Answer:
Option C.
Step-by-step explanation:
Note: It is given question and option "=" sing is missing. On some places it should be "=" instead of "=".
Consider the given equation is
Using properties of \logarithm we get
![[\because \log_ax=b\Leftightarrow x=a^b]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Clog_ax%3Db%5CLeftightarrow%20x%3Da%5Eb%5D)
The solution is x=5.
To check the solution, substitute x=5 in the given equation.
Therefore, x-5 is a true solution because .
Answer:
no, bcoz -1/4 is to the right of -3/4
The equation for the determination of the z-score is shown below.
z-score = (x - μ) / σ
where x is the value in which we need to determine the z-score, μ is the mean or the average, and σ is the standard deviation.
Substituting the known values,
z-score = (1,030.00 - 1,200) / 100 = -1.7
Therefore, the z-score of 1,030 is -1.7.
