A juice drink filling machine, when in perfect adjustment, fills the bottles with 12 ounces of drink on an average. Any overfill

ozzi

Answer:

d. The average is equal to 12 ounces.

Step-by-step explanation:

In this problem, the drink filling machine must be perfectly calibrated at 12 ounces since it needs to be shut down in cases of overfilling (mean > 12 ounces) and underfilling (mean < 12 ounces). Therefore, the correct approach would be to test if the mean is 12 ounces and the correct set of hypothesis would be:

$H_0:\mu=12\\H_a:\mu\neq 12$

The correct alternative is d. The average is equal to 12 ounces.

What is the area of the circle to the nearest square foot if the circumference is 40?

Hunter-Best [27]

Answer:
127 square ft

Explanation:
The formula to find the area of a circle with a know circumference is: C^2/4 π.

40^2 is 1600 and 4 times pi is 12.56. Divide 1600 by the 12.56 and you will get your area of 127.39. The answer is 127 square ft after rounding to the nearest square foot.
