The expression which is equivalent to the provided expression of variable x is,

<h3>What is the equivalent expression?</h3>
Equivalent expressions are the expression whose result is equal to the original expression, but the way of representation is different.
The given expression in the problem is,

Let the equivalent expression of this expression is f(<em>x)</em>. Thus,

The number, with negative power, can be written in the fraction of 1 with the same but positive power or exponent. Therefore,

Solve it further as,

Hence, the expression which is equivalent to the provided expression of variable x is,

Answer:
5:2
Step-by-step explanation:
18 and 45 are both multiples of nine, so I divided both sides by nine.
18/9 = 2
45/9 = 5
5 and 2 are prime numbers, so you can't simplify any further.
The IQR is 150 - 130 = 20. Using the 1.5(IQR) criterion we get 130 -1.5(20) = 100. Since the smallest observation of 85 is smaller than 100, it should be considered an outlier
