The length of each piece to the nearest inch is 16 inches.

Division is one of the operation in mathematics where number is divided  into equal parts as that of a definite number.

Given that,

Total length of the board = 2 meters

Gillian cuts the board into 5 equal pieces.

Length of each piece of the board in meters = 2 / 5 = 0.4 meter

We know that,

1 meter = 39.37 inches

0.4 meter = 39.37 × 0.4

The minimum sample size required will be 231.

What is Sample Size?

The act of deciding how many observations or replicates to include in a statistical sample is known as sample size determination. The sample size is an important aspect of any empirical study whose purpose is to draw conclusions about a population from a sample.

The sample size(n) is 2558.

p = 46%

= 0.46 sample fraction of US adults who had experienced with substance misuse in their relatives

1) Where, 0.05/2 (n is the crucial value of z for two tailed test at 0.05 level of significance = 1.96) is the 95% CI for the population proportion of adults in the United States who had dealt with substance misuse in their family (P). (This can be acquired from the z table by locating the z that corresponds to an area close to 0.05/2).

Hence, the confidence interval is given by

= [0.46 ± 0.02]

= [0.44, 0.48]

As a result, we are 95% confident that the population share of US individuals who have experienced substance misuse in their relatives will fall between 0.44 and 0.48

2) Margin of error = E

= 0.02

3) Null hypothesis  0.4 percent of US people have dealt with substance misuse in their families.

P = 4/10

= 0.4

Alternative hypothesis  More than 0.5 percent of US individuals have dealt with substance misuse in their relatives.

P > 0.4

95% confidence interval is - [0.44, 0] 48]

We may reject the null hypothesis since the confidence interval does not include the null value of population proportion (0.4)

As a result, we have enough evidence that more than four out of every ten US adults have dealt with substance misuse in their families.

As a result, the newspaper could make the assertion.

4) According to the Gallop Poll poll of 2558 US individuals, more than four out of ten US citizens have dealt with substance misuse in their families.

5) The required minimum sample size is given by:

P is the specified value of population proportion under the null hypothesis = 0.4

= (1.96/0.02)²  (0.4) (1 - 0.4)

= [tex]98^{2}[/tex] (0.4) 0.6

= 230.5

So, the minimum sample size required will be 231.

The team is predicted to win 56.2% of its games this season.

What is probability?

By simply dividing the favorable number of possibilities by the entire number of possible outcomes, the probability of an occurrence can be determined using the probability formula. Because the favorable number of outcomes can never exceed the entire number of outcomes, the chance of an event occurring might range from 0 to 1. The probability can also be expressed as in form of a percentage as we multiply it by 100.

It's the middle of a season, and Bill James has calculated the Pythagorean Winning Percentage (W%) of a team as .562.

To convert, the probability to percentage just multiply by 100 =.562*100

= 56.2%.

The time that Nagma takes to complete five rounds is 0.4 hours or 24 minutes.

Travel time is the total time required to pass a certain length of road.

Given,

Length = 180m

Width = 120 m

Speed = 7.5 km/hr

Time of five rounds?

Steps,

The first step that must be done is to find the travel time for one round

Distance of one round = 2(length + width)

Distance of one round = 2(180 + 120)

Distance of one lap = 3 (300)

Distance of one round = 600 m = 0.6 km

Time needed to reach 5 rounds

Time = 5 (distance : speed)

Time = 5 (0.6 : 7.5)

The fully simplified form of the expression is [tex]\frac{3}{2x+12}-\frac{-3}{x-8} +\frac{4}{x+6}[/tex]

A quadratic equation is a type of polynomial equation that has the general form ax^2 + bx + c = 0, where a, b, and c are coefficients and x is an unknown variable. The equation has two solutions, which can be found using the quadratic formula x = (-b ± √(b^2 - 4ac)) / 2a, where the ± symbol indicates that there are two possible solutions.

