The data presented shows the growth of the Javanese gibbon population on three different islands over time.

Data trends must be analyzed to determine the type of function that is modeling population growth. A common way to do this is to plot the data points and observe the shape of the curve. However, since the table only contains data, you can analyze trends by looking at the differences between consecutive terms.

To do this, we can calculate the first difference and the second difference in the population data.

The first difference:

- Swing: 40 - 30 = 10, 50 - 40 = 10, 60 - 50 = 10

Example: 60 - 50 = 10, 75 - 60 = 15, 90 - 75 = 15

- Salavati: 80 - 60 = 20, 100 - 80 = 20, 120 - 100 = 20

The second difference:

- Batanta: 10 - 10 = 0, 10 - 10 = 0

- Example: 15 - 10 = 5, 15 - 15 = 0

- Salavati: 20 - 20 = 0, 20 - 20 = 0

The first difference is constant for each island and shows a linear relationship between time and population growth. Also, the second difference is zero, indicating a constant rate of change.

Therefore, we can conclude that the population growth modeling function is a linear function that can be written as

M(x) = mx + b

where x is the time in years, m is the slope (population growth rate), and b is the y-intercept (initial population).

The probability that the randomly selected point is in the bullseye = 15/16.

To calculate the probability that the randomly selected point is in the bullseye, we shall first evaluate the area of each of the circles:

The area of the larger circle (outer circle) with radius 8 cm is given:

A_outer = πr² = π(8)² = 64π

The area of the smaller circle (inner circle) with radius 2 cm is given:

A_inner = πr² = π(2)² = 4π

The area of the bullseye (the region between the two circles) = the difference between the areas of the two circles:

A_bullseye = A_outer - A_inner

= 64π - 4π = 60π

Therefore, the probability that a randomly selected point is in the bullseye:

P = A_bullseye / A_outer

= (60π) / (64π)

P = 15/16

x² + 5x + 3 = 0, the quadratic equation has two distinct real roots

2x² - 2x + 1 = 0, no real roots. Instead, it has two complex conjugate roots.

x² + 5x + 3 = 0

To determine the nature of the roots of this quadratic equation, we need to calculate the discriminant using the formula:

Discriminant = b² - 4ac

where a, b, and c are the coefficients of the quadratic equation ax^2 + bx + c = 0.

In this case, a = 1, b = 5, and c = 3.

Discriminant = (5)² - 4(1)(3)

= 25 - 12

= 13

Since the discriminant is positive and not a perfect square, the quadratic equation has two distinct real roots

Now 2x² - 2x + 1 = 0

a = 2, b = -2, and c = 1

Plugging these values into the discriminant formula, we get:

b²  - 4ac = (-2)²  - 4(2)(1) = 4 - 8 = -4

Since the discriminant is negative, the quadratic equation 2x² -2x+1=0 has no real roots.

Step-by-step explanation:

We want to show that sinθ cosθ = cotθ is not true for all values of θ. To do this, we just need to find one counterexample, i.e., one value of θ for which the equation is not true.

Recall that cotθ = cosθ/sinθ. So, the equation sinθ cosθ = cotθ can be rewritten as sinθ cosθ = cosθ/sinθ.

Multiplying both sides by sinθ, we get:

sin^2θ cosθ = cosθ

Dividing both sides by cosθ, we get:

sin^2θ = 1

Taking the square root of both sides, we get:

sinθ = ±1

So, we need to find a value of θ such that sinθ is equal to ±1. This occurs when θ = π/2 + kπ, where k is an integer.

Now, let's check whether sinθ cosθ = cotθ is true for this value of θ. We have:

sin(π/2 + kπ) = ±1

cos(π/2 + kπ) = 0

cot(π/2 + kπ) = undefined (since cos(π/2 + kπ) = 0)

Therefore, sinθ cosθ = cotθ is not true for θ = π/2 + kπ, and we have found a counterexample. This shows that sinθ cosθ = cotθ is not a trigonometric identity.

The surface area of each square pyramid, we used the formula Surface Area = Base Area + 4 x (1/2 x Base x Height of Face) is 1049.2mm², 1285.8mm² and 2100mm². The cost to cover each pyramid was $1.05, $1.29 and $2.10.

To calculate the surface area of each pyramid, we need to use the formula

Surface Area = Base x Height of face + 2 x ((Base/2) x Slant Height)

For the small pyramid, we have

Surface Area = 20 x 25 + 2 x ((20/2) x 26.46)

Surface Area = 500 + 2 x 10 x 26.46

Surface Area = 1049.2 mm²

Cost to cover the small pyramid

Cost = Surface Area x 0.001

Cost = 1049.2 x 0.001

Cost = $1.05

For the medium pyramid, we have

Surface Area = 20 x 40 + 2 x ((20/2) x 42.43)

Surface Area = 800 + 2 x 10 x 42.43

Surface Area = 1285.8 mm²

Answer:

Step-by-step explanation:The six sample minimums are 15, 15, 15, 18, 18, and 20.

To find the mean of all six sample minimums, we add them up and divide by 6:

(15 + 15 + 15 + 18 + 18 + 20) / 6 = 16.1667

So the mean of all six sample minimums is $16,166.67.

The population minimum is the smallest cost among the four cars, which is $15,000.

The sample minimum is a biased estimator of the population minimum. Since the samples are of size 2, the probability of obtaining the population minimum as the sample minimum is only 1/3 (when the minimum of the two cars selected is the population minimum). Therefore, the sample minimum tends to underestimate the population minimum.

The original sample box had a volume of 343 cubic cm, which is half the volume of the new sample box.

Since the height of the new sample box is twice as long as the original box, its height will be 2×7=14 cm.

The length and width remain the same at 7 cm.

The volume of the new sample box is given by the formula:

V = lwh

Substituting the values, we get:

V = (7)(7)(14) = 686 cubic cm

Therefore, the volume of the new sample box is 686 cubic cm.

Comparing the volumes of the two boxes, we see that the new sample box has a larger volume than the original sample box.

Step-by-step explanation:

The area of the shaded region of a circle with a 100 degree angle and a radius of 3cm, using pi=3.14, is approximately 25.64 square centimeters.

To find the area of the shaded region of a circle, we need to subtract the area of the sector formed by the shaded region from the area of the whole circle.

The area of the whole circle is given by

A = πr²

where A is the area of the circle, r is the radius of the circle, and π is a mathematical constant approximately equal to 3.14 (as given in the question).

Substituting the given values, we get

A = π(3cm)²

A = 28.26 cm² (rounded to two decimal places)

Now, let's find the area of the sector formed by the shaded region.

The angle of the sector is given as 100 degrees. To find the area of the sector, we need to use the formula:

A = (θ/360)πr²

where θ is the angle in degrees, r is the radius of the circle, and π is again approximately equal to 3.14.

Substituting the given values, we get

A = (100/360)π(3cm)²

A = 2.62 cm² (rounded to two decimal places)

Finally, we can find the area of the shaded region by subtracting the area of the sector from the area of the whole circle

Shaded area = Area of circle - Area of sector

Shaded area = 28.26 cm² - 2.62 cm²

Shaded area = 25.64 cm² (rounded to two decimal places)

Therefore, the area of the shaded region of the circle is approximately 25.64 square centimeters.
