Answer:
41/24 or 1 17/24
Step-by-step explanation:
2 3/8=19/8
-2/3+19/8
-16/24+57/24
41/24
 
        
                    
             
        
        
        
To find the area of the trapezoid you add the two bases then multiply by the base and divide by 2. 
B1+b2= 24+16=40
40*h=40*12=480
480/2=240
D. 240 square feet.
        
             
        
        
        
-7x^2 - 6x^2 + 3x + 5x - 5 + 2
-13x^2 + 8x - 3

Answer:  0.701
Step-by-step explanation:
Formula :   , where
 , where  significance level ,
 significance level ,  Population standard deviation, n= sample size.
 Population standard deviation, n= sample size.
As per given,  n= 22
 
Critical z- value for 90% confidence level : 
Then,
  
Hence ,  error bound (EBM) of the confidence interval with a 90% confidence level= ± 0.701
