Answer:

The answer is x = 1/11

Step-by-step explanation:

hope this helps

10x + 5x – 3 = 2(2x – 1)

10x+5x-3=4x-2

15x-4x=-2+3

11x=1

To find x divide both sides by 11

11x/11=1/11

x= 1/11

<h3><u><em>Answer:</em></u></h3>

$\frac{1}{11} or 0.0909090909090$

<h3><u><em>Step-by-step explanation:</em></u></h3>

Add similar elements: 15x-3=2(2x-1)

Expand 2(2x-1): 4x-2

Add 3 to both sides

Simplify 15x=4x+1

Subtract 4x from both sides

Simplify 11x=1

Divide both sides by 11

Simplify $\frac{1}{11} or 0.0909090909090$

How to calculate the mean

Romashka [77]

Hey there!

In order to calculate the mean you have to add up all up your given numbers (its the average number in total) then divide it by the total numbers you have

Example ⬇

Given: 3, 10, 45

Setting them up (Add) 3 + 10 + 45

Total numbers (Divide) : 3

➡ 3 + 10 + 45 = 58

➡ 58 / 3 = 19.3(repeated of 3)

Good luck on your assignment and enjoy your day!

What is the equation of the line perpendicular to 3x+4y=12 and containing the point (6,-2)

tester [92]

3x+4y=12

4y = - 3x + 12

y = -3/4 x + 3; This line has slope equal - 3/4

Perpendicular lines, slope is opposite and reciprocal so slope of new line = 4/3

Passing point (6 , -2)

y + 2 = 4/3(x - 6)

y + 2 = 4/3 x - 8

y = 4/3 x - 10

Answer

Equation: y = 4/3 x - 10

The following data give the annual salaries (in thousand dollars) of 20 randomly selected health care workers. 50 72 56 38 46 65

Afina-wow [57]

Answer:

So, the interquartile range is IQR=22.5.

Step-by-step explanation:

Let us write the numbers in ascending order:

34, 37, 38, 40, 44, | 46, 50, 51, 55, 56, |

57, 61, 62, 65, 65, | 68, 68, 72, 73, 76.

We calculate quartile 1:

$Q_1=\frac{44+46}{2}=45$

We calculate quartile 2:

$Q_2=\frac{56+57}{2}=56.5\\$

We calculate quartile 3:

$Q_3=\frac{65+68}{2}=67.5\\$

We calculate the interquartile range:

$IQR=Q_3-Q_1\\\\IQR=67.5-45\\\\IQR=22.5$
