Answer:
Percentage of balls which are red = 80%.
Step-by-step explanation:
Let the probability of drawing a red ball be x then the probability of drawing a white ball is 1-x.
There are 5C3 = 10 ways of getting 3 reds in 5 draws so the probability of this is 10* x^3 * (1 - x)^2.
The probability of getting 1 red in 5 draws = 5C1 * x (1-x)^4.
The first probability is 32 times the last.
So we have the equation:
10x^3(1 - x)^2 / 5x(1 - x)^4 = 32
2x^2 / (1 - x)^2 = 32
2x^2 = 32(1 -x)^2
2x^2 = 32( 1 - 2x + x^2)
2x^2 = 32 - 64x + 32x^2
30x^2 - 64x + 32 = 0
15x^2 - 32x + 16 = 0
(5x - 4)(3x - 4) = 0
x = 0.8, 1.333...
The probability must be < 1 so x = 0.8 = 80%.
Answer:
L= 11
Step-by-step explanation:
Formula to find the length when you know the area:
L = A/W
So the equation for this one is:
L = 93 1/2 ÷ 8 1/2
Simplify:
L = 11
To be sure of your answer you multiply the L x W = A
11 x 8 1/2 = 93 1/2

Answer:
The answer is 1.65 miles.
Step-by-step explanation:
To get this answer you need to convert 3/4 to a decimal, 0.75. Then multiply 0.75 by 2.2 to get 1.65.
