The time that it took Raj's older brother to complete his homework was 1 ¹ / ₄ hours

The time that it would take for Raj to complete the homework is 5/6 hours. His older brother would do it in 1 1/2 times as long.

The first thing to do is to convert this to an improper fraction:

= 1 1/2

= (2 x 1 + 1) / 2

= 3 / 2

The time it would take Raj's brother is therefore:

In 2years time, Lamar will be 18years old by application of an algebraic expression x for the unknown value.

Algebra is the branch of mathematics that helps to represent problems or unknown values in the form of mathematical expressions.

Algebraically, let us represent the age of Malcolm with the unknown value x

then the age of Lamar will be 4x

In 2years time;

Malcolm's age = x + 2

Lamar's age = 3(x + 2) {3times as old as Malcolm}

Also

Lamar's age = 4x + 2 {Lamar's age plus 2years}

So

4x + 2 = 3(x + 2)

open bracket by expansion

4x + 2 = 3x + 6

collect like terms

4x - 3x = 6 - 2

x = 4

Hence, substituting the known value of x in the algebraic expressions of x for Malcolm's age and 4x for Lamar's age, we have 4years and 16years respectively. And in 2years time Lamar will be 18years

Finally, for x = 16 (the corresponding y is the height of the candle after 16 hours):

The graph rises parabolically. The rise in the value is not perfectly parabolic, but the increase can be structured as parabolic.

The general equation of a parabola is given by a quadratic equation as-

y = ax² + bx + c. It has a degree of [2] and has two possible roots.

We have the following table -

Days after posting [x] →    1     2     3     4    5    6

Unique daily views [y] →   5    8   13   20  29  40

Refer to the graph attached. It can be seen that, the graph is a parabola. Although the rise in the value is not perfectly parabolic, but the increase can be structured as parabolic. Mathematically, the equation of the parabola can be written as -

y = ax²

The parabola is wide open {not close to y - axis}, this signifies that the value of [a] is in decimals. If we make a estimate, it would be almost [a] = 1/88 for the mentioned data.

Therefore, the graph rises parabolically. The rise in the value is not perfectly parabolic, but the increase can be structured as parabolic.

The value of the radius that minimizes the amount of Aluminium is 4.64 cm and it gives the local minimum of the function

From the question, the volume of the aluminium is given as

Volume = 200pi cm^3

Rewrite this volume properly using the correct symbols and units

So, we have the following representation

Volume = 200π cm³

Solving further, we make use of the volume of a cylinder (i.e. a can)

The volume of a sphere is represented as

V = πr²h

Substitute Volume = 200π cm³ in

πr²h = 200π

Make h the subject in the above equation

This gives

h = 200π/πr²

Cancel the common factors

h = 200/r²

The surface area of a can is

A = 2πr(h + r)

So, we have

A = 2πr(200/r² + r)

This gives

A = 400π/r + 2πr²

Differentiate the function

This gives

A' = -400π/r² + 4πr

Set the differentiated function to 0

-400π/r² + 4πr = 0

So, we have

-400π/r² = -4πr

Cross multiply

-400π = -4πr³

Divide through by -4π

r³ = 100

Take the cube roots

r = 4.64

Hence, the radius that given minimum material is 4.64 cm

The theorem that states that the sampling distribution of the sample mean is approximately normal when the sample size n is reasonably large is known as the Central Limit Theorem

The Central Limit Theorem is a statistical theorem that states that, given a sufficiently large sample size, the distribution of the mean of any sample will be approximately normal, regardless of the shape of the distribution from which the sample was drawn.

In other words, the theorem states that the mean of a large sample will be close to the mean of the population, and that the standard deviation of the distribution of the sample mean will be small.

The theorem is important because it provides a way to approximate the distribution of any sample statistic, as long as the sample size is large enough. This is useful because many statistical tests, such as hypothesis tests and confidence intervals, require that the data be normally distributed.

The theorem is also important because it provides a way to quantify the amount of error that is introduced when a sample is used to estimate a population parameter. This is known as the standard error, and it is equal to the standard deviation of the distribution of the sample mean divided by the square root of the sample size.

The Central Limit Theorem is one of the most important theorems in statistics, and it is widely used in many different fields.

To answer this question, we need to have into account the following:

1. In the context of interval notation, the word "or" can be represented by the symbol "U".

2. We need to rearrange the inequality -x > 6 in a way that we have positive x.

We can proceed as follows:

We can express the inequality in this way because it expresses all of the values greater than 2, and these values tend to the positive infinity. We have parenthesis here since the values are not equal to 2 (only greater than 2).

If we multiply both sides of the inequality by -1, we need to reverse the direction of the inequality as follows:

Now, we have all of the values less than -6, not equal, and because of this, we have to use parenthesis:

Therefore, we can say that:
