Many people say the civil justice system is overburdened. many cases center on suits involving businesses. the following data are based on a wall street journal report. researchers conducted a study of lawsuits involving 1908 businesses ranked in the fortune 1000 over a 20-year period. they found the following distribution of civil justice caseloads brought before the federal courts involving the businesses. note: contracts cases involve disputes over contracts between businesses. case type number of filings (in thousands) contracts 107 general torts (personal injury) 191 asbestos liability 49other product liability 38all other 21make a pareto chart of the caseloads.

1: -2 3/4, -2 1/2, -14, 0, 3, 8 1/3

2: -4, -3, -2 1/2, -2 1/4, 3 1/4,

step-by-step explanation:

a. is correct

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
