We can see that 7/4 is located between 3/4 and 1 on the first interval, and 9/4 is located between 2 and 5/2 on the second interval.

To partition each whole number interval into fourths, divide each interval by 4. Label 7/4 between 3/4 and 1 and label 9/4 between 2 and 5/2 on an extended scale from 0 to 3.

To partition each whole number interval into fourths, we can divide each interval by 4. For example, the interval from 0 to 1 can be divided into fourths as follows:

0 -------- 1/4 -------- 1/2 -------- 3/4 -------- 1

Now, to label 7/4 and 9/4 on this scale, we can extend it by adding another interval from 1 to 2 and dividing it into fourths as well. This would give us the following scale:

0 -------- 1/4 -------- 1/2 -------- 3/4 -------- 1 -------- 5/4 -------- 3/2 -------- 7/4 -------- 2 -------- 9/4 -------- 5/2 -------- 11/4 -------- 3

The 90% confidence interval for the population proportion of females is (0.261, 0.375). Answer: d. 16 to 31.

To compute a 90% confidence interval for the population proportion of females using the Golfer Data, you can use the following formula:

CI = p ± z*√(P(1-P)/n)

where P is the sample proportion, z is the z-score associated with the desired confidence level (in this case, 1.645 for 90% confidence), and n is the sample size.

From the Golfer Data, we can see that there are 84 females out of a total of 264 golfers:

n = 264

P = 84/264 = 0.318

Plugging these values into the formula, we get:

CI = 0.318 ± 1.645*√(0.318(1-0.318)/264)

CI = 0.318 ± 0.057

CI = (0.261, 0.375)

To develop a 95% confidence interval for the proportion of all consumers who prefer to purchase domestic automobiles, we can use the formula:

CI = p ± z*(√(p*(1-p)/n))

where:

p = proportion of consumers who prefer domestic automobiles = 240/600 = 0.4
n = sample size = 600
z = z-score for 95% confidence level = 1.96

Answer:

∠ PQR = 18°

Step-by-step explanation:

the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

∠ PQR is an exterior angle of the triangle , then

∠ PQR = ∠OPQ + ∠ QOP , that is

4x - 10 = x + 9 + x - 5

4x - 10 = 2x + 4 ( subtract 2x from both sides )

2x - 10 = 4 ( add 10 to both sides )

2x = 14 ( divide both sides by 2 )

x = 7

Then

∠ PQR = 4x - 10 = 4(7) - 10 = 28 - 10 = 18°

The angular velocity of the circle is approximately 19 m/s.

In order to find the missing quantity, we can use the relationship between linear velocity and angular velocity in a circle. The linear velocity of a point on the edge of a circle is the product of the radius and the angular velocity. This can be expressed as:

v = r * w

where v is the linear velocity, r is the radius, and w is the angular velocity.

To find the value of w, we can rearrange this equation to solve for w:

w = v / r

Substituting the given values of v and r, we get:

w = 1235 m/min / 65 m

w = 19 m/s

It's important to note that units must be consistent when using formulas to solve problems. In this case, we converted the given linear velocity from m/min to m/s before plugging it into the formula.

1. The instantaneous rate of change in the amount after 2 years is [tex]$1,605.64[/tex] per year

2. The instantaneous rate of change in the amount at the time the amount is equal to [tex]$14,101[/tex] is approximately $994.78 per year

[tex]A = P[/tex]× [tex]e^{rt}[/tex]

where P is the principal (initial investment), r is the annual interest rate as a decimal, and t is the time in years.

For this problem, we have P = $10,000, r = 0.067 (6.7% as a decimal), and we want to find the instantaneous rate of change in the amount after 2 years, so t = 2.

Part 1:

To find the instantaneous rate of change, we need to take the derivative of the function A(t) with respect to t:

[tex]dA/dt = Pre^{rt}[/tex]

At[tex]t = 2[/tex], we have:

[tex]A(2) = $10,000e^{0.0672}[/tex]

[tex]= $11,868.94[/tex]

[tex]dA/dt = $10,0000.067e^{0.067}[/tex]×[tex]2)[/tex]

[tex]= $1,605.64[/tex]

So the instantaneous rate of change in the amount after 2 years is $1,605.64 per year

Part 2:

To find the time at which the amount in the account is $14,101, we need to solve the equation A = $14,101 for t:

[tex]$14,101[/tex][tex]= $10,000[/tex] × [tex]e^{0.067t}[/tex]

Dividing both sides by $10,000:

[tex]1.4101 = e^{0.067t}[/tex]

Taking the natural logarithm of both sides:

[tex]ln(1.4101) = 0.067t[/tex]

Solving for t:

[tex]t = ln(1.4101)/0.067[/tex]

≈ [tex]3.5 years[/tex]

So the time at which the amount in the account is $14,101 is approximately 3.5 years.

