Answer:

Option B: II only

Step-by-step explanation:

Looking at the statements;

In statement I, whether making big at once or small deposits periodically, they have no impact in terms of charges from banks because banks don't charge any excessive fee for direct deposits.

In statement II, using out of network ATM would mean more excessive service fees. This is because your host bank which issued you the ATM card will charge you for using a non - network machine. In addition to that, the ATM operator where you are withdrawing from will also charge you a fee. This is double charge from 2 streams thus avoiding it will mean no excessive charges.

In statement III, some banks may or may not issue some fee for making online transactions with debit card depending on what exactly you want to do. However, it's just a small fee and thus, using it doesn't cause excessive charges.

Thus, the one to avoid will be statement II.

Answer:

Line of symmetry: Yes (It has 2, Diagonally, and vertically)

Parallel sides: Yes (Side 1 and side 2 and top line 1 and top line 2 are parallel)

Perpendicular sides: No (No right angles are present by the connecting lines)

Obtuse angles: Yes (All the touching lines are obtuse angles)

Step-by-step explanation:

the easiest approach seems to be the law of sines :

a/sin(A) = b/sin(B) = c/sin(C)

where the sides and the angles are always opposite of each other.

we have here a right-angled triangle, so the angle opposite of 10 is 90 degrees.

10/sin(90) = 10/1 = 10 = y/sin(37)

y = 10×sin(37) = 6.018150232 ≈ 6.0

We would divide the value in the y2 x1 cell (55) by the marginal total for x1, which gives us 55/95 = 0.579.

The conditional distribution by x for the given contingency table is:

X1: y1 = 0.364, y2 = 0.636

X2: y1 = 0.308, y2 = 0.692

X3: y1 = 0.217, y2 = 0.783

To find the conditional distribution by x, we need to divide each value in the contingency table by the corresponding marginal total. For example, to find the conditional probability of y1 given x1, we would divide the value in the y1 x1 cell (40) by the marginal total for x1 (40+55),

which gives us 40/95 = 0.421. To find the conditional probability of y2 given x1, we would divide the value in the y2 x1 cell (55) by the marginal total for x1, which gives us 55/95 = 0.579. We repeat this process for each cell in the table, and round the values to the nearest thousandth.

In summary, the conditional distribution by x tells us the probability of each value of y given a specific value of x.

It is useful for analyzing relationships between two categorical variables, and can provide insights into how the distribution of one variable differs across different categories of another variable.

The average time it takes to rent a video tape is 0.141 minutes.

Given data:Customers arrive at a video rental desk at the rate of 12 per minute(Poisson).
Each server can handle 8.15 customers per minute(Poisson). If there are 3 servers, we need to determine the average time it takes to rent a video tape.
Let us assume λ = 12 and μ = 3 × 8.15 = 24.45
Average time it takes to rent a video tape = 1 / (μ - λ/n)
Where, n = number of servers⇒ Average time it takes to rent a video tape = 1 / (24.45 - 12/3)⇒ Average time it takes to rent a video tape = 1 / 8.45⇒ Average time it takes to rent a video tape = 0.1185 minutes = 0.141 rounded to three decimal places.

The general solution to the given differential equation is \(y = cx^2 - 2x^3,\) where c is a constant.

To find the general solution, we first rearrange the given differential equation in the standard form of a linear first-order equation. The equation is:

x^2y' - 2xy = 4

We can rewrite this equation as:

\(y' - (2/x)y = 4/x^2\)

This is now in the form of a linear first-order equation, where the coefficient of y' is 1. To solve this type of equation, we use an integrating factor, which is given by the exponential of the integral of the coefficient of y. In this case, the integrating factor is:

IF = e^(-∫2/x dx) = e^(-2ln|x|) = e^(ln|x|^(-2)) = 1/x^2

Multiplying the entire equation by the integrating factor, we get:

\((1/x^2)y' - 2/x^3 y = 4/x^4\)

Now, the left-hand side of the equation can be written as the derivative of the product of the integrating factor and y:

\(d/dx [(1/x^2)y] = 4/x^4\)

Integrating both sides with respect to x, we have:

\(∫d/dx [(1/x^2)y] dx = ∫4/x^4 dx\)

\(∫(1/x^2)y dx = -4/x^3 + C\)

Integrating the left-hand side gives:

\(-(1/x)y + C = -4/x^3 + C\)

Simplifying further, we get:

\(y = cx^2 - 2x^3\)

where c is the constant obtained by combining the arbitrary constant C with the constant of integration.

If a system of n linear equations in n unknowns is inconsistent, then the rank of the matrix of coefficients is n is (c) Never true.

If a system of n linear equations in n unknowns is inconsistent, it means that there are no solutions that satisfy all the equations simultaneously. In this case, the rank of the matrix of coefficients cannot be equal to n. The rank of a matrix represents the maximum number of linearly independent rows or columns in the matrix.

If the system of equations is inconsistent, it implies that there must be at least one row in the matrix of coefficients that can be expressed as a linear combination of the other rows. Consequently, the rank of the matrix will be less than n because it cannot have n linearly independent rows.

Therefore, it is never true that the rank of the matrix of coefficients in an inconsistent system of n linear equations in n unknowns is equal to n.

Therefore, the compound interest of the annuity due of BD 400 paid each 4 months for 6.2 years at a nominal rate of 3% per annum is BD 40,652.17.

Compound interest of an annuity due can be calculated using the formula:A = R * [(1 + i)ⁿ - 1] / i * (1 + i)

whereA = future value of the annuity dueR = regular paymenti = interest raten = number of payments First, we need to calculate the effective rate of interest per period since the nominal rate is given per annum. The effective rate of interest per period is calculated as

:(1 + i/n)^n - 1 = 3/1003/100 = (1 + i/4)^4 - 1

(1 + i/4)^4 = 1.0075i/4 = (1.0075)^(1/4) - 1i = 0.0303So,

the effective rate of interest per 4 months is 3.03%.Next, we can substitute the given values in the formula:

A = BD 400 * [(1 + 0.0303)^(6.2 * 3) - 1] / 0.0303 * (1 + 0.0303)A = BD 400 * [4.227 - 1] / 0.0303 * 1.0303A = BD 400 * 101.63A = BD 40,652.17

Answer:

Length = 200 m

Breadth = 175 m

Step-by-step explanation:

Perimeter of the rectangular field = Total cost ÷ rate per metre

                                                        = 12000 ÷ 16

                                                        = 750 m

Length : breadth = 8 : 7

Length = 8x

Breadth = 7x

Perimeter = 750

2*(length + breadth) = 750

2*(8x + 7x) = 750

2* 15x = 750

  30x = 750

      x = 750/30

x = 25

Length = 8x = 8*25 = 200 m

Breadth = 7*25 = 175 m

Answer:

v=20π ft/s

Step-by-step explanation:

Given:

Distance from the security car to the movie theater, D=25 ft

Distance of the reflection from the car, d=30 ft

Speed of rotation of the strobe lights, 2 rev/s

To find the speed at which the reflection of the security strobe lights is moving along the wall of the movie theater, we need to calculate the linear velocity of the reflection when it is 30 ft from the car.

We can start by finding the angular velocity in radians per second. Since the strobe lights rotate at 2 revolutions per second, we can convert this to radians per second.

ω=2πf

=> ω=2π(2)

=> ω=4π rad/s

The distance between the security car and the reflection on the wall of the theater is...

r=30-25= 5 ft

The speed of reflection is given as (this is the linear velocity)...

v=ωr

Plug our know values into the equation.

v=ωr

=> v=(4π)(5)

∴ v=20π ft/s

Thus, the problem is solved.

The speed of the reflection of the security strobe lights along the wall of the movie theater is 2π ft/s.

To solve this problem, we can use the concept of related rates. Let's consider the following variables:

x: Distance between the security car and the movie theater wall

y: Distance between the reflection of the security strobe lights and the security car

θ: Angle between the line connecting the security car and the movie theater wall and the line connecting the security car and the reflection of the strobe lights

We are given:

x = 25 ft (constant)

y = 30 ft (changing)

θ = 2 revolutions per second (constant)

We need to find the speed at which the reflection of the security strobe lights is moving along the wall (dy/dt) when the reflection is 30 ft from the car.

Since we have a right triangle formed by the security car, the movie theater wall, and the reflection of the strobe lights, we can use the Pythagorean theorem:

x^2 + y^2 = z^2

Differentiating both sides of the equation with respect to time (t), we get:

2x(dx/dt) + 2y(dy/dt) = 2z(dz/dt)

Since x is constant, dx/dt = 0. Also, dz/dt is the rate at which the angle θ is changing, which is given as 2 revolutions per second.

Plugging in the known values, we have:

2(25)(0) + 2(30)(dy/dt) = 2(30)(2π)

Simplifying the equation, we find:

60(dy/dt) = 120π

Dividing both sides by 60, we get:

dy/dt = 2π ft/s
