Answer:
2.08%
Step-by-step explanation:
The probability of a snowfall on any given night is 1/8.
The probability that the father is telling the truth is 1 - 5/6, or 1/6.
Then:
1/6 x 1/8=1/48=0.0208, or 2.08% ............
Its 48. Random fact : 48 divided by 8 = 6. xD
The correct answer is d) 4x² - 4x + 1.
The area of a square is found by squaring the side length:
(2x-1)² = (2x-1)(2x-1) = 2x*2x - 2x*1 - 2x*1 - 1(-1) = 4x² - 2x - 2x + 1 = 4x²-4x+1
Answer:
- a/b = c/d
- a/c = b/d
- b/a = d/c
- c/a = d/b
Step-by-step explanation:
The possible proportions can be formed by dividing the equation ...
ad = bc
by any of the four products that consist of one left-side variable and one right-side variable.
Dividing by ab gives ...
d/b = c/a
Dividing by ac gives ...
d/c = b/a
Dividing by bd gives ...
a/b = c/d
And dividing by cd gives ...
a/c = b/d

<em>Comment on writing proportions</em>
Any proportion can be written in any of these four ways. It is generally convenient to choose the one that has the unknown variable as a numerator with a denominator of 1 (if possible).
