The estimated total number of fur seal pups in Rookery A is 8905 (rounded to the nearest whole number).

Proportion refers to the relationship between the part and the whole. It is a measure that expresses the size of one subset (part) relative to the size of the entire population (whole). A proportion is usually expressed as a fraction or a percentage.

A whole number is a number that does not have any fractional or decimal part. It is a positive integer (1, 2, 3, ...) or zero (0). Whole numbers are used to count objects or things that cannot be divided into parts.

To estimate the total number of fur seal pups in Rookery A, we can use the proportion of tagged pups in the sample to the total tagged pups in the rookery.

The proportion of tagged pups in the sample is 244/500 = 0.488.

Assuming that the proportion of tagged pups in the sample is representative of the proportion of tagged pups in the entire rookery, we can set up a proportion:

0.488 = (number of tagged pups in Rookery A) / (total number of pups in Rookery A)

Solving for the total number of pups in Rookery A, we get:

(total number of pups in Rookery A) = (number of tagged pups in Rookery A) / 0.488

(total number of pups in Rookery A) = 4350 / 0.488

(total number of pups in Rookery A) ≈ 8905

Therefore, the estimated total number of fur seal pups in Rookery A is 8905 (rounded to the nearest whole number).

The predicted width of a foot with a length of 22 centimeters is 9.16 centimeters.

The soft drink vendor's maximum profit per day is $5250, and he must sell 1500 cans of soda pop to reach the maximum profit.

To find the maximum profit per day for the soft drink vendor, we need to use the formula P(x) = 0.001x^2 + 3x + 1800, where x is the number of cans of soda pop sold in one day.

To find the maximum profit, we need to find the vertex of the parabola represented by the profit function. The x-coordinate of the vertex is given by -b/2a, where a = 0.001 and b = 3. Plugging in these values, we get x = -3/(2*0.001) = -1500.

Since the soft drink vendor cannot sell a negative number of cans, we know that the maximum profit occurs at the closest whole number to x = -1500, which is x = 1500.

To find the maximum profit per day, we can plug in x = 1500 into the profit function:

P(1500) = 0.001(1500)^2 + 3(1500) + 1800 = $5250

Therefore, the soft drink vendor's maximum profit per day is $5250, and he must sell 1500 cans of soda pop to reach the maximum profit.

To find the maximum profit per day and the number of cans needed to reach that profit, we'll first need to find the critical point of the given quadratic profit function, P(x) = -0.001x^2 + 3x - 1800.

Step 1: Find the derivative of P(x) with respect to x. This will give us the rate of change of profit as the number of cans sold changes.

P'(x) = -0.002x + 3

Step 2: Set the derivative equal to zero and solve for x. This will give us the critical point where the maximum profit occurs.

-0.002x + 3 = 0

x = 1500 cans

Step 3: Substitute the critical point (x = 1500) back into the profit function P(x) to find the maximum profit.

P(1500) = -0.001(1500)^2 + 3(1500) - 1800

P(1500) = $600

So, the maximum profit per day is $600, and the soft drink vendor must sell 1500 cans to reach the maximum profit.

The profit function for the soft drink vendor is given by:

P(x) = [tex]0.001x^2 + 3x + 1800[/tex]

To find the maximum profit, we need to find the vertex of the parabola represented by this function. The x-coordinate of the vertex can be found using the formula:

x = -b / (2a)

where a = 0.001 and b = 3. Substituting these values, we get:

x = -3 / (2 * 0.001) = -1500

Since the value of x cannot be negative in this context, we know that the maximum profit occurs at x = 1500. To find the maximum profit, we substitute this value of x into the profit function:

P(1500) =[tex]0.001(1500)^2 + 3(1500) + 1800 = $4800[/tex]

Cash received for interest during  2014 was $3,500 .The following equation can be used to determine the amount of money received as interest in 2014:

Amount received as interest equals Interest Income for 2014 plus the decline in Interest Receivable

The difference between the balance of interest receivable at December 31, 2013, and at December 31, 2014, can be used to calculate the decline in interest receivable:

Reduced interest due = Interest due at December 31, 2013, minus Interest due at December 31, 2014, which equals $1,100 minus $1,400, or -$300.

