Suppose a gas station monitors how many bags of ice they sell along with the maximum daily temperature for 100 days. a gas station data analysis plots the data in a scatterplot with temperature, in degrees fahrenheit, on the horizontal axis and the number of bags of ice sword on the vertical axis. she calculates a linear correlation coefficient of r= 0.9972. the mean temperature is 83.8959 degrees fahrenheit with a standard deviation of 11.2921 degrees fahrenheit. the mean number of ice bags sold is 70.3873 with a standard deviation of 27.8 913.

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
