Serga [27]

Answer:

0.0159

Step-by-step explanation:

Given that a common practice of airline companies is to sell more tickets for a particular flight than there are seats on the plane, because customers who buy tickets do not always show up for the flight.

Here if X is the no of persons that do not show up, then X is binomial as each trial is independent with p = 0.04 and n =150 (no of tickets sold)

The plane is overbooked if more than 150 show up

i.e. less than 2 do not show up

Hence the probability that the airline overbooked this flight

= $P(X$

We can describe 3x 2 as an expression. How can we describe the parts of the expression ?

sattari [20]

Answer:

As you can see, x is a variable in both 3x 2 and 7x, and the variable x is multiplied by a number. In the first term, 3x 2, 3 is multiplied by the variable, so 3 is a coefficient. With 7x, 7 is multiplied by the variable. 7 is therefore a coefficient.
