Answer:

13%

Step-by-step explanation:

C(n, x) • p^{x} • q^{n-x}

x = number of successes = 2

p = probability of success = 3/7

q = probability of failure = 1 = 3/7

n = number of games

(3/7)^2 x (4/7)^(9-2) = 13%

The probability that an event will not happen is Upper P (Upper E prime) = 0.94. Find the probability that the event will happen
xxMikexx [17]

Answer: P(Upper E' prime) = 0.06

Step-by-step explanation:

Not happen:P(Upper E prime) = 0.94

Happen: P(Upper E' prime) = ?

P(Upper E' prime) + P(Upper E' prime) = 1

Therefore

P(Upper E' prime) + 0.94= 1

P(Upper E' prime) =1- 0.94

P(Upper E' prime) = 0.06

Calcula el radio de un cilindro que tiene 8 cm de altura y un volumen de 122 cm cúbicos
kondaur [170]

Answer:

\huge{ \boxed{ \sf{2.20 \: cm}}}

Step-by-step explanation:

\star{ \sf{ \:  altura  \: de \:  un \:  cilindro\:  =  \: 8 \: cm}}

\star{ \sf{ \: volumen  \: de  \: un  \: cilindro = 122  \: cm \:  cúbicos}} \:

\star {  \sf{ \: encontrar :radio   \: de  \: un  \:  cilindro }}

\boxed{ \sf{ \: Volume \: of \: a \: cylinder \:  =  \:  {\pi \: radius}^{2}  \: height}}

\mapsto{ \sf{122 \:  =  \: ( \frac{22}{7} )r \: ^{2}  \:  \times  \: 8}}

\mapsto{ \sf{122 = 25.14 \:  {r}^{2} }}

\mapsto{ \sf{25.14 \:  {r}^{2} = 122 }}

\mapsto{ \sf{ \frac{25.14 \:  {r}^{2} }{25.14}  =  \frac{122}{25.14}}}

\mapsto{ \sf{ {r}^{2} = 4.85 \: cm}}

\mapsto{ \sf{r = 2.20 \: cm}}

radio de un cilindro = 2.20 cm
