Hey there!!

Here,

\(5(1 - b) = 8(b + 2)\)

\( \: \: \: \: \: 5 - 5b = 8b + 16\)

\( \: \: \: \: \: \: \: 8b + 5b = 5 - 16\)

\( \: \: \: \: \: \: \: 13b = - 11\)

\( \: \: \: \: \: \: \: b = \frac{ - 11}{13} \)

Therefore the value of b is -11/13.

Hope it helps...

Step-by-step explanation:

first open up the brackets according to BODMAS to get

5-5b=8b+16

then collect like terms together and make sure to change the sighns eg - becomes +

5-16=8b+5b

you get

-11=13b

then divide both sides with 13 to get b

-11/13=b ( you can leave as a negative decimal according to the question)

the probability that none of the outcomes is an even number is 1/8 or approximately 0.125

The probability of rolling an even number on a fair six-sided die is 3/6 or 1/2, and the probability of rolling an odd number is also 1/2.

To find the probability that none of the outcomes is an even number, we need to calculate the probability of rolling an odd number on all three dice. Since the dice are rolled independently, we can multiply the probabilities together to get the overall probability:

P(rolling odd on one die) = \(1/2\)

P(rolling odd on two dice) = \((1/2)^2 = 1/4\)

P(rolling odd on three dice) =\((1/2)^3 = 1/8\)

Answer:

The description of the set is \(A = \{s\in \mathbb{C}|\|s\| = 2\}\).

Step-by-step explanation:

From Complex Analysis, we remember that complex numbers are numbers whose form is:

\(s = a+i\, b\), \(a,b \in \mathbb{R}\) (1)

Where \(i = \sqrt{-1}\).

In addition, the distance from the origin is defined by the following Pythagorean identity:

\(\|s\| = \sqrt{a^{2}+b^{2}}\) (2)

The following condition must be satisfied:

\(\|s\| = 2\)

Then, the set of all complex numbers that are at a distance of 2 units from the origin is described below:

\(A = \{s\in \mathbb{C}|\|s\| = 2\}\) (3)

The set of all complex numbers that are at a distance of 2 units from the origin is \(\{z\in \mathbb{C} :\text{ }|z|=2\}\)

A complex number, written in rectangular form is

\(z=a+ib\\a,b\in \mathbb{R}\)

The distance of a complex number from the origin (the modulus of the complex number, denoted by \(|z|\)) is given by the formula

\(|z|=\sqrt{a^2+b^2}\)

Since we want all the complex numbers to be at the distance of 2 units from the origin, they must satisfy

\(|z|=2\)

thus, the set we are looking for is

\(D=\{z\in \mathbb{C} :\text{ }|z|=2\}\)

where \(\mathbb{C}\) is the set of all complex numbers

The correct answer is: c. Gain of £800,000 to Statement of Profit or loss.

Since Maris uses the fair value model, the gain from the increase in the fair value of the building is recognized in the Statement of Profit or Loss. In this case, the building's fair value increased from £10 million to £10.8 million, resulting in a gain of £800,000. Therefore, the gain of £800,000 should be recognized in the Statement of Profit or Loss.According to the fair value model, any gain or loss resulting from the change in fair value of the asset should be recognized in the financial statements. In this case, the increase in the fair value of the building is considered a gain.

Since the gain of £800,000 (the difference between the fair value of £10.8 million and the original purchase price of £10 million) is a result of the change in the asset's fair value, it should be recognized in the Statement of Profit or Loss. This gain represents the increase in the value of the building during the year.

Answer:

The circumference of the back wheel is 2.62 inches

Step-by-step explanation:

Given

\(d_1 = 5in\) --- diameter of front wheel

\(d_1 : d_2 = 3:1\) --- ratio of the diameters

Required

The circumference of the back wheel

First, we calculate the diameter of the back wheel.

We have:

\(d_1 : d_2 = 3:1\)

Substitute: \(d_1 = 5in\)

\(5in: d_2 = 3 : 1\)

Express as fraction

\(\frac{d_2}{5in} = \frac{1}{3}\)

Make \(d_2\) the subject

\(d_2 =5in * \frac{1}{3}\)

\(d_2 = \frac{5}{3}\ in\)

So, the circumference (C) of the back wheel is:

\(C =\pi d\)

\(C = 3.14 * \frac{5}{6}\ in\)

\(C = \frac{3.14 * 5}{6}\ in\)

\(C = \frac{15.7}{6}\ in\)

\(C = 2.62\ in\)

The length of the curve y = ln(cos(x)) for -4π ≤ x ≤ 4π is 16π.

