Answer:

sample proportion = 0.65

The percentage of the sample proportion

= 65%

The percentage of the readers surveyed do not use e-readers = 35%

Step-by-step explanation:

<em>Given sample size 'n' =3000</em>

<em>Of the 3,000 readers surveyed, 1,954 said they read books on an e-reader.</em>

<em>The probability that The readers surveyed use e-readers</em>

<em>sample proportion </em>

$p = \frac{x}{n} = \frac{1954}{3000} = 0.6513$

The percentage of the sample proportion

= 65%

<em><u>Step(ii):</u></em>-

The readers surveyed do not use e-readers

= $q= 1-p = 1-0.651 = 0.349$

The percentage of the readers surveyed do not use e-readers = 35%

<h3>hello!</h3>

$========================================$

is the product of an irrational number and an irrational number always irrational?

We can easily check that by just multiplying some irrational numbers on our calculator.

Let's take

$\pmb{\sqrt{2} }$ times $\pmb{\sqrt{5} }$

Multiply:-

The result is an irrational number.

Let's try to multiply π times itself.

Once again, we have an $\pmb{irrational}$ number.

Hence, the answer is:-

$\pmb{Always~True}$

Terrence has 64 stamps. Of his stamps, 12 are from Europe and 1/4 are from Africa. The rest are from Asia. What fraction of his

Tamiku [17]

16 of his stamps are from Africa, since 1/4 of 64 is 16. If I subtract his 28 from Europe and Africa (16 plus 12 equals 28) from his original 64, I am left with 36 stamps. 36/64 is simplified to 9/16. So 9/16 of Terrence's stamps are from Asia.
