Answer:
OPTION A
OPTION B
OPTION C
Step-by-step explanation:
Irrational numbers are the subset of real numbers. Their decimal representation neither form a pattern nor terminate.
OPTION A: 
This is equal to 
.
is non-terminating. So, it is an irrational number. Hence, the reciprocal of an irrational number would also be irrational. So, OPTION A is irrational.
OPTION B: 
This is equal to 
. Using the same logic as Option A, we regard OPTION B to be irrational as well.
OPTION C: 
This is equal to 
.
Both 
and 
are irrational. So, the product and the reciprocal of the product is irrational as well. So, OPTION C is an irrational number.
OPTION D: 
16 is a perfect square and is a rational number. 
= 
. This is equal to 0.25, a terminating decimal. So, OPTION D is a rational number.
OPTION E: 
4 is a perfect square as well. 
, a terminating decimal. So, OPTION E is a rational number.
Answer:
<h2>H = 60° </h2>
Step-by-step explanation:
To find angle H we use tan
tan ∅ = opposite / adjacent
From the question
The opposite is 2√21
The adjacent is 2√7
So that's
tan H = 2√21/ 2√7
H= tan-¹ 2√21/ 2√7
<h3>H = 60° </h3>

What's the question? what are you asking?
The probability that the new UNC-CH logo will be profitable is <u>0.9897 </u>while the probability for NC State will be <u>0.9600.</u>
<h3 /><h3>What is the probability that the brands will be successful?</h3>
The probability that the UNC-CH logo is successful is:
= Favorable odds / Total odds
= 96 / (96 + 1)
= 0.9897
The probability that the NC State logo is profitable is:
= Favorable odds / Total odds
= 24 / (24 + 1)
= 0.9600
There is less than a 3% variation in both logos' profitablility probability so the company should not spend 4 times more on UNC-CH.
