Which of the following is true regarding the solution to the logarithmic equation below?
lidiya [134]

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

\log_2(x+11)=4

Using properties of \logarithm we get

(x+11)=2^4             [\because \log_ax=b\Leftightarrow x=a^b]

x+11=16

x=16-11

x=5

The solution is x=5.

To check the solution, substitute x=5 in the given equation.

\log_2(5+11)=4

\log_2(16)=4

\log_22^4=4

4=4

LHS=RHS

Therefore, x-5 is a true solution because \log_2(16)=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.
