I really don't know if I'm doing this right and I have a test coming up (I only need the answer for the odds)

What is the horizontal distance between (−5/3, -2) and (4, -2)?

Nataly [62]

Answer:

-2?

Step-by-step explanation:

use y2-y1 over x2-x1 to find the answer. So you would do -2--5/3 over 4--2. The two negitives turn into a positive. SO it is now -2+5/3 over 4+2. -2+5/3= -1/3 over 4+2=6 it is now -1/3/6 which equals -2. So I think the answer is -2.<u> I do not know if you should trust me on this but I tried. </u>

An airline charges the following baggage fees: $25 for the first bag and $35 for the second. Suppose 51% of passengers have no c

Orlov [11]

Answer:

The average revenue per passenger is about $13.85

μ = $13.85

The corresponding standard deviation is $14.51

σ = $14.51

The airline should expect revenue of $1,662 with a standard deviation of $14.51 for a flight of 120 passengers.

Expected revenue = $1,662 ± 14.51

Step-by-step explanation:

An airline charges the following baggage fees:

$25 for the first bag and $35 for the second

Suppose 51% of passengers have no checked luggage,

P(0) = 0.51

33% have one piece of checked luggage and 16% have two pieces.

P(1) = 0.33

P(2) = 0.16

a. Build a probability model, compute the average revenue per passenger, and compute the corresponding standard deviation.

The average revenue per passenger is given by

μ = 0×P(0) + 25×P(1) + 35×P(2)

μ = 0×0.51 + 25×0.33 + 35×0.16

μ = 0 + 8.25 + 5.6

μ = $13.85

Therefore, the average revenue per passenger is about $13.85

The corresponding standard deviation is given by

σ = √σ²

Where σ² is the variance and is given by

σ² = (0 - 13.85)²×0.51 + (25 - 13.85)²×0.33 + (35 - 13.85)²×0.16

σ² = 97.83 + 41.03 + 71.57

σ² = 210.43

So,

σ = √210.43

σ = $14.51

Therefore, the corresponding standard deviation is $14.51

b. About how much revenue should the airline expect for a flight of 120 passengers? With what standard deviation?

For 120 passengers,

Expected revenue = 120×$13.85

Expected revenue = $1,662 ± 14.51

Therefore, the airline should expect revenue of $1,662 with a standard deviation of $14.51 for a flight of 120 passengers.

Which mathematical word describes both 27x and 6x in the expression 27x+6x

Leno4ka [110]

The mathematical word describing both 27x and 6x in the expression is "addition" or "sum"

<h3>How to use mathematical word to describe an expression</h3>

The mathematical expression is 27x + 6x.

Mathematical expression are combinations of numbers and variables ordered with operations.

Mathematical expression is a combination of numbers, variables, operators (such as addition, subtraction, multiplication or division etc.).

For the given case, the terms are 27x and 6x and the expression formed from them is 27x + 6x.

This simply implies both terms are summed together to give the expression 27x + 6x.

Therefore, the mathematical word describing both 27x and 6x in the expression is "addition" or "sum"

A moving company charges $40 plus $0.10 per mile to rent a moving van. Another company charges $10 plus $0.25 per mile to rent t

mote1985 [20]

We will use an equation to model both costs and set them equal to each other to figure out the value for n.

$40+0.10n=10+0.25n$

$30+0.10n=0.25n$

$30n=0.15n$

$200=n$

At 200 miles, the cost will be the same.

The function is used to convert temperature from Celsius (C) to Fahrenheit (F). The function C(K) = K − 273.15 is used to conver

jeka94

Answer:

The correct function for converting temperature from Kelvin to Fahrenheit is $F(K) = \frac{9(K - 273.15)}{5} + 32$

Step-by-step explanation:

Kelvin to Celsius function:

The function to convert a temperature from degrees Kelvin to degrees Celsius is given by:

$C(K) = K - 273.15$

Celsius to Fahrenheit function:

The function to convert a temperature from degrees Celsius to degrees Fahrenheit is given by:

$F(C) = \frac{9C}{5} + 32$

Which is the correct function for converting temperature from Kelvin to Fahrenheit?

In the equation to find F(C), we use C = C(K). So

$F(C) = \frac{9C}{5} + 32$

$F(C(K)) = \frac{9(K - 273.15)}{5} + 32$

$F(K) = \frac{9(K - 273.15)}{5} + 32$

The correct function for converting temperature from Kelvin to Fahrenheit is $F(K) = \frac{9(K - 273.15)}{5} + 32$
