Answer:
American Roulette
1. The probability of losing a ’1st 12’ bet on a single spin is:
= 0.67
2. The probability of winning 7 out of the 10 total bets is:
= 0.23
Step-by-step explanation:
Possible outcomes in an American Roulette wheel = 38
Make-up of the outcomes = 18 black, 18 red and 2 green
Green outcomes are numbered 0 and 00
Number of wins for this person = 12
Probability of winning = 0.33 (12/36)
Number of possible losses for this person = 24
Probability of losing = 0.67 (24/36)
1. The probability of losing a '1st 12' bet on a single spin is:
= (36 - 12)/36
= 0.67
2. The probability of winning 7 out of the 10 total bets is:
Probability of winning = 12/36 * 7/10
= 0.23
Answer:
Guarantee of Tyre = 36,680 miles
Step-by-step explanation:
Given:
Mean = 46,000 miles
Standard deviation = 4,000 miles
Computation:
Assume;
x = guaranteed lifetime
P(X > x) = 99%
So,
P(X > x) = 0.99
So,
P(Z > z) = 0.99
So,
1 - P(Z > z ) = P(Z < z)
P(Z < z) = 0.01
So, in z table value of z = -2.33
x = μ + [z x σ]
x = 46,000 + [-2.33 x 4000]
x = 36,680
Guarantee of Tyre = 36,680 miles
Answer:
angle FBE
Step-by-step explanation:
By using the formula, the shortest angle is facing the shortest side
so the shortest angle is angle FBE
Line v passes through points (1, 12) and (10, 7). The slope of line w as improper fraction is ![\frac{9}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7B5%7D)
<u>Solution:</u>
Given, two points are (1, 12) and (10, 7)
We have to find the slope of a line that is perpendicular to line passing through the above given two points.
Slope of a line that pass through
is given as:
![m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_%7B2%7D-y_%7B1%7D%7D%7Bx_%7B2%7D-x_%7B1%7D%7D)
![\text { Here, in our problem, } x_{1}=1, y_{1}=12 \text { and } x_{2}=10, y_{2}=7](https://tex.z-dn.net/?f=%5Ctext%20%7B%20Here%2C%20in%20our%20problem%2C%20%7D%20x_%7B1%7D%3D1%2C%20y_%7B1%7D%3D12%20%5Ctext%20%7B%20and%20%7D%20x_%7B2%7D%3D10%2C%20y_%7B2%7D%3D7)
![\text { slope } m=\frac{7-12}{10-1}=\frac{-5}{9}](https://tex.z-dn.net/?f=%5Ctext%20%7B%20slope%20%7D%20m%3D%5Cfrac%7B7-12%7D%7B10-1%7D%3D%5Cfrac%7B-5%7D%7B9%7D)
So, slope of line v is ![\frac{-5}{9}](https://tex.z-dn.net/?f=%5Cfrac%7B-5%7D%7B9%7D)
Since<em> </em>line w is perpendicular to v,<em> the product of their slopes equals -1</em>
![\text { slope line } v \times \text { slope of line } w=-1](https://tex.z-dn.net/?f=%5Ctext%20%7B%20slope%20line%20%7D%20v%20%5Ctimes%20%5Ctext%20%7B%20slope%20of%20line%20%7D%20w%3D-1)
![\frac{-5}{9} \times \text { slope of line } w=-1](https://tex.z-dn.net/?f=%5Cfrac%7B-5%7D%7B9%7D%20%5Ctimes%20%5Ctext%20%7B%20slope%20of%20line%20%7D%20w%3D-1)
![\text { Slope of line } w=\frac{9}{-5} \times(-1)=\frac{9}{5}](https://tex.z-dn.net/?f=%5Ctext%20%7B%20Slope%20of%20line%20%7D%20w%3D%5Cfrac%7B9%7D%7B-5%7D%20%5Ctimes%28-1%29%3D%5Cfrac%7B9%7D%7B5%7D)
Hence, the slope of line w as improper fraction is ![\frac{9}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7B5%7D)
