Answer:

1. X= - -4+y-z/3

Step-by-step explanation:

1. -6x-2y+2z=-8

1. Subtract -2y+2z from both sides -6x-2y+2z-(-2y+2z)=-8-(-2y+2z)

1. Simplify -6x=-8+2y-2z

1. Divide both sides by -6 -6x/-6 = - 8/-6+ 2y/-6 - 2y/-6

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

= $P(X$

Romashka-Z-Leto [24]

Answer:

$3600 per year into savings

Step-by-step explanation:

He makes 1500 dollars a month

1/5 of that goes into saving

1/5*1500 = 300

300 per month goes into savings

We want to know how much goes into savings per year

There are 12 months in a year, so we need to multiply by 12

300 per month * 12 months/ year = 3600 per year

$3600 per year into savings
