A company claims that its soup vending machines deliver exactly 8 ounces of soup to every customer. You do not want the vending

lorasvet [3.4K]

Answer:

$H_0: \mu = 8$

$H_1: \mu \neq 8$

Step-by-step explanation:

A company claims that its soup vending machines deliver exactly 8 ounces of soup to every customer.

This means that the null hypothesis is that the mean is exactly 8, that is:

$H_0: \mu = 8$

You do not want the vending machines to deliver too much or too little soup.

We don't want the mean to be different from 8, which means that the alternative hypothesis is given by:

$H_1: \mu \neq 8$

The graph of y = f(x) is graphed below. Wat is the end behavior of f(x)? <br> PLEASE ASAP

Maurinko [17]

Answer:

B.) as x --> -∞, f(x) --> ∞ and x --> ∞, f(x) --> ∞

Step-by-step explanation:

F(x) is another way of representing "y". That being said, the question is asking you the behavior of the graph in terms of the y-axis. On both sides of the function, there is an arrow pointing upwards, towards infinite, positive y-values. Therefore, as "x" approaches -∞ and ∞, f(x) is approaching ∞ (positive infinity).
