At the 25,000 salary scale, the options yield will be the same salary the answer is 25,000.
What is percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
We have:
Your employer offers you a choice of wage scales:
A monthly salary of $2800 plus a commission of 8% of sales or
A salary of $3300 plus a 6% commission.
First choice of wage scale:
= 2800 + 0.08s
Second choice of wage scale:
= 3300 + 0.06s
2800 + 0.08s = 3300 + 0.06s
0.08s - 0.06s = 3300 - 2800
0.02s = 500
s = 25,000
Thus, at the 25,000 salary scale, the options yield will be the same salary the answer is 25,000.

F(x) = 9 sin(x) + cot(x), −π ≤ x ≤ π find the interval of increase.
Final answer:
To find the interval of increase for the function F(x) = 9*sin(x) + cot(x), we need to find where the derivative is positive. The interval of increase for the function is (0, π/2) and (π, 3π/2).
Explanation:
In order to find the interval of increase for the function F(x) = 9*sin(x) + cot(x), we need to find where the derivative is positive. Let's first find the derivative of F(x). The derivative of sin(x) is cos(x) and the derivative of cot(x) is -csc^2(x).
So, the derivative of F(x) is 9*cos(x) - csc^2(x). Now, to find where the derivative is positive, we need to find the intervals where 9*cos(x) - csc^2(x) > 0. We can solve this inequality by analyzing the sign changes of the derivative function.
By analyzing the sign changes of 9*cos(x) - csc^2(x), we find that the derivative is positive when x is in the intervals (0, π/2) and (π, 3π/2). Therefore, the interval of increase for the function F(x) = 9*sin(x) + cot(x) is (0, π/2) and (π, 3π/2).
There are 375 books sold at Sid's Bookstore. The table below summarizes these books by genre. This info is presented in circle graph. Find the central angle measure for Self Help slice in graph. Mystery 99, romance 81, self help 90, cooking 57, biography 48.
The central angle measure for the 'Self Help' slice in the circle graph is 86.4 degrees.
To find the central angle of the 'Self Help' slice in a circle graph (pie chart), we first need to calculate the total number of books sold, which is provided as 375.
We then take the number of 'Self Help' books which is 90, and determine what fraction of the total this represents. The fraction for 'Self Help' books is 90/375. A full circle has an angle of 360 degrees, so we multiply the fraction by 360 to find the central angle for that section of the pie chart.
= (90/375) * 360 = 0.24 * 360 = 86.4 degrees
Thus, the central angle measure for the 'Self Help' slice in the graph is 86.4 degrees.

Suppose f⃗ (x,y,z)=⟨x,y,4z⟩f→(x,y,z)=⟨x,y,4z⟩. let w be the solid bounded by the paraboloid z=x2+y 2 z=x2+y2 and the plane z=9.z=9. let ss be the closed boundary of ww oriented outward. (a) use the divergence theorem to find the flux of f⃗ f→ through s.
To find the flux of a vector field through a closed boundary using the divergence theorem, calculate the divergence of the vector field and evaluate the triple integral of the divergence over the solid bounded by the boundary. In this case, the flux is 3 times the volume of the solid.
Explanation:The student is asking how to use the divergence theorem to find the flux of a vector field through a closed boundary. In this case, the vector field is defined as f(x, y, z) = ⟨x, y, 4z⟩ and the closed boundary is a solid bounded by the paraboloid z = x^2 + y^2 and the plane z = 9.
To use the divergence theorem, we need to calculate the divergence of the vector field, which is the sum of the partial derivatives of f with respect to each variable. In this case, the divergence is 3.
Then, we can use the divergence theorem to find the flux through the closed boundary by evaluating the triple integral of the divergence over the solid bounded by the paraboloid and the plane. In this case, the flux is 3 times the volume of the solid.

The flux of [tex]\(\vec{F}\)[/tex] through S is 24π.
To apply the divergence theorem, we first compute the divergence of [tex]\(\vec{F}\)[/tex]:
[tex]\nabla \cdot \vec{F} = \frac{\partial}{\partial x} (x) + \frac{\partial}{\partial y} (y) + \frac{\partial}{\partial z} (4z) = 1 + 1 + 4 = 6.[/tex]
The divergence theorem states that the flux of a vector field through a closed surface is equal to the triple integral of its divergence over the region enclosed by the surface.
Thus, we have:
[tex]\iint_S \vec{F} \cdot d\vec{A} = \iiint_W (\nabla \cdot \vec{F}) \, dV = \iiint_W 6 \, dV[/tex]
The region W is bounded below by the paraboloid [tex]\(z = x^2 + y^2\)[/tex], and above by the plane z = 4.
Converting to cylindrical coordinates, we have:
[tex]\iiint_W 6 \, dV = \int_0^{2\pi} \int_0^2 \int_{r^2}^4 6 \cdot r \, dz \, dr \, d\theta = 24\pi.[/tex]

Which statement is true about whether Z and B are independent events?
Z and B are independent events because P(Z∣B) = P(Z).
Z and B are independent events because P(Z∣B) = P(B).
Z and B are not independent events because P(Z∣B) ≠ P(Z).
Z and B are not independent events because P(Z∣B) ≠ P(B).
Answer:
Z and B are independent events because P(Z∣B) = P(Z).
Step-by-step explanation:
Z and B are independent events
When Z and B are independent events then
P(Z and B) = P(Z) * P(B)
P(Z∣B)= [tex]\frac{P(Z and B)}{P(B)}[/tex]
P(Z∣B)= [tex]\frac{P(Z)*P(B)}{P(B)}[/tex]
We cancel out P(B) on both sides
P(Z|B) = P(Z)

find the x intercepts of the parabola with vertex (5,-12) and y intercept (0,63)
Final answer:
To find the x-intercepts of the parabola with vertex (5,-12) and y intercept (0,63), substitute the vertex values into the equation of the parabola and find the value of the constant. Then, substitute the value of the constant back into the equation and solve for x to find the x-intercepts. The x-intercepts of the parabola are x = 3 and x = 7.
Explanation:
To find the x-intercepts of the parabola with vertex (5,-12) and y-intercept (0,63), we need to find the values of x when y is equal to zero. Since the vertex of the parabola is (5,-12), the equation of the parabola can be written as[tex]y = a(x-5)^2 - 12.[/tex] To find the value of a, we can use the y-intercept (0,63) by substituting the values of x and y into the equation.
[tex]63 = a(0-5)^2 - 12[/tex]
63 = 25a - 12
25a = 75
a = 3
Now that we have the value of a, we can substitute it back into the equation and solve for the x-intercepts:
[tex]0 = 3(x-5)^2 - 12[/tex]
[tex]3(x-5)^2 = 12[/tex]
[tex](x-5)^2 = 4[/tex]
x-5 = ±2
x = 5 ± 2
Therefore, the x-intercepts of the parabola are x = 3 and x = 7.
