College students are often targeted by credit card companies with advertisements. A survey conducted at a university found that 65% of students had opened a new credit card account within the past year.

To answer your question, we need to use basic probability concepts. If 65% of students surveyed had opened a new credit card account within the past year, then the probability that a randomly chosen student has not opened a new credit card account is 1 - 0.65 = 0.35 or 35%.
Now, let's say we want to find the number of students we need to survey before finding one who had not opened a new account in the past year. This is equivalent to finding the number of trials before we get a success (i.e., finding a student who had not opened a new account).
We can use the formula for geometric distribution, which is:
P(X = k) = (1 - p)^(k-1) * p
where X is the number of trials before the first success, p is the probability of success, and k is the number of trials.
In our case, p = 0.35 (the probability of finding a student who had not opened a new account) and we want to find k (the number of trials).
We can set the probability to find a student who had not opened a new account to be greater than 0.5 (i.e., 50%) to ensure a high chance of success. So, we have:
P(X >= k) = 0.5
(1 - 0.35)^(k-1) * 0.35 = 0.5
Taking the logarithm of both sides and solving for k, we get:
k = log(0.5) / log(0.65)
k ≈ 3
Therefore, we would expect to survey about 3 students before finding one who had not opened a new credit card account in the past year.

In conclusion, college students are often targeted by credit card companies with advertisements. A survey conducted at a university found that 65% of students had opened a new credit card account within the past year. This statistic suggests that credit cards are popular among college students, who may be looking for ways to finance their education and living expenses. However, it is also important to note that credit card debt can be a major burden for students, especially if they are unable to make timely payments or manage their finances effectively. The probability analysis conducted in this answer shows that we would expect to survey only about 3 students before finding one who had not opened a new credit card account in the past year. This highlights the need for financial education and literacy programs for college students, to help them make informed decisions about credit card use and avoid potential debt problems.

To find if functions, f1(x) = ex and f2(x) = sin(x), are orthogonal functions  on the interval [/4, 5/4], evaluate the integral of their product. If integral evaluates to zero, functions are orthogonal; else not orthogonal.

To check if f1(x) = ex and f2(x) = sin(x) are orthogonal on the interval [/4, 5/4], we need to calculate the integral of their product over that interval:

∫[4,5/4] f1(x) * f2(x) dx.

To determine if the integral is zero, we need to evaluate it. We can use numerical methods or software to approximate the value of the integral.

If the result of the integral is zero (or very close to zero within a certain tolerance), then f1(x) and f2(x) are orthogonal on the interval [/4, 5/4].  Otherwise, if the integral is nonzero, the functions are not orthogonal on the given interval.

The value of expressions of the logarithms are:

ln(AB) = x + y

ln(A)/ln(B) = x - y and

AB = e^(x+y)

To write the expressions in terms of x and y, follow these steps:

1) ln(AB)=
Using the properties of logarithms, ln(AB) can be written as ln(A) + ln(B). Now substitute x and y:
ln(AB) = x + y

2) ln(A)/ln(B)=
Using the properties of logarithms, ln(A)/ln(B) can be written as ln(A) - ln(B). Now substitute x and y:
ln(A)/ln(B) = x - y

3) AB=
To find AB in terms of x and y, first write A and B in terms of e (since x=ln(A) and y=ln(B)):
\(A = e^x\)
\(B = e^y\)
Now multiply A and B

\(AB = (e^x)(e^y)\)
Using the properties of exponents, \((e^x)(e^y)\) can be written as \(AB = e^{x+y}\) . So,
\(AB= e^{x+y}\)

Answer:

\(\left \{ {{x=4} \atop {y=1}} \right.\)

Step-by-step explanation:

Rearrange like terms to the same side of the equation:

\(\left \{ {{4x+2y=18} \atop {x=3+y}} \right.\)

Substitute into one of the equations:

\(4(3+y)+2y=18\)

Apply the Distributive Property:

\(12+4y+2y=18\)

Combine like terms:

\(12+6y=18\)

Rearrange variables to the left side of the equation:

\(6y=18-12\)

Calculate the sum or difference:

\(6y=6\)

Divide both sides of the equation by the coefficient of variable:

\(y=\frac{6}{6}\)

Cross out the common factor:

\(y=1\)

Substitute into one of the equations:

\(x=3+1\)

Answer:

y = 4

x= -6

Step-by-step explanation:

Substitution; so pretty much finding one equation and substituting it into the second

Let's find the equation of the top one... we'll find X (you can find either x or y though)

2x - 3y = -24

We'll add 3y to both sides

2x = 3y - 24

Dividing by 2 on both sides

x = (3y-24)/2... Simplifying it to x = 1.5y - 12

Let's put it into x + 6y = 18. Since we found X

1.5y - 12 + 6y = 18

Let's add 12

1.5y + 6y = 30

Combining like terms

7.5y = 30

Lastly, we'll divide by 7.5

y = 4

So now that we finally found Y, we can use either equation to solve for X. I'll do both to show both equations end up with the same X

2x-3y =-24

2x-3(4)=-24

2x-12=-24

2x=-12

x=-6

---------

x+6y=18

x+6(4)=18

x+24=18

x=-6

based on the given information, we can definitively conclude that PV- is closer to 0 than to 1. The option (b) "PV- is closer to 0 than to 1" is the correct answer.

