Contact [7]

<h2>Answer:</h2><h2>The correct option to the given question is J</h2>

Step-by-step explanation:

Real numbers are classified into two types,

(i) Rational numbers - A number which can be expressed as fraction, ratio or percentage is called as rational number

(ii)Irrational numbers - A number which is not rational, (i.e) cannot be expressed as a ratio or percentage is called as irrational number.

Since there are no common numbers in rational and irrational, they cannot be expressed as "G" option.

Real numbers are formed by the union of rational and irrational numbers.

4. In a sample of 1000 people, 130 can wiggle their ears. Two unrelated people are

Elina [12.6K]

Using the hypergeometric distribution, it is found that there is a 0.7568 = 75.68% probability that neither can wiggle his or her ears.

The people are chosen from the sample without replacement, which is why the <u>hypergeometric distribution</u> is used to solve this question.

Hypergeometric distribution:

$P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}$

$C_{n,x} = \frac{n!}{x!(n-x)!}$

The parameters are:

x is the number of successes.
N is the size of the population.
n is the size of the sample.
k is the total number of desired outcomes.

In this problem:

1000 people means that $N = 1000$
130 can wiggle their ears, thus $k = 130$
Two are selected, thus $n = 2$ .

The probability that neither can wiggle his or her ears is P(X = 0), thus:

$P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}$

$P(X = x) = h(0,1000,2,130) = \frac{C_{130,0}C_{870,2}}{C_{1000,2}} = 0.7568$

0.7568 = 75.68% probability that neither can wiggle his or her ears.

2p-b=c-ap<br><br> solve for tems of p <br> so p=bla bla bla

vitfil [10]

2p-b=c-ap

2p+ap=c+b

p(2+a)=c+b

So, p=(c+b)/(2+a)

True or false and why: if a and b are irrational, then a^b is irrational

FrozenT [24]

False

b could be the logarithm of a rational number to the base a. For example,

$b=\log_\pi{(4)}$ will be irrational, but π^b = 4, a rational number
