Answer:
85
Step-by-step explanation:
12 in = 1 ft
first you need to convert 60ft to in:
60 * 12 = 720in
then divide 720(the amount of space you are covering by 8.5
720/8.5 = 84.7
then i guess you can round it to a full revolution so it would be 85
 
        
             
        
        
        
Answer:
65.3658 inches
Step-by-step explanation:
Let X be the height of a woman randomly choosen. We know tha X have a mean of 63.6 inches and a standard deviation of 2.5 inches. For an x value, the related z-score is given by z = (x-63.6)/2.5. We are looking for a value 
 such that 
, but, 
, i.e., 
 is the 76th percentile of the standard normal distribution. So, 
, 
. Therefore, the height of a woman who is at the 76th percentile is 65.3658 inches.
 
        
             
        
        
        
To factor, we always have to look for common factors in the numbers given to us. In this case, in 1/2 and 6, the common factor is 1/2. Therefore, we will have to factor like so:
1/2d + 6 = 1/2 (d + 3)
Hope this helps!
