Answer: If he has 3 mystery books, and those are 1/8 of his whole collection, he has 24 books.

Step-by-step explanation:

3 = 1/8 × x

multiply both sides by the reciprocal of 1/8 which is 8/1 ("flipped fraction")

8 × 3 = 8/1(1/8) x When you multiply a fraction by its reciprocal, it produces 1, so it "cancels" in the multiplication

24 = x 

This may seem complicated, but understanding the process will help you solve more complicated questions like this in the future, I hope.

Len [333]

Answer:

Standard deviation of the length of granola bars produced at Bernie's Bars is 0.50

Step-by-step explanation:

We are given the following information in the question:

Formula:

$z_{score} = \displaystyle\frac{x - \mu}{\sigma}$

where,

μ is the mean and σ is the standard deviation.

Putting the values we get:

$\displaystyle\frac{ 3- \mu}{\sigma} = 1\\\\3 = \sigma + \mu\\\\\displaystyle\frac{ 3.5- \mu}{\sigma} = 2\\\\3.5 = 2\sigma + \mu$

Solving the two obtained equations:

Subtracting the two obtained equation, we have:

$3.5-3 = \mu + 2\sigma - \mu -\sigma\\\sigma = 0.5$

Hence, standard deviation of the length of granola bars produced at Bernie's Bars is 0.50
