C. An even number plus 3 is always odd.
Prime number: A number that can only be divided by 1 and itself. For example 7, 11, etc
Odd number: Any number that cannot be divided by 2. For example 3, 5, 7, etc
Even number: Any number than can be divided by 2. For example: 4, 6, 8, etc
If we add 2,4,6 or 1000 to 3, the resultant will be always odd. If we add 2 to 3, we will get 5 which is an odd number. If we add 8 to 3, you will get 11 which is an odd number.
So, the conjecture is :
An even number plus 3 is always odd.
Therefore the correct option is (c).

A flower bed has the shape of a rectangle 21 feet long and 9 feet wide. What is its area in square yards?
Answer:
21 square yards
Step-by-step explanation:
Let's remember that the formula of the area of a rectangle is A = L*W, where L is the length and W the width.
In this case, L = 21 feet and W = 9 feet.
Therefore, A = 21 feet * 9 feet = 189 square feet
We need the answer in square yards. We know that 1 feet equals 1/3 yard (1 feet = 1/3 yard)
As we need square yards, we just square the equation above.
1^2 square feet = (1/3) ^2 square yards
1 square feet = 1/9 square yards
The area is 189 square feet, so we just multiply by 189 on both sides to do the conversion to square yards.
189 square feet = 189*1/9 square yards
189 square feet = 21 square yards
The area of the flower bed is 21 square yards

a minor league baseball team plays 114 games in a season. if the team won 14 more than three times as many games as they lost, how many wins and losses did the team have?
To solve this problem, we can set up an equation. Let L be the number of games lost by the team. We are told that the team won 14 more than three times the number of games they lost, so the number of games won is 3L + 14. The team lost 25 games and won 89 games.
Explanation:To solve this problem, we can set up an equation. Let L be the number of games lost by the team. We are told that the team won 14 more than three times the number of games they lost, so the number of games won is 3L + 14.
The total number of games played is the sum of the games won and the games lost, which is 114. So we have the equation:
(3L + 14) + L = 114
Simplifying the equation, we get:
4L + 14 = 114
Subtracting 14 from both sides, we have:
4L = 100
Dividing both sides by 4, we find that L = 25.
Therefore, the team lost 25 games. To find the number of wins, we can substitute the value of L into the equation we set up earlier:
3L + 14 = 3(25) + 14 = 75 + 14 = 89.
So the team had 89 wins and 25 losses.

Two points on a line are (3,8) and (-3,2). What is the slope of the line
The slope of the line passing through the points (3,8) and (-3,2) is 1
The slope of the line passing through the points (x₁, y₁) and (x₂, y₂) is given by the formula:
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
where m represents the slope
For the line passing through the points (3,8) and (-3,2).
x₁ = 3, y₁ = 8, x₂ = -3, y₂ = 2
Substitute x₁ = 3, y₁ = 8, x₂ = -3, y₂ = 2 into the slope formula above
[tex]m = \frac{2-8}{-3-3}\\\\m = \frac{-6}{-6} \\\\m = 1[/tex]
Therefore, the slope of the line passing through the points (3,8) and (-3,2) is 1

Marlow is comparing the prices of two truck rental companies. Company A charges $3 per hour and an additional $75 as service charges. Company B charges $2 per hour and an additional $85 as service charges. Part A: Write an equation to represent each company's total charges for renting a truck for a certain number of hours. For both equations (one for Company A and one for Company B), define the variable used. (4 points) Part B: Which company would charge less for renting a truck for 5 hours? Justify your answer. (3 points) Part C: How much money is saved by using the services of Company A instead of Company B to rent a truck for 3 hours
Answer:
A)
Company A) would be y = 3x + 75
Company B) would be y = 2x + 85
company A company B
A = 3(5) + 75 B = 2(5) + 85
A = 15 + 75 B = 10 + 85
A = 90 B = 95
B)
Company A) so that would give us y = $90
Company B) and this would give us y = $95
C)
Company A- in 3 hours you would spend $84
Company B- in 3 hours you would spend $91
so you save $7 by using A instead of B

Why is indirect compensation important to recruiting and retaining employees? (site 1)
Indirect compensations may encompass sales commisons, health, transport, accommodation allowances and so on which aren't included as part of their base salary.
Indirect compensations go a long way assisting employees in different aspects of their personal lives which may not be directly related to work.
A good indirect compensation which caters for transport, housing and medical expenditures seems way more beneficial than a huge base salary without allowances.
Also, indirect allowances such as commission encourages employees to put more effort into sales and marketing since it is based on percentage. Hence, the more they input, the more their earning.
Therefore, indirect allowances are of considerable benefit which is highly considered when choosing an employer.

What is unit conversion?In order to translate measurements of a particular amount between different units, a mathematical conversion factor is usually used. This modifies the measurement of the quantity without altering its effects.
The particular circumstances or the intended result control the conversion process. This may be governed by law, a contract, a list of technical specifications, or other publicly available standards.
A precise conversion from one system to another is necessary for some measures in order to maintain the precision of both the original measurement and the conversion.
Based on the connection between a particular pair of original units and a particular pair of target units, each conversion factor is chosen.
Given data ,
Let the weight of the stone be = 4 ounces
And , let the weight of the collection be = 24 pounds
From the unit conversion , we get
1 pound = 16 ounces
So , 24 pounds = 16 x 24 = 384 ounces
And , the number of stones A = 384 ounces / weight of the stone
On simplifying , we get
The number of stones A = 384 / 4 = 96 stones
Hence , the number of stones is 96
