Find the value of x. If necessary, round your answer to the nearest tenth. O is the center of the circle. The figure is not draw

g100num [7]

Answer:

The correct answer is first option 15

Step-by-step explanation:

From the figure we can see a circle with center O.

<u>To find the value of x</u>

Here 'x' is the radius of the given circle.

Using the given information we can write,

x² = 12² + 9²

= 144 + 81

= 225

x = √225

x = 15

Therefore the correct answer is first option 15

The dot plot shows the number of books lent by a school library during a 10-day period.

Katyanochek1 [597]

The mean absolute deviation of the number of books is 1.84

<h3>How to determine the mean absolute deviation?</h3>

The dot plot of the number of books is in the attached figure.

From the figure, we have:

x f

1 1

2 2

3 2

4 3

5 1

6 2

7 3

8 1

Start by calculating the mean using:

$\bar x= \frac{\sum fx}{\sum f}$

So, we have:

$\bar x= \frac{1 * 1 + 2 * 2 + 2 * 3 + 3 * 4 + 1 * 5 + 2 * 6 + 3 *7 + 1 * 8}{1 +2+2+3+1+2+3+1}$

Evaluate the sum and products

$\bar x= \frac{69}{15}$

Divide

$\bar x= 4.6$

The mean absolute deviation is then calculated as:

$|\bar x| = \frac{\sum f|x - \bar x|}{\sum f}$

So, we have:

$|\bar x|= \frac{1 * |1 -4.6|+ 2 * |2 -4.6| + 2 * |3 -4.6|+ 3 * |4 -4.6|+ 1 *| 5 -4.6|+ 2 * |6 -4.6|+ 3 *|7 -4.6|+ 1 * |8-4.6|}{1 +2+2+3+1+2+3+1}$

Evaluate the absolute difference

$|\bar x|= \frac{1 * 3.6+ 2 * 2.6 + 2 * 1.6+ 3 * 0.6+ 1 *0.4+ 2 * 1.4+ 3 *2.4+ 1 * 3.4}{15}$

Evaluate the sum of products

$|\bar x|= \frac{27.6}{15}$

Divide

$|\bar x|= 1.84$

Hence, the mean absolute deviation of the number of books is 1.84

8 9/10 into an improper fraction in lowest terms

jarptica [38.1K]

Improper fractions have a greater numerator than the denominator:

8 = 8*(10/10) = 80/10

now add

8 + 9/10

80/10 + 9/10

(80 + 9)/10

89/10

find the value of c that makes each trinomial a perfect square. then write the trinomial as a perfect square. the equation , x^2

mr Goodwill [35]

Therefore, the value of C should be (11/2)^2

<span>To square a fraction, take the square of the numerator and put it over the square of the denominator. So since 11^2=121 and 2^2=4, (11/2)^2
(11)^2/(2)^2=121/4
</span>
