~AH1807"Snoqualmie" is a name shared by a waterfall and a tribe of Native Americans. In a study of the cultural importance of the waterfall, two groups of the Snoqualmie tribe were randomly surveyed. One group consisted of Snoqualmie members living less than 25 miles from the waterfall. Another group consisted of Snoqualmie members living more than 25 miles from the waterfall. The researchers asked each member to rate the cultural importance of the waterfall as low, medium, or high. Data from the study are presented in the following table.
Members Living More Than 25 Miles from the Waterfall Members Living Less Than 25 Miles from the Waterfall Total
Low 25 17 42
Medium 8 21 29
High 5 12 17
Total 38 50 88
Required:
If the distributions of ratings are the same for those Snoqualmie members living less than 25 miles from the waterfall and those living more than 25 miles from the waterfall, what is equal to the expected count of members living less than 25 miles from the waterfall who rated the cultural importance as high?
Answer:
Expected count frequency= 17*50/88= 9.659
Step-by-step explanation:
Members Living More Members Living Less Total
Than 25 Miles Than 25 Miles
from the Waterfall from the Waterfall
Low 25 17 42
Medium 8 21 29
High 5 12 17
Total 38 50 88
We see that the total of the high row is 17 and the total of the members living less than 25 miles from the waterfall is 50 .
So using the formula :
Expected count frequency= row total * column total/ grand total
= 17*50/88= 9.659
All the expected frequencies can be found in a similar way and then compared to the observed frequency to test the chi square.

(-1 - 2)/(5+5)= -3/10
y - 2 = -3/10(x + 5)

Help with this please!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answer:
m∡A = 41.4°
m∡B = 48.6°
m∡C = 90°
a = 3[tex]\sqrt{7}[/tex]
b = 9
c = 12
Step-by-step explanation:
to find the length of side 'a' I used the Pythagorean Theorem to get:
a² + 9² = 12²
a² + 81 = 144
a² = 63
a = [tex]\sqrt{63}[/tex] which equals [tex]\sqrt{9}[/tex][tex]\sqrt{7}[/tex] which is 3[tex]\sqrt{7}[/tex]
to find m∡B I found the arcsin(B) = 9/12 to get 48.6
to find m∡A I subtracted the sum of 90 + 48.6 from 180°

Plz help me well mark brainliest if correct!
Answer:
The answer is B.
Step-by-step explanation:
The formula is Area = L x H
And remember perimiter is adding the legnth of all sides.
For A:
12 × 3 = 36
12 + 12 + 3 + 3 = 30
For B:
4 × 8 = 32
4 + 4 + 8 + 8 = 24
For C:
6 × 6 = 36
6 + 6 + 6 + 6 = 24
Hence, the answer is B, since B is the only one which meets the criteria.

Shelby is in a hot air balloon where the balloon is shaped like a sphere with a diameter of 50 ft find the amount of space occupied by the balloon use 3.14 for pie and round your answer to the nearest tenth
Answer:
50ft x 3.14 = 157ft
Step-by-step explanation:
It's asking for the circumference.
circumference formula: [tex]C = 2\pi r[/tex]
To give you a better idea of the concept:
To make it simple, in a circle, there is the radius, diameter, and then the circumference.
Radius: The distance half way across the circle (see attachment below).
Diameter: The distance across the circle (see attachment below).
Circumference: The distance around the circle (see attachment below).
As you see, the radius is only half way across, so 2 times the radius would give us the full distance across (diameter).
(But this doesn't matter for this question because it already gave you the diameter (50ft), this was only so I could maybe help you understand the concept a bit more).
Your question:
Alright, it's asking for the circumference; all you have to do is the diameter (50 ft) times pi (3.14).
[tex]50ft *3.14=157ft[/tex]

A. d(x) = P(x + 2) + 3
B. d(x) = P(x - 2) + 3
C. d(x) = P(x - 2) - 3
D. d(x) = P(x + 2) – 3
2. Which sequence of transformations takes the graph of y = k(x) to the graph of
y =-{k(x + 1)?
A. Translate 1 to the right, reflect over the x-axis, then scale vertically by a factor of
B. Translate 1 to the left, scale vertically by , then reflect over the x-axis.
C. Translate left by ž, then translate up 1.
D. Scale vertically by ž, reflect over the y-axis, then translate up 1.
Answer:
C.
Step-by-step explanation:
a) The equation of graph of the transformation of function is given by the relation d ( x ) = p ( x - 2 ) + 3
b) The sequence of transformation is translate 1 to the left, scale vertically by 1/2 , then reflect over the x-axis.
How does the transformation of a function happen?The transformation of a function may involve any change.
Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretched (multiplying outputs or inputs), etc.
If the original function is y = f(x), assuming the horizontal axis is the input axis and the vertical is for outputs, then:
Horizontal shift (also called phase shift):
Left shift by c units: y=f(x+c) (same output, but c units earlier)
Right shift by c units: y=f(x-c)(same output, but c units late)
Vertical shift:
Up by d units: y = f(x) + d
Down by d units: y = f(x) - d
Stretching:
Vertical stretch by a factor k: y = k × f(x)
Horizontal stretch by a factor k: y = f(x/k)
Given data ,
Let the function be represented as p ( x )
Now , the value of p ( x ) is
d ( x ) = p ( x - 2 ) + 3
The function is shifted 2 units to the right and 3 units up do match all the data points on the graph
b)
Let the parent function be y = k ( x )
Let the transformed function be y = -( 1/2 ) k ( x + 1 )
So , the series of transformation is given by
Translating 1 unit to the left , scale vertically by 1/2 , then reflect over the x-axis.
Hence , the transformed function is y = -( 1/2 ) k ( x + 1 )
