I’m out of school right now and i don’t know what the answer is this is the question. What’s the mean for 17 9 11 and 7?
Answer:
11
Step-by-step explanation:
Given the following question:
[tex]17,9,11,7[/tex]
To find the mean of any given data set we need to add all the values together and then divide that answer by the total amount of values in the data set.
[tex]17,9,11,7[/tex]
[tex]17+9+11+7[/tex]
[tex]9+11=20[/tex]
[tex]20+17=37[/tex]
[tex]37+7=44[/tex]
[tex]=44[/tex]
Now divide the answer by the total amount of values:
[tex]44[/tex]
[tex]a=4[/tex]
[tex]44\div4=11[/tex]
[tex]m=11[/tex]
Which means the mean of this given data set is "11."
Hope this helps.
Answer:
Mean = 11Step-by-step explanation:
The mean is the average number of the data.
Given data: 17, 9, 11, and 7To calculate the mean of the data, divide the sum of the data by the total numbers in the data. The quotient will be the average of the data.
[tex]\dfrac{17 + 9 + 11 + 7}{\text{Total digits in the data}}[/tex]
We can see 4 digits included in the data. Thus, the sum of the data will be divided by 4.
[tex]\dfrac{17 + 9 + 11 + 7}{4}[/tex]
Now, let's solve for the mean.
[tex]\dfrac{17 + 20 + 7}{4}[/tex]
[tex]\dfrac{44}{4} = 11[/tex]
Thus, 11 is the mean.

Step-by-step explanation:
Calculate the pay of the following day of a wage of $ 11/hour.
Answer:
93.5 dollars during Monday.
Step-by-step explanation:
Morning: 12:15 - 8 = 4hours 15 minutes
Afternoon: 17:15 - 13 = 4 hours 15 minutes
Total Time working = 4 hours 15 minutes + 4 hours 15 minutes
Total time working = 8 hours 30 minutes
30 minutes = 1/2 hour = 0.5 hours
Total time = 8.5 hours
Wage = 8.5 * 11 = 93.5 dollars for Monday.
In the expression y=3x+7 what does the input have to be in order for the output to be -2?
Answer:

then subtract the 7 on both sides to have '-9=3x'
divide by 3 on both sides
x= -3
Answer:
x=-3
Step-by-step explanation:
y=3(-3)+7
y=-9+7
y=-2

m<6 = (2x-5)°
m<4 = (x+5)°
9514 1404 393
Answer:
∠3 = 115°
Step-by-step explanation:
Angles 4 and 6 are "same-side interior angles", so are supplementary.
∠4 +∠6 = 180°
(x +5) +(2x -5) = 180
3x = 180
x = 60
The angles marked 3 and 6 are alternate interior angles, so are congruent. The measure of angle 3 is ...
∠3 = ∠6 = (2x -5)° = (2(60) -5)°
∠3 = 115°

The length of the arc is about 1.758 cm.
First, we need to determine the size of the angle. If we have pi/5 radians, we can convert that to 36 degrees, because pi radians is 180 degrees. Now, we know the measure of the arc is 36 degrees. 36 degrees out of 360 degrees is 10%.
Our arc is 10% of the circumference of the circle.
The circumference is 2(pi)r or 2(3.14)2.8 = 17.58 cm
Now, multiply 17.58 by 0.1 to get a total of 1.758 cm.

Solve this equation. Enter your answer in the box. –4(x – 26) = –200\
Answer:
x is 76
Step-by-step explanation:
im pretty sure, i just sloved it
Answer:
76.
Step-by-step explanation:
Simplifying
-4(x + -26) = -200
Reorder the terms:
-4(-26 + x) = -200
(-26 * -4 + x * -4) = -200
(104 + -4x) = -200
Solving
104 + -4x = -200
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-104' to each side of the equation.
104 + -104 + -4x = -200 + -104
Combine like terms: 104 + -104 = 0
0 + -4x = -200 + -104
-4x = -200 + -104
Combine like terms: -200 + -104 = -304
-4x = -304
Divide each side by '-4'.
x = 76
Simplifying
x = 76

