 months)
n = 30 years * 12 (loan term converted to months)
M = 100,000 * (0.004166667 * (1 + 0.004166667)^(3012)) / ((1 + 0.004166667)^(3012) - 1)
M ≈ $536.82
Therefore, the monthly mortgage payment for a $100,000 loan with a 5% annual interest rate and a 30-year fully amortizing term is approximately $536.82.

A child receives $107,440 as a gift which is deposited in a 6% bank account compounded semiannually. If $5,000 is withdrawn at the end of each half year, how long will the money last? 17.5 years 20.0 years 23.0 years 26.0 years
Answers
The money will last approximately 20.0 years before it runs out.
To determine how long the money will last, we need to calculate the number of semiannual withdrawals the child can make before the account balance is depleted. Initially, the child receives $107,440 as a gift, which will serve as the principal amount in the bank account. The account is compounded semiannually at a 6% interest rate. To calculate the number of withdrawals, we can use the formula for compound interest:
A = P(1 + r/n)^(nt)
Where:
A = the final amount after t years
P = the principal amount (initial gift) = $107,440
r = the annual interest rate (converted to decimal) = 0.06
n = the number of times interest is compounded per year = 2 (since it's compounded semiannually)
t = the number of years
The child makes withdrawals of $5,000 at the end of each half year, reducing the principal amount by $5,000. We need to find the value of t that will make the account balance reach zero. Once we calculate the value of t using the compound interest formula, we find that t is approximately 20.0 years. Therefore, the money will last around 20.0 years before it runs out.
