The estimated deer population live in the region is calculated as:

N = (2 * 220 * 50) / x

One method to estimate the deer population is by using the Lincoln-Petersen index, which is calculated as:

N = (2 * tagged deer count * sample size) / (number of tagged deer in the sample).

Using the data you provided, the number of tagged deer in the 8 samples is the sum of all the tagged deer counted in each sample, let's call this sum "x". Then, the estimated deer population in the region is calculated as:

N = (2 * 220 * 50) / x

Since the actual value of x is unknown, we cannot calculate the exact population. But, this formula gives us a method to estimate the population based on the number of tagged deer found in future samples.

Answer:

0.543 or 54.3%

Step-by-step explanation:

This is an example of a binomial distribution, where the probability of success (playing the particular song) is 0.42, and the number of trials is 6.

To find the probability that the song will be played on at least 3 days out of 6, we need to calculate the probability of the song being played on 3, 4, 5, or 6 days.

Using a binomial probability calculator or formula, we can calculate these individual probabilities:

Probability of the song being played on 3 days out of 6: 0.308

Probability of the song being played on 4 days out of 6: 0.177

Probability of the song being played on 5 days out of 6: 0.052

Probability of the song being played on all 6 days: 0.006

To get the probability of the song being played on at least 3 days out of 6, we add these individual probabilities together:

0.308 + 0.177 + 0.052 + 0.006 = 0.543

Therefore, the probability that the song will be played on at least 3 days out of 6 is 0.543 or 54.3% (rounded to the nearest thousandth).

x = original price for the jacket

now, let's reduce it by 20%, so hmmm that means the new price is really 100% - 20% = 80% of the original price, how much is that?

[tex]\begin{array}{|c|ll} \cline{1-1} \textit{\textit{\LARGE a}\% of \textit{\LARGE b}}\\ \cline{1-1} \\ \left( \cfrac{\textit{\LARGE a}}{100} \right)\cdot \textit{\LARGE b} \\\\ \cline{1-1} \end{array}~\hspace{5em}\stackrel{\textit{80\% of x}}{\left( \cfrac{80}{100} \right)x}\implies 0.8x[/tex]

now, from that new price, let's reduce it by 10%, that means the newer price will be 100% - 10% = 90% of this new price of 0.8x, so

[tex]\stackrel{\textit{90\% of 0.8x}}{\left( \cfrac{90}{100} \right)0.8x}\implies 0.72x\hspace{5em}\stackrel{\textit{72\% of the orignal price}}{\textit{a reduction of 28\%}}[/tex]

Small Side: 3 x 5 = 15

Answer:

The area of a rectangle with length 4 cm and width 6 cm is 24 square cm. To find the area of a semi-circle, we use the formula for the area of a circle and divide by 2. The formula for the area of a circle is πr^2, where r is the radius. The radius of the semi-circle is half the width of the rectangle, so r = 6/2 = 3 cm. Thus, the area of the semi-circle is π(3^2) = 9π square cm.

The total area of the figure would be the sum of the area of the rectangle and the semi-circle, so the answer would be 24 + 9π square cm.

The number with a subscript of 12 or number base 12 that is equal to 888₉ + 555₆ + 222₂ is 689.

Using the number base conversion system,  the sum of the given numbers in base ten is determined as follows:

888₉ + 555₆ + 222₂ = X₁₂

888₉ = 8 * 9² + 8 * 9¹ + 8 * 9⁰

888₉ = 728

555₆ = 5 * 6² + 5 * 6¹+ 5 * 6⁰

555₆ = 215

222₃ = 2 * 3² + 2 * 3¹ + 2 * 3⁰

222₃ = 26

888₉ + 555₆ + 222₂ = 728 + 215 + 26

888₉ + 555₆ + 222₂ = 969

Answer:

Step-by-step explanation:

480 total

1/2 = 240 are cows

1/8 = 60 are goats

remaining = 480-240-60 = 180 are chickens & ducks

33.3333% of 180 = chickens  =180/3 = 60 chickens

so ducks = 180-60 =120

Answer:

120

Step-by-step explanation:

given that out of 480 animals 0.5 of the animals are cows . So ,

no. of cows = 0.5*480 = 240

Again, we are given that 1/8 of the animals are goats , so the number of goats would be ,

no. of goats = 1/8*480 = 60

Total no. of goats and cows ,

= 240 + 60 = 300

No. of remaining animals= 480 -300 = 180

Now out of these 180 animals 33⅓ % animals are chickens and remaining are ducks.

Percentage of ducks = (100 - 33⅓ )% = 66.67%

So the number of ducks would be ,

180 * 66.67/100 = 120

2425÷ 45 can be solved by using long division. The first step is to divide the first number (2425) by the divisor (45). The result, 54, is the first number in the answer.

What does math's long division mean?

The mathematical operation of breaking up huge numbers into several smaller groups or sections is known as long division. The number we divide by is known as the divisor, and the number we divide into smaller groups is known as the dividend. A problem can be handled by breaking it down into smaller, more manageable parts.

Next, subtract 54 x 45 (2430) from 2425, which leaves a remainder of -5.

To continue long division, we bring down the next number in the dividend (2425), which is a 5. Next, divide the remainder (-5) by the divisor (45). The result, -1/9, is the second number in the answer.

Finally, subtract -1/9 x 45 (-5) from the remainder (-5), which leaves a remainder of 0. The answer is 54 1/9.

Descriptive statistics is a branch of statistics that are used to characterize the features of a sample by using quantitative techniques.  

Descriptive statistics can help to provide simple descriptions of the observations by using measures of Central Tendency like mean, variance, median, charts, etc...  

Data with one variable are described using univariate descriptive statistics. On the other hand, data with several variables are described using bivariate and multivariate descriptive statistics.  

The two categories of descriptive statistics are Measures of central tendency and measures of dispersion, which are used to summarize the characteristics of grouped and ungrouped data.  

Measures of central tendency are Mean, Median, and Mode, where Measures of Dispersion are Range, Variance, Standard Deviation, Mean Deviation, etc.

Here we have

A mathematical equation is a formula that joins two statements and uses the equal symbol (=) to indicate equality. A mathematical statement that establishes the equality of two mathematical expressions is known as an equation in algebra. For instance, in the equation 3x + 5 = 14, the equal sign places the variables 3x + 5 and 14 apart. The relationship between the two sentences on either side of a letter is described by a mathematical formula. Often, there is only one variable, which also serves as the symbol. for instance, 2x – 4 = 2.

explanation: In order to find what two numbers have a Product and Sum write down what you know initially.

Let's assume the values we need to find are x, y whose product and sum are known.

Write the given data in the form of equations.

By using basic substitution, you will get an expression from which you can find the values easily.

If you aren't sure whether the results arrived are accurate or not cross-check the results obtained in the equations framed with input data.

Sum of two numbers = 24

Let's consider the numbers we need to find as x and y

To solve the problem x.y = 44

x+y = 24

y=24-x

Replace the value of y in the equation x.y=44. It's not necessarily y if you want you can interchange with the value of x too as x and y are interchangeable. . (24-x)=44

On solving the equation we get two numbers as 2 and 22

That's it the two numbers whose product is 44 and the sum is 24 are 2, 22. so you should be able to do the same with your question hope that helps!

The statements that are true are:

The x-coordinate of the solution is 1.

The y-coordinate of the solution is -1.

The solution to a system of equations that is graphed is the point at which the two lines intersect. The coordinates of the intersection point are the solution to the system of equations.

In other words, if we have two lines represented by two linear equations, the solution to the system of equations is the point where the two lines intersect. This point is unique and it satisfies both equations simultaneously.

Therefore, the graph shows that both lines intercept at (1, -1). Therefore, the statements that will be true are:
