Considering the given discrete probability distribution, it is found that there is a 0.36 = 36% probability that Hugo buys fewer than 3 packs.

Researching on the internet, it is found that the discrete probability distribution for the number of packs that Hugo buys is given by:

The probability that he buys fewer than 3 packs is given by:

P(X < 3) = P(X = 1) + P(X = 2).

Hence:

P(X < 3) = P(X = 1) + P(X = 2) = 0.2 + 0.16 = 0.36.

There is a 0.36 = 36% probability that Hugo buys fewer than 3 packs.

Assuming it sells for $55.00 per share. Its effective annual (not nominal) rate of return is 7.47%.

Using this formula

Effective annual rate of return=[1+(Preferred quarterly dividend+Preferred stock price]^Periods per year-1

Where:

Periods per year =4

Preferred quarterly dividend=$1.00

Preferred stock price=$55.00

Let plug in the formula

Effective annual rate of return = [1+ ($1.00/$55.00)]^4 - 1

Effective annual rate of return=(1+0.018181818)^4-1

Effective annual rate of return=(1.018181818)^4-1

Effective annual rate of return =1.0747-1

Effective annual rate of return =0.0747×100

Effective annual rate of return = 7.47%

Therefore the Effective annual rate of return will be 7.47%.

The stopping Distance of the Car with the given parameters is; 17.43 m

We are given;

mass; m = 1 000 kg

speed; u = 16.7 m/s

Frictional force; F = 8000 N

distance, s  = ?

final velocity = 0 m/s (car stops)

Formula for final velocity is;

v² = u² + 2as

but a = negative (deceleration)

And F = ma

Thus;

a = F/m = 8000/1000

a = 8 m/s²

Thus;

0 = (16.7)² - 2(8)(s)

278.89 = 16s

An expression for the Ksp for hydroxyapatite would be written as follows:

                            Ksp =   [tex][(Ca^{++})^5][OH^{-}][(PO_4)^3][/tex]

In Chemistry, the solubility product constant (Ksp)​ can be defined as the equilibrium constant that describes a solid substance (solute) which is being dissolved in an aqueous solution.

This ultimately implies that, Ksp is typically used in chemistry to denote an equilibrium level at which a solute dissolves in an aqueous solution.

Mathematically, an expression to represent the solubility product constant (Ksp)​ for hydroxyapatite is written as follows:

The smallest positive integer n so that you can avoid ever having the exact same group of three members over all 365 days is; 11

if we have n people and we want to do groups of 5, the total number of different combinations is:

ⁿC₅ = n!/((n - 5)!5!)

By using the Brute force method, we have;

If n = 5,

c = 5,

Thus;

C₅ = 5

If n = 6,

c = 6,

Thus;

C₅ = 6

If n = 7,

c = 7,

Thus

C₅ = 21

If n = 8,

c = 8,

Then;

C₅ = 56

Now, If n = 9,

C = 9!/((9 - 5)!5!)

C = 126

We want to find the smallest n such that c > 365. Thus, C = 126 is too small.

Let's try n = 11;

C = 11!/(6! * 5!) =  462

This is greater than 365 and so we need at least 11 members in the club.

The wavelength of the sound wave if the frequency is increased to the given value is 0.44m.

Wavelength is simply the distance over which the shapes of waves are repeated. It is the spatial period of a periodic wave.

It is expressed as;

[tex]\lambda = \frac{v}{f}[/tex]

Where v is velocity and f is frequency.

Given the data in the question;

Speed of sound wave; [tex]v =\ ?[/tex]

Wavelength of sound wave b; [tex]\lambda _b = ?[/tex]

First, we calculate the velocity of the sound wave in air from sound wave a.

[tex]\lambda = \frac{v}{f}\\ \\1.76m= \frac{v}{196s^{-1}}\\\\v = 1.76m * 196s^{-1}\\\\v = 344.96m/s[/tex]

Now, we determine the wavelength of sound wave b using the velocity of sound wave in air calculated above.

[tex]\lambda = \frac{v}{f}\\ \\\lambda = \frac{344.96m/s}{784s^{-1}}\\\\\lambda = 0.44m[/tex]

Therefore, the wavelength of the sound wave if the frequency is increased to the given value is 0.44m.

The solution can be evaporated such that only 10mL of the solution remains in that way, we can have a solution of pH 12.00.

The pH refers to the degree of acidity or alkalinity of solution. We can obtain the concentration of each solution from the pH as follows;

At pH = 13;

[OH^-] = Antilog (-13) = 1 * 10^-13 M

At pH 12

[OH^-] = Antilog (-12) = 1 * 10^-12 M

Using the formula;

C1V1 =C2V2

1 * 10^-13 M * 100 mL = 1 * 10^-12 M * VmL

VmL = 1 * 10^-13 M * 100 mL/1 * 10^-12 M

VmL = 10mL

There is only one net force acting on the charge at the center of the circle that will only be subjected to a repulsive force from the charge is extant on the negative axis of x.

A line charge refers to the charge that is allocated along a curve that is one dimensional in nature such as a circle.

In physics experiments, line charges are used in wire chambers. Wire chambers are used for high-energy physics experiments.

In summary, the charges are put at equal distances around the circumference of the circle in the example.

Because the charges at the opposing ends of the circle are similar, they exert an equal-magnitude repelling force in the opposite direction on the charge at the center of the circle, thus balancing out the forces.

This is why there is only one net force acting on the charge at the center of the circle that will only be subjected to a repulsive force from the charge is extant on the negative axis of x.
