Answer:
C 36
Step-by-step explanation:
When we have to exponents to the same base, and we are dividing them, we can subtract the exponents
a^b ÷ a^c = a^ (b-c)
6^7 ÷ 6^5 = 6^(7-5)
                  = 6^(2)
                 = 36
 
        
                    
             
        
        
        
The major thing that differentiate microeconomics from macroeconomics is the object of study. Microeconomics refers to the study of economics at individual, group or business level while macroeconomics involves the study of economics on the national scale, that is the study of the economy of a nation. The economics of a nation is the combination of all the individuals, businesses, households, etc in a country.

Solution :
Given :
Sample mean, 
Sample size, n = 129
Sample standard deviation, s = 8.2 
a. Since the population standard deviation is unknown, therefore, we use the t-distribution.
b. Now for 95% confidence level,
    α = 0.05, α/2 = 0.025
   From the t tables, T.INV.2T(α, degree of freedom), we find the t value as 
   t =T.INV.2T(0.05, 128) = 2.34
   Taking the positive value of t, we get  
   Confidence interval is ,
   
  
  (32.52, 35.8) 
  95% confidence interval is  (32.52, 35.8) 
So with  confidence of the population of the mean number of the pounds per person per week is between 32.52 pounds and 35.8 pounds.
 confidence of the population of the mean number of the pounds per person per week is between 32.52 pounds and 35.8 pounds.
c. About  of confidence intervals which contains the true population of mean number of the pounds of the trash that is generated per person per week and about
 of confidence intervals which contains the true population of mean number of the pounds of the trash that is generated per person per week and about  that doe not contain the true population of mean number of the pounds of trashes generated by per person per week.
 that doe not contain the true population of mean number of the pounds of trashes generated by per person per week.
