Answer:

the Rhine River is approximately 1216 km long

Step-by-step explanation:

a) If the Mississippi River is 19% longer than the Indus River, we can find its length by multiplying the length of the Indus River by 1.19:

Length of Mississippi River = 3200 km x 1.19 = 3808 km

Therefore, the Mississippi River is approximately 3808 km long.

b) If the Rhine River is 62% shorter than the Indus River, we can find its length by multiplying the length of the Indus River by 0.38 (100% - 62% = 38%):

Length of Rhine River = 3200 km x 0.38 = 1216 km

Therefore, the Rhine River is approximately 1216 km long.

Answer:

2026 to maximize the present value function.

Step-by-step explanation:

To find the year in which the timber should be harvested to maximize the present value function, we need to find the time t that maximizes the present value function A(t). We can begin by finding A(t):

A(t) = V(t)e^(-0.09t)

A(t) = 140,000e^(0.72√t) * e^(-0.09t)

A(t) = 140,000e^(0.72√t - 0.09t)

To maximize A(t), we need to find the critical points of A(t). We can do this by taking the derivative of A(t) and setting it equal to zero:

A'(t) = 140,000(0.36/√t - 0.09)e^(0.72√t - 0.09t) = 0

Simplifying this equation, we get:

0.36/√t - 0.09 = 0

0.36/√t = 0.09

√t = 4

t = 16

Therefore, the critical point of A(t) occurs at t = 16 years.

We can check that this is a maximum by taking the second derivative of A(t) and evaluating it at t = 16:

A''(t) = 140,000(-0.648/t^3 - 0.243/√t + 0.081)e^(0.72√t - 0.09t)

A''(16) = 140,000(-0.648/16^3 - 0.243/4√16 + 0.081)e^(0.72√16 - 0.09(16))

A''(16) ≈ -4,980.4

Since the second derivative is negative, we can conclude that t = 16 years corresponds to a maximum for the present value function A(t).

Therefore, the timber should be harvested in the year 2010 + 16 = 2026 to maximize the present value function.

Vera's location after three hours is thus 2,100 feet above sea level.

Division is a basic arithmetic operation used to find how many times one number (the divisor) is contained within another number (the dividend). The result of a division operation is the quotient. Division is often represented using the symbol "÷" or "/".  Sometimes division results in a remainder, which is the amount left over after dividing as much as possible.  Division is one of the four basic arithmetic operations, along with addition, subtraction, and multiplication. It is used in a wide variety of mathematical and real-world contexts, such as sharing equally, calculating rates, and solving equations.

Here,

To find Vera's location after three hours of climbing down the mountain, we first need to convert three hours into minutes. There are 60 minutes in one hour, so three hours is:

3 hours x 60 minutes/hour = 180 minutes

Vera descends at a rate of five feet per minute, so after 180 minutes, she will have descended:

180 minutes x 5 feet/minute = 900 feet

3,000 - 900 = 2,100

Therefore, Vera's location after three hours is 2,100 feet above sea level.

Points on the graph of the function are; (3, 2), and (4, 1)

Slope of the graph of the function = (1 - 2)/(4 - 3) = -1

Equation of the function is; y - 2 = -1·(x - 3) = 3 - x

y = 3 - x + 2 = 5 - x

y = 5 - x

y = f(x) = 5 - x

f(x) - 1 = 5 - x - 1 = 4 - x

The volume of the largest right circular cone that can be inscribed in a sphere of radius 18 cm is approximately 11622.85 cubic centimeters.

To find the largest right circular cone that can be inscribed in a sphere of radius 18 cm, we need to find the cone with the largest possible volume that can fit inside the sphere.

Let's assume that the apex of the cone is at the center of the sphere. Since the cone is a right circular cone, the base of the cone will lie on the surface of the sphere, forming a circle with radius equal to the radius of the sphere, which is 18 cm.

Let's call the height of the cone "h" and the radius of the base of the cone "r". Then we can use the Pythagorean theorem to relate the height, radius, and slant height (which is equal to the radius of the sphere):

r^2 + h^2 = (18 cm)^2

The volume of a cone can be expressed as V = (1/3)πr^2h. We want to maximize this expression subject to the constraint above. We can use the constraint to eliminate one of the variables in the volume expression, then differentiate with respect to the remaining variable and set the derivative equal to zero to find the maximum.