Quadratic equations are used to model a variety of real-world phenomena, such as the motion of objects under the influence of gravity, the path of a projectile, and the growth of a population over time. They are also used to describe the parabolic shape of curves and to solve optimization problems, such as finding the maximum or minimum value of a function

We can simplify the expression as follows:

[tex]\frac{3}{2x+12} =\frac{x-15}{x^{2} -2x-48}[/tex]

First, we'll simplify the denominators. To do this, we can factor the quadratic expression x² - 2x - 48:

x² - 2x - 48 = (x - 8)(x + 6)

Now we can rewrite the denominators:

[tex]\frac{3}{2x+12}-\frac{x-15}{(x-8)(x+6)}[/tex]

Next, we'll simplify the fraction in the second term using partial fraction decomposition:

[tex]\frac{x-15}{(x-8)(x+6)} =\frac{A}{x-8}+\frac{B}{x+6}[/tex]

where A and B are constants that we can find by multiplying both sides by (x - 8)(x + 6) and equating the numerators:

x - 15 = A(x + 6) + B(x - 8)

Expanding both sides:

x - 15 = Ax + 6A + Bx - 8B

Comparing coefficients:

-15 = Ax + 6A + Bx - 8B

1 = A + B

8B = Ax + 6A + 15

-6A = -15 - Ax - 8B

-6A = -15 - (A + B)x - 8B

-6A = -15 - x + 7x

-6A = -15 - x + 7x

-6A = -15 + 6x

Solving for A and B, we have:

A = -3

B = 4

So, the second term can be written as:

[tex]\frac{x-15}{(x-8)(x+6)} =\frac{-3}{x-8}+\frac{4}{x+6}[/tex]

Putting everything together, we have:

[tex]\frac{3}{2x+12} -\frac{x-15}{(x-8)(x+6)} =\frac{3}{2x+12}-\frac{-3}{x-8} +\frac{4}{x+6}[/tex]

The given equation does not represent y as a function of x.

A relation is a function if for every unique x value, there exists only one unique y value. The equation 5x³y = 15 does not define a unique value for y for a given value of x, and therefore does not represent y as a function of x.

The equation 5x³y = 15 does not represent y as a function of x. A function must have exactly one output value for each input value, but this equation doesn't have the unique output restriction.

The equation 5x³y = 15 represents a 3-dimensional surface in the x-y-z plane, where z = 5x³y. It does not define y as a function of x, because for a given x there can be multiple values of y that satisfy the equation. To define y as a function of x, additional information, such as an equation that relates y and x in a one-to-one manner, is needed.

The speed of the passenger train is 80 mph.

Let's call the speed of the passenger train "p" and the speed of the freight train "f". We know that "p" = "f" + 14, and that the time it takes for the two trains to cover their respective distances is the same.

Therefore, we can write the equation:

400/p = 330/f

Expanding the second term and substituting "p" for "f" + 14:

400/p = 330/(p - 14)

Cross multiplying and simplifying:

400 * (p - 14) = 330 * p

Expanding both sides:

400p - 5600 = 330p

Subtracting 330p from both sides:

70p = 5600

Dividing both sides by 70:

p = 80 mph

Using system of equation,

let

x = cost of each ticket in Japan

y = cost of each ticket in Switzerland

Therefore,

3x + 2y = 77.75

2x + 3y = 73.75

Multiply equation(ii) by 1.5

3x + 2y = 77.75

The solution of the initial value problem is [tex]y = (t^3/3 + t^2 + t + 6)e^{(t^3/3 + t)}[/tex]

A differential equation is a mathematical equation that relates a function and its derivatives to some independent variables.

In this case, the differential equation is given by:

dy/dt = t² + 1, t ≥ 0

with the initial value y = 6 when t = 0.

To solve this initial value problem, we can use the method of integrating factor.

We can find the integrating factor for this differential equation by using the formula:

[tex]= > e^{\intP(t)dt,[/tex]

where P(t) = t² + 1

So,

[tex]= > e^{\int P(t)dt} = e^{t^3/3 + t}[/tex]

By the product rule, we have:

[tex]= > d/dt(e^{t^3/3 + t)y} = d/dt(e^{t^3/3 + t)(t^2 + 1)})[/tex]

We can evaluate the integral on the right side using standard integration techniques, and we get:

[tex]= > e^{t^3/3 + t}y = e^{(t^3/3 + t)(t^3/3 + t^2 + t + C)[/tex]

Finally, we can isolate y by dividing both sides of the equation by e^(t^3/3 + t):

[tex]= > y = (t^3/3 + t^2 + t + 6)e^{(t^3/3 + t)}[/tex]

To find the value of C, we can use the initial value y = 6 when t = 0:

6 = Ce⁰

So, C = 6.
