Answers:
<span>B) The store loses money when 20 or more clerks are working.
</span><span>E) Maximum profits are earned when there are 10 clerks working.
</span>
Explanation:
Let's check each of the given choices:
Choice A:
The maximum profit occurs at the peak of the parabola given. Reading the graph, we can find that the maximum profit is about 18,000.
Therefore, this choice is not correct
Choice B:
The x-axis represents the number of clerks. We can note that for 20 or more, the value of the profit is decreasing. This means that the store is losing money.
Therefore, this choice is correct
Choice C:
To know whether the store earns profit when no clerks are working or not, we will need to read the value of the y-axis (profit) when the x-axis (clerks) is zero. Doing this, we will find that no profit is earned when no clerks are working.
Therefore, this choice is not correct
Choice D:
Maximum profit occurs at the peak of the parabola given. Therefore, to know the number of clerks corresponding to the maximum profit, we will need to read the x-value of the peak of the parabola. Doing this, we will find that maximum profit occurs when the number of clerks is 10.
Therefore, this choice is not correct.
Choice E:
Maximum profit occurs at the peak of the parabola given. Therefore, to know the number of clerks corresponding to the maximum profit, we will need to read the x-value of the peak of the parabola. Doing this, we will find that maximum profit occurs when the number of clerks is 10.
Therefore, this choice is correct

Answer:18
Step-by-step explanation:
Sin72=cosy
0.9511=cosy
Y=cos(inverse)0.9511
Y=18
Answer:
y=1/2x
Step-by-step explanation:
Slope intercept form is the most commonly used linear equation:
It goes like this:
In this equation, m is the slope and b is the y-intercept.
Your line has a slope of 1/2. So, your m-value is 1/2.
y=1/2x+b
B, your y-intercept, is at the origin.
The origin is the point (0,0).
So b, is 0 (y-intercept is the y-value when x is 0)
y=1/2x+0
=
y=1/2x
Hello!
You can use the equation to find the volume of a rectangular prism which is
V = whl
V is volume
w is width
h is height
l is length
1 1/2 = 1.5
Put in the values you know
120 = w * 8 * 1.5
Now you solve it algebraically
Divide both sides by 8
15 = w * 1.5
Divide both sides by 1.5
10 = w
The answer is 10 inches
Hope this helps!
Association between the variables shown is a linear association.
<h3>What is a scatter plot?</h3>
A scatter plot is a graph that shows the association between variables. The association is linear if it can be fitted into a straight line. The equation of a straight line is given by y = mx + c.
We can see from the scatter plot that the association between the variables shown is a linear association.
