2 5/7+4 3/5= help please
Ainat [17]

Answer:

7\frac{11}{35}

Step-by-step explanation:

2\frac{5}{7}+4\frac{3}{5}

add the whole numbers

2+4=6

combine the fractions

\frac{5}{7}+\frac{3}{5}

LCM is 35 because 7 * 5 =35

\frac{5}{7}=\frac{5\cdot \:5}{7\cdot \:5}=\frac{25}{35}

\frac{3}{5}=\frac{3\cdot \:7}{5\cdot \:7}=\frac{21}{35}

\frac{25}{35}+\frac{21}{35}=\frac{25+21}{35}

=\frac{46}{35}

change the improper fraction into mixed number

6+1\frac{11}{35}

=7\frac{11}{35}

Six percent of computer chips produced by Cheapo Chips are defective. Each month a random sample of 200 chips manufactured that
zzz [600]

Using the binomial distribution, it is found that the mean of X is of 12, with a standard deviation of 3.36.

For each chip, there are only two possible outcomes, either it is defective, or it is not. The probability of a chip being defective is independent of any other chip, hence, the binomial distribution is used to solve this question.

Binomial probability distribution

Probability of exactly <u>x successes on n repeated trials, with p probability.</u>  

The mean of the binomial distribution is:

E(X) = np

The standard deviation of the binomial distribution is:

\sqrt{V(X)} = \sqrt{np(1-p)}

In this problem:

  • Six percent of computer chips produced by Cheapo Chips are defective, hence p = 0.06.
  • Each month a random sample of 200 chips manufactured that month are taken, hence n = 200

Then:

E(X) = np = 200(0.06) = 12

\sqrt{V(X)} = \sqrt{np(1 - p)} = \sqrt{200(0.06)(0.94)} = 3.36

The mean of X is of 12, with a standard deviation of 3.36.
