As part of a study on the effect of forest fragmentation on the decline of the songbird population, a team of researchers needs to gather information on the nest predation. A large forest area is divided up into N = 80 (nonoverlapping) sites, each of approximately the same size. Due to time and cost constraints, the researchers would like to select five of these sites at random and send out one team of researchers to each site for observation. You are to select a simple random sample of size n = 5 from a population of 80 sites. Explain how you would label the sites and how you would use random integer on the TI calculator. Using a seed value of 29, identify the 5 sites that would be selected from the 80 sites in the forest.

Step-by-step explanation:

26×12 = 312

partial products are "strange". but ok, since your teacher wants it that way :

multiply the tens with the tens : 20×10 = 200

multiply the tens with the ones : 20×2 = 40

multiply the ones with the tens : 6×10 = 60

multiply the ones with the ones : 6×2 = 12

--------

312

so, 12 and 40 are correct from the original list, 600 and 2000 are wrong.

how do you do it conceptually ?

26×12 start with the left digit (1),

multiply the left number right to left

6×1 (no carry) 6

2×1 2

26

next digit to the right (2),

also move the result one position

6×2 (carry 1) 2

2×2 (plus carry) 5

52

now we add position related

---------

The significance level is set at 5% and the probability of the result is 3.6% which is less than the significance level. The result is statistically significant

Probability simply means the chance that a particular thing or event will happen. It is the occurence of likely events. It is simply the area of mathematics that deals with the numerical estimates of the chance that an event will occur or that a particular statement is true

The probability of the treatment group’s mean being greater than the control group’s mean by 8 points or more will be:

= (26 + 8 + 2)/1000

= 36/1000

= 0.036

Answer:

The correct answers are \(x < 9\) and any rational number less than 9.

Step-by-step explanation:

Since the inequality represented in the number line has the arrow going towards the left, and has a open/not highlighted circle on 9, that means the inequality represented by the number line is \(x < 9\), which means the exact same as any rational number less than 9, so those two choices are the correct answer.

Answer: I'll give you both the percentage and dollar amount. 75% = $144

Step-by-step explanation: first, I added up all the percentages to total 75%. then I took the total sales, and divided that by .75 (75% in decimal form), so:

1940 x .75 = 1455

1940 - 1455 = 144

First, we know that the slope of a perpendicular line given the equation of the line it is perpendicular can be found using the following equation:

in this case, we have the line y = x + 3. Then, we have that its slope is m = 1, then, the perpendicular slope is:

now that we have the slope of the perpendicular line, we can use the point (-4,5) and the slope-point formula to get:

therefore, the equation of the line perpendicular to y = x+3 and passes through the point (-4,5) is y = -x + 1

Procedures that help organize or describe data collected from a sample or a population are called Descriptive statistics.

Hence, option D is correct answer.

Data can be meaningfully and effectively described or summarised using descriptive statistics. For instance, knowing that everyone in our scenario wore blue shoes wouldn't be helpful. It would be helpful to know how evenly distributed their anxiety scores were. Measures of central tendency and measurements of variability make up descriptive statistics (spread).

The mean, median, and mode are measurements of central tendency, while the standard deviation, variance, minimum and maximum variables, kurtosis, and skewness are measures of variability.

In order to emphasise potential correlations between variables and to give basic information about the variables in a dataset, descriptive statistics can be helpful for both of these aims.

The Venn diagram for (D ⋃ E) ⋃ F will be the ovarlapped region of D,E and F.

To represent the sets D, E, and F in the Venn diagram, we first construct three overlapping circles. Then, beginning with the innermost operation and moving outward, we shade the regions corresponding to the set operations in the expression.

We shade the area where the circles for D and E overlap because the equation (D ⋃ E)  denotes the union of the sets D and E. All the elements in D, E, or both are represented by this area.

The union of (D ⋃ E) with F is the next step. This indicates that we darken the area where the circle for F crosses over into the area that we shaded earlier. All the components found in sets D, E, F, or any combination of these sets are represented in this region.

The final Venn diagram should include three overlapping circles, with (D ⋃ E) ⋃ F shaded in the area where all three circles overlap.

