You'll have three copies of the red "-x" rectangles to represent -3x
Next, you'll need five copies of the blue squares with the label "1". This represents 5 since 1*5 = 5.
Lastly, you'll need one copy of the purple rectangle that has "y" on it.
All of this forms the expression -3x+5+y
All of these figures will be above the dashed line to be in the positive region.

A researcher surveys job satisfaction among laborers and white-collar workers. (Job satisfaction is rated on a scale from 1 = low satisfaction to 10 = high satisfaction.) Results show that laborers have a mean job satisfaction score of 3 and a SD 1; white-collar workers have a mean job satisfaction rating of 7 and a SD of 3.16. Which statement is the best interpretation of the mean and SD?
A. Laborers are less satisfied than white collar workers and most laborers are about equally dissatisfied, while there is more variation in the satisfaction of white collar workers
B. Laborers generally are less satisfied than white-cofar workers, but laborers wojtas kely to be highly satisfied as white collar workers are to be highly satisfied
C. White-colar workers and laborers we bout equally waited but there is more variation among white collar workers
D. White collar workers are more satisfied than laborers, but have similar amount of variation
Answer:
Option A is the answer
Step-by-step explanation:
From the question we are told that
The mean of laborers is 3
The standard deviation is 1
The mean of white collar workers is 7
The standard deviation for white collar workers is 3.16
From this value given we can see that the white collar worker is more dissatisfied than the laborers
Also the from the value of standard deviation of the laborers we see that the deviation from the mean is 1 which means that they are equally dissatisfied
But in the case of white collar workers we see deviation from the mean is very high which implies that the dissatisfaction varies more with white collar workers
If x = 4 and y = 7, evaluate the following expression:
20 – (3y – 4x)
Answer:
15
Step-by-step explanation:
x=4, y=7
20-(3y-4x) Substitute the values for the variables:
20-(3*7-4*4) Multiply:
20-(21-16) Parentheses first:
20-5
=15
Hope this helps :)
The solution for the expression 20 – (3y – 4x) will be 15.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the values are x = 4 and y = 7, the expression will be solved as below,
E = 20-(3y-4x)
Substitute the values for the variables:
E = 20-(3 x 7-4 x 4) Multiply:
E = 20-(21-16) Parentheses first:-
E = 20-5
E = 15

A certain academic department at a local university will conduct a research project. The department will need to hire graduate research assistants and professional researchers. Each graduate research assistant will need to work 30 hours per week on fieldwork and 10 hours per week at the university's research center. Each professional researcher will need to work 12 hours per week on fieldwork and 28 hours per week at the university's research center. The minimum number of hours needed per week for fieldwork is 163 and the minimum number of hours needed per week at the research center is 131. Each research assistant will be paid $246 per week and each professional researcher will be paid $407 per week. Let x denote the number of graduate research assistants hired and let y denote the number of professional researcher hired. The department wants to minimize cost. Set up the Linear Programming Problem for this situation.a) Min C = 246x + 407y; s.t 30x + 12y ≥ 163, 10x + 28y ≥ 131, x ≥ 0, y ≥ 0b) Min C = 246x + 407y; s.t 12x + 30y ≤ 131, 28x + 10y ≤ 163, x ≥ 0, y ≥ 0c) Min C = 246x + 407y; s.t 30x + 12y ≥ 163, 28x + 10y ≥ 131, x ≥ 0, y ≥ 0d) Min C = 407x + 246y; s.t 30x + 10y ≥ 163, 12x + 28y ≥ 131, x ≥ 0, y ≥ 0e) Min C = 407x + 246y; s.t 12x + 30y ≥ 163, 28x + 10y ≥ 131, x ≥ 0, y ≥ 0f) None of the above.
Answer:
The answer is "Option a".
Step-by-step explanation:
In the question, Option a is correct, because in this choice, Let x determine its amount of pupils hired and the point y is let as it's mean that it is the number of experts who recruited in the researcher, and description of the choice can be defined as follows:
[tex]Min C = 246x + 407y; \\\\s.t \ 30 x + 12 y \geq 163, \\\\10x + 28y \geq 131, \\\\x \geq 0, \\\\y \leq 0\\\\[/tex]
Square roots can be compared and ordered by comparing and ordering the numbers underneath the radical symbol.

Answer:
No solution
Step-by-step explanation:
4(x-8) = 4x-8
Distribute.
4x-32 = 4x-8
Subtract 4x first and get rid of the variable (x).
4x-32 = 4x-8
-4x -4x
-32 = -8
-32 does not equal -8, so there is no solution!
