289 196 248 379 319 276 198 349

(in order) 196, 198, 248, 276, 289, 319, 349, 379 there are eight numbers.

--------------------------------------------------------------------------------------

196, 198, 248, 276

since the median is between 198 and 248, we must add both numbers together and divide them by two:

(198 + 248) ÷ 2

= 446/2

<h2>= 223 (first quartile)</h2>

--------------------------------------------------------------------------------------

289, 319, 349, 379

since the median is between 319 and 349, we must add both numbers together and divide them by two:

(319 + 349) ÷ 2

= 668/2

<h2>= 334 (third quartile)</h2>

Gre4nikov [31]

Answer:

There are 700 books in Library Collections.

Step-by-step explanation:

Given:

Number of historical books = 70

The equation used to find the totals number of books in library collection.

$\frac{1}{10}b = 70$

where b⇒ Total number of books in library collections.

We need to find the Total number of books in library collections.

Solution:

$\frac{1}{10}b = 70$

Now by solving the above equation we get;

First we will multiply both side by 10 we get;

$\frac{1}{10}b \times 10= 70\times 10\\\\b =700$

Hence there are 700 books in Library Collections.

What times what equals 19

andreyandreev [35.5K]

19 is prime meaning that only 1 and itself can multiply to get that number (excluding decimals and fractions)
so the answer would be 1 times 19

or if you want to multiply by a fraction to divide you could do
38 times 1/2=19
