Answer:
Correct: A, B, C, E, AND F
Step-by-step explanation:
The reason being, that the larger the negative number, the smaller it gets. Think of it like this:
One person owes another, 8 dollars, and let's say he currently has none. So if he owes 8 dollars and he has none, then it would be 0-8, or, -8.
Now let's say someone else owes 200 dollars, and they have 100 dollars.
If they give 100 dollars, they still need to give another 100, right? so it would be -100 dollars, therefore, a greater debt than the guy with the 8 dollars.
If a negative number looks larger than another, in reality, it's just a bigger debt to pay, so it's smaller worth. -8 is larger than -100 because it's closer to 0.
Last example:
-100, -75, -50, -30, -23, -8, -2, 0, 1, 2, 3... See? -8 is closer to zero than -100, so it's larger.
C is correct because negatives are smaller than positives. -1 is below 0, so it's smaller than 1, which is greater than 0.
Hope this helps :)

Each week, the Pickering Trucking Company randomly selects one of its 30 employees to take a drug test. Write an application that determines which employee will be selected each week for the next 52 weeks. Use the Math.random() function explained in Appendix D to generate an employee number between 1 and 30; you use a statement similar to:
Answer:
In Java:
import java.util.Random;
public class Main{
public static void main(String args []){
int Employee;
for(int weeks = 1;weeks<=52;weeks++){
Employee = 1 + (int)(Math.random() * 30);
System.out.println("Week "+weeks+" selected employee: "+Employee);
}
}
}
Step-by-step explanation:
This imports the Random package into the program
import java.util.Random;
public class Main{
public static void main(String args []){
Declare employee as integer (represents employee 1 to 30)
int Employee;
Iterate from week 1 to 52
for(int weeks = 1;weeks<=52;weeks++){
Randomly select an employee from 1 to 30 (inclusive)
Employee = 1 + (int)(Math.random() * 30);
Print the selected employee
System.out.println("Week "+weeks+" selected employee: "+Employee);
}
}
}

Actually Welcome to the concept of Parallel lines.
We must first understand that, Parallel Lines always have a same Slope, hence the 'm' value in y=mx+c equation will same, here it is '1/2' in the above equation,
so the points here are (-6,-17)
==>
(y-(-17)) = m(x-(-6))
==>
here m = 1/2 ,hence
y+17 = 1/2(x+6)
==> y+17 = 1/2(x) + 3
==> y = 1/2(x) + 3 - 17
==> y = 1/2(x) - 14
hence the Option 4.) is the correct answer!!

Drag the expressions into the order in which the expressions are listed from greatest value to least value. Place the expression with the greatest value at the top and the one with the least value at the bottom.
(5280×10)−(314×10)
5280−314
10.6× (5280 −314)
(5280−314)÷111
Step-by-step explanation:
I did the test!Greatest expression=10.6× (5280 −314)
Least expression= (5280−314)÷111
Step-by-step explanation:Definition of greatest value and least valueThe greatest value is the maximum value in given observation and least value is the minimum value in the given observation.
Solution of first expression
[tex](5280*10)-(314*10)= 52800-3140\\=49660[/tex]
Solution of second expression

Answer:
area = 220.5 ft²
Step-by-step explanation:
2(Length) + 2(10.5) = 63 feet
2L + 21 = 63
subtract 21 from each side of the equation:
2L = 42
divide both sides by 2:
L = 21 feet
area = L x W = 21 x 10.5 = 220.5 ft²
Answer:
A = 220.5 ft
Step-by-step explanation:
[tex]2(Length) + 2(10.5) = 63 feet\\[/tex]

$600 invested at 5% compounded daily after a period of 3 years.
Answer:
$697.09
Step-by-step explanation:
The computation of the investment after 3 years is shown below:

Amount = Present value × (1 + rate)^number of years
= $600 × (1 + 0.05 ÷ 365)^365× 3
= $697.09
Hence, the investment after 3 years is $697.09
