Answer:Square Root Formula

The square root formula of a number, x is given as,

√x = x1/2

Suppose, x is any number such that, x = y × y, the formula to calculate the square root of x will be,

√x = √(y × y) = y

where, y is the square root of any number x. This also means that if the value of y is an integer, then x would be a perfect square.

Step-by-step explanation:

The factors of the given expression would be = (x + 2), (x – 3) and (x + 5).

Factorisation of equations is defined as the expression of a given equation as a product of several other factors.

From the equation given; x³ 4x² 11x 30. it's factorisation would be done by getting the first root by trial and error method∶

Since the sum of the coefficients is not zero, 1 is not a root

Let x = -2

⇒ -8 + 16 + 22 – 30 = 0

∴ -2 is or (x + 2) is a factor

Dividing x3 + 4x2 – 11x – 30 by (x + 2)

Quotient = x2 + 2x – 15

⇒ x2 + 5x – 3x – 15 = 0

⇒ x (x + 5) – 3 (x + 5) = 0

⇒ (x – 3) (x + 5) = 0

Other factors are (x – 3) and (x + 5)

∴ (x + 2), (x – 3) and (x + 5) are the roots of the equation

Reason 1: Distributive Property

The 1/4 x was distributed to each term in the parentheses.

Reason 2: Commutative Property

The individual factors were moved around to put numbers next to numbers and variables next to variables.  (Technically the associative property was also used, to break down the previous parentheses, but I don't think your teacher is thinking about that.)

What is the property of commutativity?

The rule governing the ordering of variables is the commutative property. It states that the order of the variables does not influence the final answer when they are added or multiplied.

What is the property of associativity?

The associative feature of real numbers relates to grouping variables. It states that altering the grouping of variables added to or multiplied by one another has no effect on the output.

In mathematics, what is a distributive property?

This property states that multiplying the sum of two or more addends by a number yields the same result as multiplying each addend separately by the number and then putting the resulting products together.

First Argument: Distributive Property

[tex]\frac{1}{4x}[/tex]was allocated to each phrase between the parenthesis.

Reason 2: Property of Commutation

The individual elements were rearranged in order to place numbers alongside numbers and variables alongside variables. (Technically, the associative property was also utilized to separate the preceding parenthesis, although I doubt your teacher is aware of this.)

If all three sides of one triangle are equal to the corresponding three sides of the second triangle, then it is known as the SSS triangle congruency theorem.

The SSS rule states that two triangles are said to be congruent if their respective corresponding three sides are equal.

If all three sets of comparable sides are present, the triangles are congruent.

Using congruence, the side-side-side shortcut can be used (SSS).

Another shortcut is side-angle-side (SAS), which makes use of two sets of sides and an angle between them that is known to be congruent.

Therefore, if all three sides of one triangle are equal to the corresponding three sides of the second triangle, then it is known as the SSS triangle congruency theorem.

As pert the t-test there is sufficient evidence that the average family size in this school district differ from the national average.

Let us assume null and alternate hypothesis.

H₀ = Average family size is 3.18

Hₐ = Average family size is not 3.18

The value of t = (Sample Mean - 3.18) / s/√n

where,

Sample Mean = 3.83

n = 24

s = 1.43

So, t = (3.83 - 3.18) / (1.43 / √24)

t = 2.2268

Degree of freedom = n - 1 = 23

For a second order differential equation t²y'' - 4ty' + 6y = 0, general solution is of the form y(t) = c₁t² + c₂t³, so another solution other than y₁(t) = t² is y₂(t) = t³.

Given solution to t²y'' - 4ty' + 6y = 0 is

y₁(t) = t²

Using the method of reduction of order, let us assume, y₂(t) = v(t)y₁(t) is a solution to t²y'' - 4ty' + 6y = 0 for suitable choice of v(t). So,

y₂ = vt²

y₂' = 2vt + t²v'

y₂'' = 2v + 2tv' + 2tv' + t²v''

y₂'' = 2v + 4tv' + t²v''

Substituting this

t²×( 2v + 4tv' + t²v'') - 4t×(2vt + t²v') + 6×(vt²) = 0

t⁴v'' = 0

v'' = 0

v' = c, c is a constant

v = ct

Therefore, y₂(t) = ct×t²

Poisson distribution is applied for the case where the events occur in a specific period of time with constant rate.

The given case belongs to Poisson distribution,

It can be solved as follows,

(a) The probability of exactly 8 calls can be obtained as,

P(Exact 8 calls) =  [tex]e^{-\lambda} \lambda^{x}/x![/tex]

Where x = 8 and λ = 2.1 × 5 = 10.5.

Then, the probability is  obtained as,

⇒ e⁻⁸ × 10.5⁸/8!

⇒ 0.1009

It implies that if 100 calls are selected randomly for the interval of 5 minute, 10 calls can be expected.

(b)  The probability of less than 8 calls can be obtained as

P(Less than 8) = [tex]\sum_{x =1}^{7}e^{-\lambda}\lambda^{x}/ x![/tex]

⇒ P(Less than 8) = 0.1785
