The U. S Census Bereau reported that the mean annual salary in 2002 was $51,194 for an individual whose highest degree was a bachelor's. A government economist believes that the mean anual salty for individuals whose highest degree is a bachelor is different today. She obtains a random sample of 300 employed adults whose highest degree is a bachelors and determine the mean annual salary to be $55,988 with a population standard deviation of $26,855. Text the economists claim at the a=0.05 significance. Fine the z-score. HELP

answer: its c because when it has a magnet next to it it will move away from the mixture. hope this

step-by-step explanation:

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
