Step-by-step explanation:
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
Answers
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

1. Which size bag of cat food shown in the table has the lowest unit price?
Size (oz) Cost ($)
24
5.49
40
8.00
64
15.99
Answers
Answer:
The one that costs $15.99
Step-by-step explanation:
Divide 24/5.49=4 and something cents
Then 40/8 to get $5
Then 64/15.99 to get $4.00
The lowest price is $0.20 the size 40 oz bag cost $8.00 showing the lowest unit price.
What is a fraction?Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
We have:
24 oz bag cost $5.49
Cost of 1 oz cat food = 5.49/24 = $0.228
40 oz bag cost $8.00
Cost of 1 oz cat food = 8/40 = $0.2
64 oz bag cost $15.99
Cost of 1 oz cat food = 15.99/64 = 0.2498
Thus, the lowest price is $0.20 the size 40 oz bag cost $8.00 shows the lowest unit price.

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.

Find the x - and y-intercepts of the graph of the linear equation 2x + 3y = 12.
The x-intercept is
The y-intercept is
Answers
Answer:
Y intercept = (0,4)
X intercept = (6,0)
Step-by-step explanation:
First you need to make the equation slope intercept form.2x+3y=12
To do so, you need to get y on it's own (or on one side)
Subtract 3y from the left side.-3y+12=2x
Then, divide everything out by -3y-4=-2/3x
Add four to the other sidey= -2/3x +4
-2/3x= slope while 4= y intercept
You can also graph it on desmos and find the y intercept and x intercept
We want to find the x and y-intercepts of a given equation.
The solution is:
The x-intercept is x = 6 The y-intercept is y = 4First, we start by defining what x-intercept and y-intercept are.
The x-intercept is the x-value at which the graph of the equation intercepts the x-axis, and is equivalent for the y-intercept.
So, for a given function y = f(x).
We define the y-intercept as the value of y when we define x = 0.
And we define the x-intercept as the value (or values) of x when y = 0.
Here we have:
2x + 3y = 12
So to get the x-intercept, we just need to define y = 0 and solve for x.
2x + 3*0 = 12
2x = 12
x = 12/2 = 6
To get the y-intercept, we just need to define x = 0 and solve for y.
2*0 + 3*y = 12
3*y = 12
y = 12/3 = 4
Then we can conclude:
The x-intercept is x = 6 The y-intercept is y = 4If you want to learn more, you can read:

-6•f(-3) - 5.g(-7) =
Answers
Ah, function problems, I had this in my math class around 2-3 weeks ago. So f and g is the function here.
TO SOLVE:
Simply look at where each plot is at. f(-3) is at (0, -3). So we will substitute -3 into f(-3).
Now, our equation should look like:
-6•(-3)-5•g(-7).
We can now take a look at the function, g. We can see that g(-7) lays at (-7, 6). We only need the Y here so it will be 6. Now, plug it in:
-6•(-3)-5•6=
=18-30
=-12
So thus, -12 is the answer!

-10 - 12v + 48 = -82
-12v + 38 = -82
-12v = -120
v = 10
hope this helped, if you need a more in depth answer to how i did it just ask
Answer:
Hello! I hope I’m correct! :)
Step-by-step explanation:
The answer should be V = 10
First, Add 10 to both sides.
-6(2v-8) = -82+10
Next, Simplify
-6(2v-8) = -72
Than, divide both sides by -6
= -72/-6
{Note: two negatives makes a positive}
= 72/6
Simplify.
2v-8=12
Add (+) 8 to both of the sides.
2v= 12+8
Simplify 12+8 to...
2v = 20
Now, divide both sides by 2
V = 20/2
Since we have 20/2, we need to simplify (divide 20 & 2)
20 divided by 2 = 10
V = 10
Therefore the answer is v = 10Hope this helps! If you have any questions about these steps, feel free to ask! Have a nice day! :)
