The length of the rectangle in centimeters is 15.60 cm.

The correct way to report the length of the rectangle in centimeters is 15.60 cm. To calculate the length of the rectangle, we must first calculate the distance between the two edges of the rectangle. To do this we can use the formula Distance = Final Position - Initial Position. Therefore, the distance between the two edges of the rectangle is 15.600 cm - 0 cm = 15.600 cm. This is the length of the rectangle, so the correct way to report the length of the rectangle in centimeters is 15.60 cm.

Answer:

3/2 of a mile

Step-by-step explanation:

The equation is 1/2 times something = 3/4 (because length times width is area)

you would divide 1/2 on both sides to get an unknown number(that represents the width)

3/4 divided by 1/2 is 3/2 of a mile !

Answer:

length=9

width=4m

Step-by-step explanation:

Let the width of the rectangle be, x and the length be, x+5

perimeter=2(L+W)

Answer:

The marginal profit function can be found by subtracting the marginal cost from the marginal revenue. The marginal cost is given by the derivative of the cost function, and the marginal revenue is given by the derivative of the revenue function.

The derivative of the cost function is:

C'(x) = dC(x)/dx = 0.9

The derivative of the revenue function is:

C'(x) = dC(x)/dx = 0.9

The derivative of the revenue function is:

R'(x) = dR(x)/dx = 9 - 0.04x

Therefore, the marginal profit function is:

P'(x) = R'(x) - C'(x) = 9 - 0.04x - 0.9 = 8.1 - 0.04x

The cost of carpeting a rectangular floor measuring 9 feet by 18 feet is 18 square yards x 12.75 = 228.50.  If needed, this can be rounded to the nearest penny, which is 228.50.

The formula to calculate the cost of carpeting a rectangular floor is Area of the floor x Cost of carpet per square yard.

The area of the floor is calculated by multiplying the length and the width, which in this case is 9 feet x 18 feet = 162 square feet.

To convert 162 square feet into square yards, divide 162 square feet by 9, which equals 18 square yards.

Therefore, the cost of carpeting a rectangular floor measuring 9 feet by 18 feet is 18 square yards x 12.75 = 228.50.  If needed, this can be rounded to the nearest penny, which is 228.50.

When two finite populations are connected by migration , then (b) Fst decreases to 0 .

The Fixation Index denoted as Fst ,  is a measure of population differentiation, which is used to quantify the level of genetic differentiation between two populations.

The Fst ranges from 0 to 1, where 0 indicates complete gene flow between two populations and 1 indicates complete genetic isolation.

If the migration rate is 2% per organism per generation, over time this will lead to a reduction in genetic differentiation between the populations, and the Fst value will decrease towards 0.

This is because the exchange of genetic material will reduce the amount of variation that is unique to each population, which leads to an increase in the genetic similarities between the populations.

The given question is incomplete , the complete question is

What happens to Fst when two finite populations are connected by migration (say 2% chance of migration per organism per generation, and no selection) ?

Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.

Given that, an expression (8+√12) / (5+√3) we need to convert it into

(a+√3) / b, where, a and b are integers.

The given expression is (8+√12) / (5+√3)

Rationalizing the expression by multiplying the numerator and denominator by changing the sign of the denominator, (5-√3)

Therefore, (8+√12) / (5+√3)

= (8+√12) / (5+√3) × (5-√3) / (5-√3)

= (40 - 8√3 + 5√12 - √36) / 5²-√3²   [a²-b² = (a+b)(a-b)}

= (40 - 8√3 + 5× 2√3 - 6) / (25-3)

As percent did the number of full-time students enrolled at college t increase from the fall of 1999 to the fall of 2000 is 25%.

A percentage is a fraction of a whole number expressed as a fraction of 100. It is often used to describe the change in a quantity over time or between different groups.

There were 50 more full-time students enrolled in the fall of 2000 than in the fall of 1999, we can calculate the change in the number of full-time students as follows:

Change in full-time students = 50

To calculate the percentage change, we need to know the initial number of full-time students in the fall of 1999. This information is not provided, so we will use the information that the total number of students enrolled at College T increased by 5 percent from the fall of 1999 to the fall of 2000.

Let's call the total number of students enrolled at College T in the fall of 1999 "x". Then, the total number of students enrolled at College T in the fall of 2000 would be x + 5% of x.

x + 5% of x = x + 0.05x = 1.05x

To find the number of full-time students in the fall of 2000, we can subtract the change in full-time students from the total number of students enrolled at College T in the fall of 2000:

Number of full-time students in fall of 2000 = 1.05x - 50

To calculate the percentage change, we divide the change in full-time students by the initial number of full-time students and multiply by 100:

Percentage change = (50 / x) * 100

Where the value of x as 2000, then the percentage is

=> (50/2000) * 100 = 25%.

The given statement: The standard deviation is a resistant measure of spread is true.

Standard deviation is the measure of how spread out numbers are. It is a measure that is used to quantify the amount of variation or dispersion of a set of data values.

The standard deviation is a metric that reveals how much variance from the mean there is, including spread, dispersion, and spread. A "typical" variation from the mean is shown by the standard deviation. Because it uses the data set's original units of measurement, it is a well-liked measure of variability. When data points are closely spaced from the mean, there is a little variation, and when they are far spaced from the mean, there is a large variation. The standard deviation determines how much the data deviate from the mean.

When outliers are included, resistant statistics don't change (or vary very little). Resistance does not imply that anything is immobile; that would be "immovable." It implies that your results could fluctuate a bit, but not much.

Graph of the equation y-4=0.75(x-1) is in the attachment.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

The given  equation is y-4=0.75(x-1)
