Answer:

a You must choose at least 3 marbles

Step-by-step explanation:

If the probability is equally likely that you will choose a red or blue marble (1/2)

Then the marbles will need to be the same size or you will know which the color of the marble by the size.

There needs to be the same number of marbles, or you will be more likely to pick the color with more marbles of that color

If you look, you will pick the color of the marble you want.

The probability is determined by the number of marbles in the bag, not by the number you choose

Musical megabytes How much disk space

alexdok [17]

Given:

Consider the file sizes (in megabytes) for 18 randomly selected files on Gabriel's mp3 player are shown in the below figure.

To find:

The outliers in the distribution.

Solution:

We have, the given data set

2.4, 2.7, 1.6 , 1.3 , 6.2, 1.3, 5.6, 1.1, 2.2, 1.9, 2.1, 4.4, 4.7, 3.0, 1.9, 2.5, 7.5, 5.0

Arrange the data in ascending order.

1.1, 1.3, 1.3, 1.6, 1.9, 1.9, 2.1, 2.2, 2.4, 2.5, 2.7, 3.0, 4.4, 4.7, 5.0, 5.6, 6.2, 7.5,

Divide the data in 4 equal parts.

(1.1, 1.3, 1.3, 1.6), 1.9, (1.9, 2.1, 2.2, 2.4),( 2.5, 2.7, 3.0, 4.4), 4.7, (5.0,5.6, 6.2, 7.5)

It is clear that,

$Q_1=1.9$

$Q_3=4.7$

$IQR=Q_3-Q_1$

$IQR=4.7-1.9$

$IQR=2.8$

Now,

$Interval=[Q_1-1.5IQR,Q_3+1.5IQR]$

$Interval=[1.9-1.5(2.8),4.7+1.5(2.8)]$

$Interval=[-2.3,8.9]$

All the data values lies in the interval [-2.3,8.9]. Therefore, the given data set have no outliers.

Match the y-coordinates with their corresponding pairs of x-coordinates on the unit circle. the x coordinates to choose from are

vaieri [72.5K]

Of the four x-coordinates to choose only 1/√(11) belongs can belong to the unit circle.

The other three x-coordinates are greater than 1, then they are out of the unit circle.

The unit circle formula is x^2 +y^2 = 1

Then to find the y-coordinate given the x-coordinate you can solve for y from that formula:

y^2 = 1 - x^2

y = (+/-)√(1-x^2)

Substitute the value of x

y = (+/-)√{1 - [1/√(11)]^2} = (+/-) √{(1 - 1/11} =(+/-) √ {(11 -1)/11 =(+/-)√(10/11) ≈ +/- 0.95

How can I find x? Click for picture.

romanna [79]

Answer: You add up all the terms given of EACH angle, and make this an addition problem that is "equal to 180" ; since all triangles have three angles that add up to 180 degrees. Then you solve for "x".
__________________________________________________
(as follows) ; to get: " x = 29 ⅔ ° " .
_______________________________________

3x + 4 + 2x + x + 8 = 180 ;
_______________________________________
Combine the "like terms" ;

3x + 2x + x = 6x ;

4 + 8 = 12

So, we have: 6x + 12 = 180 ;

Now, subtract "12" from each side of the equation:
__________________________________________
6x + 12 − 12 = 180 <span>− 12 ;
</span>__________________________________________
to get:

6x = 178 ;

Now, divide EACH SIDE of the equation by "6" ; to isolate "x" on one side of the equation; and to solve for "x" ;
______________________________________
6x / 6 = 178 / 6 ;

to get: x = 178/6 = 29 ⅔ ° .
______________________________________
x = 29 ⅔ ° .
