Answer:

18

Step-by-step explanation:

So lets go voer what we know:

There are 6 pieces of ribbon.

Each piece of ribbon is 1 yard long.

We need 1/3 of each ribbon(1/3 yard).

To find this, lets take our 6 pieces of ribbbon, and break them into 3 seperate pieces.

This is because we need ribbons that are 1/3 of a yard. 3 ribbons would make up a single yard.

So:

The 6 yards of ribbon x 3 ribbons that make up 1 yard

6*3

=

18

I hope this makes more sense, and helps you understand better. I can try to explain in a different way if this still doesn't make sense.

I hope this helps! :)

Answer:

It’s D, 18 cuts

Step-by-step explanation:

She cut a 6 yard long ribbon into 1/3 yard pieces so you would have to divide to get the answer and the steps to dividing is

Stay the same, change the sign, flip it
so the 6 would stay the same, you would change the division sign to multiplication because division is the opposite of multiplication, and you would flip the 1/3 into 3/1 so

6 x 3/1 would be 18/1 which is just 18

A researcher is 95% confident that the interval from 5.2 hours to 7.8 hours captures u = the true mean amount of time
igor_vitrenko [27]
<h3>Answer: Choice B</h3>

No, this is not a plausible value for the population mean, because 5 is not within the 95% confidence interval.

====================================================

Explanation:

The greek letter mu is the population mean. It has the symbol \mu which looks like the letter 'u' but with a tail at the front or left side.

The question is asking if mu = 5 is plausible if the researcher found the 95% confidence interval to be 5.2 < mu < 7.8

We see that 5 is <u>not</u> in that interval. It's a bit to the left of 5.2

Since mu = 5 is not in the interval, it's not a plausible value for the population mean.

Have we ruled it out with 100% confidence? No. Such a thing is not possible. There's always room for (slight) error. The researcher would need to do a census to be fully confident; however, such practices are very time consuming and expensive. This is the main reason why statistics is important to try to estimate the population with a sample.
