−2(x+3)+6x

Distribute:

=(−2)(x)+(−2)(3)+6x

=−2x+−6+6x

Answer:

Check the explanation

Step-by-step explanation:

Part (A)

Kindly check the First attached image below to get the explanation the part A question.

Part (B)

As calculated in part (A), if we have 40 numbers of buns and hot dogs, there are no leftovers.

So every multiple of 40, will ensure no leftovers.

40, 80, 120, 160, 200, 240, 280, 320...

since 300 people are attending, 320 such buns and hot dogs are required.

packages of Bun = 320/8 = 40

packages of hot dogs = 320/10 = 32

(bun package,hot dog package) = (40,32)

Part (D)

In part (C), it came out the ratio

(buns packages : patties packages : jar of pickles) = (3:2:4)

Kindly check the Second attached image below

so to feed 420 people,

24*k > 420 such that minimum value of k

k = 18

so total 432 hamburgers will be formed.

Bun packages = 432/8 = 54

Patties packages = 432/12 = 36

Pickle jar = 432/6 = 72

so answer is (bun package, patties package, pickle jar) = (54,36,72)

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

= $P(X$
