X=5

Explanation: 6x + 4 = 11x - 21
1). Subtract 4 from both sides and you will get 6x = 11x -25.
2). Subtract 11x from both sides and you should get -5x = -25.
3). Divide the -5 with -25 to get x alone and you should get X=5!

Check your work:
6(5) + 4 = 34 & 11(5) - 21 = 34
34=34.

Solve for Inequality

uysha [10]

Answer:

x > -1

Step-by-step explanation:

Divide the whole inequality by 9.

( $\frac{x}{3}$ +1)> $\frac{6}{9}$

Subtract 1.

$\frac{x}{3}$ > $\frac{2}{3}$ - 1

$\frac{x}{3}$ > - $\frac{1}{3}$

Multiply by 3.

x > -1

VladimirAG [237]

Answer:

Margin of error for a 95% of confidence intervals is 0.261

Step-by-step explanation:

<u>Step1:-</u>

Sample n = 81 business students over a one-week period.

Given the population standard deviation is 1.2 hours

Confidence level of significance = 0.95

Zₐ = 1.96

Margin of error (M.E) = $\frac{Z_{\alpha }S.D }{\sqrt{n} }$

Given n=81 , σ =1.2 and Zₐ = 1.96

<u>Step2:-</u>

<u /> $Margin of error (M.E) = \frac{Z_{\alpha }S.D }{\sqrt{n} }$ <u />

<u /> $Margin of error (M.E) = \frac{1.96(1.2) }{\sqrt{81} }$ <u />

On calculating , we get

Margin of error = 0.261

<u>Conclusion:-</u>

Margin of error for a 95% of confidence intervals is 0.261
