Answer:
364.5
Step-by-step explanation:
you would need a calculator for it, unless you can do exponential math at such a degree... if you're using a PC there's a good graphing calculator at Desmos.com, it can show you how a graph looks, which shows that when n is 7, the answer is 364.5. also it wouldn't be 1093.5 because the exponent is n-1 which means that while n could be 7, you need to take away 1 before using it as an exponent.

Answer:
Option B) is a continuous probability distribution          
Step-by-step explanation:
Properties of a normal probability distribution:
- The mean, mode and median of the data is same.
- It is a continuous probability distribution.
- The area under the curve is 1.
- The probability that any random variable X at a particular value is zero.
Thus, from the properties of normal distribution, the correct answer is:
Option B) is a continuous probability distribution
 
        
             
        
        
        
Answer: Your answer is d because if you solve for x you will get 180 and if you plug 180 into the equation it equals 700. 
 
        
                    
             
        
        
        
Her swimming rate can either be written as 1.6 laps per (one) minute or as 0.625 minutes per lap = 37.5 seconds per (one) lap.
In terms of number of laps per minute, the answer is 
20
 laps
12.5
 minutes
=
1.6
 laps per minute.
In terms of the number of minutes per lap, the answer is 
12.5
 minutes
20
 laps
=
5
8
=
0.625
minutes per lap. This is the same as 
0.625
min
lap
⋅
60
sec
min
=
37.5
sec

The faster she goes, the more laps she can do in a minute and the fewer minutes (or seconds) it takes her to do one lap.
