The answer of 9-6=A(or any other letter) A=3.so for an addition problem just do A+6=9 or 6+A=9 .You do this because you are just doing the inverse operation.

For this case, the first thing we must do is define a variable:
 x: unknown number
 We then have the following equation:
 9-6 = x

 We are going to rewrite the equation as an addition equation.
 To do this, we add 6 on both sides of the equation:
 9-6 + 6 = x + 6

 Let's rewrite the left side of the equation:
 9 + 0 = x + 6

9 = x + 6
 Answer:
 
an addition equation that can help you find 9-6 is:
 
9 = x + 6

When the net is folded into the rectangular prism shown beside it, which letters will be on the front and back of the rectangula
earnstyle [38]
<h2>Answer:</h2>

<u>The correct option is </u><u>The letter on the front will be N. The letter on the back will be L. </u>

<h2>Step-by-step explanation:</h2>

When we fold the given net, we will get Q,P,M and N on sides. Side M will come to the top, side Q on the right side, side P on the left and side O on the bottom. The side which comes to the front will  be N of the observer and similarly the side L will come to the back of the rectangular prism.

Answer:

The  value is  P(A) =  0.133617

Step-by-step explanation:

From the question we are told that

  The  mean is  \mu =  7.5

  The standard deviation is  \sigma  =  0.2

  The safest water level is  between  7.2 and  7.8

Generally the probability that the selected pool has a pH level that is not considered safe is mathematically represented as

       P(A) =  1 - P(7.2 \le X  \le 7.8 )

Here  

      P(7.2 < X  < 7.8 ) = P(\frac{ 7.2 - \mu }{\sigma } <  \frac{X - \mu }{ \sigma }

Generally \frac{X - \mu }{ \sigma } =  Z (The  \ standardized \  value  \  of  X )

So

 P(7.2 < X  < 7.8 ) = P(\frac{ 7.2 - 7.5 }{0.2 } < Z    

 P(7.2 < X  < 7.8 ) = P(-1.5 < Z  

=>  P(7.2 < X  < 7.8 ) = P(Z <  1.5) - P(  Z < - 1.5)

From the z-table the probability of  (Z <  -1.5) and   (  Z <1.5)  are

    P(Z <  1.5) =  0.93319

and  

    P(Z <  -1.5) =  0.066807

So

      P(7.2 < X  < 7.8 ) =0.93319 - 0.066807

       P(7.2 < X  < 7.8 ) =0.0866383

So

   P(A) =  1 - 0.0866383

=>  P(A) =  0.133617

Identify The functional relationship between the variables blank is a function of blank
vfiekz [6]
<h2>Complete Question: </h2>

The energy usage of a light bulb is a function. The input for the function is ___, measured in hours. The output of the function is energy usage, measured in _____. Identify the functional relationship between the variables. ________ is a function of __________. The graph of the function will show energy usage on the ________ axis and time on the _______ axis.

  • Input is <u>time</u>.
  • Output is measured in <u>kilowatts</u>.
  • <u>Energy usage</u> measured in kilowatts is a function of <u>time</u> measured in hours.

The graph representing the function will show:

  • energy usage (kilowatts) on the <u>y-axis</u>
  • time (hours) on the <u>x-axis.</u>

A light bulb as a function expends energy which is measured in kilowatts and it is dependent on time measured in hours.

This implies that, the amount of energy usage of the light bulb is determined by the number of hours the light bulb is turned on.

Thus, energy usage of the light bulb (kilowatts) is a function of time (hours).

Graphing the function, we would plot<em><u> the input (time) on the x-axis, against (output) energy usage on the y-axis.</u></em>

<em>Therefore</em>,

Input = time (hours) - plotted on the x-axis.

Output = energy usage (kilowatts) - plotted on the y-axis.