To find the instantaneous rate of change at this time, we need to evaluate the derivative at t = 3.5:

[tex]dA/dt = $10,0000.067e^{0.067}[/tex]×[tex]3.5)[/tex]

≈ [tex]$994.78[/tex]

So the instantaneous rate of change in the amount at the time the amount is equal to $14,101 is approximately $994.78 per year

The probability that the subject actually has an IQ below 150 given that they are labeled as having an IQ over 150 is approximately 0.00073276, or 0.07328% when rounded to five decimal places.

Let's use Bayes' theorem to solve the problem. Let A be the event that the subject has an IQ over 150, and B be the event that the subject actually has an IQ below 150. We want to find P(B|A), the probability that the subject has an IQ below 150 given that they are labeled as having an IQ over 150.

From the problem, we know that P(A) = 1/1100, the probability that a random person has an IQ over 150. We also know that P(A|B') = 0.0008, the probability that someone with an IQ below 150 is labeled as having an IQ over 150 due to lucky guessing.

To find P(B|A), we need to find P(A|B), the probability that someone with an IQ below 150 is labeled as having an IQ over 150. We can use Bayes' theorem to find this probability:

P(A|B) = P(B|A) * P(A) / P(B)

We know that P(B) = 1 - P(B'), the probability that someone with an IQ below 150 is not labeled as having an IQ over 150. Since everyone with an IQ over 150 is labeled as such, we have:

P(B) = 1 - P(A')

where P(A') is the probability that a random person has an IQ below 150 or, equivalently, 1 - P(A).

Plugging in the given values, we have:

P(A|B) = P(B|A) * P(A) / (1 - P(A))

P(A|B) = P(B|A) * 1/1100 / (1 - 1/1100)

P(A|B) = 0.0008 * 1/1100 / (1 - 1/1100)

P(A|B) ≈ 0.00073276

Therefore, the probability that the subject actually has an IQ below 150 given that they are labeled as having an IQ over 150 is approximately 0.00073276, or 0.07328% when rounded to five decimal places.

Since d satisfies all three properties of an equivalence relation, we conclude that d is indeed an equivalence relation on Z.

To prove that d is an equivalence relation on Z, we need to show that it satisfies three properties: reflexivity, symmetry, and transitivity.

Reflexivity: For any m ∈ Z, we have [tex]m^2 - m^2[/tex] = 0, which is divisible by 3. Therefore, m is related to itself under d, so d is reflexive.

Symmetry: If m d n, then [tex]3 | (m^2 - n^2)[/tex]). This means that there exists an integer k such that [tex]m^2 - n^2 = 3k.[/tex]

Rearranging this equation, we get n^2 - m^2 = -3k, which implies that 3 divides (n^2 - m^2) as well. Therefore, n d m, and d is symmetric.

Transitivity: Suppose m d n and n d p. Then, we have [tex]3 | (m^2 - n^2)[/tex] and [tex]3 | (n^2 - p^2)[/tex].

Adding these two equations, we get   [tex]3 | ((m^2 - n^2) + (n^2 - p^2)),[/tex], which simplifies to [tex]3 | (m^2 - p^2).[/tex] Therefore, m d p, and d is transitive.

The lateral surface area of a cone is 15π units².

Option  A is the correct answer.

We have,

The lateral area of a three-dimensional object is the total surface area of the object excluding the area of the bases.

So,

The given figure is a cone.

Now,

The lateral surface area of a cone = πrl

where r is the radius of the base of the cone, and l is the slant height of the cone.

The slant height is the distance from the apex of the cone to any point on the edge of the base.

Now,

Applying the Pythagorean,

l² = 4² + 3²

l² = 16 + 9

l² = 25

l = 5

So,

Substituting the values.