The fact that the balance of interest receivable increased from 2013 to 2014 indicates that the company produced more interest money during the year than it received. In light of this, the money earned on interest in 2014 is:

Interest income from 2014 plus a decrease in interest receivable equals $3,200 minus (-$300) to $3,500 in interest payments received.

What is Trigonometric ratio?

Trigonometric ratios are defined as the values of all trigonometric functions based on the value of the ratio of the sides of a right triangle. The ratio of the sides of a right triangle to its acute angles are called the trigonometric ratios of that particular angle.

For example,tan(θ) = opposite/adjacent where θ is the angle between the hypotenuse and the base.

We want to solve for x, the length of the adjacent side. We also know that the hypotenuse is 500 ft and the height is y.

Here by the given figure, it is clear that angle between height and hypotenuse is (90°-29°) = 61°

So, θ = 61°

[tex]tan( {61}^{o} ) = \frac{y}{x} [/tex]

Simplifying this expression,

[tex]x = \frac{y}{tan(61°)}[/tex]

To solve for y, for the right angle triangle

[tex]y^2 + x^2 = 500^2[/tex]

Substituting the expression for x from the first equation,

y² + (y/tan(61°))² = 500²

Solving for y, we get:

y = 500 / √(1 + (1/tan(61°))²)

y ≈ 357.98 ft

Finally, we can substitute this value of y into the expression for x that we derived earlier,

x = y/tan(61°)

x ≈ 201.52 ft

Therefore, the value of x is approximately 201.52 ft.

For the given problem, The correct answer will be option 2: The IQR of 13 is the most accurate to use, since the data is skewed.

The Interquartile Range (IQR) is a measure of variability that compares the 25th percentile (Q1) to the 75th percentile (Q3) of a dataset (Q3). It is frequently used to describe the distribution or variability of data that may contain outliers or is not regularly distributed.

The data in the histogram is not evenly distributed in this example because there are many donations at the higher end of the scale (16 to 20), resulting in a positively skewed distribution. Using a range of 20, which indicates the difference between the greatest and lowest value in the dataset, may not adequately depict the data's variability since it is significantly impacted by outliers at the extremes.

For the given dataset, IQR can be calculated as:

Arrange the dataset in ascending order:

[tex]5, 5, 6, 8, 10, 15, 18, 20, 20, 20, 20, 20, 20[/tex]

Find the median (Q2), i.e. the middle value of given dataset:

Median (Q2) = 15

Find the lower quartile (Q1), which is the median of the lower half of the dataset:

[tex]Q1 = Median of (5, 5, 6, 8, 10) = 6[/tex]

Find the upper quartile (Q3) i.e. median of the upper half of dataset:

[tex]Q3 = Median \;of (15, 18, 20, 20, 20, 20, 20) = 19[/tex]

[tex]IQR = Q3 - Q1 = 19 - 6 = 13[/tex]

Utilizing the IQR of 13, which represents the range between the 25th percentile (Q1 = 6) and the 75th percentile (Q3 = 19), would provide a more accurate measure of variability that is less impacted by outliers at the higher end of the data.

Answer: 3.610^5+4.810^4 in scientific notation is 4.08*10^5.

Step-by-step explanation: The initial step to convert 3.610^5+4.810^4 into scientific notation is to combine the two values.

The sum of 3610 multiplied by 10 to the power of 5 and 4810 multiplied by 10 to the power of 4 is equal to adding 3610 multiplied by 10 to the power of 4 and 4810 multiplied by 10 to the power of 4, resulting in 40.8 multiplied by 10 to the power of 4.

We can convert 40.8*10^4 to scientific notation by shifting the decimal point to the left until there is only one non-zero digit to the left of the decimal, and denoting the number of decimal places moved with a 10 exponent.

Rewording: When you raise 40.810 to the power of 4, the result is 4.0810 to the power of 5 when you add 1 to the exponent. This is equivalent to multiplying 4.08 by 10 and raising it to the power of 5.
