An experiment consists of dealing 7 cards from a standard​ 52-card deck. What is the probability of being dealt exactly 4 face cards​?

Answers

Answer 1

Answer:

The probability that the first card is a heart is 13/52

For the second card it is 12/51 (There are only 51 cards and only 12 of them are in the heart suit.)

For the third card it is 11/50

4th card 10/49

5th card 9/48

6th card 8/47

7th card 7/46

 

The total probability of all of these events occurring is the product of each individual probability.

 

So, the answer is (13 * 12 * 11 * 10 * 9 * 8 * 7) / (52 * 51 * 50 * 49 * 48 * 47 * 46)

 

which equals exactly 33 / 2,572,780 or roughly 1 chance in about 77,963

What is the equation in point slope form of the line that passes through the point (3, 1) and has a slope of –2?


Drag and drop the appropriate number, symbol, or variable to each box.

Answers

Answer:

y - 1 =  -2(x - 3)

Step-by-step explanation:

Given the point, (3, 1) and the slope of –2:

Let  (x₁, y₁) = (3, 1)

slope: m = -2

Substitute these values into the following point-slope form:

y - y₁ = m(x - x₁)

y - 1 = -2(x - 3)  ⇒ This is the point-slope form.

Equivalent Expression:  [tex]\displaytext\mathsf{\frac{a^7}{b^8}}[/tex]

Step-by-step explanation:

Given the exponential expression,  [tex]\displaystyle\mathsf{\frac{a^{12}\:b^{-3}}{a^{5}\:b^{5}}}[/tex]:

We could use the Quotient Rule of Exponents where it states that:

[tex]\displaystyle\mathsf{\frac{a^m}{a^n}\:=\:a^{(m\:-\:n)}}[/tex]

Since we have the variables, a and b as the base, we could simply apply the Quotient Rule and subtract their exponents.

[tex]\displaystyle\mathsf{\frac{a^{12}\:b^{-3}}{a^{5}\:b^{5}}\:=\:a^{(12\:-\:5)}\:b^{(-3\:-\:5)}}[/tex]

[tex]\displaytext\mathsf{=\:a^{7}\:b^{-8}}[/tex]

Next, we must transform the negative exponent of base, b, into positive by applying the Negative Exponent Rule, where it states that:

[tex]\large\text{$ a^{-n}\:=\:\frac{1}{a^{n}} $}[/tex]

Applying the Negative Exponent Rule will result in the following exponential expression:

[tex]\LARGE\text{$ a^{7}\:b^{-8}\:=\:[a^{7}\:\times\:\frac{1}{b^8}]\:=\:\frac{a^7}{b^8} $}[/tex]

Therefore, the equivalent expression is:  [tex]\LARGE\text{$ \frac{a^7}{b^8} $}[/tex].

Tessa wants to install a zipline between two trees. The zipline will be strung between the trees at points 42 feet and 3 feet high. Suppose the trees are 60 feet apart. What is the length of the zipline to the nearest tenth of a foot

Answers

The length of the zipline is found using Pythagoras's theorem, which gives

the length of the hypotenuse side of a right triangle.

Length of the zipline is approximately 71.56 feet

Reasons:

Height at which the zipline will be tied to one of the trees = 42 feet

Height at which the zipline will be tied to the other tree = 3 feet

The distance between the trees = 60 feet

Required:

The length of the zipline

Solution:

The length of the zipline is found as follows;

Taking one of the trees to be at the origin, the coordinates of one of the tying point = (0, 42)

The coordinates of the other tying point = (60, 3)

The in the imagined right triangle formed by the zipline and the distance

between the trees, the length of the zipline is given by Pythagoras theorem

as follows;

Length of zipline = [tex]\sqrt{(60 - 0)^2 + (3 - 42)^2} = 3 \cdot \sqrt{569}[/tex] ≈ 71.56

Length of the zipline ≈ 71.56 ft.

