A) What is the probability that a 13-card bridge hand contains i) All 13 hearts? ii) 13 cards of the same suit? iii) Seven spades and six clubs?

Using the **hypergeometric **distribution, the **probabilities **are given as follows:

**a)** All 13 hearts: [tex]1.57 \times 10^{-12}[/tex]

**b) **13 cards of the same suit: [tex]6.30 \times 10^{-12}[/tex]

**c) **Seven spades and six clubs: [tex]5.4 \times 10^{-9}[/tex]

The **formula **is:

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}[/tex]

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

The **parameters **are:

The **general parameters** in this problem are given as follows:

In **item i**, there are 13 hearts in a standard deck, hence k = 13 and the **probability **is P(X = 13), hence:

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}[/tex]

[tex]P(X = 13) = h(13,52,13,13) = \frac{C_{13,13}C_{39,0}}{C_{52,13}} = 1.57 \times 10^{-12}[/tex]

For** item ii**, we consider the same context of item i, just now we can consider any of the** four types** of cards, hence:

[tex]p = 4 \times 1.57 \times 10^{-12} = 6.30 \times 10^{-12}[/tex]

For **item iii**, we want:

Hence the **probability **is given as follows:

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}[/tex]

[tex]P(X = 7) = h(7,52,13,13) = \frac{C_{13,7}C_{13,6}}{C_{52,13}} = 5.4 \times 10^{-9}[/tex]

Una masa de 2,0 kg está unida al extremo de una cuerda de 5,0 m. La masa se mueve en una trayectoria circular sobre una superficie horizontal sin rozamiento. Si la resistencia a la rotura de la cuerda es 40 N, la máxima velocidad lineal con la que se puede hacer girar la masa sin que se rompa la cuerda es aproximadamente

La maxima **velocidad lineal** de la **masa** con la que se puede girar la **masa** es igual a 40 newtons.

¿Cuál es la velocidad lineal máxima permitida por la masa en movimiento circular uniforme?

En este problema tenemos el caso de una masa (m), en kilogramos, conectada a una **cuerda** y que experimenta un **movimiento circular uniforme**, en donde la **partícula** describe un movimiento a **velocidad lineal** constante (v), en metros por segundo, debido a una **aceleración radial** que está en la forma de **tensión** (T), en newtons, a través de la cuerda. En consecuencia, la velocidad máxima permitida es determinada a partir de las **leyes de Newton**:

T = m · (v² / R)

Donde:

m - Masa, en kilogramos.v - Velocidad lineal, en metros por segundo.R - Longitud de la cuerda, en metros.Si sabemos que m = 2 kg, R = 5 m y T = 40 N, entonces la maxima velocidad lineal permitida es:

40 N = (2 kg) · v² / (5 m)

v = 10 m / s

La maxima **velocidad lineal** permitida es igual a 10 metros por segundo.

A triangle is composed by **three **internal angles, and the **sum **of it's **measures **is of 180º.

In the context of this problem, the **measures **are given as follows:

Considering that the sum is of **180º**, we can build an equation to** solve for x** as follows:

3x + 10 + 6x + 2x + 5 = 180

11x + 15 = 180

The **measure **of the **angles **are;

It is important to note that the sum of angles in a triangle is supplementary.

Also, **supplementary angles** are defined as pair of angles that sum up to 180 degrees.

Two angles are termed supplementary when they add up to give 180 degrees.

Since, we have that the** sum** of the interior angles of a **triangle** are supplementary, then,

Angle A + Angle B + Angle C = 180 degrees

Given the values as;

m∠ A = 3x + 10m∠ B = 6xm∠ C = 2x + 5Now, put or substitute the values into the formula

3x + 10 + 6x + 2x + 5 = 180

collect like terms

3x + 6x + 2x = 180 - 15

Add or subtract like terms

11x = 165

Make 'x' the subject by dividing both sides by the coefficient of x, we have;

11x/11 = 165/11

Find the quotient

x = 15

But we have to find the angles by substituting the value of x

m∠ A = 3x + 10 = 3(15) + 10 = 55 degrees

m∠ B = 6x = 6(15) = 90 degrees

m∠ C = 2x + 5 = 2(15) + 5 = 35 degrees

Hence, the **angles **are 55 degrees, 90 degrees and 35 degrees respectively.

