Answer: The probability is about 0.2%.
The probability of flipping heads one time is 0.5, 50% or 1/2.
To flip heads 9 times in a row, we have to multiply 1/2 by itself 9 times.
(1/2)^9 = 1/512 or about 0.2%
It should only happen once every 512 times.

I think there the same for each but I hope I helped
Ratio :
Width : Length
3 : 5
Let the factor be x
(3x)(5x) = 15x²
15x² = 135
x² = 9
x = √9
x = 3
Width = 3 x 3 = 9 cm
Length = 3 x5 = 15 cm
Answer: The dimension is 9cm by 15 cm

Answer:
Hopefully, the problem is worded as follows:
a after 3 years = A (1.08)^3 = 1.2597 A after 3 years (invested at end of year)
a after 2 years = A (1.08)^2 = 1.1664 A after 2 years
a after 1 year = A (1.08) = 1.08 A
a last year = A
adding the columns
4 a = 4.5061 A where A is the amount invested each year and a is the total worth of such an investment
or a = 1.12653 A
A = a / 1.12653 = 550,000 / 1.12653 = 488,226 for the total investment
Each year 488,226 / 4 must be invested = 122,057
