Given question is 4√6/√30
by rationalizing the denominator
4√6x√30/√30x√30
= 4√6x30/√30²
=4x√180/30 (i)
by solving the √180
√180=6√5
putting the value of √180 in (i)
=4x6√5/30
=24√5/30
=4√5/5 is the right answer.
Answer:
2x-3 = -11
Step-by-step explanation:
|2x-3| = 11
by definition of absolute numbers,
2x-3 = 11 (given)
or
2x-3 = -11 (answer)
Given:
The two way table.
To find:
The conditional probability of P(Drive to school | Senior).
Solution:
The conditional probability is defined as:

Using this formula, we get
...(i)
From the given two way table, we get
Drive to school and senior = 25
Senior = 25+5+5
= 35
Total = 2+25+3+13+20+2+25+5+5
= 100
Now,


Substituting these values in (i), we get




Therefore, the required conditional probability is 0.71.
16 is the answer when multiplied by each side
Here, 2 1/4 r = 10
9/4 r = 10
r = 10*4 /9
r = 40 / 9
r = 4 4/9
In short, Your Answer would be Option C
Hope this helps!
