The digit replacements for x in the number 95,768,24x that make it divisible by  4 is either 0, 4, or 8.

To evaluate the digit replacements for x in the number 95,768,24x that make it divisible by 4, we need to determine the possible values for x that satisfy this condition.

For a number to be divisible by 4, the last two digits must be divisible by 4. Therefore, we need to find the values of x that make the number 24x divisible by 4.

The possible values for x that make 24x divisible by 4 are 0, 4, 8. This is because any multiple of 4 ends in 0, 4, 8 when the tens and units place are considered.

Therefore, the possible digit replacements for x are 0, 4, and 8. These values will make the number 95,768,24x divisible by 4.

Hence, the digit that will make the first number divisible by 4 is either 0, 4, or 8.

Let the each angle be x , 2x and 3x.

→ x + 2x + 3x = 5600

→ 8x = 5600

→ x = 5600/8

→ x = 700

the value of x is Rs.700.

Now, 2x = 2×700 = 1400

, 3x = 3×700 = 2100

Each one will get Rs.700 , Rs.1400 and Rs. 2100.

With 90% confidence, the lower confidence limit (LCL) for the mean winnings is approximately $34,955.09 and the upper confidence limit (UCL) is approximately $40,485.31.

The mean winnings for all the show's players with a 90% confidence level, we can use the formula for a confidence interval for the population mean.

The sample of winnings:

30,692, 43,231, 48,269, 28,592, 28,453, 36,309, 45,318, 36,362, 42,871, 39,592, 35,456, 40,775, 36,466, 36,287, 38,956

We can calculate the sample mean (x(bar)) and the sample standard deviation (s) from the given data.

Sample mean

(x(bar)) = (30,692 + 43,231 + 48,269 + 28,592 + 28,453 + 36,309 + 45,318 + 36,362 + 42,871 + 39,592 + 35,456 + 40,775 + 36,466 + 36,287 + 38,956) / 15

≈ 37,720.2

Sample standard deviation

s = √[((30,692 - 37,720.2)² + (43,231 - 37,720.2)² + ... + (38,956 - 37,720.2)²) / (15 - 1)]

≈ 6,522.45

The standard error (SE) of the mean is calculated as SE = s /√n, where n is the sample size.

Standard error (SE) = 6,522.45 / √15 ≈ 1,682.12

To calculate the confidence interval, we need to find the critical value corresponding to a 90% confidence level. For a 90% confidence level, the critical value is approximately 1.645.

Margin of error = Critical value × Standard error

= 1.645 × 1,682.12

≈ 2,765.11

Lower confidence limit (LCL) = Sample mean - Margin of error

= 37,720.2 - 2,765.11

≈ 34,955.09

Upper confidence limit (UCL) = Sample mean + Margin of error

= 37,720.2 + 2,765.11

≈ 40,485.31

Therefore, with 90% confidence, the lower confidence limit (LCL) for the mean winnings is approximately $34,955.09 and the upper confidence limit (UCL) is approximately $40,485.31.

Step-by-step explanation:

Answer:

8 + (-43) - 1152 =  -1187

Step-by-step explanation:

The solution to a system of the type x2=A+f(t) must be 22 and is given in:

(a) Eigenvalues: λ = -2, 11. Eigenvectors: (1, 1), (-1, 1).

(b) Particular solution: [tex]\begin{equation}x = -\frac{1}{13}e^{-2t} + \frac{1}{13}e^{11t} + f(t)[/tex]

(c) General solution: [tex]\begin{equation}x = c_1e^{-2t} + c_2e^{11t} - \frac{1}{13}e^{-2t} + \frac{1}{13}e^{11t}[/tex]

(d) Second linearly independent solution: x = 22t - 23.

Here is the explanation :

(a) The system is of the form x' = Ax + f(t), where A is a 2x2 matrix and f(t) is a 2x1 vector-valued function. The characteristic equation of A is |A - λI| = 0, which in this case gives us λ² + λ - 22 = 0. The eigenvalues are λ = -2 and λ = 11. The eigenvectors corresponding to these eigenvalues are (1, 1) and (-1, 1), respectively.

(b) The particular solution to the system in (a) is given by [tex]\begin{equation}x = c_1e^{-2t} + c_2e^{11t} + f(t)[/tex].

The function f(t) must satisfy the initial conditions x(0) = (1, -6) and x'(0) = (-2, 1). Using these initial conditions, we can find [tex]c_1[/tex] and [tex]c_2[/tex] as follows:

[tex]\begin{equation}c_1 = \frac{1 - 6}{-2 - 11} = -\frac{1}{13}[/tex]

[tex]\begin{equation}c_2 = \frac{-2 + 1}{-2 - 11} = \frac{1}{13}[/tex]

Therefore, the particular solution to the system is

[tex]\begin{equation}x = -\frac{1}{13}e^{-2t} + \frac{1}{13}e^{11t} + f(t)[/tex]

(c) The general solution to the system is given by [tex]\begin{equation}x = c_1e^{-2t} + c_2e^{11t} + u[/tex], where u is a particular solution to the system. In this case, we have already found [tex]\begin{equation}u = -\frac{1}{13}e^{-2t} + \frac{1}{13}e^{11t}[/tex].

