To find the sample size necessary for an 85% confidence level with a maximal error of estimate E=0.09 for the mean weights of the hummingbirds, we have to use the following formula:

n = [(z_(α/2)*σ)/E]²

Here, we know that the population standard deviation (σ) is 0.29 grams,

the maximal error of estimate (E) is 0.09 grams, and the confidence level (C) is 85%.

We have to find the value of n. For this,

we need to find the critical value of z \((z_{(α/2))\) from the z-tables, which corresponds to the given confidence level (85%).

Using the z-table, we get:

\(z_{(α/2)\) = 1.44

Substitute the given values into the formula:

n = [(\(z_{(α/2)\)*σ)/E]²n = [(1.44*0.29)/0.09]²n = [0.4176/0.09]²n = 4.64²n = 21.5

Rounding up the value of n, we get the sample size necessary for an 85% confidence level with a maximal error of estimate E=0.09 for the mean weights of the hummingbirds is n = 22. Therefore, the answer is 22.

To find the sample size necessary for an 85% confidence level with a maximal error of estimate of E=0.09, you can use the formula: n = (Z * σ) / E, where n is the sample size, Z is the z-score corresponding to the desired confidence level, σ is the population standard deviation, and E is the maximal error of estimate.

To find the sample size necessary for an 85% confidence level with a maximal error of estimate of E=0.09, we can use the formula:

n = (Z * σ) / E

where n is the sample size, Z is the z-score corresponding to the desired confidence level, σ is the population standard deviation, and E is the maximal error of estimate.

In this case, the Z-score for an 85% confidence level is approximately 1.44. Substituting the given values into the formula, we get:

n = (1.44 * 0.29) / 0.09 ≈ 4.65

Rounding up to the nearest whole number, the sample size necessary is 5.

(a) The equation z = z^2 represents a paraboloid.

To sketch the graph of this equation, we can plot some points and observe the shape of the paraboloid. However, it's important to note that the equation z = z^2 is not a well-defined equation as it leads to multiple interpretations and can cause mathematical inconsistencies. The equation implies that z is equal to either 0 or 1, but it does not specify a specific relationship between x, y, and z.

(b) The equation y² + 2² = 1 + x² represents a cylinder.

To sketch the graph of this equation, we can treat it as a three-dimensional equation and interpret it as a cylinder. The equation implies that the sum of the squares of y and 2 is equal to 1 plus the square of x. This equation describes a right circular cylinder with its axis parallel to the z-axis and centered at the origin.

In order to identify these mentioned terms, it is important that each of them is defined.

Diameter: It is a line that passes through the center of the circle from one endpoint to another. It is two times the radius of the circle

Radius: It is a line drawn from the center of the circle to one endpoint of the circle.

It is half of the diameter.

Chord: It is a line drawn from one endpoint of the circle to another but does not necessarily pass through the center. Diameter is an example of a chord, but a chord does not have to be a diameter

Arc: It is a segment of the circumference of a circle

Circumference: is the total distance around the circle

From the diagram above:

|AB| is a diameter

|OA| or |OB| is the radius

|CD| is the chord

Arc CD is indicated on the diagram

If a circle has a radius of 2 cm:

Diameter = 2 x radius

Diameter = 2 x 2

Diameter = 4 cm

Therefore, if a circle has a radius of 2 cm, the diameter is 4 cm

After 3 hours, the boat is approximately 16.43 miles from the marina, and the bearing from the boat back to the marina is approximately 209.9°

We have,

To solve this problem, we can break down the boat's motion into two components: north-south displacement and east-west displacement.

Given:

The boat travels due south for 1 hour at a constant speed of 15 mph.

The boat then changes course to a bearing of S47°E and travels for 2 hours at the same constant speed of 15 mph.

a.

To find how far the boat is from the marina after 3 hours, we need to calculate the total displacement using the Pythagorean theorem.

First, let's find the north-south displacement:

Distance = Speed x Time = 15 mph x 1 hour = 15 miles

Next, let's find the east-west displacement using the given bearing:

Angle of S47°E = 180° - 47° = 133°

Using trigonometry, we can find the east-west displacement:

East-West Displacement = Distance x cos(Angle) = 15 miles x cos(133°)

Now, let's calculate the total displacement:

Total Displacement = √(North-South Displacement² + East-West Displacement²)

b.

