Answer:

Step-by-step explanation:

<em>START:</em> 4x + 10 = - 26 ⇔ 4x = - 36 ⇔ <em>x = - 9</em>

\frac{1}{2} x + 13 = 9 ⇔\frac{1}{2} x = - 4 ⇔ <em>x = 8</em>

\frac{3}{4} x - 9 = 27 ⇔ \frac{3}{4} x = 36 ⇔ <em>x = 48</em>

9 - 2x = 35 2x = - 35 + 9 ⇔ <em>x = - 13</em>

\frac{2}{3} x + 15 = 17 ⇔ \frac{2}{3} x = 2 ⇔ <em>x = 3</em>

- 5x - 10 = 10 ⇔ 5x = - 20 ⇔ <em>x = - 4</em>

Now is your turn. You can do it!!!

Answer:

Look in the picture;^_^

Start;

4x + 10 =  - 26 \\ 4x =  - 26 - 10 \\ 4x =  - 36 \\  \\ x =  \frac{ - 36}{4}  \\  \\ x =  - 9

To —> – 9

\frac{1}{2} x + 13 = 9 \\  \\  \frac{1}{2} x = 9 - 13 \\  \\  \frac{1}{2} x =  - 4 \\  \\ x =  - 4 \div  \frac{1}{2}  \\  \\ x =  - 4 \times 2 \\ x =  - 8

To —> – 8

\frac{x}{3}  + 10 = 15 \\  \\  \frac{x}{3} = 15 - 10 \\  \\  \frac{x}{3}   = 5 \\  \\ x = 5 \times 3 \\ x = 15

To —> 15

9 - 2x = 35 \\ 2x = 9 - 35 \\ 2x =  - 26 \\ x =  \frac{ - 26}{2}  \\  \\ x =  - 13

To —> – 13

\frac{2}{3} x + 15 = 17 \\  \\  \frac{2}{3} x = 17 - 15 \\  \frac{2}{3} x = 2 \\ x = 2 \div  \frac{2}{3}  \\ \\  x = 2  \times  \frac{3}{2}  \\  \\ x = 3

To —> 3

- 5x - 10 = 10 \\ 5x =  - 10 - 10 \\ 5x =  - 20 \\  \\ x =  \frac{ - 20}{5}  \\  \\ x =  - 4

To —> – 4

- 8 =  \frac{x + 11}{ - 2}  \\  \\ x + 11 =  - 2 \times  - 8 \\ x + 11 = 16 \\ x = 16 - 11 \\ x = 5

To —> 5

- 12x - 17 =  - 89 \\  12x =89 - 17 \\ 12x = 72 \\ x =  \frac{72}{12}  \\ \\  x = 6

To —> 6

8 -  \frac{1}{3} x = 16 \\  \frac{1}{3} x = 8 - 16 \\  \frac{1}{3} x =  - 8 \\ x =  - 8 \div  \frac{1}{3}  \\ \\  x =  - 8 \times 3 \\ x =  - 24

To —> – 24

5 - x = 12 \\ x = 5 - 12 \\ x =  - 7

To —> – 7

13 -  \frac{3}{2} x = 37 \\  \\  \frac{3}{2}x = 13 - 37 \\  \\  \frac{3}{2}  x =  - 24 \\  \\ x =  - 24 \div  \frac{3}{2}  \\  \\ x =  - 24 \times  \frac{2}{3}  \\  \\ x =  - 16

To —> – 16

We are interested in conducting a study to determine the percentage of voters of a state would vote for the incumbent governor.
Vladimir [108]

Answer:

n=\frac{0.5(1-0.5)}{(\frac{0.05}{1.96})^2}=384.16  

And rounded up we have that n=385

Step-by-step explanation:

In order to find the critical value we need to take in count that we are finding the interval for a proportion, so on this case we need to use the z distribution. Since our interval is at 95% of confidence, our significance level would be given by \alpha=1-0.95=0.05 and \alpha/2 =0.025. And the critical value would be given by:

z_{\alpha/2}=-1.96, z_{1-\alpha/2}=1.96

The margin of error for the proportion interval is given by this formula:  

ME=z_{\alpha/2}\sqrt{\frac{\hat p (1-\hat p)}{n}}    (a)  

And on this case we have that ME =\pm 0.05 and we are interested in order to find the value of n, if we solve n from equation (a) we got:  

n=\frac{\hat p (1-\hat p)}{(\frac{ME}{z})^2}   (b)  

The estimated proportion for this case is \hat p=0.5. And replacing into equation (b) the values from part a we got:

n=\frac{0.5(1-0.5)}{(\frac{0.05}{1.96})^2}=384.16  

And rounded up we have that n=385
