When you cannot simplify it further. The terms have no common factor besides 1 and A plus C does not have two numbers that multiply to the total and equal C.
Answer:
This can be solved by using the empirical rule for a normal distribution.
Step-by-step explanation:
A. The number of skateboards given is one standard deviation above the mean. Approximately 68% of the data points lie within the range plus and minus one standard deviation of the mean. Therefore the required percentage is:
68 + 16 = 84%.
B. The given number of skateboards is two standard deviations above the mean. Approximately 95% of the data points lie within the range plus and minus two standard deviations of the mean. Therefore the required percentage is:
5/2 = 2.5%
C.The given number of skateboards is one standard deviations below the mean. Therefore the required percentage is:
16%.
You would need to turn 4 4/9 and 2 7/9 into mix numbers. This would leave you with 50/9 - 25/9. Since the denominators are the same you just need to subtract the numerators 50 - 25 = 25. So the answer is 25/9
-4r+5=25 -4r=20 r=-5

Answer:
H) 2
Step-by-step explanation:
= 
[since 0 < x < (π/2) and 
]
= (1 + 1)
= 2
We know that in general,
by 
we mean the positive square root of x only.
