Answer:
The rule says that to find the number of years required to double your money at a given interest rate, you just divide the interest rate into 72. For example, if you want to know how long it will take to double your money at eight percent interest, divide 8 into 72 and get 9 years.
Step-by-step explanation:
Answer:
it is 8^2.
Step-by-step explanation:
8 ^ 3 = 8 x 8 x 8
8^3/8 = 8 x 8 x 8 / 8
you cross one 8 on the bottom and the top which leaves you with 8 x 8 or 8^2
Answer:
The sample size is 
Step-by-step explanation:
From the question we are told that
The standard deviation is 
The precision is 
The confidence level is 
98%
Generally the sample size is mathematically represented as
Where 
is the level of significance which is mathematically evaluated as
%
and 
is the critical value of which is obtained from the normal distribution table as 2.326
substituting values
117.8 because angle at a point add up to 360 so 360 -(90 + 38.2+31.7+82.3) =117.8
Well, to solve, you would subtract 8 from both sides, which means x would end up equaling 32.
X=32