Robert is designing hexagonal tiles that are made up of 12 identical right triangles, as shown. Write three equations robert can use the find the area A of the hexagonal tile in square centimeters.
Given:- Hexagon is made up of identical 12 triangles Sides of triangle :- 5cm,4cm,3cmTo Find:- 3 Equations for finding the area of the triangle Answer:-First method:-we know 12 triangles make up hexagon so we can say
12× Area of triangle = Area of hexagon
[tex]12 \times ( \frac{1}{2} \times base \times height) = area \: of \: hexagon[/tex]
[tex]12 \times \frac{1}{2} \times 3 \times 4 = area \: of \: hexagon \\ 12 \times 3 \times 2 = area \: of \: hexagon \\ 12 \times 6 = area \: of \: hexagon \\ 72cm {}^{2} = area \: of \: hexagon[/tex]
Second method:-we can see that there is a rectangle in the middle of the hexagon and 4 triangles (identical ) on 2 sides
According to question:-
sides of rectangle :- 8 cm and 6cmside of triangle is sameso area of hexagon= area of square+ 4 area of triangle
[tex]( l \times b ) + (4( \frac{1}{2} \times b \times h)) = area \: of \: hexagon[/tex]
[tex] (8 \times 6 ) + 4(\frac{1}{2} \times 4 \times 3) = area \: of \: hexagon \\ 48 + 24= area \: of \: hexagon \\ 72 {cm}^{2} = area \: of \: hexagon[/tex]
Third method:-we can see 2 square at the sides of the 4 triangle at the middle so we can say
side of square = 5cmsides of triangle = 4cm ,3cmArea of hexagon =4× area of triangle + 2 area of square
[tex]area \: of \: hexagon = (4\frac{1 }{2} × 4×3)+2(5×5) [/tex]
[tex]area \: of \: hexagon = 24+ 50 \\ area \: of \: hexagon = 74cm² \\ area \: of \: hexagon = 72 cm ² approx [/tex]
This approximation turn out bez in your question the area of 4 identical triangle is not equal to square formed by them
4 area of triangle = area of square
4×6 = 24 cm² not equal to 5² = 25 cm²
thats why there is approximation of 2 cm²
Tom started an entertainment company. The net value of the company (in thousands of dollars) ttt months after its creation is modeled by v(t)=4t^2-24t-28v(t)=4t 2 −24t−28v, left parenthesis, t, right parenthesis, equals, 4, t, squared, minus, 24, t, minus, 28 Tom wants to know when his company will be at its lowest net value. 1) Rewrite the function in a different form (factored or vertex) where the answer appears as a number in the equation. v(t)=v(t)=v, left parenthesis, t, right parenthesis, equals 2) How many months after its creation does the company reach its lowest net value? months
Answer:
4(t-3)^2-64
3 months
Step-by-step explanation:
1) Vertex form of the equation of the parabola is [tex]v(t)=4(t-3)^2-64[/tex]
2)3 months after its creation the company will reach its lowest net value.
The net value of the company after t months is given as:
[tex]v(t) = 4t^2-24t-28[/tex]
The above parabolic equation can be written as
[tex]v(t)=4(t^2-6t+9)-64[/tex]........(1)
What is the general equation of a parabola with vertex (h,k)?The general equation of a parabola is:
[tex]y = a(x-h)^2 +k[/tex]
where (h,k) is the vertex of the parabola.
So, (1) can be written in the vertex form as
[tex]v(t)=4(t-3)^2-64[/tex]
So, the vertex of the given parabola is (3, -64).
[tex]v'(t) = 8t - 24[/tex]
[tex]v''(t) =8[/tex]
So, from the second derivative test
t value corresponding to v'(t) =0 will give minimum value
[tex]8t-24=0[/tex]
[tex]t=3[/tex]
So, 3 months after its creation the company will reach its lowest net value.
Therefore, 1) Vertex form of the equation of the parabola is [tex]v(t)=4(t-3)^2-64[/tex]
2)3 months after its creation the company will reach its lowest net value.

To rewrite y(t) = 2 * sin (4 pi t) + 5 * cos (4 pi t) in the form Asin(wt+phi), you must first find the amplitude. Use c1=Asin(phi) and c2=Acos(phi) along with the Pythagorean identity to solve for A (amplitude.) previous question: By plugging in for c1 and c2, the equation should shift to be: Asin(wt+phi)=Acos(phi)sin(wt)+Asin(phi)cos(wt) Use the identity sin(x+y)=sin(x)cos(y)+cos(x)sin(y)
Answer:
The equation in standard form is [tex]y(t) = 5.390\cdot \sin (4\pi\cdot t +0.379\pi)[/tex].
Step-by-step explanation:
We use the following trigonometric identity:
[tex]\sin (\alpha + \beta) = \sin \alpha\cdot \cos \beta + \cos \alpha \cdot \sin \beta[/tex], [tex]\forall\,\alpha,\beta\in \mathbb{R}[/tex] (Eq. 1)
If we have formula [tex]y(t) = 2\cdot \sin (4\pi\cdot t)+5\cdot \cos (4\pi\cdot t)[/tex], by direct comparison with (Eq. 1):
[tex]A\cdot \cos \phi = 2[/tex] (Eq. 2)
[tex]A\cdot \sin \phi = 5[/tex] (Eq. 3)
Where:
[tex]A[/tex] - Amplitude, dimensionless.
[tex]\phi[/tex] - Phase angle, measured in radians.
By dividing (Eq. 3) by (Eq. 2), we get that:
[tex]\tan\phi = \frac{5}{2}[/tex]
[tex]\phi = \tan^{-1}\left(\frac{5}{2} \right)[/tex]
[tex]\phi = 0.379\pi\,rad[/tex]
From (Eq. 2) we find the amplitude:
[tex]A = \frac{2}{\cos \phi}[/tex]
[tex]A = \frac{2}{\cos 0.379\pi}[/tex]
[tex]A = 5.390[/tex]
Therefore, we find that equation in standard form is:
[tex]y(t) = A\cdot \sin (\omega\cdot t +\phi)[/tex] (Eq. 4)
Where [tex]\omega[/tex] is the angular frequency, measured in radians per second.
([tex]A = 5.390[/tex], [tex]\omega = 4\pi\,\frac{rad}{s}[/tex], [tex]\phi = 0.379\pi\,rad[/tex])
[tex]y(t) = 5.390\cdot \sin (4\pi\cdot t +0.379\pi)[/tex]
