line f has a slope of -9/2. line g is perpendicular to f what is the slope of line g
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.

Step-by-step explanation:
The given relation is :
[tex]y=-0.11x+24.9[/tex] ...(1)
We need to describe this relationship in words.
The general equation of a line is given by :
y = mx +c ...(2)
comparing equations (1) and (2).
m = -0.11 and c = 24.9
It shows that the slope of the line is -0.11 and the y-intercept is 24.9.

Element X is a radioactive isotope such that every 22 years, its mass decreases by
half. Given that the initial mass of a sample of Element X is 50 grams, how long
would it be until the mass of the sample reached 41 grams, to the nearest tenth of a
year?
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

I NEED HELP
Answer:
i dont know im sorry
Step-by-step explanation:
Supongamos que el 20% de los objetos fabricados por una empresa son defectuosos. Escogemos 4 objetos al azar. Hallar la probabilidad de que (a) 2 sean defectuosos, (b) 3 sean defectuosos, (c) ninguno sea defectuoso.
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:
n es el número de ensayos. p es la probabilidad de éxito en un ensayo x es el número de éxitosEn este problema:
4 objetos, por eso [tex]n = 4[/tex].20% son defectuosos, por eso [tex]p = 0.2[/tex].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.
