Answer:
Step-by-step explanation:
Hey there!
I think that some of the content in your question is missing so I will be solving for how much yards of fabric is needed in total
Since all of the fractions have common denominators, we can comfortably add them together
3/4+3/4+2/4 is 8/4
8/4 can be simplied to 2
So the total amount of yards of fabric Thom needs in total is 2 yards
The percentage of the snakes is longer than 16.6 in. with a mean of 15 in. and a standard deviation of 0.8 in. is 2.275%.
<h3>What is a normal distribution?</h3>
It is also called the Gaussian Distribution. It is the most important continuous probability distribution. The curve looks like a bell, so it is also called a bell curve.
The z-score is a numerical measurement used in statistics of the value's relationship to the mean of a group of values, measured in terms of standards from the mean.
The lengths of a particular snake are approximately normally distributed with a given mean = 15 in. and standard deviation = 0.8 in.
Then the percentage of the snakes is longer than 16.6 in. will be

Then we have

Answer:
1 ornament per 3 hours
in 15 hours she will have 7.5 of them done
She bought 15 packages. You divide 86 by 6, but there is a remainder. pay no attention to it though, just add 1 to the answer.
