There are 5.2 x 10^5 words in the English dictionary. What is the average number of words recorded under each of the 26 letters?

alexira [117]

Answer:

2.0*10^4

Step-by-step explanation:

$5.2 *10^5$ words

26 categories

$\frac{5.2 *10^5}{26} =\frac{520 000}{26} =20 000$

$2.0*10^4$

so there is an average of 2.0*10^4 words per letter

What is the greatest common factor of 9 and 27

agasfer [191]

<u><em>9 is the greatest common factor correct answer.</em></u> First you had to find prime factorization of 9: 1, 3, 9, 3²=3*3=9. And then, you had to find prime factorization of 27: 1, 3, 9, 27, 3³=3*3*3=27. The greatest common factor of 9 and 27 is 9 is the final answer. Hope this helps! And thank you for posting your question at here on brainly, and have a great day. -Charlie

ASHA 777 [7]

Answer:

Step-by-step explanation:

Let x represent the amount that he paid for one hamburger.

Daniel buys lunch for his family from a food stand. He purchased one hot dog for $2.50 and 3 hamburgers. The cost of 3 hamburgers would be 3x.

If he spent a total amount of $13 on the hot dog and hamburgers, it means that

2.5 + 3x = 13

3x = 13 - 2.5 = 10.5

x = 10.5/3

x = $3.5

Maria divides 2015 by 1. Then she divides 2015 by 2 and then in order by 3, 4 etc. up to and including 1000. For each division s

9966 [12]

The biggest remainder obtained by dividing 2015 by either 1, 2, 3,

4,...,1000 is the option;

<h3>How can the biggest remainder be found?</h3>

The given number Maria divides is 2015

The divisors = 1, 2, 3, 4,..., 1000

Required:

The biggest remainder Maria noted down.

Solution:

From remainder theorem, we have;

p(x) = (x - a) × q·(x) + r(x)

Where;

r(x) = The remainder

q(x) = The quotient

(x - a) = The devisor

Which gives;

$\dfrac{r(x) }{(x - a)} = \dfrac{p(x) }{(x - a)} -\dfrac{(x - a) \times q(x) }{(x - a)} = \mathbf{ \dfrac{p(x) }{(x - a)} -q(x)}$

Therefore;

$r(x) = \mathbf{\left(\dfrac{p(x) }{(x - a)} -q(x) \right) \times (x - a)}$

The remainder is largest when both $\left(\dfrac{p(x) }{(x - a)} -q(x) \right)$ and (x - a) are large

$\left(\dfrac{p(x) }{(x - a)} -q(x) \right)$ is largest when the quotient changes to the next lower

digit and the divisor is not a factor.

By using MS Excel, we have, at 672, the remainder is found as follows;

$r(x) = \left(\dfrac{2015}{672} -2\right) \times (672) = 671$

At 672, $\left(\dfrac{p(x) }{(x - a)} -q(x) \right)$ ≈ 0.999, which when multiplied by 672, gives

the biggest remainder of 671, which is the biggest remainder.

The biggest remainder obtained by dividing 2015 by either 1, 2, 3, 4,...,1000 is <u>(C) 671</u>
