A wildlife group is trying to determine how many wild hogs are in a certain area. They trapped, tagged, and released 20 wild hogs. Later, they counted 8 wild hogs out of the 40 they saw.

What can the wildlife group estimate is the total population of wild hogs in that area?

A. 80
B. 90
C. 100
D. 16

Answers

Answer choice C is correct. That is the total population of wild hogs in that particular area is 100.

What do you mean by total population in a area?

Total population in an area refers to the number of individuals of a particular species or group living in a specific geographical region or habitat. This can include both visible and hidden individuals, such as animals that are difficult to spot or track. Total population is an important measure for conservation and management efforts, as it helps determine the size of a population and whether it is growing or declining.

Given that 20 wild hogs were tagged and later they saw 8 tagged wild hogs out of 40 recaptured wild hogs. We need to find the total population of wild hogs in that area.

From the given information we can see,

(Number of hogs tagged) / (Total population) = (Number of tagged hogs recaptured) / (Number of hogs recaptured)

⇒ 20 / x = 8 / 40

⇒ 8x = 20 × 40

⇒ 8x = 800

⇒ x = 100

Therefore, the wildlife group can estimate that the total population of wild hogs in the area is 100.

The average daily balance of a credit card for the month of March was $1900 and the unpaid balance at the end of the month was $1700. If the annual percentage rate is 32.4% of the average daily balance, what is the total balance on the next billing date, April 1?

Round your answer to the nearest cent.

Answers

Using the average daily balance, the total balance on the next billing date, April 1 is $5,059.73.

What is the average daily balance?

The average daily balance is a credit card method of computing finance charges.

To determine the average daily balance, the sum of the daily balances over your billing cycle is divided by the number of days in the billing cycle.

The finance charge is then the product of the average daily balance multiplied by the APR and the number of days involved, divided by 365 days.

Average daily balance = $1,900

Unpaid balance at month-end = $1,700

APR = 32.4%

The finance charge for the month = $9.73 ($1900 x 32.4% x 30/365)

The total balance on the next billing date, April 1 = $5,059.73 ($5,050 + $9.73)

Thus, on April 1, the next billing cycle, the balance on the card is $5,059.73.

An island is located 48 miles N23°38'W of a city. A
freighter in distress radios its position as N11°26'E of the
island and N12° 16'W of the city. How far is the freighter
from the city?

Answers

The freighter is approximately 164.33 miles from the city.

How to determine how far is the freighter from the city?

We can use the Law of Cosines to solve this problem. Let's label the distances as follows:

d: distance between the city and the freighter

x: distance between the city and the island

y: distance between the island and the freighter

First, we need to find x using the given coordinates:

N23°38'W is equivalent to S23°38'E, so we have:

cos(23°38') = x/48

x = 48cos(23°38') ≈ 42.67 miles

Next, we can use the coordinates of the freighter to find y:

N11°26'E is equivalent to E11°26'N, and N12°16'W is equivalent to S12°16'E. This means that the angle between the island and the freighter is:

23°38' + 11°26' + 12°16' = 47°20'

cos(47°20') = y/d

We can rearrange this equation to solve for y:

y = dcos(47°20')

Now we can use the Law of Cosines to solve for d:

d² = x² + y² - 2xy cos(90° - 47°20')

d² = 42.67² + (d cos(47°20'))² - 2(42.67)(d cos(47°20')) sin(47°20')

d² = 1822.44 + d² cos²(47°20') - 2(42.67)(d cos(47°20')) sin(47°20')

d² - d² cos²(47°20') = 1822.44 - 2(42.67)(d cos(47°20')) sin(47°20')

d² (1 - cos²(47°20')) = 1822.44 - 2(42.67)(d cos(47°20')) sin(47°20')

d² sin²(47°20') = 1822.44 - 2(42.67)(d cos(47°20')) sin(47°20')

d² = (1822.44 - 2(42.67)(d cos(47°20')) sin(47°20')) / sin²(47°20')

d ≈ 164.33 miles

Therefore, the freighter is approximately 164.33 miles from the city.