To find the bearing from the boat back to the marina, we can use trigonometry to calculate the angle between the displacement vector and the north direction.

Let's calculate the values:

a. North-South Displacement = 15 miles

b. East-West Displacement = 15 miles x cos(133°)

c. Total Displacement = sqrt(North-South Displacement² + East-West Displacement²)

b. Bearing = atan(East-West Displacement / North-South Displacement) + 180°

Now, let's perform the calculations:

a. North-South Displacement = 15 miles

b. East-West Displacement = 15 miles x cos(133°) ≈ -6.83 miles (rounded to two decimal places)

c. Total Displacement = √(15² + (-6.83)²) ≈ 16.43 miles (rounded to two decimal places)

b.

Bearing = atan(-6.83 / 15) + 180° ≈ 209.9° (rounded to one decimal place)

Therefore,

After 3 hours, the boat is approximately 16.43 miles from the marina, and the bearing from the boat back to the marina is approximately 209.9°

The variable X has a binomial distribution in the following distributions:

A. When the medicine is tried with two patients, X is the number of patients for whom the medicine worked.

C. When the medicine is tried with six patients, X is the number of patients for whom the medicine worked.

In a binomial probability distribution, the number of "Successes" in a series of n experiments is represented as either success/yes/true/one (probability p) or failure/no/false/zero (probability q = 1 p), depending on the outcome's boolean value.

In a binomial distribution, we have a fixed number of independent trials (in this case, the number of patients), and each trial has only two possible outcomes (success or failure). The probability of success remains the same for each trial (in this case, the probability of the medicine working is 30%).

Option B does not represent a binomial distribution since it counts the number of patients for whom the medicine does not work, which is the complement of success. Option D is not a binomial distribution as it counts the number of doses each patient needs to take, which is not a success/failure outcome.

So, the correct answers are:

A. When the medicine is tried with two patients, X is the number of patients for whom the medicine worked.

C. When the medicine is tried with six patients, X is the number of patients for whom the medicine worked.

Account 1 has the highest effective annual interest rate (0.042666142)

Step-by-step explanation:

Hi, to answer this question we have to apply the Effective Annual Interest Rate formula:  

EAIR = [(1+r/n)^n ]-1

Where:

r = nominal interest rate

n = number of periods

If interest is compounded annually, then n = 1; if semi-annually, then n = 2; quarterly, then n = 4; monthly, then n = 12

SO:

Account 1: Interest is compounded quarterly at an annual rate of 4.20%.  

EAIR = [(1+r/n)^n ]-1 = [(1+(4.20/100)/4)^4 ]-1 = 0.042666142

Account 2: Interest is compounded monthly at an annual rate of 4.15%.  

EAIR = [(1+r/n)^n ]-1 = [(1+(4.15/100)/12)^12 ]-1 =0.042298535

Account 3: Interest is compounded semiannually at an annual rate of 4.10%

EAIR = [(1+r/n)^n ]-1 = [(1+(4.10/100)/2)^2]-1 = 0.04142025

Account 4: Interest is compounded annually at a rate of 4.25%.

EAIR = [(1+r/n)^n ]-1 = [(1+(4.25/100)/1)^1 ]-1 = 0.0425

Since:

0.042666142 (1) < 0.0425 (4) < 0.042298535(2) <0.041420258(3)

Following an exponential distribution with a mean of 15 seconds, the 60th percentile for the amount of time between customers entering Clay's store is approximately 13.74 seconds.

Based on the information provided, Clay's grocery store experiences customer arrivals following an exponential distribution with a mean of 15 seconds. To find the 60th percentile for the amount of time between customers entering the store, we can use the following formula:

Percentile = Mean * ln(1 / (1 - Percentile in Decimal Form))

In this case, the 60th percentile in decimal form is 0.6. Plugging the values into the formula, we get:

60th Percentile = 15 * ln(1 / (1 - 0.6))

60th Percentile ≈ 15 * ln(1 / 0.4)

60th Percentile ≈ 15 * ln(2.5)

60th Percentile ≈ 15 * 0.9163
