The mean of a set of data is 3.90 and its standard deviation is 0.25. Find the z score for a value of 3.28. Round your answer to two decimal places.

Step-by-step explanation:

The z-score measures how many standard deviations a score X is above or below the mean.

It is given by the following formula:

In which is the mean and is the standard deviation.

The mean of a set of data is 3.90 and its standard deviation is 0.25. Find the z score for a value of 3.28. Round your answer to two decimal places

So it is Z when

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)

you estimate that the angle of elevation to the top of the 86th floor (the observatory) is 82 .the total height of the building is another 123 meters above the 86th floor.
