A store opens at 8am. From 8 until 10 customers arrive at a Poisson rate of four an hour. Between 10 and 12, they arrive at a Po

SVETLANKA909090 [29]

Answer:

The probability distribution of the number of customers that enter the store on a given day is:

$P(x=k)=\frac{57^ke^{-57}}{k!}$

Step-by-step explanation:

To calculate a parameter for the given day, we have to calculate what is the average arrival rate for the day.

This can be done with the data given:

1) From 10 to 12, 8 arrival/hour: 16 expected arrivals in this period

2) From 12 to 2, 8 to 12 arrival/hour (average: 10 arrivals): 20 expected arrivals in this period.

3) From 2 to 5, from 10 to 4 arrival/hour (average: 7 arrivals): 21 expected arrivals in this period.

The total expected arrivals in a day are: 16+20+21=57 arrivals/day.

Then, the probability distribution of the number of customers that enter the store on a given day is:

$P(x=k)=\frac{57^ke^{-57}}{k!}$

For logarithmic equations,

log

b ( x ) = y

logb(x)=y

is equivalent to b y = x

by=x

such that x > 0

x>0 , b > 0

b>0 , and b ≠ 1

b≠1

.In this case, b = 5

b=5 , x = 25

x=25 , and y 2

y=2 .

b = 5

b=5

x =

x=25

y = 2

y=2

Substitute the values of b

b , x

x , and y

into the equation

b y =

by=x

The cost of going to a drive-in movie theater is $5. 50 per person plus $2. 75 per car. Use the dropdown menu to create an algeb

Pie

The algebraic equation which shows that the number of x people can go to the drive-in with one car for $19. 25 is,

$5.50x+2.75=19.25$

<h3>How to write algebraic equation?</h3>

Algebraic equation are the expression which consist the variables, coefficients of variables and constants.

The algebraic expression are used represent the general problem in the mathematical way to solve them.

Steps to write down the simple algebraic equation-

Identify all the factors of the expression.
Assume a variable for the changing values.
Put a coefficient for the variable, if there is any rate of change of variable.
Use constant numbers for the fixed values.

The cost of going to a drive-in movie theater is $5.50 per person plus $2.75 per car. It has to create an algebraic equation that shows how many people can go to the drive-in with one car for $19. 25.

Suppose the total number of people in the car for drive-in movie theater is x. Thus, the cost of the x person to watch the movie is,

$C=5.50x$

As the cost of one car is $2.75. Thus, the total cost of watching a movie by x person will be,

$C=5.50x+2.75$

Now, the total cost, drive-in with one car for $19. 25. This cost must be equal to the above expression for total cost. Therefore,

$C=5.50x+2.75=19.25$

Hence, the algebraic equation which shows that the number of x people can go to the drive-in with one car for $19. 25 is,

$5.50x+2.75=19.25$
