Given data set:
6, 2, 7, 12, 6, 1, 7, 1, 9, 7, 8
Find the mean, median, and mode of the data set.
Answer:
see below
Step-by-step explanation:
6, 2, 7, 12, 6, 1, 7, 1, 9, 7, 8
First put the numbers in order from smallest to largest
1,1, 2,6,6, 7, 7, 7, 8, 9, 12
The mean is adding all the numbers and dividing by the number of numbers
( 1+1+ 2+6+6+ 7+ 7+ 7+ 8+ 9+ 12 )/11
66/1 =6
The mean is 6
The median is the middle
There are 11 terms
11/5 = 5.5 so 6 is the middle number
1,1, 2,6,6, 7, 7, 7, 8, 9, 12
7 is the median
Mode is the most often
7 appears three times so it is the mode

Write an equation of the line that is perpendicular to the line y = 4x - 10 that passes through the point (-16, 2).
A)
y = - 3x - 2
y = -4x+6
y=-3x+2
y = 4x + 2
Answer:
y = -1/4x -2
Step-by-step explanation:
the perpendicular slope would be -1/4
2 = -1/4 (-16) + b
b = -2
the equation should be y = -1/4x -2

What is the median of the data set represented by the dot plot?
Answer:
The median is 5.
Step-by-step explanation:
To find the median you have to do steps, (they are really easy):
The median is like the middle of the graph so just try finding the middle, ( i could explain this in a different way but it's hard to explain) Hope this helps.
Hey, I know you already found the median, but if you need help with anything else like that I'll show you!
Mean:
Step 1: Add up all data values to get the sum
Step 2: Count the number of values in your data set
Step 3: Divide the sum by the count
Mode:
Mode is the value or values in the data set that are the most common. To remember what mode is, think of most. Mode, Most.
Range:
The Range is the difference between the lowest and highest values. So, if we had a data set that read 5 5 3 6 9, you would have to find the lowest and highest number. For this set, thats 3 and 9. subtract them to get the sample range. 9 - 3 = 6.

Find the 91st term of the arithmetic sequence 5, -14, -33, ...
Answer:
a(91) = -1705
Step-by-step explanation:
Each successive term is 19 less than the previous term, so the common difference is 19, and the general term is a(n) = a(1) - 19(n - 1).
Thus, the 91st term is a(91) = 5 - 19(91 - 1), or
a(91) = 5 - 1710, or
a(91) = -1705
The 91st term of the arithmetic sequence is -1705.
What is Arithmetic progression?An arithmetic progression is a sequence of numbers such that the difference of any two successive members is a constant.
Given that an arithmetic sequence 5, -14, -33, ...
nth term of an AP is, a(n) = a + (n-1)d
Each successive term is 19 less than the previous term, so the common difference is 19, and the general term is a(n) = a(1) - 19(n - 1).
Thus, the 91st term is
a(91) = 5 - 19(91 - 1)
a(91) = 5 - 1710
a(91) = -1705
Hence, The 91st term of the arithmetic sequence is -1705.

In the middle of a basketball court, the circle has a diameter of 5 feet. If
Mrs. Gilbertson's daughter walked around the circle 12 times, how far did
she walk? Use 3.14 for TT. *
Answer:
The distance that Mrs. Gilbertson's daughter walked was 188.4 feet
Step-by-step explanation:
Here we have that Mrs. Gilbertson's daughter walked round the circle 12 times where the diameter of the circle = 5 ft., therefore, the circumference of the circle, the distance walked round each of the 12 times = π·D
Where:
D = 5 ft
Hence, circumference = π × 5 = 3.14 × 5 = 15.7 ft
Therefore, by walking round the circle 12 times, the total distance that Mrs. Gilbertson's daughter walked = 12 × 15.7 = 188.4 ft.

What is the value of x?
Answer:
5 sqrt(3)
Step-by-step explanation:
Since this is a right triangle
sin theta = opposite side/ hypotenuse
sin 60 = x /10
10 sin 60 = x
10 sqrt(3) /2 =x
5 sqrt(3) =x
Answer:
5√3
Step-by-step explanation:
The sine function ties together the information at hypotenuse = 10, opposite side = x and angle of elevation = 60 degrees:
sin 60 degrees = opp side / hypotenuse = x/10.
Therefore, x = 10 sin 60 degrees = √3/2, and so x = 10√3/2 = 5√3 (equal to the third answer choice).

A telephone pole is 8 meters tall and a pigeon is standing on the ground 6 meters
from the pole. If the pigeon flies from where it is standing to the top of the
telephone pole, how far will it fly?
Your answer will be 10m.
We can picture this question as a right-angled triangle, where the pole is one leg, and the distance from the pole to the pigeon on the ground is another leg. Using this, the hypotenuse would be the distance that the pigeon would travel to get from the ground to the top of the pole, presuming it flies in a straight line, and so we can use Pythagoras’ Theorem to find the length of the hypotenuse.
a² + b² = c²
(6)² + (8)² = c²
36 + 64 = c²
100 = c²
10 = c

Answer:
The perimeter of triangle is 30ft.
Step-by-step explanation:
First you have to find the value of a using Pythogoras Theorem, a² + b² = c² where a and b is the sides and c is the hypotenuse :
[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]
[tex] {a}^{2} = {c}^{2} - {b}^{2} [/tex]
[tex]a = \sqrt{ {c}^{2} - {b}^{2} } [/tex]
Let b = 12,
Let c = 13,
[tex]a = \sqrt{ {13}^{2} - 12 {?}^{2} } [/tex]
[tex]a = \sqrt{25} [/tex]
[tex]a = 5feet[/tex]
Next you have to find the perimeter of triangle by adding all the sides together :
[tex]perimeter = 5 + 12 + 13[/tex]
[tex]perimeter = 30feet[/tex]
Write an equation of the line that passes through (−1, 3) and is perpendicular to the line y=1/9x−1.
Answer:
Step-by-step explanation:
General equation of line
y = mx + c
m is slope
y = (1/9)x - 1
1/9 is slope
Since the other line that passes through the point is perpendicular, the product of both slopes is -1
1/9 * m = -1
m = -9
Using point-slope method
y-y1 = m(x-x1)
y-3 = -9(x-(-1))
y-3 = -9(x + 1)
y-3 = -9x -9
y = -9x-6
