Answer:

The number of terms in the series is (n-m+3)/3, where n is the last term in the series.

Therefore, the solutions to the simultaneous equation are (x, y) = ((5 + √(21))/2, (5 - √(21))/2) and (x, y) = ((5 - √(21))/2, (5 + √(21))/2).

To solve the simultaneous equation 1÷x + 1÷y = 5, 1÷y - 1÷x = 1, we can use the substitution method. Here are the steps to solve the equation:
1. Rearrange the first equation to get 1÷y = 5 - 1÷x
2. Substitute this into the second equation to get 1÷(5 - 1÷x) - 1÷x = 1
3. Multiply both sides by x(5 - 1÷x) to get x - (5 - 1÷x) = x(5 - 1÷x)
4. Simplify and rearrange to get x² - 5x + 1 = 0
5. Use the quadratic formula to solve for x: x = (-(-5) ± √((-5)² - 4(1)(1)))÷(2(1)) = (5 ± √(21))/2
6. Substitute the values of x back into the first equation to find the corresponding values of y: y = 1÷(5 - 1÷((5 + √(21))/2)) = (5 - √(21))/2 and y = 1÷(5 - 1÷((5 - √(21))/2)) = (5 + √(21))/2

The bell shaped distribution is the continuous probability distribution with a specific shape resembling a symmetrical

Bell-shaped distribution is a statistical term that describes a continuous probability distribution with a specific shape resembling a symmetrical, bell-shaped curve. This distribution is also known as the normal distribution or Gaussian distribution.

The bell-shaped distribution is characterized by its mean, which is the center of the curve, and its standard deviation, which measures the spread of the distribution. The curve is symmetric, meaning that the probabilities of values to the left and right of the mean are equal.

In a bell-shaped distribution, the majority of data points cluster around the mean, with fewer points as you move further away from the mean. The tails of the distribution extend infinitely in both directions, although the probability of observing values far from the mean becomes increasingly small.

The normal distribution is used in many fields, including science, engineering, and finance, to model real-world phenomena that are influenced by many small, random factors.

With the help of using Pythagoras Theorem, we find out the value of C in this abc right angled triangle. A = 12units, B = 5 units and C = 13 units.

assuming that A and B are the lengths of the legs of a right angled  triangle and we need to find the length of the hypotenuse (c), we can use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the legs. Using this theorem, we can write:

c² = a² + b²

Substituting the given values, we get:

c² = 12² + 5²

c² = 144 + 25

c² = 169

c = √169

c = 13

Therefore, the length of the hypotenuse (c) is 13 units. the Pythagorean theorem is a mathematical formula that relates to the sides of a right angled triangle. It states that in a right angled triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides (legs). The Pythagorean theorem is named after the ancient Greek mathematician Pythagoras and is widely used in geometry and other fields of mathematics. It is a fundamental concept in trigonometry, which deals with the relationships between the angles and sides of triangles.

Amount Luigi received per day is $3,384.4 and Amount Luigi received per hour is about $141

Profit is the difference between the revenue that an economic entity has received from its outputs and the total cost of its inputs.

The amount Mario invests = $500,000

Amount Luigi invests = $350,000

The ratio in which the profit was split after their first year = Within the same ratio of their initial investments

The amount of profit made by the business = $3 million

The ratio of their initial investment = 500,000 : 350,000 = 10 : 7

Therefore, the ratio in which the profit is split = 10 : 7

The amount Luigi received in a year = (7/(10 + 7)) × 3 = 1235294 2/17

The time unit conversion from year to day is presented as follows;

Number of days in a year = 365 days

The amount Luigi received per day = (1235294 2/17)/365 = 3384 456/1241

= 3384.4

The amount Luigi received per day = $3,384.4

b) The number of hours in a day = 24 hours

Amount Luigi received per hour = (3384 456/1241)/24 = 141 19/1241

141 19/1241 = 141

The amount Luigi received per hour is about $141

where r is the radius of the cylinder and h is its height.

In this case, the radius is x+3 and the height is x+11, so we can substitute these values into the formula:

V = π(x+3)^2(x+11)

Simplifying this expression, we have:

V = π(x^2 + 6x + 9)(x+11)

V = π(x^3 + 17x^2 + 69x + 99)

Therefore, the volume of the cylinder with radius x+3 and height x+11 is π(x^3 + 17x^2 + 69x + 99) cubic units.

From the given figure,
Applying the trig ratios in triangle ABC to evaluate BC,
tan60 = 12/BC
BC = 12/√3
BC = 4√3

Now,
BC = AD and ∠EAD = 90 - ∠ABC  [∠ABC = ∠ADC]
So ∠EAD = 90 - 60 = 30

Again in triangle ADE,
tan60 = ED/AD
ED = AD/√3
ED = 4√3/√√3

No, the comparison is not expected to be fair. The two groups being compared are not selected randomly from the same population

A population is a group of organisms of the same species that live in the same geographic area and are capable of interbreeding. The term "population" can refer to a group of animals, plants, bacteria, or any other type of living organism.

Populations can vary in size from just a few individuals to millions or even billions. The size of a population can be influenced by a number of factors, including birth rates, death rates, immigration, and emigration.

Populations also have characteristics that define their genetic makeup, such as the frequency of particular alleles or genes. This genetic diversity can influence the ability of a population to adapt to changes in its environment or to recover from disturbances, such as disease outbreaks or natural disasters.

Understanding population dynamics is important for fields such as ecology, conservation biology, and public health, as it can help us to better manage and protect populations of organisms, including our own.

Assume that there are {x} students in each van and {y} students in each bus. We can write the system of equations as -

3x + 7y = 263

12x + 3y = 177

Now, we can write -
