Answer:

x=2 (work is correct)
x=4
x=44
x=4
x=any number
impossible; no such number

Step-by-step explanation:

1. The equation is ...

3x +5 = 11

3x = 11 -5 = 6

x = 6/3 = 2 . . . . matches the work shown

2. The equation is ...

(x +2)·5 = 30

x +2 = 30/5 = 6

x = 6 -2 = 4

3. The equation is ...

(x/2) +2 = 24 . . . . matches the work shown

x/2 = 24 -2 = 22

x = 22·2 = 44

4. The equation is ...

2x +8 = x +12

2x = x + 12 -8 = x +4

2x -x = x -x +4

x = 4

5. The equation is ...

2x +4 -x -3 = x +1

x +1 = x +1 . . . . . true for any value of x

6. The equation is ...

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

x +6 = x +3 . . . . . not true for any number

<em>Additional comment</em>

The work shown is correct. You find x by writing and solving an appropriate equation. To solve the equation, undo the steps that are done to x. Undo addition by adding the opposite. Undo multiplication by diving by the multiplier. It often helps to collect terms before you start the "undo" steps.

For x on both sides of the equation (as in problems 4–6), you can subtract the term with the lowest coefficient. (Of course, you must subtract it from both sides of the equation.) In problem 5, if you do that, you get 1=1, which is true for any value of x. In problem 6, if you do that, you get 6=3, a false equation, indicating no value of x will make it true.

Hello,

So Y variable is what you would start with.

20 <= he'll start off with for a

40 <= what he'll start off with for b

And X variables would be the # of hours you're working.

10 <= meaning every hour worked is worth 10 dollars

5 <= meaning every hour worked will be paid 5 dollars

So let's just say for option a he works two hours

(Option A)

10 (2) + 20

20 + 20

= 40

(Option B)

5 (2) + 40

10 + 40

As for your equations

Y = 10x + 40

Y= 5x + 40

Answer:I don't know the exact problem but I'll just give you the formulas on how to find volume, circumference radious, and yada

Step-by-step explanation: to find volume.. you need to multiply pi times the radius to the power of 2.. to find the radius you need to divide the height and pi by the volume.. to find the cylinder circumference you need to multiply the radius by 2 the multiply the radius by pi which is 3.14

A consumer survey indicates that the average household spendsμ= $185on groceries each week. The distribution of spending amounts

Vitek1552 [10]

Answer:

$P(X>200)=P(\frac{X-\mu}{\sigma}>\frac{200-\mu}{\sigma})=P(Z>\frac{200-185}{25})=P(Z>0.6)$

And we can find this probability using the complement rule and with the normal standard table or excel:

$P(Z>0.6)=1-P(z$

Step-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".

Solution to the problem

Let X the random variable that represent the average household spent of a population, and for this case we know the distribution for X is given by:

$X \sim N(185,25)$

Where $\mu=185$ and $\sigma=25$

We are interested on this probability

$P(X>200)$

And the best way to solve this problem is using the normal standard distribution and the z score given by:

$z=\frac{x-\mu}{\sigma}$

If we apply this formula to our probability we got this:

$P(X>200)=P(\frac{X-\mu}{\sigma}>\frac{200-\mu}{\sigma})=P(Z>\frac{200-185}{25})=P(Z>0.6)$

And we can find this probability using the complement rule and with the normal standard table or excel:

$P(Z>0.6)=1-P(z$

The following table shows how the average constituency changes for two regional governing boards, joshua and salinas, when a new

The relative unfairness of an apportionment that gives a new board member to joshua rather than to salinas will be

<h3>How to calculate the values?</h3>

The relative unfairness of an apportionment that gives a new board member to joshua rather than to salinas will be:

= (1520 - 1232)/1232

= 288/1232

= 0.234

The relative unfairness of an apportionment that gives a new board member to salinas rather than to Joshua will be:

= (1448 - 1333)/1333

= 115/1333

= 0.086

The regional governing board that should receive the new board member is Salinas.
