A movie production company is releasing a movie with the hopes of many viewers returning to see the movie in the theater for a second time. Their target is to exceed 30% of the viewers to want to see the movie again. The company shows the movie to a test audience of 200 people, and after the movie they asked the test audience if they would like to see the movie in theaters again. Of the test audience, 68 people said they would see the movie again. Is there evidence that the proportion of the viewers who want to see the movie again exceeds 30%

step-by-step explanation:

use that smart brain

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places

think the answer is 30 degrees. if not than it is 20 degrees. not 100% sure. let me know if it was right.
