The correct interpretation of the confidence interval is 90% confidence that the true proportion of all customers who have moved in the past five years is between 0.293 and 0.355.
The confidence interval is also not a guarantee that the true proportion is between 0.293 and 0.355. It is simply a statement of our confidence that the interval contains the true proportion.
This means that if the study were repeated many times, and constructed a 90% confidence interval each time, then 90% of the intervals would contain the true proportion.
In this case, the sample proportion is 0.324, which is within the confidence interval. This means that the sample data is consistent with the confidence interval. However, the sample proportion could be outside of the confidence interval if we had a different sample.

help me with this math question please I'm giving away brainliests
Answer:
Step-by-step explanation:
Given function in the question is,
[tex]f(x)=\frac{-2x^2-4x}{4x+8}[/tex]
[tex]=\frac{-2x(x+2)}{4(x+2)}[/tex]
[tex]=-\frac{1}{2}x[/tex] If [tex]x\neq -2[/tex]
Given function is not defined at x = -2
At x = -2,
[tex]f(-2)=\frac{1}{2}(2)[/tex]
[tex]=1[/tex]
Therefore, there is a hole in the graph at (-2, 1).
Graph of the function 'f' will be a straight line with a hole at (-2, 1).
Horizontal asymptote → None
Vertical asymptote → None
x-intercept → No x-intercept [Line passes through origin (0,0)]
y-intercept → No y-intercept [Line passes through origin (0,0)]
Hole → (-2, 1)
What is the value of x in the figure? (2x+15)°
Answer:
(2x + 15)° = 180°
2x = 180 - 15
2x = 165
x = 165/2
x = 82.5
If the function m not-equals 0 has an inverse function, which statement must be true? B not-equals 0
Answer:
Option a: m ≠ 0
Step-by-step explanation:
After a small online search, I've found that the complete question is:
If the function f(x) = m*x + b has an inverse function, which statement must be true?
a) m ≠ 0
b) m = 0
c) b ≠ 0
d) b = 0
Ok, if g(x) is an inverse of the function f(x), then:
g( f(x)) = x
f( g(x)) = x
Let's assume that f(x) = m*x + b has an inverse, and this inverse function is g(x).
Because f(x) is linear, g(x) is also linear, then:
g(x) = n*x + c
Let's find the values of A and B.
We know that:
f( g(x)) = x = m*(n*x + c) + b
then
x = m*n*x + m*c + b
Then we must have:
m*n = 1
(m*c + b) = 0
From the first equation m*n = 1
We get:
n = 1/m
The slope of the inverse function is one over the slope of the original function.
Because m is on the denominator, m can not be equal to zero (because a division by zero is not defined)
Then the correct option is the option a, m ≠ 0.

A

What is the solution to the following system of equations
5x + 4y = 40 6x + 4y =44
Answer:
X=4, y=5
Step-by-step explanation:
5x + 4y =40 equation 1
6x + 4y =44 equation 2
-1(5x + 4y)=-1(40) multiply equation 1 by -1 so equation will eliminate y
-5x - 4y=-40 modif equation 1
6x + 4y= 44 equation 2
x=4. Add above 2 equations
solve for y:
5x + 4y =40
5(4)+4y=40
20+4y =40
4y=20
y=5
check solution ;
6x+4y=44
6(4) + 4(5)=44
24 + 20=44
44=44

Select the correct answer from each drop-down menu. The length of side PQ is units. The length of side QR is about units. The perimeter of the parallelogram PQRS is about units. Reset Next
Answer:
The length of side PQ is 2 units.
The length of side QR is 2.24 units.
The perimeter of the parallelogram PQRS is about 8.48 units.
Step-by-step explanation:
The given figure is as follows :
To find - The length of side PQ is ....... units.
The length of side QR is about ......... units.
The perimeter of the parallelogram PQRS is ........
Solution -
From the figure , we can see that
P = (-5, 3)
Q = (-3, 3)
R = (-4, 1)
S = (-6, 1)
Now,
By distance formula, we get
PQ = √(3 - 3)² + (-3 + 5)²
= √0 + 2²
= √4
= 2
∴ we get
The length of side PQ is 2 units.
Now,
QR = √(1 - 3)² + (-4 + 3)²
= √(-2)² + (-1)²
= √4 + 1
= √5
= 2.236
∴ we get
The length of side QR is 2.24 units.
Now,
We know that,
Perimeter of Parallelogram = 2(a + b) where a is the base and b is the side
Here Given that,
a = 2
b = 2.24
So,
Perimeter of parallelogram PQRS = 2(2 + 2.24)
= 2(4.24)
= 8.48
∴ we get
The perimeter of the parallelogram PQRS is about 8.48 units.
Answer:
PQ 2 units
QR 2.24 units.

Let the vector \mathbf{v}v have an initial point at (-5, -5)(−5,−5) and a terminal point at (-3, 1)(−3,1). Determine the components of vector \mathbf{v}.V.
Answer:
The components of the vector are [tex]x = 2[/tex] and [tex]y = 6[/tex], respectively.
Step-by-step explanation:
The components of the vector is equal to the vector position of the terminal point relative to the initial point ([tex]\vec v[/tex]), that is:
[tex]\vec v = B(x,y) - A(x,y)[/tex] (1)
Where:
[tex]A(x,y)[/tex] - Initial point.
[tex]B(x,y)[/tex] - Terminal point.
If we know that [tex]A(x,y) = (-5,-5)[/tex] and [tex]B(x,y) = (-3,1)[/tex], then the vector is:
[tex]\vec v = (-3,1) -(-5-5)[/tex]
[tex]\vec v = (2, 6)[/tex]
The components of the vector are [tex]x = 2[/tex] and [tex]y = 6[/tex], respectively.

Which graph represents the solution to the inequality 3 + 5/2x ≥ 2 − 132?
Answer:
Option D.
Step-by-step explanation:
We have the inequality:
3 + (5/2)*x ≥ 2*x - 13/2
First, let's try to isolate x in one side of the inequality:
3 + (5/2)*x ≥ 2*x - 13/2
(5/2)*x ≥ 2*x - 13/2 - 3
(5/2)*x - 2*x ≥ - 13/2 - 3
Now all the terms with an x are in the left, and the terms without are in the right.
We can rewrite this inequality as:
(5/2)*x - (4/2)*x ≥ - 13/2 - 6/2
(1/2)*x ≥ -19/2
Now, multiplying both sides by 2 we get:
2*(1/2)*x ≥ (-19/2)*2
x ≥ - 19
So the graph will be a solid point in x = -19, and a ray that extends to the right (the values that are larger than -19)
The correct option is the last graph, option D.