Josie’s best friend is getting married and she wants to buy her something from her online wedding registry. She wants to buy some sets of dishes (d) that cost $35 each. Because she’s buying online, she must pay a shipping fee of $10. Josie wants to spend $150 or less. How many sets of dishes can Josie buy?

**Answer:**

Josie can by 4 dish sets.

**Step-by-step explanation:**

subtract 10 from both sides:

35d + 10 - 10 = 150 - 10

35d = 140

divide both sides by 35:

35d/35 = 140/35

d = 4

What is the y-intercept? Select the correct choice below and fill in any answer boxes within your choice.

We have the relation:

**y = 4x + 3**

Since the slope (4) and the y-intercept (3) were already found, we need now to graph this line.

In order to do so, we can find two points belonging to this line and then draw a line that passes through those points.

The first point can be **(0, 3)**, since we know that the y-intercept is 3, i.e., y = 3 for x = 0.

Now, to find a second point we can choose a value for x, let's say x = 1, and use it in the equation of the line to find the corresponding value of y:

**y = 4x + 3 , x = 1**

**y = 4 * 1 + 3**

**y = 4 + 3**

**y = 7**

So, **(1, 7)** is another point we can use.

Jacob and Diego are racing to see who can get his community service hours for scouting completed first. Jacob, who has already completed 50 hours, plans to volunteer for 5 hours per week going forward. Diego hasn't started yet, but plans to dedicate 6 hours per week to his volunteer project from now on. Before too long, the boys will be tied, with the same number of volunteer hours. How long will that take?

**Number **of weeks required before Jacob and Diego will be tied in the race to complete community service **hours **for scouting is equal to **50 weeks.**

As given in the question,

Let **number** of weeks be represented by a variable *x*.

Jacob plans to devote 5 hours per week from now onwards. Hence his volunteer hours will cumulate to 5*x*+50 as he has already completed 50 weeks.

Diego plans to devote 6 hours per week from now onwards. Hence his volunteer **hours** will cumulate to 6*x*.

For Jacob and Diego to tie in the race, their volunteer hours should be equal. Translating this into a linear algebraic equation,

6*x* = 5*x*+50

=> 6*x*-5*x* = 50

=> *x* = 50

Silver has been regarded as something precious for thousands of years. By 700 BCE, it was used to make coins. The production of silver grew over the centuries, but when Europeans first went to America, silver began to be used in many new and different ways. By the 19th century, nearly 120 million troy ounces were being produced annually. Now, more than 5000 years after ancient cultures first began to mine this precious metal, an average of 671 million troy ounces is mined every year. In earlier times, silver was thought to have magical properties and it was considered to be useful in keeping bad spirits away. Nowadays, most people think of silver in relation to ornaments. But it is significant for its antibacterial properties too. The ancient Phoenicians kept water, wine and vinegar in silver vessels to ensure freshness. It is only recently, however, that scientists have discovered how silver works. Quite simply, silver destroys the ability of bacteria to form the chemical bonds which are essential to their survival. When bacteria and silver come into contact, the bacterial cells fall apart. Today, there are bandages and ointments that use silver as an active ingredient. Silver promotes the growth of new cells, which in turn increases the rate of healing. This makes silver especially valuable for treating burns and wounds. Another key use for silver is in the millions of water purifiers that are sold each year. Silver prevents bacteria from building up in filters so that they can work effectively. Research has shown that silver, together with oxygen, cleans water. This means that other chemicals, such as chlorine, do not have to be used. Silver is therefore starting to be added to water purification systems in hospitals, community water systems and swimming pools. Scientists hope that silver will be able to be used in helping to produce clean drinking water in countries where water-borne illness is a problem. Current research shows that this use of silver is an exciting development for the global water supply. In the past, silver was often used to decorate places of worship, and many people saw it when they went to pray. Today, there is probably much more silver around us, but we do not necessarily see it. For example, every time you travel in a motor vehicle you are surrounded by pieces of silver. Every electrical action in a modern car is activated with silver-coated contacts. Basic functions such as starting the engine and opening power windows .all need a special switch that has a silver covering. Another important feature for our driving safety is the silver-ceramic lines fitted into the rear window. The heat created by these lines clears the rear window of mist and ice so that we can see clearly out of it. Silver is just as valuable today as it has been throughout human history.
