Step-by-step explanation:

The polygon will be a triangle if the measure of each exterior angle is twice as large as each interior angle.

A polygon is a geometric figure with a finite number of sides in two dimensions. On the sides or edges of a polygon, straight-line segments are joined end to end to form a closed shape. The vertices, also known as corners, are the points where two line segments meet and form an angle.

As we know, the interior angle is given by:

= 180(n - 2)

Sum of the exterior angle is 360 degree

(360/n) = 2[180(n - 2)]/n

360 = 360(n - 2)

n = 3

Number of sides n = 3

Polygon will be a triangle

Thus, the polygon will be a triangle if the measure of each exterior angle is twice as large as each interior angle.

Answer:

The slope of line g is [tex]\frac{2}{9}[/tex].  

Step-by-step explanation:

We know that line f has a slope of [tex]-\frac{9}{2}[/tex] and that line g and line f are perpendicular to each other. Perpendicular lines have slopes that are opposite reciprocals of each other. Thus, the opposite reciprocal of  [tex]-\frac{9}{2}[/tex] must be the slope of line g.  

To find the opposite reciprocal of a number, change its sign and swap the numbers of the numerator and the denominator. So, the opposite reciprocal of [tex]-\frac{9}{2}[/tex] must be [tex]\frac{2}{9}[/tex]. [tex]\frac{2}{9}[/tex] has to be the slope of line g as well.

Responder:

0,1536

0.0256

0.4096

Explicación paso a paso:

Dado que :

p = 0,2

Número de ensayos, n = 4

1 - p = 1 - 0,2 = 0,8

Probabilidad de que 2 sean defectuosos;

Usando la fórmula de distribución binomial:

P (x = 2)

P (x = x) = nCx * p ^ x * (1 - p) ^ (n - x)

P (x = 2) = 4C2 * 0.2 ^ 2 * 0.8 ^ 2

P (x = 2) = 6 * 0,04 * 0,64

P (x = 2) = 0,1536

3 están defectuosos:

P (x = 3) = 4C3 * 0,2 ^ 3 * 0,8 ^ 1

P (x = 3) = 4 * 0,008 * 0,8

P (x = 3) = 0,0256

Probabilidad de que ninguno sea defectuoso:

P (x = 0) = 4C0 * 0.2 ^ 0 * 0.8 ^ 4

P (x = 0) = 1 * 1 * 0,4096

P (x = 0) = 0,4096

Usando la distribución binomial, se encuentra que hay una probabilidad de:

a) 0.1536 = 15.35% que 2 sean defectuosos.

b) 0.0256 = 2.56% que 3 sean defectuosos.

c) 0.4096 = 40.96% que ninguno sea defectuosos.

Para cada objeto, solo hay dos resultados posibles. O está defectuoso o no lo es. La probabilidad de que un objeto sea defectuoso es independiente de cualquier otro ítem, lo que significa que se utiliza la distribución binomial para resolver esta cuestión.

Distribución binomial:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

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

Los parámetros son:

En este problema:

Item a:

Esta probabilidad es P(X = 2), o sea:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 2) = C_{4,2}.(0.2)^{2}.(0.8)^{2} = 0.1536[/tex]

Probabilidad de 0.1536 = 15.35% que 2 sean defectuosos.

Item b:

Esta probabilidad es P(X = 3), o sea:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 3) = C_{4,3}.(0.2)^{3}.(0.8)^{1} = 0.0256[/tex]

Probabilidad de 0.0256 = 2.56% que 3 sean defectuosos.

Item c:

Esta probabilidad es P(X = 0), o sea:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 0) = C_{4,0}.(0.2)^{0}.(0.8)^{4} = 0.4096[/tex]

Probabilidad de 0.4096 = 40.96% que ninguno sea defectuosos.

Answer: The time taken for the mass to reduce from 50 g to 41 g is 6 years

Step-by-step explanation:

Expression for rate law for first order kinetics is given by

[tex]t=\frac{2.303}{k}\log\frac{a}{a-x}[/tex]

where,

k = rate constant  

t = age of sample

a = let initial amount of the reactant  

a - x = amount left after decay process  

a) for completion of half life:

Half life is the amount of time taken by a radioactive material to decay to half of its original value.

[tex]t_{\frac{1}{2}}=22 years[/tex]

[tex]k=\frac{0.693}{t_{\frac{1}{2}}}=\frac{0.693}{22}=0.0315years^{-1}[/tex]  

b) for mass to reduce from 50 g to 41 g

[tex]t=\frac{2.303}{0.0315}\log\frac{50}{41}[/tex]

[tex]t=6years[/tex]  

The time taken for the mass to reduce from 50 g to 41 g is 6 years
