Answer:
The result of this test is 0.2156
Step-by-step explanation:
Given the data in the question;
The proportion of Americans having medical bill financial issues is ;
p = 20.9% = 0.209
CLAIM;
The problem is more severe among the cities
so
H₀ : p = 0.209
H₁ : p > 0.209 { this is our claim }
population n = 400
number of people that reported difficulty x = 90
so
sample proportion p" = x / n = 90 / 40 = 0.225
Test Statistics;
z = [ (p"-p) / √( (p(1-p))/n ) ]
we substitute
z = [ (0.225 - 0.209) / √( (0.209(1-0.209)) / 400 ) ]
z = [ 0.016 / √0.0004132976 ]
z = [ 0.016 / 0.0203297 ]
z = 0.787
P-VALUE
p-value = P( Z ≥ z )
p-value = P( Z ≥ 0.787 )
p-value = P( Z ≤ -0.787 )
from normal distribution table;
p-value = P( Z ≤ -0.787 ) = 0.2156
p-value = 0.2156
Therefore, The result of this test is 0.2156
h(x) = x ^ 2 - 7x - 8 1) What are the zeros of the function? Write the smaller first, and the larger second smaller I largerx = 2 ) What is the vertex of the parabola ?
Answer:
The zeros are x = -1 and x = 8
The vertex is (3.5, -20.25)
Step-by-step explanation:
When we have a quadratic equation like:
y = a*x^2 + b*x + c
The zeros of the function are the values of x such that:
a*x^2 + b*x + c = 0
And the solutions are given by the Bhaskara's equation, which is:
[tex]x = \frac{-b \pm \sqrt{b^2 - 4*a*c} }{2*a}[/tex]
And the vertex is at:
x = -b/2a
The y-value at the vertex is the function evaluated in that point.
In this case, we have the equation:
h(x) = x^2 - 7*x - 8
Then:
a = 1
b = -7
c= -8
Replacing these in the Bhaskara's equation we get:
[tex]x = \frac{-(-7) \pm \sqrt{(-7)^2-4*1*(-8)} }{2*1} = \frac{7 \pm 9 }{2}[/tex]
Then the two solutions are:
x = (7 - 9)/2 = -2/2 = -1 (this is the smaller one)
and
x = (7 + 9)/2 = 16/2 = 8 (this is the larger one)
And we will have the vertex at:
x = -(-7)/2*1 = 7/2 = 3.5
Evaluating h(x) in 3.5 we get:
h(3.5) = (3.5)^2 - 7*(3.5) - 8 = -20.25
Then the vertex is the point:
(3.5, -20.25)

Gale owns a car that is worth $9,500 but she still owes $7,400 on the car loan. She has a student loan in the amount of $6,000 and she has a savings account with a balance of $1500. The balance on her credit card is $3200. What is her net worth?
Answer:
$8000
Step-by-step explanation:
Given: Car worth = $9,500, car loan = $7,400. Student loan = $6,000, savings account = $1500. The balance on her credit card is $3200.
Formula: Total Assets - Total Liabilities - Intangible Assets = Tangible Net Worth.
To find: Gale's net worth
Solution: You can calculate your net worth by subtracting your liabilities (debts) from your assets.
Firstly, calculate the total amount of assets by adding them together;
Total assets = Car worth + car loan + Student loan + savings account + balance on her credit card =
$9,500 + $7,400 + $6,000 + $3200 =$26,100
Secondly, calculate the Liabilties by adding them together;
Car loan + Student loan =
$7,400 + $6,000 = $13,400
Then, calculate the Intangible Assets by adding them together;
Savings account + The balance on her credit card =
$1500 + $3200 = $4700
Finally substact the total amounts;
$26,100 - $13,400 - $4700 = $8000
(Note:- If your assets exceed your liabilities, you will have a positive net worth. Conversely, if your liabilities are greater than your assets, you will have a negative net worth.)

need help with working perimeter and area please
Answer:
Area = 228 m²
Perimeter = 60 m
Step-by-step explanation:
The figure given shows a rectangle that has a cut triangular portion.
✔️Area of the figure = area of rectangle - area of the triangular cut portion
= L*W + ½*bh
Where,
L = 20 m
W = 12 m
b = 20 - (8 + 8) = 4 m
h = 6 m
Plug in the values
Area = 20*12 - ½*4*6
Area = 240 - 12
Area = 228 m²
✔️Perimeter = perimeter of rectangle - base of the triangular cut portion
= 2(L + W) - b
L = 20 m
W = 12 m
b = b = 20 - (8 + 8) = 4 m
Plug in the values
Perimeter = 2(20 + 12) - 4
= 2(32) - 4
= 64 - 4
Perimeter = 60 m

The square of a number is equal to 10 less than 7 times that number. What are the two possible solutions?
Answer:
x = 5, 2
Step-by-step explanation:
x^2 = 7x - 10
x^2 -7x + 10 = 0
(x - 2)(x - 5) = 0
x = 5, 2
Two of the angles in a triangle measure 81° and 86°. What is the measure of the third angle?
Answer:
13°
Step-by-step explanation:
The reason is because the sum of all the angles in a triangle add up to 180°, so to find the last angle you add 81°+86°=167°
Subtract: 180°-167°=13°

A car rental company charges 45.95 per day plus 0.35 per mile Rachel rented a car for two days and was charged 117.10 how many miles did Rachel drive the car 25 miles? 72 miles 117 miles 203 miles
Answer:
203.28 miles
Step-by-step explanation:
Given data
charge per day= $45.95
charge per mile= 0.35
The expression for the total is
y= 45.95+0.35x
where x is the number of miles
We want to find the value of x when y= 117.10
substitute
117.10=45.95+0.35x
117.10-45.95=0.35x
71.15=0.35x
x= 71.15/0.35
x=203.28 miles

HELP ASAPPPPPP( i need it before 5:30)
Answer: I would say that x = 10 degrees
Step-by-step explanation:
The angle has a square, meaning it is a right angle. Right angles are 90 degrees, and you're given 80 degrees + x.
90 - 80 = 10
Hope this helps!
Answer:
10 degrees
Step-by-step explanation:
First off complementary angles require the sum of both adjacent angles to equal 90 degrees. You are already given the degrees of one of the adjacent angles so all you need to do is a geometric proof. 90 = 80 + x and subtract 80 from each side to get 10 = x.
tell whether the angles are adjacent or vertical. Then find the value of x
Step-by-step explanation:
8.Solution:
x+35=90(adjacent)
x=90-35
x=55
9.Solution:
x=128(vertical)
10.Solution:
x+117=180(adjacent)
x=180-117
x=63
11.Solution:
75=4x-25(vertical)
75+25=4x
100/4=x
x=25
12.Solution:
4x+2x=90(adjacent)
6x=90
x=90/6
x=15
13.Solution:
7x+x+20=180(adjacent)
8x=180-20
x=170/8
x=21.25