The values of x and y are in the triangles are (28) x = 90√3 and y = 90 and (29) x = 116 and y = 58

Triangle 28

The value of x is calculated using the following cosine function

cos(30) = Adjacent/Hypotenuse

So, we have

cos(30) = x/180

Multiply through by 180

So, we have

x = 180 * cos(30)

Evaluate cos(30)

x = 180 * √3/2

Evaluate the product

x = 90√3

The value of y is calculated using the following sine function

sin(30) = Opposite/Hypotenuse

So, we have

sin(30) = y/180

Multiply through by 180

So, we have

y = 180 * sin(30)

Evaluate sin(30)

y = 180 * 1/2

Evaluate the product

y = 90

Hence, the values of x and y are x = 90√3 and y = 90

Triangle 29

The value of x is calculated using the following sine function

sin(60) = Opposite/Hypotenuse

So, we have

sin(60) = 58√3/x

Multiply through by x

So, we have

x  sin(60) = 58√3

This gives

x = 58√3/sin(60)

Evaluate sin(60)

x = 58√3/(√3/2)

Evaluate the quotient

x = 116

The value of y is calculated using the following cosine function

cos(60) = Adjacent/Hypotenuse

So, we have

cos(60) = y/x

cos(60) = y/116

Multiply through by 116

So, we have

y = 116 * cos(60)

Evaluate cos(60)

y = 116 *1/2

Evaluate the product

y = 58

Hence, the values of x and y are x = 116 and y = 58

Step-by-step explanation:

Yes, Matrix B is invertible.

And, The eigenvalues of B−1 are;

⇒ (5 ± 7.68) / 14 - 1

An Invertible Matrix is a square matrix defined as invertible if the product of the matrix and its inverse is the identity matrix.

Given that;

B be a 2 ×2 matrix such that;

⇒ 7B² −5B + 3I = 0

Now,

Since, B be a 2 ×2 matrix.

And, The expression is,

⇒ 7B² −5B + 3I = 0

⇒ B² −5/7B + 3I/7 = 0

Multiply by B⁻¹, we get;

⇒ B - 5/7 + 3B⁻¹ = 0

Solve for B⁻¹;

⇒ 3B⁻¹ = - B + 5/7

⇒ B⁻¹ = - B/3 + 5/21

Thus, The matrix B is invertible.

And, The eigen value of B are;

⇒ 7B² −5B + 3I = 0

⇒ 7B² −5B + 3I = 0

⇒ B = - (-5) ± √(-5)² - 4×7×3 / 2×7

⇒ B = 5 ± √25 - 84/14

⇒ B = 5 ± √- 59 / 14

⇒ B = 5 ± 7.68 i / 14

⇒ B - 1 = (5 ± 7.68) / 14 - 1

Thus, Matrix B is invertible.

The eigenvalues of B−1 are = (5 ± 7.68) / 14 - 1

Given the equations a × b = 5742 × 6368, a × c = 5748 × 6362, and c × b = 5738 × 6372, we need to determine the relationship between the three variables a, b, and c.

By comparing the given equations, we notice that the numbers on the right-hand side of each equation are very close to each other, differing only by small amounts. This suggests that a, b, and c are approximately equal.Since a × b, a × c, and c × b involve the same numbers with slight variations, we can conclude that a, b, and c are all very close in value.

Therefore, the inequality we can infer from this information is a ≈ b ≈ c, indicating that a, b, and c are approximately equal.

In simple terms, based on the given equations, it suggests that the values of a, b, and c are very similar or approximately equal to each other.

2/3 probability

Step-by-step explanation:

less than 5 is 4. There are 6 sides, so its 4/6. 4 out of 6 simplifies to 2/3.

Answer:

as there are 2 six-sided dices so total cases = 6*6 = 36

products less than 5 are = (1,1) , (1, 2), (1, 3), (2,1), (2,2), (3,1)

so number of products less than 5 = 6

To evaluate the expression (2b+3a)×(c^2) when a=4, b=3, and c=1/3, we substitute the given values into the expression and perform the indicated arithmetic operations:

(2b + 3a) × (c^2)

= (2(3) + 3(4)) × ((1/3)^2) (substitute a=4, b=3, c=1/3)

= (6 + 12) × (1/9) (evaluate 2(3) + 3(4) and (1/3)^2)

= 18/9

= 2

Therefore, when a=4, b=3, and c=1/3, the expression (2b+3a)×(c^2) equals 2.
