The test statistics and the p-value from the research sampling will be 1.57 and 0.119.
What is test statistic?It should be noted that a test statistic simply means a number that's used to describe how the observed value is far from the null hypothesis.
In this case, the test statistics is 1.57. The p value will be:
= 2 × 0.0593
= 0.119
Therefore, the test statistics and the p-value from the research sampling will be 1.57 and 0.119.

Question 8: 3 + x
(x - 2)2 + (y +13)2 = 150
Center:
Radius:
Answer:
Center: (2, -13)
Radius: 5√6
Explanation:
Equation: (x - 2)² + (y +13)² = 150
Circle Formula:
(x - h)² + (y - k)² = r²
where (h, k) is the center points, r is radius
Rewrite the equation:
(x - (2) )² + (y - (-13))² = (√150)²
Identify following's:
h = 2, k = -13, radius = √150 = 5√6

Describe how the variable h and the variable k of the general formula for a cube root function effects the graph. The general formula is y=a^3sqrt x-h+k
Using translation concepts, it is found that the variable h shifts the function horizontally while the variable k shifts the function vertically.
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.
The cube root function is given by:
[tex]y = \sqrt[3]{x}[/tex]
The translated function is given by:
[tex]y = \sqrt[3]{x - h} + k[/tex].
The variables work as follows:
Variable h is in the domain, hence it changes the function horizontally.Variable k is in the range, hence it changes the function vertically.More can be learned about translation concepts at https://brainly.com/question/4521517

To find :-
The value of x
Given :-
Here 2 angles are given
142°, and (3x + 22)°
Solution :-
We can see here the 2 lines intersect each other.
And the angle is formed
Since the angles are just opposite to each other so they are equal.
142° = (3x + 22)° {vertically opposite angles}
[tex]142 - 22 = 3x \\ 120 = 3x \\ \frac{120}{3} = x \\ 40 = x[/tex]
Result :-
The value of x is 40°.

A prism is completely filled with 270 cubes that have edge length of 13
in.
What is the volume of the prism?
Answer:
593190 cubic inches
Step-by-step explanation:
to solve this equation you must first find out the volume of one cube
that can be modeled by 13*13*13 or more simply 13^3
13^3 = 2197
then you multiply that to 270
2197 * 270 = 593190
that is your answer
What is the area, measured in square centimeters, of the green shape
pictured below? Do not include units in your answer.
Answer:
21
Step-by-step explanation:
To find the area of a parallelogram, we can split this shape up into a rectangle and two right triangles.
The rectangle:
The rectangle has dimensions of 4 by 3 centimeters therefore the area would be 4*3=12 cm squared
two right triangles:
The area of a triangle is 1/2 base * height, but since there are two triangles it would just be the base times the height. The base is 3 cm and the height is 3 so 3*3=9
Next, we add the two areas together: 12+9 = 21

Step-by-step explanation:
A rectangular prism has a length of 4 in., a width of 2 in., and a height of 2 1/2 in.
The prism is filled with cubes that have edge lengths of 1/2 in.
How many cubes are needed to fill the rectangular prism?
Enter your answer in the box.
Answer:
160
Step-by-step explanation:
Each cube is 1/2 inch, so there will be 2 cubes in each 1 inch of length. The dimensions of the prism in terms of the number of cubes are ...
length: 4 in ⇒ 4×2 = 8 cubes
width: 2 in ⇒ 2×2 = 4 cubes
height: 2 1/2 in ⇒ (2 1/2)×2 = 5 cubes
Then the number of cubes required to fill the prism is ...
8 × 4 × 5 = 160 . . . . cubes
The volume of the prism is equivalent to that of 160 1/2-inch cubes.

