Answer:
Number of items sold, discrete; time spent at desk, continuous
Step-by-step explanation:
The random variables from the survey is number of items sold, discrete; time spent at desk, continuous
What is random selection ?A selection that is chosen randomly (purely by chance, with no predictability). Every member of the population being studied should have an equal chance of being selected.
According to the question
The supervisor at an office randomly selected 45 employees and observed their work habits.
She recorded
i > number of items sold
ii > total time the employees spent at their desk
As per observation
Number of items sold = discrete
as it is not possible to sell items in a continuous manner
But
time spent at desk = continuous
as every employee spend time at there desk
Hence, the random variables from the survey is number of items sold, discrete; time spent at desk, continuous

W 3 Aisha has $100 saved from her job. She wants to buy as many charms for her bracelet, at $4 each and earrings at $5 per set, as she can without spending all of her money. The inequality represents her spending, where x is the number of charms and y is the number of sets of earrings. 4x + 5y < 100
Simplifying 4x + 5y < 100 Solving 4x + 5 < 100. Solving for variable 'x' move all terms containing x to the left, all other terms to the right.

Read this entry from a blog about service dogs. Lexie, an eight-month-old black Labrador retriever, is sleeping quietly at my feet. I can’t help but think that her soft, velvety ears and alert brown eyes would make her the perfect "doggie model" for pet magazines and pet store ads. However, Lexie will soon have a much more important job to do. In a few months, she will become the loyal companion and service dog for a young man who has been blind since birth. She will help him board public transportation, such as buses, subways, and trains, and she will help him safely cross busy intersections. Lexie will even help the young man avoid obstacles, such as high curbs and low overhangs. Like all dogs in our organization, Lexie has undergone months of specialized training to help a visually impaired person lead an active and independent life. Which statement about this blog is true? Its primary purpose is to persuade; its secondary purpose is to inform. Its primary purpose is to inform
Answer:
The True Statement about this blog is stated below:
Its primary purpose is to inform.
Step-by-step explanation:
When an author's or speaker's purpose is to inform, the author or speaker usually enlightens their readers or audience about real-world topics. The best way they achieve this is by providing lots of facts about the topic. Informational texts or speeches are oriented towards imparting information or knowledge to the reader or audience with the purpose of educating them on a particular topic. This is clearly achieved in this passage about Lexie. Facts are provided about Lexie's ability to help the visually impaired person, including the specialized training that the dog has undergone recently.

Part A
Katie just opened a checking account at the bank. Within the first month, she deposited three checks for $21.68, $42.09, and $65.44. She withdrew $4.64 for new pencils, $23.11 for earbuds, and $9.78 for movies from her account in the same month.
Write Katie’s withdrawals as negative rational numbers and her deposits as positive rational numbers.
Part B
Order the rational numbers from least to greatest and explain your reasoning.
Part C
At the beginning of the month Katie’s balance was $128. What was her balance at the end of the month after all of her deposits and withdrawals? You must show your work, no credit will be given for just an answer.
Answer:
(a) The deposits to be 21.68, 42.09, and 65.44 and the withdrawals to be -4.64, -23.11 and -9.78
(b) [tex]Order: -23.11, -9.78, -4.64, 21.68, 42.09, 65.44[/tex]
(c) [tex]Final\ Balance = \$219.68[/tex]
Step-by-step explanation:
Given
Deposits: $21.68, $42.09, and $65.44
Withdrawals: $4.64, $23.11 and $9.78
Solving (a): Write out the deposits as positive and the withdrawals as negatives
From (given) above, we have
The deposits to be 21.68, 42.09, and 65.44
and
The withdrawals to be -4.64, -23.11 and -9.78
Solving (b): Order from least to greatest.
Since the withdrawals are negative, the arrangement will start from there because negative numbers are lesser than positives.
Arranging the withdrawals from least to greatest, we have:
-23.11, -9.78, -4.64.
Arranging the deposits from least to greatest, we have:
21.68, 42.09, 65.44
Combine both together;
[tex]Order: -23.11, -9.78, -4.64, 21.68, 42.09, 65.44[/tex]
Solving (c):
[tex]Initial\ Balance = \$128[/tex]
Required
Determine the final balance
First we need to get the total deposits:
[tex]Total\ Deposits = \$21.68 + \$42.09 + \$65.44[/tex]
[tex]Total\ Deposits = \$129.21[/tex]
Next, we determine the total withdrawals:
[tex]Total\ Withdrawals = \$4.64 + \$23.11 + \$9.78[/tex]
[tex]Total\ Withdrawals = \$37.53[/tex]
The final balance is then calculated as:
[tex]Final\ Balance = Initial\ Balance + Total\ Deposits - Total\ Withdrawals[/tex]
[tex]Final\ Balance = \$128 + \$129.21 - \$37.53[/tex]
[tex]Final\ Balance = \$219.68[/tex]
Translate this sentence into an equation.
28 is the product of Rhonda's age and 2.
Use the variable r to represent Rhonda's age.
The sentence "28 is the product of Rhonda's age and 2" can be translated into the following equation as 28 = 2 × r
In this equation, use the variable 'r' to represent Rhonda's age.
The equation states that the number 28 is equal to the product of 2 and Rhonda's age (r).
This equation describes the relationship between the value 28 and Rhonda's age.
If you know the value of 'r', you can solve for 28, and vice versa.
It's a simple way to express the given information mathematically.
Therefore, the given sentence about product of Rhonda's age and 2 is equal to 28 written in the equation form as 28 = 2 × r .

The simplest form of 2/5 divided by 4 is 1/10.
What is a fraction?A fraction is a part of a whole.
It is expressed as a quotient, in which the numerator is divided by the denominator.
Example: 2/3, 5/7, 1/3
We have,
2/5 ÷ 4
= (2/5) / 4
= 2 / (4 x 5 )
We cancel the common factor from the numerator and denominator.
= 2 / (2 x 2 x 5)
= 1 / (2 x 5)
= 1 / 10
We see that there is no common factor to be canceled out from the numerator and the denominator.
= 1/ 10 is our simplest form.
Thus the simplest form of 2/5 divided by 4 is 1/10.
