Your calculator should give you the answer to both.
3^3 = 3 * 3 * 3 = 27
∛(125) = ∛(5 * 5 * 5) = Three equal factors under a cube root sign give 1 factor on the left of the cube root sign. The other 2 are discarded.
∛(5 * 5 * 5) = 5∛1 = 5
Answer:

And from the problem we know the following:
represent the condition if the route is approved
represent the condition if the route is NOT approved
Then replacing in the formula for the expected value we got:

So then the expected number of new employees to be hired by the airline based on the conditions given is between 395 and 396.
Step-by-step explanation:
For this cae we can define the random variable X who represent the number of new employees to be hired by the airline and we can find the expected value with the following general formula:

And from the problem we know the following:
represent the condition if the route is approved
represent the condition if the route is NOT approved
Then replacing in the formula for the expected value we got:

So then the expected number of new employees to be hired by the airline based on the conditions given is between 395 and 396.
The right answer is the 2nd one.
It's using the quadratic equation
It would equal 3.14, because you're using pie (3.14) times the radius (divide the diameter by 2 to get your radius, which would equal 1), and then you square it.
