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).

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

To find the points that satisfy the equation y = -3 - x, we can substitute different values of x and solve for y.

When x = 0, y = -3 - 0 = -3, so one point is (0, -3).

When x = 1, y = -3 - 1 = -4, so another point is (1, -4).

When x = -1, y = -3 - (-1) = -2, so another point is (-1, -2).

By repeating this process for different values of x, we can find more points that satisfy the equation.

To find the points that satisfy the equation y = x - 3, we can again substitute different values of x and solve for y.

When x = 0, y = 0 - 3 = -3, so one point is (0, -3).

When x = 1, y = 1 - 3 = -2, so another point is (1, -2).

When x = -1, y = -1 - 3 = -4, so another point is (-1, -4).

To find the points that satisfy the equation y = 3x + 2, we can once again substitute different values of x and solve for y.

When x = 0, y = 3(0) + 2 = 2, so one point is (0, 2).

This interval is wider than the confidence interval in part (a) and the prediction interval in part (b) because it is based on the entire population of metal pieces, not just a sample.

(a) To find a 99% confidence interval on the mean diameter, we can use the t-distribution with n-1 degrees of freedom since the population standard deviation is not known. The formula for the confidence interval is:

CI = x ± tα/2,s/√n

where x is the sample mean, s is the sample standard deviation, n is the sample size, and tα/2 is the t-value with (n-1) degrees of freedom for the desired level of confidence α.

Plugging in the values, we get:

CI = 1.0056 ± t0.005/2,0.0246/√9

= 1.0056 ± 0.025

= (0.9806, 1.0306)

Therefore, we can be 99% confident that the true mean diameter of the metal pieces produced by the machine is between 0.9806 and 1.0306 centimeters.

(b) To compute a 99% prediction interval on a measured diameter of a single metal piece taken from the machine, we can use the formula:

PI = x ± tα/2,s(1 + 1/n)√(1 + 1/n)

where x is the point estimate of the diameter (in this case, the sample mean), s is the sample standard deviation, n is the sample size, and tα/2 is the t-value with (n-1) degrees of freedom for the desired level of confidence α.

Plugging in the values, we get:

PI = 1.0056 ± t0.005/2,0.0246(1 + 1/9)√(1 + 1/9)

= 1.0056 ± 0.052

= (0.9536, 1.0576)

Therefore, we can be 99% confident that a single metal piece produced by the machine will have a diameter between 0.9536 and 1.0576 centimeters.

(c) To find the 99% tolerance limits that will contain 95% of the metal pieces produced by this machine, we can use the formula:

TL = x ± kσ

where x is the sample mean, σ is the population standard deviation (which is estimated by the sample standard deviation s), k is the number of standard deviations from the mean that will contain the desired percentage of the population (in this case, 95% or 1.96 standard deviations for a normal distribution).

Plugging in the values, we get:

TL = 1.0056 ± 1.96(0.0246)

= (0.9573, 1.0539)

Therefore, we can be 99% confident that 95% of the metal pieces produced by the machine will have diameters between 0.9573 and 1.0539 centimeters. This interval is wider than the confidence interval in part (a) and the prediction interval in part (b) because it is based on the entire population of metal pieces, not just a sample.

Answer:

Colbie did not complete the square correctly.

Colbie failed to add the square of half the coefficient of the term in x to both sides of the equation. She only added 25 to the left side of the equation. She also factored x² + 10x + 25 incorrectly by using a subtraction sign in the binomial rather than an addition sign.

Step-by-step explanation:

Given quadratic equation:

[tex]2x^2+20x-48=0[/tex]

As the leading coefficient is not one, to complete the square we must first divide both sides of the equation by the leading coefficient, 2:

[tex]\dfrac{2x^2+20x-48}{2}=\dfrac{0}{2}[/tex]

[tex]x^2+10x-24=0[/tex]

Now move the constant to the right side of the equation by adding 24 to both sides of the equation:

[tex]\begin{array}{rcr}x^2+10x-24&=&0\\\vphantom{\dfrac12}+24 & &+24\\\cline{1-3}\vphantom{\dfrac12}x^2+10x\phantom{-24.}&=&24\end{array}[/tex]

We need to make the left side of the equation a perfect square trinomial. To do this, add the square of half the coefficient of the term in x to both sides of the equation.

The coefficient of the term in x is 10. Therefore, the square of half of this is 25:

[tex]\left(\dfrac{10}{2}\right)^2=5^2=25[/tex]

This is the point at which Colbie made her first mistake. She didn't add the square of half the coefficient of the term in x to both sides of the equation - she only added it to the left side.

Add 25 to both sides of the equation:

[tex]x^2+10x+25=24+25[/tex]

[tex]x^2+10x+25=49[/tex]

To continue to solve the equation, factor the perfect square trinomial on the left side of the equation:

[tex](x+5)^2=49[/tex]

↑ Colbie made her second mistake here. She factored x² + 10x + 25 incorrectly by using a subtraction sign in the binomial rather than an addition sign.

Square root both sides:

[tex]\sqrt{(x+5)^2}=\sqrt{49}[/tex]

[tex]x+5=\pm7[/tex]

Subtract 5 from both sides:

[tex]x+5-5=-5\pm7[/tex]

[tex]x=-5\pm7[/tex]

Therefore, the solutions are:

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 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

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