From the constraint, we can solve for h^2:

h^2 = (18 cm)^2 - r^2

Substituting into the volume expression, we get:

V = (1/3)πr^2(18 cm - sqrt(r^2 + h^2))

Simplifying this expression, we get:

V = (1/3)πr^2(18 cm - sqrt((18 cm)^2 - r^2))

Differentiating with respect to r, we get:

dV/dr = (1/3)π(36 cm)r - (1/3)πr^3/sqrt((18 cm)^2 - r^2)

Setting this equal to zero and solving for r, we get:

r = (18 cm)/sqrt(2)

Substituting this value of r back into the expression for h, we get:

h = (18 cm)/sqrt(2)

Finally, substituting these values of r and h into the expression for the volume, we get:

V = (1/3)π((18 cm)/sqrt(2))^2((18 cm) - sqrt(((18 cm)/sqrt(2))^2 + ((18 cm)/sqrt(2))^2))

Simplifying this expression, we get:

V ≈ 11622.85 cubic centimeters

Answer:

Step-by-step explanation:

If the generation time of bacteria is 30 minutes, it means that in every 30 minutes, the number of cells will double. Let No = 100 be the initial number of cells, and n be the number of generations at that point.

Using the given formula N1 = N x 2^n, we can find the number of cells at any given time t, in minutes.

For t = 30 minutes:

The number of generations in 30 minutes is 1 (since generation time is also 30 minutes)

N1 = 100 x 2^1 = 200 cells

For t = 60 minutes:

The number of generations in 60 minutes is 2 (since generation time is 30 minutes)

N1 = 100 x 2^2 = 400 cells

For t = 90 minutes:

The number of generations in 90 minutes is 3 (since generation time is 30 minutes)

N1 = 100 x 2^3 = 800 cells

For t = 120 minutes:

The number of generations in 120 minutes is 4 (since generation time is 30 minutes)

N1 = 100 x 2^4 = 1600 cells

Therefore, after 30 minutes, the number of cells will be 200, after 60 minutes it will be 400, after 90 minutes it will be 800, and after 120 minutes it will be 1600.

The mean number of employees who work on a given day is less than the median number of employees who work on a given day and option C is correct.

In statistics, we frequently choose a representative value that roughly describes the full collection to represent a set of data. The label "measure of central tendency" denotes that this representative value is one around which the data is centred. The mean, median, and mode are these central tendencies.

Mean = sum of all values/frequency

Mean = (20(0.01) + (21(0.1)) + (22(0.1)) + (23(0.4)) + (24(0.3))

mean is 22.7.

The median id the value of X for which P(X<x) is greater than or equal to 0.5 and P(X>x) is greater than or equal to 0.5. Therefore, median is 23.

Mode is the value of X having maximum probability. Therefore, mode is 23.

Step-by-step explanation:

To simplify this expression, we need to apply the order of operations (PEMDAS):

First, we evaluate the expression inside the parentheses: 9 ÷ 3 = 3.

Then, we add 6 + 3 = 9.

Finally, we divide 1,629 by 9 to get the answer:

1,629 ÷ 9 = 181.

Therefore, 1,629 ÷ (6 + 9 ÷ 3) simplifies to 181.

The standard error tells us how much we can expect the sample proportion to vary from the true proportion in repeated samples of the same size. Option (d) correctly states that "In samples of size 100 from this school, the sample proportion of students who bring a reusable water bottle from home typically varies by about 0.048 from the true proportion." This means that if we were to take many samples of 100 students from the same school and calculate the proportion of students who bring a reusable water bottle from home in each sample, about 95% of the sample proportions would fall within +/-0.048 of the true proportion.

The correct option is (d) "In samples of size 100 from this school, the sample proportion of students who bring a reusable water bottle from home typically varies by about 0.048 from the true proportion."

The standard error of the sample proportion can be calculated using the formula:

SE = √[p*(1-p) / n]

where p is the sample proportion and n is the sample size.

In this case, the sample proportion is 37/100 = 0.37 and the sample size is 100. Plugging in these values, we get:

SE = sqrt[0.37*(1-0.37) / 100] = 0.048

In mathematics, inequalities specify the connection between two non-equal numbers. Equal does not imply inequality. Inequality is a mathematical statement that uses the inequality symbol to illustrate the relationship between two expressions. An inequality symbol has non-equal expressions on both sides. It indicates that the phrase on the left should be bigger or smaller than the expression on the right, or vice versa. Literal inequalities are relationships between two algebraic expressions that are expressed using the inequality symbols. Typically, we use the "not equal" sign to indicate that two values are not equal. However several inequalities are utilised to compare the numbers, whether it is less than or higher than.
