Answer:
The statement represents the IDENTITY PROPERTY OF ADDITION.
Step-by-step explanation:
Here, the given expression is 8 + 0 = 8
IDENTITY ELEMENT : Identity element is a special type of element in a given set of system, such that any number remains UNALTERED if operated with the identity element.
⇒ a + X = X for, a ≡ IDENTITY ELEMENT
Now, 8 + 0 = 8
Comparing it with the above equation , we get
0 ≡ IDENTITY ELEMENT in the given Binary operation of Addition.
Hence, the statement represent the IDENTITY PROPERTY OF ADDITION.
Answer:
0.75
Step-by-step explanation:
<em>if you add 0.25 and 0.5 you get 0.75</em>
<em> 0.25</em>
+0.50
______
0.75
At the point when Hannah takes her first sweet from the sack, there is a 6/n chance it is orange.
This is because that there are 6 orange desserts and n desserts altogether.
When Hannah takes out her second sweet, there is a 5/(n-1) chance that it is orange.
This is because there are just 5 orange desserts let alone for an aggregate of n-1 desserts.
The possibility of getting two orange desserts in succession is the main likelihood increased by the second one: 6/n x 5/n–1
The question lets us know that the shot of Hannah getting two orange desserts is 1/3.
So: 6/n x 5/n–1 = 1/3
Now, rearrange this problem.
(6x5)/n(n-1) = 1/3
This gets to be:
30/(n² – n) = 1/3
Times by 3 on both sides:
90/(n² – n) = 1
What's more, doing likewise with (n² – n):
So (n² – n) = 90
Our answer is: n² – n – 90 = 0
