An airline company is considering a new policy of booking as many as 354 persons on an airplane that can seat only 330. (Past studies have revealed that only 88% of the booked passengers actually arrive for the flight.) Estimate the probability that if the company books 354 persons, not enough seats will be available

Answers

Answer 1
Answer:

Title:

See the explanation.

Step-by-step explanation:

It is given that, if 100 persons book their seats, then only 88 passengers come.

The probability of 1 passenger to come is (88)/(100) = 0.88.

There will not be enough seats only when, 331 or more than 331 passengers will come.

The probability of 1 passenger will not come is (1 - 0.88)= 0.12.

Out of 354 passengers the probability that n passengers will come is ^(354)C_n (0.88)^n (0.12)^(354 - n).

The required probability is ∑^(354)C_n (0.88)^n (0.12)^(354 - n), where 331\leq n \leq 354.

What number Could be added in the expression -4 -9 that the value of the expression is 0

Answers

Answer:

+13

Step-by-step explanation:

-4-9 gives -13

when +13 is added to -13 , the expression becomes +13+(-13) =13-13=0

if i’m understanding this correctly -9 + -4 is equal to -13 so wouldn’t you just add 13 to make it 0?

You are going on a road trip over a distance of 3000 miles with three friends. The car consumes 6 gallons of gas per 150 miles and gas costs $1.20 per gallon. If you want to split the cost of gas evenly between the four of you, how much should each of you pay? Please show step by step. Please HELP!! Answer soon. ​

Answers

Answer:

$54

Step-by-step explanation:

[3,000 / 100] x 6 = 180 - Liters of gas will be used on a 3,000 Km trip.

180 x 1.20 = 216 - total cost of gas over 3,000 Km trip.

216/4 = $54 - share of each one of the 4 people

What integer multiplied by 8 equals -96?

Answers

Answer:

-12

Step-by-step explanation:

Let "integer" = x

When x is multiplied by 8, it equals -96:

8x = -96

Isolate the variable x. Note the equal sign, what you do to one side, you do to the other. Divide 8 from both sides

(8x)/8 = (-96)/8

x = -96/8

x = -12

-12 is your answer

The similar triangle is the image of the bigger triangle after a sequence of transformations. What is the value of x?

Answers

Answer:

The value of x is:  2.5 units

Step-by-step explanation:

Two triangles are said to be similar if the ratio of the corresponding sides of the two triangles are equal.

i.e. if two triangles ΔABC and ΔDEF are similar such that the sides of the triangle ABC are a, b and c and the corresponding sides in ΔDEF are d,e and f respectively then we have:

(a)/(d)=(b)/(e)=(c)/(f)

Here we have the base length of the orange i.e. the quadrant above the x-axis as: 8 units

and the base length of the similar triangle i.e. triangle below x-axis as:  4 units.

i.e. we have: a=8 and d=4

and  b=5 and e=x

Hence, we have:

(5)/(x)=(8)/(4)

i.e.

x=(5* 4)/(8)

Hence, we have:

x=2.5

We have
(5)/(x) =  (8)/(4) \: so \n 20 = 8x \: so \n x =  (20)/(8) =  (10)/(4) =  (5)/(2) = 2 (1)/(2)
