Suppose you know the population average wage in the manufacturing industry in California is $24.66 per hour. You take a survey 30 people that work in manufacturing in Utah to answer the following research question. Is the population average manufacturing wage in Utah less than $24.66 per hour, the population average manufacturing wage in the California?
Answer:
Yes
Step-by-step explanation:
Given:
Number of people (n) = 30
Mean wage in california = 24.66
Incomplete information;
Sample mean =23.41
Standard deviation = 2.35
Yes, the population average manufacturing wage in Utah less than $24.66 per hour, the population average manufacturing wage in the California

Answer:
y = 12 -x0 ≤ y ≤ 12Step-by-step explanation:
The perimeter of a rectangle is given by ...
P = 2(L +W) . . . . . where L and W represent the length and width
Filling in the given values, we have ...
24 = 2(y +x)
Solving for y, we get ...
12 = y + x . . . . . divide by 2
y = 12 -x . . . . . . subtract x
The length y is the difference between 12 and the width x.
__
We want both x and y to be non-negative, so possible values of y range from 0 to 12.
The radius of a sphere is 6 units.
Which expression represents the volume of the sphere,
in cubic units?

Answer:
B. ⁴/3π(6)³
Step-by-step explanation:
Formula for volume of a sphere = ⁴/3πr³
Where,
radius (r) = 6 units
Plug in the given value into the volume formula
Volume of the sphere = ⁴/3 × π × (6)³
Volume of the sphere = ⁴/3π(6)³
The expression that represents the volume of the given sphere is therefore ⁴/3π(6)³ cubic units.
The expression for the volume of the sphere is:
V = (4/3)*3.14*(6)^3
Which expression represents the volume?
For a sphere of radius R. the volume is given by:
V = (4/3)*pi*R^3
Where pi = 3.14
Here we know that the radius is 6 units, so we can write the volume as:
V = (4/3)*3.14*(6)^3
As you can see, the second option (counting from the top) is the correct one.

52 POINTS I need help!
Question 1
The vertex form of the equation of a vertical parabola is given by
, where (h, k) is the vertex of the parabola and the absolute value of p is the distance from the vertex to the focus, which is also the distance from the vertex to the directrix. You will use the GeoGebra geometry tool to create a vertical parabola and write the vertex form of its equation. Open GeoGebra, and complete each step below. If you need help, follow these instructions for using GeoGebra.
Part A
Mark the focus of the parabola you are going to create at F(6, 4). Draw a horizontal line that is 6 units below the focus. This line will be the directrix of your parabola. What is the equation of the line?
Part B
Construct the line that is perpendicular to the directrix and passes through the focus. This line will be the axis of symmetry of the parabola. What are the coordinates of the point of intersection, A, of the axis of symmetry and the directrix of the parabola?
Part C
Explain how you can locate the vertex, V, of the parabola with the given focus and directrix. Write the coordinates of the vertex.
Part D
Which way will the parabola open? Explain.
Part E
How can you find the value of p? Is the value of p for your parabola positive or negative? Explain.
Part F
What is the value of p for your parabola?
Part G
Based on your responses to parts C and E above, write the equation of the parabola in vertex form. Show your work.
Part H
Construct the parabola using the parabola tool in GeoGebra. Take a screenshot of your work, save it, and insert the image below.
Part I
Once you have constructed the parabola, use GeoGebra to display its equation. In the space below, rearrange the equation of the parabola shown in GeoGebra, and check whether it matches the equation in the vertex form that you wrote in part G. Show your work.
Part J
To practice writing the equations of vertical parabolas, write the equations of these parabolas in vertex form:
focus at (-5, -3), and directrix y = -6
focus at (10, -4), and directrix y = 6.
Answer:
Step-by-step explanation:
A. Directrix: y = 4-6 = -2
:::::
B. Axis of symmetry: x = 6
Axis of symmetry intersects directrix at (6,-2)
:::::
C . Vertex is halfway between focus and directrix, at (6,1)
:::::
D. The focus lies above the directrix, so the parabola opens upwards.
:::::
E. Focal length p = 1/(4×0.5)
:::::
F. p = 0.5

Step-by-step explanation:
h.We start with a circle and a line that goes through the center of the circle (C) and one vertex of the triangle (E).
Using the point on the line opposite the vertex as a center (D), we draw an arc with the same radius the circle has.
The two points of intersection with the circle are the other two vertices of the inscribed triangle (F, G).

0.33x + 5.22 = 1097.19 . . . . . . . . . simplify
0.33x = 1091.97 . . . . . . . . . . . . subtract 5.22
x = 3309 . . . . . . . . . . . . . . . . divide by 0.33
y = 3(3309) +58 = 9985
$3309 is invested at 6%; $9985 is invested at 9%.

Step-by-step explanation:
a standard 52-card deck has 13 diamond cards (1,2,3,4,5,6,7,8,9,10,J,Q,K)
P(diamond) = number of diamonds/number of cards in a deck = 13/52

Find the area of the trapezoid below in square centimeters (cm). The area of the trapezoid is
square centimeters. Enter the answer as decimal number
14 cm
8 cm
7 cm
8 cm
21 cm
The solution is
Answer:
122.5
Step-by-step explanation:
Use the area formula for a trapezoid (attached below as an image):
A = area in sq cm
a = top base
b = bottom base
h = height
Correspond the correct values with the variables:
a = 14
b = 21
h = 7
A = 1/2 * (14 + 21) * 7
A = 1/2*(35)*7
A = 17.5 * 7
A = 122.5 sq cm

If the two angles are complementary, find the measure of each of angle.
Answer:
D 40 and 50
Step-by-step explanation:
Complimentary angles are equal to 90
Answer: D, 40 and 50
Steps:
1. Since complementary angles equal 90 degrees, 4r + 5r = 90
2. 4r + 5r is 9r
3. This makes the equation, 9r=90
4. Divide both sides by 9, and then you get r=10
5. Substitute r=10 into 4r and 5r
6. This should make 4(10) and 5(10)
7. Multiply and then get 40 and 50

Type your answer into the box. X 30° Calculate the size of angle x. angle x =
Answer:
x = 60°Step-by-step explanation:
We know:
All triangles have internal angles that add up to 180°.
And
All right triangles have acute angles that up to 90°.
Therefore
x + 30° + 90° = 180°
x + 120° = 180° |subtract 120° from both sides
x + 120° - 120° = 180° - 120°
x = 60°orx + 30° = 90° |subtract 30° from both sides
x + 30° - 30° = 90° - 30°
x = 60°The size of angle x will be 60°
TriangleIt is a plane figure with three straight sides and three angles.
What are steps to solve this problem?The steps are as follow:
As per rule of triangle, the sum of all three internal angle must be equal to 180°The given triangle is right angle triangle having one angle 30° and other we have to findGiven:z = 90°
y = 30°
x = ?
∴ x + y + z = 180°
∴ x + 30 + 90 = 180
∴ x + 120 = 180
∴ x = 60°
So the size of angle x will be 60°

x-intercept = (2, 0)
y-intercept = (0, 7.5)
Step-by-step explanation:
The x-intercept can be found by setting y = 0. Thus,
[tex]15x + 4(0) = 30 \Rightarrow x = 2[/tex]
Therefore, the x-intercept is (2, 0).
The y-intercept can be found by setting x = 0:
[tex]15(0) + 4y = 30 \Rightarrow y = 7.5[/tex]
Therefore, the y-intercept is at (0, 7.5)
