Answer:
The answer is A.
Step-by-step explanation:
The answer is A because an obtuse angle rounds to 120 degrees, then you divide it by 6 which is A.
2^10/5 = 2^2 = 4

Answer:
B.The exponent of the solution is –12, the difference of the original exponents.
C.The coefficient of the solution must be greater than or equal to one but less than 10.
D.The quotient is 3.0 × 
Step-by-step explanation:
We are finding the quotient of the expression below in scientific notation

The following conclusions can be drawn
B.The power of 10 in the solution is –12, the difference of the original exponents.
C.The coefficient is 3, which is greater than or equal to one but less than 10.
D.The quotient is 3.0 × 
the answer is 11/4
The unit rate of change between variables is the quotient between the difference between y-values and the difference between x-values

As for the reason the average life expectancy of a Roman who reaches the age of 30 being so much higher than the average expectancy overall, that's simply a matter of taking the average of 50 and 80, verses the average of 1,6,20,50,80. Let's illustrate that by calculating the average life expectancy of a Roman at birth, and after age 30.
For birth, there's 5 ranges, each of which has the same probability. They are
[0,2]: Midpoint = 1. Probability = 0.2. Product = 1*0.2 = 0.2
[2,10]: Midpoint = 6. Probability = 0.2. Product = 6*0.2 = 1.2
[10,30]: Midpoint = 20. Probability = 0.2. Product = 20*0.2 = 4
[30,70]: Midpoint = 50. Probability = 0.2. Product = 50*0.2 = 10
[70,90]: Midpoint = 80. Probability = 0.2. Product = 80*0.2 = 16
Sum = 0.2 + 1.2 + 4 + 10 + 16 = 31.4
But upon reaching 30, there is no longer a mere 0.2 probability for those last 2 slots. The chart looks like
[30,70]: Midpoint = 50. Probability = 0.5. Product = 50*0.5 = 25
[70,90]: Midpoint = 80. Probability = 0.5. Product = 80*0.5 = 40
Sum = 65
If you look at each possible range of ages, the actual life expectancy is
at birth: 31.4 years
after age 2: 39 years
after age 10: 50 years
after age 30: 65 years
after age 70: 80 years</span>
