Solve for x. −3/4(x+2)=6 Enter your answer in the box
photoshop1234 [79]

Answer:

x = - 10

Step-by-step explanation:

−3/4(x+2)=6                                Multiply both sides by -4/3

- 4/3 * - 3/4 ( x + 2) = 6 * - 4/3    Simplify

(x + 2) = - 8                                  "Remove" the brackets

x + 2 = - 8                                    Subtract 2 from both sides.

x + 2 - 2 = - 8 - 2                         Simplify

x = - 10

How to Simplify (7^6)^2
LiRa [457]

Answer:

Well, since your question is asking how to simplify and not the actual answer itself, all we have to do is first simplify 7^6=117,649. Now we just take that number and make it 117,649^2. I hope im correct with the way i set up the equation even though the number is absurdly large

Automobile mechanics conduct diagnostic tests on 150 randomly selected new cars of particular make and model to determine the ex
Archy [21]

Answer:

\mathbf{Margin\;  of\;  error} =  .0942816

Step-by-step explanation:

Given

Sample size n = 150

Sample proportion {\widehat{(p)} = \frac{42}{150} = 0.28

Confidence interval = \frac{99}{100} = .99

Margin\;  of\;  error = z_{\frac{\alpha }{2}}\sqrt{\frac{{\widehat{(p)}}{(1 - \widehat{p})}}{n}}

\alpha = 1 - confidence interval = 1 - 0.99 = .01

margin\;  of\;  error = z_{\frac{.01 }{2}}\sqrt{\frac{(.28) (1 - 0.28)}{150}    

For 99\% confidence interval

        ( Z = 2.576 )

margin\;  of\;  error = z_{.005 }}\sqrt{\frac{(.28) (1 - 0.28)}{150}                  

margin\;  of\;  error = 2.576\times\sqrt{\frac{(.28) (1 - 0.28)}{150}

                           =  .0942816
