10x +7 = -3х – 3 help guys
Pepsi [2]

Answer:

x = -10/13

Step-by-step explanation:

10x + 7 = -3x - 3

Add 3x to both sides

10x + 3x + 7 = -3x + 3x - 3

13x + 7 = 0x - 3

13x + 7 = -3

Subtract 7 from both sides

13x + 7 - 7 = -3 - 7

13x + 0 = -10

13x = -10

Divide both sides by 13

13x ÷ 13 = -10 ÷ 13

1x = -10/13

x = -10/13

Murljashka [212]

Answer:

For the first question the sample size is n= 3850

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

\hat p \pm ME

And replacing we got:

0.5- 0.016 = 0.484

0.5+ 0.016 = 0.516

We are confident at 95% that the true proportion of all people who like the movie is between 0.484 and 0.516.

Step-by-step explanation:

We have the following info given:

\hat p = 0.5 represent the estimated proportion of all people who like the movie

n = 3850 represent the sample size selected

For the first question the sample size is n= 3850

For the second part they gives to us the margin of error:

ME = 0.016

We know that the confidence interval for a population proportion p of interest is given by:

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

And the margin of error is given by:

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

So then the confidence interval can be found with this formula:

\hat p \pm ME

And replacing we got:

0.5- 0.016 = 0.484

0.5+ 0.016 = 0.516

We are confident at 95% that the true proportion of all people who like the movie is between 0.484 and 0.516.

Answer:

Step-by-step explanation:

x=17

Let's solve your equation step-by-step.

6(x−5)=72

Step 1: Simplify both sides of the equation.

6(x−5)=72

(6)(x)+(6)(−5)=72(Distribute)

6x+−30=72

6x−30=72

Step 2: Add 30 to both sides.

6x−30+30=72+30

6x=102

Step 3: Divide both sides by 6.