Form a polynomial f(x) with real coefficients having the given degree and zeros.
Degree 4; zeros: 6 (Multiplicity 2); 3i
Enter the expanded polynomial. Let a represent the leading coefficient.
f(x) = a( )

Answers

Answer:

Step-by-step explanation:

The polynomial f(x) with real coefficients, degree 4, and zeros 6 (multiplicity 2), 3i can be formed as follows:

Since the zero 6 has a multiplicity of 2, it appears twice in the factored form of f(x), i.e., (x-6)(x-6) = (x-6)^2.

The other zero is 3i, which means its complex conjugate, -3i, is also a zero. Therefore, the factored form of f(x) can be written as:

(x-6)^2(x-3i)(x+3i)

Expanding this expression, we get:

f(x) = (x-6)^2(x^2 + 9)

Multiplying this out, we get:

f(x) = x^4 - 12x^3 + 81x^2 - 216x + 324

Therefore, the polynomial f(x) with real coefficients, degree 4, and zeros 6 (multiplicity 2), 3i can be written as:

f(x) = x^4 - 12x^3 + 81x^2 - 216x + 324.

The polynomial f(x) with real coefficients having the given degree and zeros is:

f(x) = a(x - 6)^2(x - 3i)(x + 3i)

To expand this polynomial, we can use the fact that (a + b)(a - b) = a^2 - b^2. Substituting a = x - 6 and b = 3i, we get:

(x - 6 + 3i)(x - 6 - 3i) = (x - 6)^2 + 9

Therefore, the expanded polynomial is:

f(x) = a(x - 6)^2(x - 3i)(x + 3i)
f(x) = a(x - 6)^2(x^2 + 9)
f(x) = a(x^4 - 12x^3 + 57x^2 - 108x + 81)

So, the expanded polynomial is f(x) = a(x^4 - 12x^3 + 57x^2 - 108x + 81).

Paul bakes raisin bars in a pan shaped like a rectangular prism. The volume of the pan is 252 cubic inches. The length of the pan is 12 inches, and its width is 10-1/2 inches. What is the height of the pan? Enter your answer in the box​

Answers

Answer:

The volume of a rectangular prism is given by the formula V = lwh, where l, w, and h are the length, width, and height of the prism, respectively. We are given that the volume of the pan is 252 cubic inches, the length is 12 inches, and the width is 10-1/2 inches.

So, 252 = 12 x 10.5 x h

Simplifying the right side of the equation, we get:

252 = 126h

Dividing both sides by 126, we get:

h = 2

Therefore, the height of the pan is 2 inches.



The height of the pan can be found by dividing the volume of the pan by the area of the pan's base.

Step 1: Find the area of the base.

The area of the base is the length multiplied by the width:

Area = Length * Width = 12 inches * 10.5 inches = 126 inches²

Step 2: Divide the volume of the pan by the area of the base:

Height = Volume / Area = 252 cubic inches / 126 inches² = 2 inches

A normal distribution has a mean of 33 and a standard deviation of 4. Find the probability that a randomly selected x-value from the distribution is in the given interval. a. between 29 and 37 b. between 33 and 45 c. at least 29 d. at most 21

Answers

Step-by-step explanation:

We can use the standard normal distribution to calculate probabilities for a normal distribution with mean 33 and standard deviation 4. We just need to standardize the intervals using the formula:

z = (x - mu) / sigma

where x is the specific value in the interval, mu is the mean, sigma is the standard deviation, and z is the corresponding z-score.

a. Between 29 and 37:

z1 = (29 - 33) / 4 = -1

z2 = (37 - 33) / 4 = 1

Using a standard normal distribution table, the cumulative probability of z being between -1 and 1 is approximately 0.6827.

So the probability that a randomly selected x-value from the distribution is between 29 and 37 is approximately 0.6827.

b. Between 33 and 45:

z1 = (33 - 33) / 4 = 0

z2 = (45 - 33) / 4 = 3

The cumulative probability of z being between 0 and 3 is approximately 0.4987.

So the probability that a randomly selected x-value from the distribution is between 33 and 45 is approximately 0.4987.

c. At least 29:

z = (29 - 33) / 4 = -1

The cumulative probability of z being less than -1 is approximately 0.1587. So the probability that a randomly selected x-value from the distribution is at least 29 is approximately 1 - 0.1587 = 0.8413.

d. At most 21:

z = (21 - 33) / 4 = -3

The cumulative probability of z being less than -3 is very close to 0. So the probability that a randomly selected x-value from the distribution is at most 21 is approximately 0.

