11, 12, 15, 16, 20, 20, 25
Mean: 17

The range is 25-11 = 14 (the numbers in bold)

The interquartile range is 20-12=8 (the numbers underlined)

The mean absolute deviation is: 4; this is found by finding how far each number is from 17 (mean): 6,5,2,1,3,3,8  (28) and dividing by 7.

Part B:

The prices vary by no more that $14 (range).

<span>The middle half of the prices vary by no more than $8 (IQR).
</span>
<span>The admission prices differ from the mean price by an average of $4 (MAD).</span>

9x-7=-7<br><img src="https://tex.z-dn.net/?f=9x%20-%207%20%3D%20-%207" id="TexFormula1" title="9x - 7 = - 7" alt="9x - 7 = - 7"
scZoUnD [109]

Answer:

x= 0

Step-by-step explanation:

Here in this question, we are given a linear equation of single variable x, and we have to solve the equation for x.

The given equation is 9x -7= -7 ....... (1)

Now, taking all the constant terms to the right side of the equation and all the x terms to the left side of the equation.

Hence, the equation becomes  

9x = -7 +7

⇒ 9x =0 {Since, -7 and 7 cancels each other}

⇒ x= 0/9= 0 (Answer) {Since zero divided by any number is equal to zero}

What is the solution to this equation 1^6 x =2
Alenkinab [10]
<h2>Greetings!</h2>

Anything to the power of 1 is still 1, because 1^{6} is simply 1 x 1 x 1 x 1 x 1 = 1 ect.

<h3>So this changes the equation to 1x = 2, which means that:</h3>

x = 2

<h2>Hope this helps!</h2>

Answer by macston (5194) About Me  (Show Source):

You can put this solution on YOUR website!

If 37% get less than 8 hours of sleep, 100%-37%=63%

63% get 8 hours or more per night:

(0.63)(2200)=1386

ANSWER: You would expect 1386 to get 8 or more hours of sleep per night.

   This is an equation! Solutions: x=1.

   Graphical form: Equation 3%2Ax-x%2B2=4 was fully solved.

   Text form: 3*x-x+2=4 simplifies to 0=0

   Cartoon (animation) form: simplify_cartoon%28+3%2Ax-x%2B2=4+%29

   For tutors: simplify_cartoon( 3*x-x+2=4 )

Alinara [238K]

Answer:

log_{10}(x )  = 4

the property of Logarithms,

log_a(x)= y \\ \implies x=a^y

so,

x =  {10}^{4}
