Write the inequality:<br><br> Two less than twice a number is less than a half.
Art [367]

Answer:

2x-2<1/2

Step-by-step explanation:

when the problem says "two less than" it means we are subtracting 2 from something, in this case, that something is "twice a number" as the problem states. So we would write 2x where x is a variable that represents any number so we have 2x-2<1/2.

<h3>Answer: 10^(1/2)</h3>

When we use an exponent of 1/2, it is the same as a square root. The more general rule is

\sqrt{x} = x^{1/2}

In this case, we plug in x = 10.

The use of a fractional exponent is handy when you want to deal with things like cube roots on a calculator. This is because

\sqrt[3]{x} = x^{1/3}

Many calculators don't have a button labeled \sqrt[3]{} but they have the button x^y to allow fractional exponents.

Last step

Expected value=$7.50+$8.80

Expected value=$16.30

Therefore the average baggage-related revenue per passenger is $16.30 per passenger.
