The length of BD in the triangle is 24 units.

The triangles are similar by angle bisector theorem. The angle bisector theorem states that the angle bisector of an angle of a triangle divides the opposite side into two parts that are proportional to the other two sides of the triangle.

Therefore, let's find BD.

Hence, using the proportion,

12  / 20 = x / x + 6

cross multiply

12(x + 6) = 20x

12x + 72 = 20x

72 = 20x - 12x

72 = 8x

divide both sides by 8

x = 72  /8

x = 9

Therefore,

BD = x + x + 6 = 2x + 6

BD = 2(9) + 6

BD = 18 + 6

BD = 24 units

The population of the rabbit in the year 2002 will be 940 rabbits.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Now,

The exponential model consisted the expression;

\(y = A r^{t}\)

Where, A is initial population and r is increase rate and t is time.

So, The initial population and increase rate for the given condition are;

\(740 = A . r^{0} \\\\A = 740\)

And,

\(870 = 740 * r^{7}\)

\(r^{7} = \frac{870}{740}\)

\(r^{7} = \frac{87}{74}\)

r = 1.89/1.84

r = 1.02

So, The exponential  model consisted the expression;

\(y = A r^{t}\)

\(y = 740 r^{12}\)

\(y = 740 * (1.02)^1^2\)

\(y = 740 * 1.27\)

\(y = 939.8\)

Therefore,

The population of the rabbit in the year 2002 will be 940 rabbits.

Angle A = 62°, Length AC = 12cmIn order to find the length of AB, we will be using the trigonometric ratio.

i.e., Tan since the opposite and adjacent sides are given:tan A = Opposite / Adjacenttan

A = AB / AC

tan 62° = AB / 12

AB = 12 x tan 62°

AB ≈ 23.69

Therefore, the length of AB is approximately equal to 23.69cm (to 1 decimal place).Hence, Thus, the length of AB is approximately equal to 23.69cm (to 1 decimal place).

Step-by-step explanation: When I graphed the equation and went to -1 y, the answer was -4.

The net income for Griffin's Goat Farm, Inc., was \(\$184,340\).

The operating cash flow (OCF) for Kerber's Tennis Shop, we can use the following formula:

\(OCF = EBIT + Depreciation - Taxes + \triangle Working Capital\)

where EBIT is earnings before interest and taxes.

Calculate EBIT by subtracting interest expense from operating income:

EBIT = Operating Income - Interest Expense

We do not have the information for operating income, but we can use the fact that interest expense was. \(\$165,000\) to calculate EBIT.

EBIT = Interest Expense / (1 - Tax Rate)

= \(\$165,000 / (1 - 0)\)

= \(\$165,000\)

Calculate the change in working capital (Δ Working Capital). We are told that the company reduced its net working capital investment by \(\$69,000\), which means that working capital increased by  \(\$69,000\).

Therefore:

\(\triangle Working Capital = \$69,000\)

Now, we can calculate OCF:

OCF = EBIT + Depreciation - Taxes + Δ Working Capital

=\(\$165,000 + 0 - 0 +\ $69,000\)

=\(\$234,000\)

Therefore, the firm’s 2018 operating cash flow (OCF) was \(\$234,000\) .

To calculate the net income for Griffin's Goat Farm, we can use the following formula:

Net Income = EBIT - Interest Expense - Taxes

where EBIT is earnings before interest and taxes. We can calculate EBIT as:

EBIT = Sales - Costs - Depreciation

= \(\$686,000 - \$332,000 - \$65,000\)

=\(\$289,000\)

Next, we need to calculate taxes. We are given a tax rate of 24%, so:

Taxes = Tax Rate x (EBIT - Depreciation)

= \(0.24 \times (\$289,000 - \$65,000)= \$56,160\)

Now, we can calculate net income:

Net Income = EBIT - Interest Expense - Taxes

= \(\$289,000 - \$48,500 - \$56,160= \$184,340\)

A student's probability of having a sister are 1/2 or 0.5 if they do not have a brother.

Using the above data table, we must determine the likelihood that a student without a brother also has a sister. Analysing the table now

has a sibling: 5

possesses no sisters: 2

has an 18-year-old brother

possesses no brothers: 4

We are looking for the likelihood that a student has a sister and neither a brother (as indicated by the statement "Does not have a brother"). In this instance, there are two children who do not have a brother but do have a sister, making that number the number of positive outcomes.

No matter whether a student has a sister or not, the total number of outcomes is equal to the number of students who do not have a brother. According to the table, there are 4 students without brothers.

As a result, the likelihood that a student who doesn't have a brother will have a sister can be determined as follows:

Probability is calculated as the ratio of the number of favourable outcomes to all possible outcomes.

Options

\((A)\left(-\infty , \dfrac23\right]\\\\(B)\left(-\infty , \dfrac23\right) \\\\(C)(\frac23\right, \infty ) \\\\(D) [\frac23\right, \infty )\)

Answer:

\((C)(\frac23\right, \infty )\)

Step-by-step explanation:

Given the solution to an inequality

{x|x>2/3}

The solution set does not include \(\dfrac23\) , therefore, it must be open at the left. Recall that we use a curvy bracket ( to denote openness at the left.

Since x is greater than  \(\dfrac23\) , the solution set contains all values of larger than  \(\dfrac23\) up till infinity. Since infinity is an arbitrarily large value, we also use an open bracket at the right.

Therefore, another way to represent the solution {x|x>2/3} is:

\((\frac23\right, \infty )\)

The correct option is C.

If you need to find the remainder when a polynomial \(f(x)\) is divided by \(x-a\), you can compute \(f(a)\) on your calculator.

Use a scientific calculator and type the polynomials and use the divide option to find the remainder theorem.

What is remainder theorem?

The remainder theorem states that when a linear polynomial q(x) with a zero of x = a divides a polynomial p(x) (whose degree is greater than or equal to 1), the remainder is given by r = p. (a).

Without actually doing the long division steps, one may use the remainder theorem to calculate the remainder of the division of any polynomial by a linear polynomial.

The remainder theorem calculator should be used as follows:

Step 1: Type the polynomials for the numerator and denominator in the appropriate input fields.

Step 2: To receive the output, now select "Divide" from the menu.

Step 3: Lastly, the remainder and quotient will be shown in the new

In a bimodal histogram, the two highest bars will have the same height.

The above statement is TRUE that is n a bimodal histogram, the two highest bars will have the same height.

A histogram is said to be bimodal if it has two peaks. The only defining characteristic about this distribution is that it has 2 peaks of the same height. Bimodality sometimes occurs when the data set consists of observations from two different group of individuals. If this shape occurs, the two sources should be separated and analysed separately.

A bimodal histogram shape often reflects the presence of two different processes being "mixed" in the displayed data. For example, the data could contain information from two different machines, two shifts, weekdays and weekends, two offices, etc.

In some cases bimodal histogram indicates that the sample can be divided into two sub samples that differ from each other in some way.

Thus in a bimodal histogram, the two highest bars will have the same height.
