4.5 pounds
72 ounces
HOW-TO:
1. we know that 1 pound is 16 ounces.
So let's find how many of 16 are needed for 72.
72 ÷ 16 = 4.5
Use that answer and multiply it by the number of pounds per 16 ounces.
You get 4.5 pounds.
 
        
             
        
        
        
6m² + 7m should be the answer
        
             
        
        
        
Answer:
Yes, The analysis involves a statistical test.
The hypothesis are 
Step-by-step explanation:
Consider the provided information.
Testing 500 right-handed participants on the reaction time of their left and right hands to determine if there is evidence for the claim that the right hand reacts faster than the left.
Yes, The above analysis involves a statistical test.
Where claim is right hand reacts faster than the left hand.
If right hand reacts faster that means the reaction time of right hand should be smaller than the reaction time of left hand.
Let  to be the average reaction time of their right hands for the right-handed participants and
 to be the average reaction time of their right hands for the right-handed participants and  to be the average reaction time of their left hands.
 to be the average reaction time of their left hands.
Therefore, the hypothesis are 
 
        
             
        
        
        
Step-by-step explanation:
 If were estimating, 39 is pretty close to 40 and 40x6 is 240 pounds. if we are getting exact about it, then 234 pounds
 
        
             
        
        
        
Answer:
Then the total area is  116 cm^2 which agrees with answer D
Step-by-step explanation:
Notice we need to calculate the area of two rectangles (one larger at the bottom and a smaller one on top)
The Area of a rectangle is the product: base x height
In our case :
Area of Big rectangle = 12 cm x 7 cm = 84 cm^2
Area of smaller rectangle = 8 cm x 4 cm = 32 cm^2
Then the total area is: 84 cm^2 + 32 cm^2 = 116 cm^2
