Answer:

To check an answer for an equation, you can substitute the answer you've found in place of the variable you solved it for.

The value of the unknown, x, can be plugged into the equation. You can then compare both sides to see if they are equal.

For your given equation, let's substitute 1 for x in the equation you've given.

3x + 5 = x + 7

3(1) + 5 = 1 +7

Simplify this.

3 + 5 = 8

8 = 8

You know that 8 does equal 8, so your value for x is correct.

I hope this helps you ^^

Good luck :)

Answer:

The required probability is 0.0281

Step-by-step explanation:

Consider the provided information.

Air-USA has a policy of booking as many as 18 persons on an airplane that can seat only 17.

Studies have revealed that only 82% of the booked passengers actually arrive for the flight.

Therefore, the probability of a person arrive is 0.82

Find the probability that t if Air-USA books 18 persons, not enough seats will be available.

Probability that 18 persons arrive = (0.82)^{18}=0.0281

Hence, the required probability is 0.0281
