Box A is 4. 4 is 5% of the total boxes.
5% = 1/20, so multiply whatever number that's 5% of the total by 20 to get the total.
4 x 20 = 80.
There are 80 marbles total.
Hope this helps!
        
                    
             
        
        
        
Answer:
x=5
Step-by-step explanation:
We can use the Triangle Angel Bisector Theorem
AB             2x-1
----------= --------------
AC               3x
9              2x-1
----------= --------------
15               3x
Using cross products
3x*9 = 15*(2x-1)
Distribute
27x = 30x-15
Subtract 30x from each side
27x-30x = 30x-30x-15
-3x = -15
Divide by -3
-3x/-3 =-15/-3
x =5

Answer:
a range of values such that the probability is C % that a rndomly selected data value is in that range
Step-by-step explanation:
complete question is: 
Select the proper interpretation of a confidence interval for a mean at a confidence level of C % . 
a range of values produced by a method such that C % of confidence intervals produced the same way contain the sample mean 
a range of values such that the probability is C % that a randomly selected data value is in that range
 a range of values that contains C % of the sample data in a very large number of samples of the same size 
a range of values constructed using a procedure that will develop a range that contains the population mean C % of the time 
a range of values such that the probability is C % that the population mean is in that range
 
        
             
        
        
        
The answer is <u><em>0.76075</em></u>!
