Answer:

\( \frac{x}{4} + \frac{1}{2} = \frac{1}{8} \)

\( \frac{x}{4} = - \frac{3}{8} \)

\(x = - \frac{3}{2} = - 1 \frac{1}{2} \)

The solution to the equation x/4 + 1/2 = 1/8 is x = -3/2.

Consider the equation, we have only one x term, so taking all the terms without x to the other side and terms with x on one side.

x/4 + 1/2 = 1/8

Take the 1/2 term on the other side,

x/4=1/8 - 1/2

Taking the LCM on the Right side,

x/4 = (1-4) / 8

x/4 = -3/8

Now, we have x/4 so what we can do is, shift the 4 to the other side too, we get,

x = ( -3/8) * 4

x = -3/2

The solution to the equation x/4 + 1/2 = 1/8 is x = -3/2.

a)The probability of exactly 5 accidents will occur is 0.1008.

b) The probability of fewer than 3 accidents will occur is 0.42318.

It is predicated on the likelihood that something will occur. The justification for probability serves as the basic foundation for theoretical probability. For instance, the theoretical chance of receiving a head while tossing a coin is 12. Mathematics' study of random events is known as probability, and there are four primary types of probability: axiomatic, classical, empirical, and subjective. Since probability is the same as possibility, you could say that it is the likelihood that a specific event will occur.

Given,

Mean = 3

a) By using Poission probability formula,

P( X = 5) = e⁺³ (3)⁵/5!

P(X = 5) = 0.1008

The probability of exactly 5 accidents will occur is 0.1008.

b) fewer than 3 accidents will occur:

P( X <3) = e⁻³ (3)⁰ + e⁻³ (3)¹ + e⁻³(3)²

P( X< 3) = 0.4978 + 0.14936 + 0.22404

P( X < 3) = 0.42318

The probability of fewer than 3 accidents will occur is 0.42318.

Answer:

The large box weighs 18.75 and the small box weights 15.75

Step-by-step explanation:

We are looking to find 2 variables so we will need two equations.

Let l = the large box weight

Let s = the small box weight

7l + 9s + 273                   5l +3s = 141

I want to add these two equations together and have one of the variables be eliminated.  The way both equations are written now, neither variable will drop out.  I see that 9 is a multiple of 3.  If I multiply the second equation all the way through by - 3, the s variable will be eliminated.

-3(5l +3s) -3(141)  Multiple everything by -3

-15l -9s = -423  Now I will add this to the original equation 7l + 9s = 273

7l + 9s = 273

-8l = -150  Divide both sides by -8

l = 18.75  This is the weight of the large box.

Plug in 18.75 to either of the ordinal equations to find the weight of the small box.

5l + 3s = 141

5(18.75) + 3s = 141  Distribute the 5

93.75 + 3s = 141  Subtract 93.75 from both sides

3s = 47.25  Divide both sides by 3

s = 15.75

Check:

Plug in 15.75 for s and 18.75 for l into both of the original equation to see if they equal.

7l + 9s = 273

7(18.75) + 9(15.75) =273

131.25 + 141.75 = 273  Checks

5l + 3s = 141

5(18.75) + 3(15.75) = 141

93.75 + 47.25 = 141

141 = 141 Checks

The correct statement among the given options is "The rate at which the volume of liquid in the container is decreasing at the instant when the depth is 1 m is 4.5√7. dV/dh = 6h√(3h² + 4)."

In the given problem, the volume of liquid in the container is given by V = (3h² + 4)³ - 8, where h is the depth of the liquid in meters.

To find the rate at which the volume is decreasing with respect to the depth, we need to take the derivative of V with respect to h, dV/dh.

Differentiating V with respect to h, we get dV/dh = 3(3h² + 4)²(6h) = 18h(3h² + 4)².

At the instant when the depth is 1 m, we can substitute h = 1 into the equation to find the rate of volume decrease.

Evaluating dV/dh at h = 1, we get dV/dh = 18(1)(3(1)² + 4)² = 18(7) = 126.

Therefore, the rate at which the volume of liquid in the container is decreasing at the instant when the depth is 1 m is 126 m³/hr.

Hence, the correct statement is "The rate at which the volume of liquid in the container is decreasing at the instant when the depth is 1 m is 4.5√7. dV/dh = 6h√(3h² + 4)."

The given statement "We can represent the pdf of a discrete random variable x with a histogram." is True, because histograms are often used to graphically represent the distribution of a discrete random variable.

In a histogram, the x-axis represents the different possible values of the discrete random variable, and the y-axis represents the probability or frequency of observing each value. The bars in the histogram represent the probabilities or frequencies of the different values, and the height of each bar corresponds to the probability or frequency.

Note that for a discrete random variable, the PDF is actually a probability mass function (PMF), which gives the probability of each possible value of X. However, the histogram can be used to represent the PMF by scaling the heights of the bars appropriately so that they represent probabilities rather than frequencies.