Find the volume of the two prisms.
someone pls help me I need to ace this test

Answers

Therefore, the total volume of the two prisms is 10,404 cubic inches.

What is volume?

Volume is a measure of the amount of space occupied by a three-dimensional object. It is typically measured in cubic units, such as cubic meters (m³), cubic feet (ft³), or cubic centimeters (cm³). The volume of an object is calculated by multiplying its length, width, and height or by using an appropriate formula for the shape of the object.

Here,

The two prisms have the same dimensions of 17 inches in height, 18 inches in base, and 17 inches in length and width.

To find the volume of a prism, we multiply the area of the base by the height. The base of the prism is a rectangle with length 18 inches and width 17 inches, so the area of the base is:

Area of base = length × width

= 18 in × 17 in

= 306 in²

Therefore, the volume of one prism is:

Volume = area of base × height

= 306 in² × 17 in

= 5202 in³

The volume of the two prisms combined is simply twice the volume of one prism:

Total volume = 2 × 5202 in³

= 10404 in³

Plotting the constraints 3x + 6y ≤ 900, x + y ≤ 200 and y ≤ 125 on the same graph, the coordinates of the feasible region are:

(x, y) = (100, 100), (75, 125) and (50, 125)

So, we have

Z = 8(100) + 16(100) = 2400

Z = 8(75) + 16(125) = 2600

Z = 8(50) + 16(125) = 2400

How many bucket loads would it take to bucket out the world’s ocean

Answers

Answer:

Impossible to know, or best guess

Step-by-step explanation:

It is impossible to determine exactly how many bucket loads it would take to empty the world's ocean because the volume of the ocean is constantly changing due to factors such as tides, currents, and sea level rise. However, we can estimate the approximate volume of the ocean and calculate the number of bucket loads needed based on that estimate.

The approximate volume of the world's ocean is 1.332 billion cubic kilometers (km³) or 332.5 million cubic miles (mi³). Assuming that each bucket can hold 10 liters or 0.01 cubic meters (m³) of water, we can calculate the number of bucket loads needed to empty the ocean as follows:

1 km³ = 1,000,000,000 m³

1,332,000,000 km³ = 1.332 x 10¹⁸ m³

1.332 x 10¹⁸ m³ / 0.01 m³ per bucket = 1.332 x 10²⁰ bucket loads

Therefore, it would take approximately 1.332 x 10²⁰ or 133,200,000,000,000,000,000 bucket loads to empty the world's ocean. This number is so large that it is practically impossible to even visualize, let alone accomplish.

To find the length of a row of bookshelves, we can use the square root function, as the length of a row of bookshelves will be proportional to the square root of the area of the space that Isabel rents.

Mathematically, we can express f(x) as: f(x) = √(x)

Where x represents the area of the space that Isabel rents, and f(x) represents the total length of a row of bookshelves.

What is the square root function?

The above function takes the square root of the area x, which gives us the length of a row of bookshelves in feet, assuming that the area is in square feet. As x increases, f(x) will also increase, indicating that the length of the row of bookshelves will also increase as Isabel rents a larger area in the warehouse.

To find the length of a row of bookshelves, we can use the square root function, denoted as √(x), where x represents the area of the space that Isabel rents.

Determine the area of the space that Isabel rents, denoted as x. This could be obtained from the rental agreement or by measuring the area of the space using appropriate units (e.g., square feet).Take the square root of x using a calculator or by using a mathematical formula. The square root of x, denoted as √(x), represents the positive value which, when multiplied by itself, gives x.The resulting value of √(x) represents the total length of a row of bookshelves in feet (assuming that the area is in square feet), as per the requirement given in the problem statement.

For example, if Isabel rents an area of 324 square feet, we can find the length of a row of bookshelves as follows:

x = 324

f(x) = √(x) = √(324) = 18

So, the length of a row of bookshelves would be 18 feet in this case.

Answers

15.048 deciliters is equivalent to 1 quart.

What is conversion?

Conversion is the process of changing a quantity from one unit of measure to another unit of measure using a conversion factor or a formula.

We have:

To convert meters to feet, multiply by 3.28.

