how to find the circumference for a 3 inch circle using 3.14 for pi

Answer:

21 ft²

Step-by-step explanation:

3*5 + 2*3 = 21

J = (3,0)

K = (3,negative two)

L = [ 0, negative two]

I apologise for the way this is set out, half of the keys on my laptop do not work

Answer:

J- (3,0)

K- (3,-2)

L- (1,-2)

Reasoning- Just move the points to where it's asking.

Answer:

k = 20

Step-by-step explanation:

we have to add 16 and 4 to get 20. 20 - 16 = 4! hope this helps :)

Answer:

Add 16 on both sides,

k-16+16=4+16

k=20

Answer: Their are 40 cm salsa in the jar.

1500cm are missing in the jar.

Step-by-step explanation:

Because cm is 10 and if you multiply 10x15 you will get 1500. If you multiply 10 and 4 you will get 40.

Answer:

x = 8√2

Step-by-step explanation:

Use Pythagorean Theorem to solve for x.

x² + x² = 16²

⇒ 2x² = 256

⇒ x² = 128

⇒ x = 8√2

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:

9

Step-by-step explanation:

if you mean -3.2x+9 then the answer is 9 because you plug in 0 into x and solve the equation, you get the x intercept

Answer:

3 times a number is 3x

decreased by 14 is '- 14'

is 4 is '= 4'

So we have:

3x - 14 = 4

Add 14 to both sides:

3x = 18

Divide 3 to both sides:

x = 6

Step-by-step explanation:

The expression for the given statement "fourteen decreased by three times four" is written as 14 - (3×4), and its solution is 2.

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

The given statement "fourteen decreased by three times four" can be written in the form of expression as,

14 - (3×4)

Now, if we solve the expression, the solution will be,

14 - (3×4)

= 14 - 12

= 2

Hence, the expression for the given statement "fourteen decreased by three times four" is written as 14 - (3×4), and its solution is 2.

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]
