Which of the following equations is written in standard form?

Harlamova29_29 [7]

Standard Form is ax + by = c, where a, b, and c are not fractions and a is not negative.

So, you can go through each of your options to see which ones work with those rules.

A. 2.5x + 3y = 12 No, this is not in Standard Form. 2.5 can be rewritten as 2<span> $\frac{1}{2}$ , menaing A is a fraction, which you can't have.

B. -10x - 3y = 1 No, this is not in Standard Form. A is -10, but A can't be negative.

C. 2x + 3y = 12 Yes, this is in Standard Form. It follows all of the rules.

D. 5x + 5y = 10 Yes, this is in Standard Form. It follows all of the rules.

So, C and D are both written in Standard Form.

The manager of the Danvers-Hilton Resort Hotel stated that the mean guest bill for a weekendis $600 or less. Amember of the hote

alexdok [17]

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.

Which equation represents a direct variation?

8090 [49]

Answer:

Y = x y = kx. When the equation that describes direct variance is graphed in the Cartesian Plane, there is always a straight line moving through the origin. Think of it as the Slope-Intercept Shape of a line written as y = mx + b y = mx + b.