Answer:

2x - y = - 8

Step-by-step explanation:

y - 4 = 2(x + 2) ← distribute

y - 4 = 2x + 4 ( subtract y from both sides )

- 4 = 2x - y + 4 ( subtract 4 from both sides )

- 8 = 2x - y , that is

Calculate the size of angle x.
angle x =

Answers

The size of angle x from the figure is 16 degrees

The sum of the interior angle of a triangle is 180 degrees, hence to get the value of X, we will take the sum of all the given angles and equate them to 180 degrees.

127 + 37 + X = 180

164 + x = 180

Subtract 164 from  both sides

164 + x - 164 = 180 - 164

x =16 degrees

Hence the size of angle x from the figure is 16 degrees

Learn more on angles here: https://brainly.com/question/16281260

Answer:

Solution :

As we know that the sum of interior angles of triangle is 180⁰.

Accounting to the question :

[tex]\implies[/tex] Sum of angles = 180⁰

[tex]\implies[/tex] 127⁰ + 37⁰ + X = 180⁰

[tex]\implies[/tex] 164⁰ + X = 180⁰

[tex]\implies[/tex] X = 180⁰ - 164⁰

[tex]\implies[/tex] X = 16⁰

Hence, the size of angle is 16.

1) 3x + y = 3

          y = -3x + 3

When x = 0  ;   y = 0  +3 = 3                          (0 , 3)

When x = 1   ;    y = -3*1 + 3 = -3 + 3 = 0        (1 , 0)

When  x = 2   ;   y = -3*2 + 3 = -6 +3 = -3      (2 , -3)

Plot the points (0 ,3 ) ; (1 ,0) and (2 , -3) in the graph and join them

2) y = x + 3

When x = 0  ; y = 0 +3 = 3           (0 , 3)

When x = 1   ; y = 1 + 3 = 4          (1 , 4)

When x = -3  ; y = - 3 + 3 = 0      (-3 , 0)

Plot the points (0,3) , (1, 4) and (-3 , 0) in the graph and join them

3) Plug in (4 , y) int he equation

y = x + 5

y = 4 + 5

y = 9

y = 9

5) 2x + y = 3

At x-intercept y = 0

2x + 0 = 3

2x = 3

x = 3/2

Formen equipos de tres integrantes y realicen un proyecto en el que expresen mediante una ecuación lineal el tiempo que demoraran en reunir 10000 pesos para fundar la Sociedad Cultural Digital, si saben que los meses que tienen 31 dias sus padres donan un tercio de la cantidad total para el ahorro, mientras que en los de 30 dias logran ahorrar dos tercios de la cantidad final. En cuantos meses podrán reunir la cantidad deseada​

Answers

Los estudiantes recaudarán un total de $ 10000 pesos en un mes de 31 días y un mes de 30 días.

En este caso, debemos construir una ecuación lineal en forma implícita, es decir, una ecuación de la forma:

[tex]a\cdot x + b\cdot y = c[/tex] (1)

Donde:

[tex]a, b[/tex] - Coeficientes de proporción de ahorro.[tex]c[/tex] - Coeficiente de proporción total del ahorro.[tex]x[/tex] - Cantidad de meses de 31 días.[tex]y[/tex] - Cantidad de meses de 30 días.

Si sabemos que la solución consiste únicamente en números naturales y si [tex]a = \frac{1}{3}[/tex], [tex]b = \frac{2}{3}[/tex] y [tex]c = 1[/tex], entonces tenemos la única solución disponible:

[tex]\frac{1}{3}\cdot x + \frac{2}{3}\cdot y = 1[/tex]

[tex]x + 2\cdot y = 3[/tex]

[tex]2\cdot y = 3 - x[/tex]

[tex]y = \frac{3}{2}-\frac{1}{2}\cdot x[/tex]

[tex](x, y) = (1, 1)[/tex]

Los estudiantes recaudarán un total de $ 10000 pesos en un mes de 31 días y un mes de 30 días.

This equation shows that the line is straight (also shown in the picture) and therefore must make it a linear graph.

For the graph to be non linear, the graph would be curved but this would mean the equation would have to be a quadratic - which it isn't.
