Answer:
CI=P*(1 + R/100)^18
A=(CI + P) = P(1+R/100)^18
13500/P=1(100+R/100)^18
A/P=(100+R/100)^18
A/P=(100+R/100)^18
A=13500$ as (750 * 18)
(13500)/P=(1 +1.15/100)18
(13500)/P=(1+1.15/100)18
13500=((1.0115)^18
P=R$10989.02
Step-by-step explanation:
CI=Compound Interest
A=Amount
P=Principal.

150 is a good sample of a middle school and students at lunch is random again because most students eat lunch
Answer:
a = 22
b = 31
c = 13
Step-by-step explanation:
The sum is the same in each row, column, and diagonal.
One of the diagonals is already complete. The sum is:
16 + 25 + 34 = 75
So the first row adds up to 75:
a + 37 + 16 = 75
a = 22
The second row adds up to 75:
19 + 25 + b = 75
b = 31
And the third row adds up to 75:
34 + c + 28 = 75
c = 13
We can check our answer by finding the sum of each column and the other diagonal.
22 + 19 + 34 = 75
37 + 25 + 13 = 75
16 + 31 + 28 = 75
22 + 25 + 28 = 75
Answer:
The statement is false.
Step-by-step explanation:
Let a and b represent two odd integers.
The average (A) is defined by:
A=
In order to prove the statement, you have to show that it's true for all odd integers. But, to disprove it, you just have to find a counterexample where the statement is false.
Notice that it is easier to try to find a counterexample.
For example, a=3 and b=5
A= 
The result of the average is even, therefore the statement is false.
The previous calculation is a counterexample.
Undefined (not a real number)
The square root of -256 would result in an imaginary number so by terms, it's "not real". The imaginary number would be 16i. 16x 16 =256, but since it's negative, it's √16 √16i.
