18^4 this is another way to show an exponent
Answer:
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:
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:
Answer they are all equivalent
Step-by-step explanation:
Answer:
9x + 6
Step-by-step explanation:
<u>Step 1: Distribute</u>
5x + (x + 6) + 3x
5x + x + 6 + 3x
<u>Step 2: Combine like terms</u>
5x + x + 6 + 3x
9x + 6
Answer: 9x + 6
Asumming that 3/5 is the number of miles Jennifer has gone in 1/5 of an hour. We can take 60 (# of minutes in an hour) divided by 5, which equals 12. So 3/5 is 36 minutes. to figure out how many 1/5 are in 8 miles we would take 8 times 5 which is 40. We would then take 3 times 8, which is 24. 40 - 24 = 16. So 16 times 5 = 80 minutes. 80 divided by 60 (# of minutes in an hour) is 1 hour and 20 minutes. So it takes Jennifer 1 hour and 20 minutes to travel 8 miles.
