The amount of money Dillards owe Sheila and Carla is $0, while Sheila owe Carla $2.21
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Sheila has $10.00 dollars, and Carla has $15.00 dollars. Sheila's purchases come to $12.21. Carla's purchases come to $12.79. Hence:
Amount of money Dillards owe them = 25 - (12.21 + 12.79) = $0
Amount of money Sheila owe Carla = 12.21 - 10 = $2.21
The amount of money Dillards owe Sheila and Carla is $0, while Sheila owe Carla $2.21

Thirty four times 000 which I am assuming is just zeroes would be 0.
The probability that the average selling price of the 35 homes will be within $2000 of the true mean is 0.5753
First, we need to find the z-score and this is expressed according to the formula;
x is the sample space
is the mean value
is the standard deviation
Given the following parameters
Mean = $275,000
Standard deviation = $10,500
If the true mean is $273,000, then;
If the true mean is $277,000
This means that the z-score is between -0.1095 and 0.1095
Pr( -0.1095 ≤ z ≤ 0.1095)
According to the z table, the probability that the average selling price of the 35 homes will be within $2000 of the true mean is 0.5753

Answer:
The solution set we get is(x,y){(6/4 , 6)}....
Step-by-step explanation:
We have the system of equation:
y = 4x equation 1
8x + y= 18 equation 2
As we see that the first equation has a value of y. Now plug the value of y which is 4x in 2nd equation:
8x+y=18
8x+(4x)=18
12x=18
Divide both sides by 12.
12x/12= 18/12
x= 18/12
x= 6/4
Now plug the value x= 6/4 in equation 1.
y=4x
y=4(6/4)
4 will be cancelled out by 4
y = 6
The solution set we get is(x,y){(6/4 , 6)}....
Well the origanal price would be $1604
