Answer:
Ans= 6720 ways
Step-by-step explanation:
From Combination rule from Permutation and Combination, nCr
We use 8^C3 or 8C3,
8x7x6x5x4x3x2x1
-------------------------- =6,720
3x2x1
or
8x7x6x5x4x3! /3!, here the 3! cancels each other out, and we're left with 8x7x6x5x4, which equals 6720.
answer : 4407,4408
because 8815/2 = 4407.5 so you take away the .5 to find one number and you add .5 for the other
Answer:
The coordinates of the point P is -3
Please see attached number line
Step-by-step explanation:
The given information are;
The length of the given number line = The line extends from -30 to +10
The location of major tick marks = Every ten numbers
The location of minor tick marks = Every number
The location of the point P = Three ticks to the left of 0
Therefore, the coordinates of the point P = -3
Answer:
0.9986
Step-by-step explanation:
- Prob (Machine tool actually fails) = 0.04
- So, Prob (Machine tool actually functions) = 1 - 0.04 = 0.96
- Prob (functional machine tool claimed fail) = 0.08
- So, Prob (functional machine tool claimed functional) = 1- 0.08 = 0.92
- Prob (fail machine tool claimed fail) = 0.97
- So, Prob (fail machine tool claimed functional) = 1- 0.97 = 0.03
Prob A: P [Machine tool indicated (claimed) functional] :- Functional machine tool or fail machine tool claimed functional = (0.96)(0.92) + (0.04)(0.03) = 0.8844
Prob B: P [Machine tool actually function when passed by QAs] = (0.96)(0.92) = 0.8832
Prob (A given B) = P (A & B) / P (A)
= 0.8832 / 0.8844 = 0.9986
Answer:
31.6
Step-by-step explanation:
80 * .55 = 48.4 (Current amount of water)
80 - 48.4 = 31.6 (Needed amount of water)
