To determine what students at a school would be willing to do to help address global warming, researchers take a random sample o

f 100 students. The students answer the questions, "How high of a tax would you be willing to add to gasoline (per gallon) in order to encourage drivers to drive less or to drive more fuel-efficient cars?" and, "Do you believe (yes or no) that global warming is a serious issue that requires immediate action?" The researchers want to compare the mean response on gasoline taxes (the first question) for those who answer yes and for those who answer no to the second question. (a) Identify the response variable and the explanatory variable. What is the response variable?

Find the geometric mean between 6 and 48 given the sequence (3,6,12,24,48,96)
Sedaia [141]

Answer:

16.97

Step-by-step explanation:

the geometric mean value of a set of n numbers is the nth root of the product of all n numbers.

so, here this means

gm =  \sqrt[6]{3 \times 6 \times 12 \times 24 \times 48 \times 96}

this would be 16.97

but careful, the problem only asks for the gm between 6 and 48 of the sequence.

so, we actually only consider the subset 6, 12, 24, 48.

therefore

gm =  \sqrt[4]{6 \times 12 \times 24 \times 48}

this is also

gm =  \sqrt[4]{3 \times 2 \times 3 \times 2 \times 2 \times 3 \times 2 \times 2 \times 2 \times 3 \times 2 \times 2 \times 2 \times 2}

=  \sqrt[4]{ {3}^{4} \times  {2}^{10}  }

=  \sqrt[4]{ {3}^{4}  \times  {2}^{4}  \times  {2}^{4}  \times  {2}^{2} }

= 3 \times 2 \times 2 \times  \sqrt[4]{ {2}^{2} }

= 12 \times  \sqrt{2}

so, we could specify the result as that simple expression

or calculate it

gm = 16.97

hey, the result is the same as for the complete sequence.

coincidence ? no, it is not. but that is a subject for a different question.
