I have an unlimited supply of standard 6-sided dice. What's the fewest number of dice that I have to simultaneously roll to be a

t least 90% likely to roll at least one 6?
You may use a calculator to help you with the computations if you like -- in fact you'll almost certainly want to -- but your final answer should be a positive integer, and you should explain how you got it.

What does the "In" mean when, for example, you say (In5/6)

P( rolling 6) = 1/6
P(NOT rolling 6) = 5/6
P(AT least one 6) = 1 - 5/6
P(After x number of trials to obtain at least one 6) = 0.9
Then 0.9 = 1 - (5/6)ˣ

0.9 - 1 =  - (5/6)ˣ
- 0.1 =  - (5/6)ˣ   → (5/6)ˣ = 0.1

x(ln 5/6) = ln(0.1)

x = ln0.1) / ln(5/6)  = 12.63 ≈ 13 times

A polynomial P has zeros when x=0, x=-1/6 and x=-3 Whats could be the equation p?
erma4kov [3.2K]

Answer:

P(x) = x^{3} + \frac{19}{6} x^{2} + \frac{1}{2} x

Step-by-step explanation:

x(x + 1/6)(x + 3) = P

x(x^{2} + 3x + 1/6(x) + 1/2) = P

x (x^{2} + 19/6(x) + 1/2) = P

x^{3} + \frac{19}{6} x^{2} + \frac{1}{2} x = P(x)

Identify the graph of the equation. What is the angle of rotation for the equation?
borishaifa [10]

Answer:

d. parabola, 0°

Step-by-step explanation:

y² + 8x - 0

y² = -8x

Where x = cos t  ,  y = sin t

Sin² t = -8 Cos t

1 - Cos² t = -8 Cos t

- Cos² t + 8 Cos t + 1 = 0

t = 2лπ ± (3 + √10) , л∈Z

Angle of rotation

It’s asking for the area<br> Please help! Thank you!
Eddi Din [679]

Answer: x^2+9x+20

Step-by-step explanation:

To find the area you multiply the sides so it should be (x+4)(x+5) which is x^2+9x+20. Good luck!