The present value (PV) represents the current value of a future cash flow or investment. If PV is approximately 1, it means that the value of the future cash flow or investment is close to its full value in the present.

When we subtract a value from PV to get PV-, the resulting value will be smaller than PV. Since PV is approximately 1, it implies that PV- is closer to 0 than to 1. This conclusion holds because subtracting a value from 1 will always yield a smaller value.

For example, if PV is exactly 1 and we subtract 0.5 from it, the resulting PV- will be 0.5, which is closer to 0 than to 1.

x²+√2x+3  and x²+√2x+6  are expressions that are not polynomial. (Option a and Option b)

An expression that consists of variables, constants, and exponents that is combined using mathematical operations like addition, subtraction, multiplication, and division is referred to as a polynomial (No division operation by a variable).

A polynomial function is one that uses only non-negative integer powers or positive number coefficients of such a variables in such an expression like the quadratic function, cubic equation, and so on.

For the algebraic expression to be called a  polynomial, the exponents in the algebraic expression should be non-negative integers. Also if an algebraic expression has a radical in it then it can not be called a polynomial.

a) x²+√2x+3. This expression is not a polynomial as the polynomial expression does not contain any radicals. √2 here is a radical root.

      ⇒   Hence, option a is not a polynomial expression.

b) x²+√2x+6.This expression is also not a polynomial expression as it has a radical √2 present in the expression.

      ⇒   Hence, option b is not a polynomial expression.

c) x³+3x²-3. This expression can be termed as a polynomial expression since all of the variables have positive integer exponents.

     ⇒    Hence, option c is a polynomial expression.

d) 6x+4​. This expression is also a polynomial expression as all of the variables have positive integer exponents.

      ⇒   Hence option d is a polynomial expression.

The solutions to the equation (cosθ)(cosθ + 1) = 0 in the interval 0 ≤ θ < 2π are θ = π/2 and θ = 3π/2.

To solve the equation (cosθ)(cosθ + 1) = 0, we set each factor equal to zero and solve for θ.

First, consider the factor cosθ = 0. In the interval 0 ≤ θ < 2π, the cosine function is equal to zero at two points: θ = π/2 and θ = 3π/2. These are the solutions corresponding to the first factor.

Next, consider the factor cosθ + 1 = 0. Subtracting 1 from both sides gives cosθ = -1. In the interval 0 ≤ θ < 2π, the cosine function is equal to -1 at θ = π. However, this solution is not valid because it does not satisfy the given interval.

Therefore, the solutions to the equation (cosθ)(cosθ + 1) = 0 in the interval 0 ≤ θ < 2π are θ = π/2 and θ = 3π/2. These are the values of θ for which the equation is satisfied and the factors equal zero.

The value of x in the circle is 3.

We have,

In geometry, a secant is a line that intersects a circle at two distinct points.

The formula for two secant segments on a circle states that the product of the lengths of one secant segment and its external segment is equal to the product of the lengths of the other secant segment and its external segment.

We will use the formula for two secants on a circle.

So,

There are two secant segments on the circle.

This means,

5 x (5 + 3x + 1) = 6 x (6 + 2x)

Now,

Solve for x.

5 x (5 + 3x + 1) = 6 x (6 + 2x)

Distributive property.

5 x (6 + 3x) = 6 x (6 + 2x)

Adding like terms

30 + 15x = 36 + 12x

15x - 12x = 36 - 30

2x = 6

Divide 2 on both sides.

x = 3

We have to determine whether the given series converges or diverges. The given series is as follows: `(n+4)! / 4!(n!)` Let's use the ratio test to find out if this series converges or diverges.

The Ratio Test: It is one of the tests that can be used to determine whether a series is convergent or divergent. It compares each term in the series to the term before it. We can use the ratio test to determine the convergence or divergence of series that have positive terms only. Here, a series `Σan` is convergent if and only if the limit of the ratio test is less than one, and it is divergent if and only if the limit of the ratio test is greater than one or infinity. The ratio test is inconclusive if the limit is equal to one. The limit of the ratio test is `lim n→∞ |(an+1)/(an)|` Let's apply the Ratio test to the given series.

`lim n→∞ [(n+5)! / 4!(n+1)!] * [n!(n+1)] / (n+4)!` `lim n→∞ [(n+5)/4] * [1/(n+1)]` `lim n→∞ [(n^2 + 9n + 20) / 4(n^2 + 5n + 4)]` `lim n→∞ (n^2 + 9n + 20) / (4n^2 + 20n + 16)`

As we can see, the limit exists and is equal to 1/4. We can say that the given series converges. The series converges. To determine the convergence of the given series, we use the ratio test. The ratio test is a convergence test for infinite series. It works by computing the limit of the ratio of consecutive terms of a series. A series converges if the limit of this ratio is less than one, and it diverges if the limit is greater than one or does not exist. In the given series `(n+4)! / 4!(n!)`, the ratio test can be applied. Using the ratio test, we get: `

lim n→∞ |(an+1)/(an)| = lim n→∞ [(n+5)! / 4!(n+1)!] * [n!(n+1)] / (n+4)!` `= lim n→∞ [(n+5)/4] * [1/(n+1)]` `= lim n→∞ [(n^2 + 9n + 20) / 4(n^2 + 5n + 4)]` `= 1/4`

Since the limit of the ratio test is less than one, the given series converges.

The series converges to some finite value, which means that it has a sum that can be calculated. Therefore, the answer is a).
