Answer:

$\large\boxed{x=\dfrac{23}{33}}$

Step-by-step explanation:

$\text{Let}\ x=0.\overline{69}\\\\x=0.696969...\qquad\text{multiply both sides by 100}\\\\100x=69.696969...\qquad\text{subtract}\ x\ \text{from}\ 100x:\\\\100x-x=69.696969...-0.696969...\\\\99x=69\qquad\text{divide both sides by 99}\\\\x=\dfrac{69}{99}\\\\x=\dfrac{23}{33}$

A pitcher struck out 11 out of 40 batters. Write an equivalent decimal.

Komok [63]

Answer:

0.275

Step-by-step explanation:

We want to write 11 out of 40 batters as a decimal.

We can write 11 out of 40 as a fraction to get:

$\frac{11}{40}$

Note that:

$\frac{11}{40} = \frac{1}{4} \times \frac{11}{10}$

This implies that:

$\frac{11}{40} = 0.25 \times 1.1$

This gives us

$\frac{11}{40 } = 0.275$

g Two teams compete in the NBA (National Basketball Associa- tion) championshipseries. The team who wins four games out of seven

Firlakuza [10]

Answer: The required probability is 0.32.

Step-by-step explanation:

Since we have given that

Probability of winning team A over B = 0.7

Probability of losing team A over B = 0.3

Number of matches = 7"

So, using the "Binomial distribution" :

We get that

$P(X=5)=^7C_5(0.7)^5(0.3)^2=0.32$

Hence, the required probability is 0.32.
