Answer:
Step-by-step explanation:
<u>Rational Numbers</u>
A rational number is any number that can be expressed as a fraction
for a and b any integer and b different from 0.
As a consequence, any number that cannot be expressed as a fraction or rational number is defined as an Irrational number.
Let's analyze each one of the given options
The first part of the number is indeed a rational number, but the second part is a square root whose result cannot be expressed as a rational, thus the number is not rational
The second part is an exact square root (resulting 4) but the first part is a known irrational number called pi. It's not possible to express pi as a fraction, thus the number is irrational
The square root of 121 is 11. It makes the whole number a sum of a rational number plus an integer, thus the given number is rational
As with the first number, the square root is not exact. The sum of a rational number plus an irrational number gives an irrational number.
Correct option:
Answer: 
Step-by-step explanation:
Since, Here the smaller number = 2n - 1
Since, Numbers are consecutive.
Therefore, remaining numbers are 2n - 1 + 2 , 2n - 1 + 2 + 2
= 2n +1, 2n +3
Thus, the sum of these all numbers = 2n - 1 + 2n + 1 + 2n +3
= 
( By equating the like terms)
Answer:
1/3 or 0.333333
Step-by-step explanation:
The question talks about a die that was tossed once and we are now asked to find the probability that it is a figure greater than 4
---A die has 6 faces with the numbers 1,2,3,4,5 and 6 one on each of
the six faces.Considering an unbaised die the probability of any of the faces to appear in a single roll is 1/6.
So, P(1)=P(2)=P(3)=P(4)=P(5)=P(6)=1/6
Now that numbers greater than 4 are 5 and 6
So it can be P(5) or P(6)= P(5)+P(6)=2/6 = 1/3 or 0.33333
Answer 1/3 or 0.33333
I believe it is c/6. Please correct me if I'm wrong.
I honestly don't know if this is right but it may make sense:
x is the event of picking up a rotten orange.
Probability that x is more than or equal to 1
= 1 - p(x=0)
so use binomialpdf on calculator
where trial is 4, p = 1/12(5/60), x = 0
1 - binoomialpdf(4, 1/12, 0)
and u get 0.294