cosA=Base/Hypotenusecos75=B/10B=10cos75B=2.58ftAnswer:
a) 67°
b) 2.6 ft
Step-by-step explanation:
Part (a)This problem can be modeled as a right triangle (see attachment 1), where the wall and the ground are the legs, and the ladder is the hypotenuse. Therefore, we can use the sine trig ratio to find the angle.
Trig Ratio
[tex]\sf \sin(\theta)=\dfrac{O}{H}[/tex]
where:
[tex]\theta[/tex] is the angleO is the side opposite the angleH is the hypotenuse (the side opposite the right angle)Given:
[tex]\theta[/tex] = xO = wall = 9.2H = ladder = 10Substituting the given values into the ratio and solving for x:
[tex]\implies \sf \sin(x)=\dfrac{9.2}{10}[/tex]
[tex]\implies \sf x=\sin^{-1}\left(\dfrac{9.2}{10}\right)[/tex]
[tex]\implies \sf x=67^{\circ}\:(nearest\:degree)[/tex]
Part (b)(see attachment 2)
Let y be the distance the foot of the ladder and the foot of the building
We can find y by using the cos trig ratio:
[tex]\sf \cos(\theta)=\dfrac{A}{H}[/tex]
where:
[tex]\theta[/tex] is the angleA is the side adjacent the angleH is the hypotenuse (the side opposite the right angle)Given:
[tex]\theta[/tex] = 75°A = grounds = yH = ladder = 10Substituting the given values into the ratio and solving for x:
[tex]\implies \sf \cos(75^{\circ})=\dfrac{y}{10}[/tex]
[tex]\implies \sf y=10\cos(75^{\circ})[/tex]
[tex]\implies \sf y=2.6\:ft\:(nearest\:tenth)[/tex]

Answer:
x = 11
Step-by-step explanation:
All the sides of a rhombus are equal, so you can set the equations equal to one another.
2x + 46 = 7x - 9
Subtract 2x from both sides
46 = 5x - 9
Add 9 to both sides
55 = 5x
Divide both sides by 5
x = 11

A pack of red pens can be divided into equal shares among 3, 5, 6 and 9 teachers with no pen left over?
Answer:
90 red pens
Step-by-step explanation:
we need to find the least common multiple of the numbers 3 , 5 , 6 , 9
6 = 2 × 3
9 = 3²
then
LCM(3,5,6,9) = 2×5×3² = 2×5×9 = 90
The number 90 can be divided into 3 ,5 ,6 ,9 with no remainder
Therefore the pack must have 90 pens or a multiple of 90

8. Compare the function g(x) modeled by the graph and the functionf (x) =
21x + 2) + 3.
True or false. Explain.
a) f(x) has a greater y intercept
b) g(1) > f(-1)
c) f(x) increases at a faster rate than g(x)over interval [0, 3).
Answer:
a) false
b) true
c) true
Step-by-step explanation:
Part (a)The y-intercept of a function is the point when x = 0
⇒ f(0) = 2|0 + 2| + 3
= 2|2| + 3
= 4 + 3
= 7
From inspection of the graph, the y-intercept of g(x) is (0, 7)
Therefore, the y-intercepts of f(x) and g(x) are the same.
"f(x) has a greater y-intercept" → false
Part (b)
From inspection of the graph, g(1) = 6
⇒ f(-1) = 2|-1 + 2| + 3
= 2|1| + 3
= 2 + 3
= 5
Therefore, g(1) > f(-1) → true
Part (c)The average rate of change of function f(x) over the interval a ≤ x ≤ b is given by:
[tex]\dfrac{f(b)-f(a)}{b-a}[/tex]
From inspection of the graph:
g(0) = 7
g(3) = 4
[tex]\textsf{average rate of change of g(x)} \implies \dfrac{4-7}{3-0}=-1[/tex]
f(0) = 7 (from part (a))
f(3) = 2|3 + 2| + 3
= 2|5| + 3
= 10 + 3
= 13
[tex]\textsf{average rate of change of f(x)} \implies \dfrac{13-7}{3-0}=2[/tex]
Function g(x) decreases over [0, 3] at the rate of -1
Function f(x) increases over [0, 3] at the rate of 2
Therefore, "f(x) increases at a faster rate than g(x) over interval [0, 3]" is true
**Please see the attached graph for reference**
The interval [0, 3] is shaded in grey
f(x) is shown in red
The added 2 points are f(-1) and g(1)
If f(x)= 5x-1 and g(x)=3x+2, find f(g(x)).
Pls help me!!
Answer:
15x+9
Step-by-step explanation:
f(g(x))
=f(3x+2)
=5(3x+2)-1
=15x+9

A manufacturer sells mirrors in the shapes of squares. The smallest size mirror the manufacturer sells has an area of 4 ft ^2. The largest size mirror has an area of 9 ft^2.
which graph represents the possible side lengths of the mirror sold by the manufacturer.
The domain of the graph of the that represents the side length of the mirror is 2 ≤ x ≤3
How to determine the graph?The given parameters are:
Shape = SquareSmallest area = 4ft²Largest area = 9ft²The area (y) of a square of side length x is:
y = x²
Make x the subject
x = √y
When y = 9, we have:
x = √9 = 3
When y = 4, we have:
x = √4 = 2
This means that the domain of the graph of the that represents the side length of the mirror is 2 ≤ x ≤3
