-19+3x-11+2x=2

-19-11+3x+2x= 2

-30+5x= 2

Move -30 to other side. Sign changes from -30 to +30 .

-30+30+5x= 2+30

5x= 32

Divide by 5

5x/5= 32/5

Cross out 5 and 5 , divide by 5. Becomes : x= 32/5

Answer:

1.   2

2.  6

3.  2

4.  3

5.  1

6.   1

Step-by-step explanation:

First put the data in order from smallest to largest

2,2,2,3,3,6

The minimum is 2

The maximum is 6

The median is 2,2,2    ,3,3,6  is between the 2 and 3  (2+3)/2 = 2.5

The 1st quartile is 2,2,2  is the middle number   = 2

The third quartile is   3,3,6  is the middle number is 3

The interquartile range is 3-2 =1

The mean average deviation is

First find the mean: ( 2+2+2+3+3+6)/6 =18/6 = 3

Then find how far each point is from the mean

(3-2) + (3-2) + (3-2) + (3-3) + (3-3) + (6-3)  = 6

Divide this by the number of data points

6/6 =1

What is the length of x?
Marat540 [252]

Answer:

The length of 'x' is 4

Step-by-step explanation:

We can use the pythagorean theorem to solve this.

The pythagorean theorem is:

a ^{2}  + b^{2}  =  {c}^{2}

a ^{2}  + b^{2} =  c^{2}  \\  {3}^{2}  +  {b}^{2}  = 5^{2}  \\ 9 +   {b}^{2}  = 25 \\  \frac{ - 9 \:  \:  \:  \:  \:  \:  \:  \:  =  - 9}{b ^{2}  =  \sqrt{16} }  \\ b = 4

Therefore x = 4
