Condense the following logarithm: 5log_4(a) - 6log_4(b)​
grin007 [14]

Hi there! We are given the expression:

\large \boxed{5 log_{4}(a)  - 6 log_{4}(b) }

To condense or simplify the following logarithm. You have to remember these properties:

Properties - Logarithm

\large{ log_{b}(a)^{n}  = n log_{b}(a) } \\  \large{ log_{b}(a)  -  log_{b}(c)  =  log_{b}( \frac{a}{c} ) }

These two properties are what we need for our problem. Therefore,

\large{ log_{4}(a)^{5}  -  log_{4}(b)^{6} }

We use the log_b(a)^n = nlog_b(a) property to convert in the form above. Next, we use the second property.

\large{ log_{4}( \frac{ {a}^{5} }{ {b}^{6} } ) }

Answer

  • log base 4 of (a^5/b^6) is our simplifed form.

Any questions can be asked through comment as I may reply soon. Thanks for using Brainly! Have a good day and happy learning! :)

Answer:

a) True

b) Parameter

Step-by-step explanation:

We are given the following in the question:

An accounting professor wants to know the average GPA of the students enrolled in her class.

Population:

  • It is defined as the collection of all variables of interest.
  • A sample of individuals of interest is drawn from a population.

For the given case

Individuals of interest:

Students enrolled in accounting class

Population of interest:

Students enrolled in accounting class

Characteristic of interest:

Average GPA of the students enrolled in her class.

a) The population is all students enrolled in the accounting class.

The given statement is true as it contains all the observation of all the individuals of interest.

b) The computed average GPA of all the students enrolled in the class is 3.29

Statistic is a descriptive measure that describes a sample where as a parameter is a measure that describes the population.

Since 3.29 is the average of all the students enrolled in her class that is the average GPA of population.

Thus, 3.29 is a parameter.
