Ajuice drink filling machine, when in perfect adjustment, fills the bottles with 12 ounces of drink on an average. any overfilling or underfilling results in the shutdown and readjustment of the machine. to determine whether or not the machine is properly adjusted, the correct alternative hypotheses is
a. the average is greater than or equal to 12 ounces.
b. the average is not equal to 12 ounces.
c. the average is less than 12 ounces.
d. the average is equal to 12 ounces.

b. the average is not equal to 12 ounces.

Step-by-step explanation:

a and is incorrect because being equal to 12 ounces is what we want.

c  - we want to look for greater than 12 as well as less than.

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
