Answer:
The finding is significant at both α = 0.05 and α = 0.01.
Step-by-step explanation:
Given that:
Null hypothesis : H0: p = 0.65 against the Alternative Ha: p < 0.65,
The test statistic ; z test = - 2.35
From the test statistic value, we can obtain the p value of the test :
To determine if the claim is significant at both α = 0.05 and α = 0.01
We compare the Zstatistic and Zcritical values
If Zstatistic < Zcritical ; then we reject H0; if otherwise, we fail to reject H0
Zcritical at 95% one tailed = - 1.645 (left tail)
Zcritical at 95% one tailed = -2.326 (left tail)
- 2.35 < - 1.645
-2. 35 < 2.326
Since, Zstatistic < Zcritical;
The finding is significant at both α = 0.05 and α = 0.01.

Step-by-step explanation:
Identify the domain and range, then evaluate each function for the given value of x.
(I do not need much help for the domain and range but mostly the "Find f(5)"
Answer:
See below
Step-by-step explanation:
Domains are the first values and range are the second values given in the brackets.
Domain = {10, - 2, 5, 3}
Range = {7, 4, 3, 10}
I the third bracket, at x = 5, y is 3.
So,
f(5) = 3
1. The function f(x)=-3-2 has a domain of the following values {0,4,-1}. Show the domain and range in the mapping diagram below.
2. For what values of x, would not be in the domain of the function y= ⟌ x+4?

9,185 miles 380 yards divided by 4,590
9514 1404 393
Answer:
2 miles 2 yards
Step-by-step explanation:
There are 1760 yards in a mile, so you are effectively performing the division ...
(9185 380/1760) ÷ 4590
where the number in parentheses is a mixed number of miles.
You do this division the same way you do any mixed-number division. There are different possible methods you can use. One of them is to convert the mixed number to an improper fraction, then divide.
9185 380/1760 = 9185 19/88 = (88·9185 +19)/88 = 808299/88
Then this is divided in the usual way:
[tex]\dfrac{808299}{88}\div4590=\dfrac{808299}{88\cdot4590}=\dfrac{808299}{403920}=2\dfrac{459}{403920}=2\dfrac{1}{880}[/tex]
Finding the quotient and remainder is straightforward. Reducing the fraction involves finding common factors in the numerator and denominator. As it turns out, 459 is a factor of 403920, so the fraction reduces as shown.
Now, we need to convert 1/880 miles back to yards.
((1/880) mi) × (1760 yd/mi) = 2 yd
So, the quotient you seek is ...
2 miles 2 yards

Nicole parks cars. She earns $9.75 per hour plus 10% of the parking fees that are
collected. If the total fees during a 5-hour shift are $360, how much does Nicole
earn?
Answer:
$84.75
Step-by-step explanation:
Given that she earns $9.75 per hour plus 10% of the parking fees that are collected, her income is of 2 folds; an hourly rate and an amount collected based rate.
If the shift is for 5 hours, her income based on
Hourly rate = 5 * $9.75
= $48.75
The amount collected based rate
= 10% * $360
= 10/100 * $360
= $36
Her total earnings will be
= $48.75 + $36
= $84.75

Use the ordered pairs from the graph to fill in the missing values in the table.
Enter your answer by filling in the boxes.
Answer:
x is 4 when y is 180
y is 540 when x is 12
Step-by-step explanation:
The ordered pair to complete the table is (4, 180), (8, 360), and (12, 540).
What is graph?A graph is a structure made up of a collection of things, where some object pairs are conceptually "connected." The items are represented by mathematical abstractions known as vertices, and each pair of connected vertices is referred to as an edge.
Given:
From the graph, at y = 180 miles, x = 4 hours
At x = 8 hours, y = 360 miles,
At x = 12 hours, y = 540 miles,
You can also calculate this by the concept of ratio,
8 / 360 = 12 / y
8y = 12 × 360
y = 4320 / 8
y = 540 miles
Therefore, the ordered pair to complete the table is (4, 180), (8, 360), and (12, 540).

