Question:

For a population with a mean of μ=45 and a standard deviation of σ=10. What is the corresponding z score if it has a score of X = 44?

Answer:

[tex]z = -0.10[/tex]

Explanation:

Given

[tex]\mu = 45[/tex]

[tex]\sigma = 10[/tex]

[tex]x = 44[/tex]

Required

Calculate the z score

This is calculated as:

[tex]z = \frac{x - \mu}{\sigma}[/tex]

So:

[tex]z = \frac{44 - 45}{10}[/tex]

[tex]z = \frac{-1}{10}[/tex]

[tex]z = -0.10[/tex]

Smell: Spring brings soothing scents like lilacs, apple blossoms, hyacinth and daffodils. Sweet aromas turn a stroll through the garden into a delicacy for the nose Springtime means that the trees and flowers come back to life again. After a dead winter, this is a time when we get to see the beautiful flowers blossom again Spring also brings new sounds, like bird songs at dawn, frog croaks by ponds, and dripping icicles. When the weather warms, the sounds you hear in national parks reflect this seasonal change (use this but not in this order fix it up a bit)

B. Reflection over the x axis, dilation with a scale factor of 1/2

When you get a question like this, choose the option that includes “dilation.” Dilation changes the size of the shape while keeping similarity.

Read Chapter One of the story The Mystery of the Missing Library Books:Chapter One: A New CaseA growing mass of clouds blocked the sun, just as I, Dennis the Detective, entered the library. When I requested the new book about my hero, Sherlock Holmes, the library helper's brow furrowed, and his tense lips formed a line like a ruler."I'm afraid that book is no longer available," Victor stated.I stared in disbelief. Turning, I walked towards the new releases section, but most of the shelves were as empty as overturned buckets. Sandra, my sidekick, was hidden behind her pile of books. She updated me on detective gear, handed me a glass of water, and introduced our next assignment. We would be investigating the missing library books. I looked at Sandra, reluctant to investigate books.Just then, Victor pulled up a chair and sat down. Sandra introduced him to me as our client. Victor adjusted his glasses, looked down at the ground, and took a deep breath. He explained that library books were disappearing each night, especially new releases. The only people who had keys were the librarians and the library helpers. The librarians were beginning to blame the library helpers for the missing books, thinking that they weren't locking the library doors properly. This obviously didn't sit well with Victor, and one librarian in particular had him worried. Wilma always stayed until the last minute and left without checking anything out. The next day, the books were gone.I raised my eyebrows and rubbed my hands together in anticipation. I had misjudged the situation, thinking it would be easy. Instead, this puzzle would require all of my detective skills.Why were Wilma's actions suspicious? (2 points) aWilma didn't check any of the books out because she was at the library every day. bWilma had to be taking the books and blaming the library helpers to cover up. cWilma never took any books out because she had big fines on her library card. dWilma stayed late and left without checking out books, so she could be taking them. 3.
