Answer:
18 feet 3 inches
Step-by-step explanation:
4 feet 7 inches + 6 feet 11 inches + 6 feet 9 inches =
10 feet 18 inches + 6 feet 9 inches =
16 feet 27 inches =18 feet 3 inches

Answer:

we can conclude at 95% of confidence that the true proportion of interest for this case is between 0.287 and 0.613
Step-by-step explanation:
The estimated proportion of interest is 
We need to find a critical value for the confidence interval using the normla standard distributon. For this case we have 95% of confidence, then the significance level would be given by  and
 and  .
. 
And the critical value is:
The confidence interval for the true population proportion is interest is given by this formula:  

Replacing the values provided we got:

And we can conclude at 95% of confidence that the true proportion of interest for this case is between 0.287 and 0.613
 
        
             
        
        
        
Answer:
.7 pi    Radians 
Step-by-step explanation:
There are pi radians in a 180 degrees :
    pi / 180   * 126  = .7 pi  Radians
 
        
                    
             
        
        
        
Answer:
(5, -2)
Step-by-step explanation:
In the coordinates (7, -5), 7 is the x-coordinate and -5 is the y-coordinate.
The transformation, (x-2 y+3), states that the x-coordinate, 7, must be subtracted by 2.
When subtracted by two, (7 - 2), the difference is 5.
The transformation, (x-2 y+3), states that the y-coordinate must be increased by 3. 
When added by 3, (-5 + 3), the sum is -2.
Therefore, the new coordinates are (5, -2).