The series representation is as follows: f(x) = x^3 * (1 / (x - 5)^2) = x^3 * (1 / (25 - 10x + x^2)) = x^3 * (1 / 25) * (1 / (1 - (10/25)x + (1/25)x^2)). The power series representation of the function f(x) = (x^3)/((x - 5)^2) can be found by using the geometric series expansion and the binomial theorem.

1. Now, we can recognize the form of a geometric series (1 / (1 - r)), where r = (10/25)x - (1/25)x^2. By applying the geometric series expansion, we have: f(x) = (x^3 / 25) * (1 + (10/25)x - (1/25)x^2 + (10/25)^2 * x^2 - (10/25)^3 * x^3 + ...)

2. This power series representation of f(x) shows that it can be expressed as a sum of terms multiplied by powers of x. The coefficients of the terms are obtained from the binomial expansion of (1 / (1 - r)). The terms involving higher powers of x correspond to higher-order derivatives of f(x) evaluated at x = 0.

To solve the differential equations given in the question, we will use Laplace transforms. So let's start:Solution:a) y" – y = t y(0) = 1, y'(0) = 1First, we take the Laplace transform of the given differential equation.L{y" - y} = L{ty}

Taking the Laplace transform of both sides gives:L{y"} - L{y} = L{ty}Using the formula, L{y"} = s²Y(s) - s*y(0) - y'(0), and L{y} = Y(s) then we get:s²Y(s) - s - 1 = (1/s²) + (1/s³)Rearranging the above equation, we get:Y(s) = [1/(s²*(s² + 1))] + [1/(s³*(s² + 1))]Now, we apply the inverse Laplace transform to find the solution.y(t) = (t/2)sin(t) + (cos(t)/2)

write the given equation in a standard form

3x + 4y = 6

4y = 6 - 3x

4y = - 3x + 6

divided by 4 in both sides

y = - 4/3x + 3/2

standard form of a linear equation is

y = mx +c

therefore m for gradient is -4/3

the product of the gradient of the lines that are perpendicular to each other is -1

- 4/3 × mx = -1

mx = 3/4

y = mx + c

-5 = 3/4(2) + c

-5 = 3/2 + c

c = -13/2

therefore your equation is

y = 3/4x - 13/2

Answer:

y = –5x – 17

Step-by-step explanation:

First, we shall determine the slope of the equation y = 1/5x – 3.

The slope of the equation y = 1/5x – 3 can be obtained by comparing the equation with y = mx + c.

This is illustrated below:

y = 1/5x – 3

y = mx + c

Thus, the slope (m) of equation

y = 1/5x – 3 is 1/5

Next, we shall determine the slope of the line perpendicular to the equation as follow:

For perpendicular lines, their slope (m1 and m2) are related as follow:

m1 × m2 = –1

m1 = 1/5

1/5 × m2 = –1

m2/5 = –1

Cross multiply

m2 = 5 × –1

m2 = –5

Therefore, the slope of the line is –5.

Finally, we shall determine the equation of the line as follow:

Coordinate = (–5, 8)

x1 coordinate = –5

y1 coordinate = 8

Slope (m) = –5

y – y1 = m(x –x1)

y – 8 = –5(x – (–5))

y – 8 = –5(x + 5)

y – 8 = –5x – 25

Rearrange

y = –5x – 25 + 8

y = –5x – 17

Therefore, the equation is y = –5x – 17.

The required point is 0.25 miles away from the nearest point on the shore.

The differentiation of a function is defined as rate of change of its value at a point. It can be written as f'(x) =  lim h--> 0 (f(x + h) - f(x)) /(x + h - x).

here, we have,

It can be applied to minimize or maximize a function.

The given problem can be shown in the form of a diagram as follows

Suppose the underwater cable meet the shore at a distance x from the nearest point.

Then, the distance of cable in water is x² + 3.5² = x² + 12.25

And, the distance of cable in the ground is 10 - x.

As per the question, the cost of the laying cable can be represented as follows,

C(x) = 1200(10 - x) + 2400(x² + 12.25)

In order to minimize the cost the above function can be differentiated and equated to zero as,

C'(x) = -1200 + 4800x = 0

=> x = 1200/4800

      = 1/4

      = 0.25

Hence, in order to minimize the cost of the entire project the underwater cable should meet the shore at 0.25 miles away from the nearest point.

Given the equation:

The equation is at Slope-Intercept Form: y = mx + b and the m in the equation represents the slope of the line. Therefore, the slope of the line that represents the equation y = 2x - 6 is 2.

It's been given that the equation of the line that we are looking for is parallel to y = 2x - 6 and passes through the point (3, -8). Thus, we will adapt the slope of the equation and determine the y-intercept by substituting the coordinates in the slope-intercept formula y = mx + b.

We get,

At slope, m = 2 and x,y = 3, -8:

Let's substitute m = 2 and b = -14 to y = mx + b to complete the formula:

Therefore, the equation of the line parallel to y = 2x - 6 and passes through (3, -8) is

y = 2x - 14.
