If a1=6 and an=an-1 -2

If D and R are independent, then P(D or R) = 0.8412

Two events are independent if the occurrence of one event does not affect the chances of the occurrence of the other event. The mathematical formulation of the independence of events A and B is the probability of the occurrence of both A and B being equal to the product of the probabilities of A and B (i.e., P(A and B)

P(D) = 0.26 and P( R) = 0.26 , if D and R are independent, then,

P(D or R) = P(D) + P(R) - P(DnR)

then P(DnR) = P(D) × P(R) = 0.26×0.38 = 0.0988

P(D or R) = 0.26+0.38-0.0988

= 0.8412

Therefore the probability of P(D or R) if D and R are independent is 0.8412

The solution for the given inequality is, (-∞, -5] ∪ [-1, ∞).

What is inequality?

In mathematics, inequalities describe the relationship between two values that are not equal. Equal means to be equal, not. The "not equal symbol (≠)" is typically used to indicate that two values are not equal. But different inequalities are used to compare the values to determine whether they are less than or greater than.

Consider, the given inequality

|x + 3| - 2 ≥ 0

⇒ |x + 3| ≥ 2

Using: If |u| ≥ a,  a > 0 then u ≤ -a, u ≥ a

⇒  x + 3 ≤ -2,    x + 3 ≥ 2

x ≤ -5,      x ≥ -1

Hence, the solution for the given inequality is, (-∞, -5] ∪ [-1, ∞).

Answer:

El banco recibió 128 rollos de monedas de 10 centavos.

Step-by-step explanation:

Para saber cuantos rollos de monedas de 10 centavos recibió el banco, podemos dividir el total de monedas recibido entre el número de monedas por rollo.

(1 024 monedas) / (8 monedas/rollo) = (x rollos)

Donde x es el número de rollos recibido. Para calcular x se divide 1 024 entre 8

x = 1 024 / 8

x = 128

The principal of the bond can be calculated using the formula Principal = Interest / Rate x Time. In this case, the interest is $3,875, the rate is 7.75%, and the time is 25 years. Therefore, the principal of the bond is: Principal = $3,875 / 0.0775 x 25 = $20,000.

Step-by-step explanation:

The principal of the bond can be calculated using the formula Principal = Interest / (Rate x Time), where Interest, Rate and Time are given in the problem statement.

By using this formula, the principal of the bond is $20,000. This is the amount of money that was invested to earn the interest of $3,875 over 25 years with the interest rate of 7.75%.

Step-by-step explanation:

This is a quadratic function, which is a function of the form f(x) = ax^2 + bx + c, where a, b and c are constants. The function can be written in general form as f(x) = (x-4) / (x^2 +13x + 36).

To find the roots of the function (i.e. the points at which the function intersects the x-axis), we can use the quadratic formula:

x = [-b +/- sqrt(b^2 - 4ac)] / 2a

In this case, a = 1, b = 13 and c = 36.

Substituting these values into the quadratic formula, we get:

x = [-13 +/- sqrt(169 - 4(1)(36))] / 2

x = [-13 +/- sqrt(97)] / 2

x = [-13 +/- 9.8488578] / 2

x1 = -1.1744289

x2 = 11.1744289

Therefore, the roots of the function are x1 = -1.1744289 and x2 = 11.1744289.

Answer:

y = 5x - 4

Step-by-step explanation:

1. Parallel have the same slope (equation)

- Standard form of an equation of a line: y=mx + b

m = slope

x = x-coordinate

b = y-intercept

y = y-coordinate

SLOPE = [tex]\frac{y_{2} -y_{1} }{x_{2}-x_{1}}[/tex]

Given that x-2y = 5

and the line has the point:

(-3,-1)

We need to find another point to find the slope

x - 2y = 5

Let's say x = 7 and y = 1

(7, 1)

Now plug it into the slope equation

[tex]\frac{-3-7}{-1-1} = \frac{-10}{-2} = 5[/tex]

Plug the slope into the standard form of an equation of a line

y = 5x + b

Plug in (7,1)

1 = 5 + b

b = -4

The answer is: y = 5x - 4

Thandi's statement that 20% of Alaskan totem poles featured in the book have eagles carved in them is not accurate.

A two-way table, also known as a contingency table, is used to organize and display the relationship between two categorical variables. The table shows the frequency or count of observations for each combination of the two variables. In this case, the two variables are the animals carved in the totem poles and the regions where the totem poles are located.

To find the percentage of Alaskan totem poles that have eagles carved in them, we need to divide the number of Alaskan totem poles with eagles by the total number of Alaskan totem poles and multiply by 100. This can be calculated as:

(Number of Alaskan totem poles with eagles / Total number of Alaskan totem poles) * 100

Without the data for the two-way table it's impossible to check if the statement is correct or not. It's important to note that without the data it is also impossible to know the context of the statement and the information provided in the book.

In Mathematics, a bar chart (bar graph) simply refers to a type of chart that is used for the graphical representation of a population (data set), especially through the use of rectangular bars and vertical columns.

Based on the given bar chart which represents people's test scores in English and French, we can reasonably infer and logically deduce that table showed that Eleanor scored 12 in her English test while it was recorded as 14 on the bar chart.

Similarly, the table showed that Georgia scored 18 in her English test while it was recorded as 15 on the bar chart.

The difference between the functions G(x) and h(x) is 4 units.

The function is defined as a mathematical expression that defines a relationship between one variable and another variable.

The functions are given in the question, as follows:

G(x)=-f(x)+10 and h(x)=-f(x-4)+10

Since the functions, g and h differ

This can be seen by subtracting G(x) from h(x):

h(x) - G(x) = (-f(x-4) + 10) - (-f(x) + 10)

h(x) - G(x) = 4.

This means that for any value of x, the output of h(x) will be 4 units greater than the output of G(x).

Set an inequality:

Answer:

131.25 feet.

Step-by-step explanation:

We can use the concept of similar triangles to find the length of the monument's shadow.

Since the pole and the monument are casting the shadows, we can assume that the ratio of the height of the pole to the length of its shadow is equal to the ratio of the height of the monument to the length of its shadow.

12/5 = 315/x

Where x is the length of the monument's shadow.

We can cross-multiply and solve for x:

12x = 5315

x = 5*315/12

x = 131.25

So, the length of the monument's shadow is approximately 131.25 feet.