Therefore, the general solution to the system is [tex]\begin{equation}x = c_1e^{-2t} + c_2e^{11t} - \frac{1}{13}e^{-2t} + \frac{1}{13}e^{11t}[/tex].

(d) The system has a repeated eigenvalue of -1, and Fire is one solution to the system. The second linearly independent solution can be found using the method of variation of parameters. In this method, we assume that the second solution is of the form x = vt + w, where v and w are constants to be determined. Substituting this into the system gives us the following equations:

-2v + w = -21

v + 11w = -1

Solving these equations gives us v = 22 and w = -23. Therefore, the second linearly independent solution is x = 22t - 23.

Step-by-step explanation:

To find all real values of x for which f(x) equals zero, we need to solve the equation f(x) = 0. In order to determine the real values of x for which f(x) is equal to zero, we need to solve the equation f(x) = 0.

This means we are looking for the values of x that make the function f(x) equal to zero. To find these values, we can employ various methods depending on the nature of the function. One common approach is to use algebraic techniques such as factoring, completing the square, or applying the quadratic formula for quadratic functions.

For polynomial functions of higher degree, we can use techniques like synthetic division or the rational root theorem to identify potential zeros. Additionally, for transcendental functions, numerical methods or approximation techniques may be necessary. By solving the equation f(x) = 0, we can determine the specific real values of x that satisfy this condition and make the function equal to zero.

The solution to f(x) = g(x) can be found by looking at the point where the graphs of the two functions intersect.

The given functions are: f(x) = 73x - 3g(x) = 2x - 4. To find the solution, we need to set f(x) = g(x) and solve for x.73x - 3 = 2x - 4. Simplifying the above expression, we get: 71x = 1x = 1/71.Therefore, the solution to f(x) = g(x) is x = 1/71. Now let's look at the given graph: From the graph, we can see that the solution x = 1/71 is not listed as one of the answer choices.

However, we can see that the point of intersection of the two lines is at approximately x = 0.02. Therefore, the correct answers are: 0 (since x = 0.02 is rounded to the nearest whole number, which is 0) and2 (since the point of intersection has an x-coordinate of approximately 0.02, which is between 0 and 3).Therefore, the correct answers are:0 and 2.

The functions are differentiable at all the z-plane is f'(z) = 2x when function is f(z) = x² + y² + i2xy.

Given that,

The function is f(z) = x² + y² + i2xy

We have to determine if the functions are differentiable throughout the z-plane or only a portion of it, and then we must assess any derivatives that may exist.

We know that,

Take the function,

f(z) = x² + y² + i2xy

f(x + iy)  = x² + y² + i2xy

f(x + iy)  = u + iv

We can say, u =x² + y², v= 2xy

Differentiate u with respect to x

uₓ = 2x

Differentiate v with respect to y

[tex]v_y[/tex] = 2x

So,

uₓ = 2x = [tex]v_y[/tex]

uₓ = [tex]v_y[/tex]

Differentiate u with respect to y

[tex]u_y[/tex] = 2y

Differentiate v with respect to x

[tex]v_x[/tex] = 2y

So,

[tex]u_y[/tex] = -[tex]v_x[/tex] = -2y ⇒ y = 0

Let D = {z : x | x, y∈R}

f is differentiable on D.

The derivative is f'(z) = [tex]u_x + iv_x[/tex] = 2x

Therefore, the functions are differentiable at all the z-plane is f'(z) = 2x.

Remark

If x - 2 is a factor it means that the whole equation will return 0 when x = 2. That's because x - 2 will go to 0. It doesn't matter what the rest of the equation factors into. The x - 2 is enough to make it all go to 0.

Equation

y = x^4 - 3x^3 +2x - 8

Substitute and Solve

x = 2

y = 2^4 - 3*2^3 + 2(3) - 8

y = 16 - 24 + 6 - 8

y = - 8 - 2

Step-by-step explanation:

The equation is in slope-intercept form, which is y = mx + b.

To graph the line, first we have to find the slope, m, and the y- intercept, b.

So, the slope is 2 and the y- intercept is 1.

We can graph this, beginning with the y- intercept, 1. The y- intercept is always on the y axis, so the (x) value will always be zero.

Plot a point at (0, 1).

Next, add more points using the slope. The slope is 2, or [tex]\frac{2}{1}[/tex]. Start at the point we have made on the y axis. The slope equals the [tex]\frac{rise}{run}[/tex]. We can rise 2 units, then run one more unit to the right. If the slope is negative, the run goes to the left. However, in this case, the slope is positive, to it slants to the right.

We end on point (1, 3). We can continue this path infinitely, some other points on the graph could be (2, 5), (3, 7), (4, 9) and (5, 11).

Connect these points to make a line.
