Step-by-step explanation:

Thus, mean and median are same.
Answer:
0.6 (terminating), 0.5, 0.375
Step-by-step explanation:
I would assume you are wanting these in decimal form. In that case, you would have:
2/3 = 0.6 (terminating)
1/2 = 0.5
3/8 = 0.375
So we are given the expression:
÷ 
When we divide fractions, we must flip the second term and change the sign to multiplication:

And then we multiply across:

Then we can break apart all of the like variables for simplification:

When we simplify variables through division, we subtract the exponent of the numerator from the exponent of the denominator. So we then have:



So then we multiply all of these simplified parts together:

So now we know that the simplified form of the initial expression is:
.
Answer:
1%
Step-by-step explanation:
We use the simple interest equation of A=P(1+rt).
A-the total amount with interest earned
P-the initial amount or principal
r-rate
t-time in years
We substitute the values P=6900, A=6923, and t=0.33 since 4 months divided by 12 months is 0.333 years. We then solve for r.

Our final step is to divide both sides by 0.33.

This is the decimal of the rate. We convert to a percentage by multiplying by 100. 0.01(100)=1%.
Answer:
Step-by-step explanation:
a₂ = 9
a₃ = a₂-1.5
a₄ = a₃-1.5
a₅ = a₄-1.5
etc.
The terms have a common difference of -1.5, so the sequence is arithmetic.
