Two 2 1/3 + 2 1/3 = 4 2/3
8/1 - 4 2/3 =
14/3 - 8/1 = 6/2
We know there are 4 suites the deck can be divided into, and two of the 4 are black. So you divide 2/4, and get 1/2. So the probability that a black card will be chosen is 1/2.
Answer:
Angle A = 97.5º
Step-by-step explanation:
Supplmentary means 2 angles that equal 180º. So we already have 1 angle, so now all we have to do is subtract 82.5 from 180.
180 - 82.5 = 97.5
Answer:
![P=7.62*10^{-26}](https://tex.z-dn.net/?f=P%3D7.62%2A10%5E%7B-26%7D)
Step-by-step explanation:
From the question we are told that:
Available plants:
44 red bulbs
44 purple bulbs
Generally the equation for Total possible arrangement is mathematically given by
![n= 88!/(44!*44!)](https://tex.z-dn.net/?f=n%3D%2088%21%2F%2844%21%2A44%21%29)
![n=2.6*10^{25}](https://tex.z-dn.net/?f=n%3D2.6%2A10%5E%7B25%7D)
Since
Its either
All 44 red bulbs and All 44 purple bulbs next to each other in one row
OR
All 44 purple bulbs and All 44 Red bulbs next to each other in one row
Therefore
Probability is
![P=\frac{2}{2.6*10^{25}}](https://tex.z-dn.net/?f=P%3D%5Cfrac%7B2%7D%7B2.6%2A10%5E%7B25%7D%7D)
![P=7.62*10^{-26}](https://tex.z-dn.net/?f=P%3D7.62%2A10%5E%7B-26%7D)
Answer:
The area of any regular polygon is given by the formula: Area = (a x p)/2, where a is the length of the apothem and p is the perimeter of the polygon.
