after 5 points are subtracted from every score, the sample mean is found to be m = 24. what was the mean for the original sample?

The mean of original sample is 29.

Step-by-step explanation:

After 5 points are subtracted from every score, the sample mean is found to be m = 24

So, the mean for the original sample was =

Here we are talking about mean so 5 points are subtracted from every score. when we are talking in terms of mean, 5 will be added to the mean, that will give 5 added to every score.

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
