Solve each system of equations by substitution. 2x + 2y = 3 x - 4y = -1

Shtirlitz [24]

Step-by-step explanation:

2x + 2y = 3 ( x2 for everything in the equation)

x - 4y = -1

4x+ 4y = 6

x - 4y = -1

Add the 1st line to the 2nd line to get rid of the y:

5x = 5

x - 4y = -1 ( you can pick any line from this system to be the second equation in this step, you can put 2x + 2y = 3 or 4x+ 4y = 6, anything above this step, but to make it simple chose the one you think is the easiest)

Solve for x, then plug the x value into the 2nd equation

x = 1

1 - 4y = -1

x = 1

-4y = -2 =) y = 1/2

x = 1

y= 1/2

Answer:

$H_{0}: \mu \leq 600\text{ dollars}\\H_A: \mu > 600\text{ dollars}$

Step-by-step explanation:

We are given the following in the question:

Manager's claim: The mean guest bill for a weekend is $600 or less.

A member of the hotel’s accounting staff noticed that the total charges for guest bills have been increasing in recent months.

A sample of weekend guest bills were collected to test the manager’s claim.

We design the null and alternate hypothesis in the following manner:

$H_{0}: \mu \leq 600\text{ dollars}\\H_A: \mu > 600\text{ dollars}$

Conclusion when null hypothesis cannot be rejected:

When we fail to reject the null hypothesis and accept the null hypothesis, thus, we have enough evidence to support the manager's claim that the mean guest bill for a weekend is $600 or less.

Conclusion when null hypothesis can be rejected:

When the null hypothesis is rejected, we accept the alternate hypothesis.

Thus, there are not sufficient evidence to support the manager's claim that the mean guest bill for a weekend is $600 or less.