To find the length of the curve y = ln(cos(x)) within the given interval, we can use the arc length formula for a function y = f(x):

L = ∫√(1 + (dy/dx)²) dx,

where dy/dx is the derivative of y with respect to x. In this case, dy/dx = -tan(x). Substituting this value into the arc length formula, we have:

L = ∫√(1 + (-tan(x))²) dx

= ∫√(1 + tan²(x)) dx

= ∫√(sec²(x)) dx

= ∫sec(x) dx

= ln|sec(x) + tan(x)| + C,

where C is the constant of integration.

Applying the limits -4π and 4π to the integral, we get:

L = ln|sec(4π) + tan(4π)| - ln|sec(-4π) + tan(-4π)|.

Simplifying, sec(4π) = 1 and tan(4π) = 0, and sec(-4π) = 1 and tan(-4π) = 0. Therefore, the expression reduces to:

L = ln(1) - ln(1) = 0.

Hence, the length of the curve y = ln(cos(x)) for -4π ≤ x ≤ 4π is 16π.

The difference between an actual score and a predicted score is called a residual.

In various fields such as statistics, econometrics, and data analysis, the term "residual" refers to the difference between the observed or actual value of a variable and the value predicted by a model or estimation method. It represents the unexplained or leftover variation in the data after considering the model's predictions.

In the context of regression analysis, the predicted score is obtained by fitting a regression model to the data and using it to estimate the expected value of the dependent variable. The difference between the actual value and the predicted value for a specific observation is the residual for that observation.

Residuals play a crucial role in assessing the goodness of fit of a regression model. By examining the pattern and properties of residuals, such as their mean, variance, and distribution, analysts can evaluate how well the model captures the underlying relationships in the data and identify any systematic deviations or outliers.

Overall, residuals provide valuable information for understanding the accuracy and precision of predictions made by a model and can be used to refine and improve the model's performance.

The price per T-shirt should be at least $15 to achieve a profit of $250.

To calculate the price per T-shirt that will yield a profit of at least $250, we need to consider the cost of production, the desired profit, and the number of shirts to be sold.

Given that the cost to make each T-shirt is $10, and we want to sell 50 shirts, the total cost of production would be 10 * 50 = $500.

Now, let's calculate the minimum revenue needed to achieve a profit of $250. We add the desired profit to the total cost of production: $500 + $250 = $750.

Finally, to determine the price per T-shirt, we divide the total revenue by the number of shirts: $750 ÷ 50 = $15.

Therefore, to make a profit of at least $250, the price per T-shirt should be set at $15.

By selling each T-shirt for $15, the total revenue would be $15 * 50 = $750. From this revenue, we subtract the total production cost of $500 to calculate the profit, which amounts to $750 - $500 = $250. Thus, by charging $15 per T-shirt, the desired profit of $250 is achieved.

(x - 1)(5x - 6)

Step-by-step explanation:

Given

5x² - 11x + 6

Consider the factors of the product of the coefficient of the x² term and the constant term (ac) which sum to give the coefficient of the x- term (b)

ac = 5 × 6 = 30 and b = - 11

The factors are - 5 and - 6

Use these factors to split the x- term

5x² - 5x - 6x + 6 ( factor the first/second and third/fourth terms )

= 5x(x - 1) - 6(x - 1) ← factor out (x - 1) from each term

= (x - 1)(5x - 6)

Some strategies to find a relationship between x and y include plotting a scatter plot, calculating correlation coefficient, performing regression analysis, conducting hypothesis testing, using machine learning algorithms, and analyzing historical data.

To explore the relationship between x and y, one effective strategy is to plot a scatter plot. This visual representation allows us to observe the distribution of data points and identify any patterns or trends. Additionally, calculating the correlation coefficient can help quantify the strength and direction of the relationship. A positive correlation indicates that as x increases, y also tends to increase, while a negative correlation suggests an inverse relationship. Regression analysis can further establish a mathematical equation that describes the relationship between x and y, enabling predictions or estimations based on the given data.

Hypothesis testing allows for statistical inference, determining if the relationship between x and y is statistically significant. Machine learning algorithms can be employed to analyze the data and identify complex relationships, especially in large datasets. Finally, analyzing historical data can provide insights into how x and y have interacted in the past, which may inform the understanding of their relationship in the present context.
