Otis measured the heights of several sunflowers. He found that their heights were 2,3,5,7, and 8 feet. Otis found that the mean was 5 feet and the range was 6 feet. Which numbers describe the center and spread of this data set? A. 6 feet describes the center, and 5 feet describes the spread. B. 8 feet describes the center and 2 feet describes the spread C. 5 feet describes the center, and 6 feet describes the spread D. 2 feet describes the center and 8 feet describes the spread.​

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

your answer is