To convert liters to gallons, multiply by 0.26.

To convert kilograms to pounds, multiply by 2.20.

To convert deciliters to quarts, divide by 15.048.

Let's use these conversions to convert the given measurement:

15.048 dL = qt

Dividing both sides by 15.048, we get:

1 dL = qt/15.048

Multiplying both sides by 0.946353, which is the number of quarts in a liter, we get:

0.946353 dL = qt/15.048 * 0.946353

Simplifying the right-hand side, we get:

0.946353 dL = qt/15.961

Multiplying both sides by 3.78541, which is the number of liters in a gallon, we get:

3.78541 * 0.946353 dL = 3.78541 * qt/15.961

Simplifying the left-hand side, we get:

Factor out 4 from the denominator

So, we have

f(x) = (x - 1)/(4(x - 4))

This means that

f(x) = (x - 1)/(4(x - 4)) is equivalent to f(x) = (x - 1)/(4x - 16)

So, we can plot the graph of f(x) = (x - 1)/(4(x - 4)) to represent f(x) = (x - 1)/(4x - 16)

What is the length of the unknown leg
of the right triangle?
2 ft
3 ft
(The figure is not drawn to scale.)
The length of the unknown leg of the right triangle is ft.
(Round to one decimal place as needed.)

Answers

Thus, the unknown leg x of the right angled triangle is found as 2.2 ft.

Explain about the right triangle:

A right triangle is one that has an interior angle of 90 degrees. The hypotenuse, which is also the side of the right triangle that faces the right angle, is its longest side. The height and base make up the two arms of the right angle.

What a Right Triangle Looks Like

In a right triangle, the right angle is often the biggest angle.The longest side is the hypotenuse, which is the side that faces the right angle.A right triangle cannot include any obtuse angles.

For the given right triangle:

Let the unknown length be 'x'.

Using the Pythagorean theorem:

3² = 2² + x²

x² = 3² - 2²

x² = 9 - 4

x² = 5

x = 2.2

Thus, the unknown leg x of the right angled triangle is found as 2.2 ft.

A group of students was to clean up to two areas in their school. area a was 1 1 2 times of area b. in the morning (half of a day), the number of students cleaning area a was 3 times that of the number of students in area b. in the afternoon (another half of a day), 7/12 of the students worked in area a while the rest of them in area b. at the end of the day, area a was done, but area b still needed 4 students to work one more day before it was done. how many were there in this group of students?

Answers

There were 24 students working in area B in the morning, and 3 times as many, or 72 students, working in area A. The total number of students is then 24 + 72 = 96.

What is an area?

In geometry, an area is the measurement of the amount of space inside a two-dimensional flat surface such as a square, rectangle, triangle, circle, or any other shape. It is usually expressed in square units, such as square centimeters (cm²) or square meters (m²), and is calculated by multiplying the length and width of a rectangular shape or by using specific formulas for different geometric shapes such as the base times the height divided by 2 for a triangle or pi times the radius squared for a circle. The concept of area is fundamental in many branches of mathematics, physics, engineering, and other fields where the measurement of the extent of a surface is important.

According to the given equation

Let's assume that the number of students working in area b is x. Then the number of students working in area A is 3x (since there are three times as many students working in area A as in area b in the morning).

Let A be the area of area a, and B be the area of area b. We know that A = 1.5B (since area a is 1 1 2 times the area of area b).

In the morning, the total number of students is x + 3x = 4x.

In the afternoon, 7/12 of the students work in area a, and the rest work in area b. So, the number of students working in area A in the afternoon is 7/12 * 4x = 7x/3, and the number of students working in area b is (1 - 7/12) * 4x = 5x/12.

Since area a was finished at the end of the day, we know that the total area cleaned by the students is A + B = 1.5B + B = 2.5 B. This means that the number of students working in area b is enough to finish 0.5B (since area a was already finished), but 4 more students are needed to finish the remaining 0.5B.

So, we can set up the following equation:

(5x/12) / x = 0.5 / (0.5 + 4/x)

Simplifying this equation, we get:

5x = 6x + 24

x = 24

Therefore, there were 24 students working in area b in the morning, and 3 times as many, or 72 students, working in area A. The total number of students is then 24 + 72 = 96.