Determine the values of the unlabeled parts of the triangle.
OA) ZQ = 63.4°, PQ = 1.84, QO = 4.47
OB) ZQ = 26.6°, PQ = 2, QO = 5.12
OC) ZQ = 63.4º, PQ = 2, QO = 4.47
D)
ZQ = 63.4°, PQ = 1.84, QO = 5.12
Answer:
∠Q = 63.4º, PQ = 2, QO = 4.47
Step-by-step explanation:
A triangle is a polygon with three sides and three angles. There are different types of triangles such as the equilateral triangle, isosceles triangle, scalene triangle, right angled triangle.
Triangle POQ is a right angled triangle because ∠P = 90°. Also, ∠O = 26.6°.
Therefore in ΔPOQ: ∠P + ∠O + ∠Q = 180° (sum of angles in a triangle).
90 + 26.6 + ∠Q = 180
∠Q + 116.6 = 180
∠Q = 180 - 116
∠Q = 63.4°
We can find PQ and QO using sine rule. Sine rule for ΔPOQ is given as:
[tex]\frac{PO}{sin Q}= \frac{PQ}{sinO}= \frac{QO}{sin P}\\\\Finding\ PQ :\\\\\frac{PO}{sin Q}= \frac{PQ}{sinO}\\\\\frac{4}{sin(63.4)} =\frac{PQ}{sin(26.6)}\\\\PQ= \frac{4}{sin(63.4)} *sin(26.6)\\\\PQ = 2\\\\Also\ finding\ QO:\\\\\frac{PO}{sin Q}= \frac{QO}{sinP}\\\\\frac{4}{sin(63.4)} =\frac{QO}{sin(90)}\\\\QO=\frac{4}{sin(63.4)} *sin(90)\\\\QO = 4.47[/tex]

What is the equation of the line that passes through the point (3.4) and has a slope of 5?
Answer:
y = 5x - 11
Step-by-step explanation:
The equation is y = mx+b where m is the slope and b is the y intercept
y = 5x + b (now lets substitute the coordinate in to solve for b)
4 = 5(3) + b
4 = 15 +b
b = -11
y = 5x - 11

The perimeter of a certain scalene triangle is 100 inches. The side lengths
of the triangle are represented by 5x, 3x+30, and 2x+10, respectively. What
is the length, in inches, of the longest side of the triangle?
6
22
30
48
72
Answer:
Step-by-step explanation:
Perimeter =100
the lengths of the sides are 5x+3x+30x+2x+10
5x+3x+30+2x+10=100
10x=100-40
10x=60
x=6
one side is 5x=30
one side 18+30=48
one side 2x+10=12+10=22
the longest side is 48
Longest side of triangle is 48 inches
Given information:
Perimeter of triangle = 100 inches
First side of triangle = 5x
Second side of triangle = 3x + 30
Third side of triangle = 2x + 10
Find:
Length in inches and longest side of the triangle
Computation:
Perimeter of triangle = Sum of all sides
So,
5x + (3x + 30) + (2x + 10) = 100
10x + 40 = 100
10x = 60
x = 10
So,
First side of triangle = 5x = 5(6)
First side of triangle = 30 inches
Second side of triangle = 3x + 30 = 3(6) + 30
Second side of triangle = 48 inches
Third side of triangle = 2x + 10 = 2(6) + 10
Third side of triangle = 22 inches
Longest side of triangle is 48 inches

In 2010, the government took out 6.2% of earnings for Social Security to a maximum taxable income of $106,800. For Medicare, 1.45% of earnings was paid. How much money would someone have to have earned in 2010 so that their payments into Medicare were equal to their payments into Social Security?
9514 1404 393
Answer:
$456,662
Step-by-step explanation:
The amount paid to Social Security is a maximum of ...
6.2% × $106,800 = 6,621.60
If we want an equal amount paid to Medicare, we want ...
1.45% × earnings = $6,621.60
earnings = $6,621.60/0.0145 ≈ $456,662
Someone would have to earn $456,662 so that their Social Security and Medicare payments were equal.

Given f(x) = -2x + 17; g(x) = -5x - 10. What is h(x) = f(x) – g(x)? *
(if you would like to answer all three that would be nice )
Answer:
Image provided.
Step-by-step explanation:
Question 1)
Given
f(x) = -2x+17
g(x) = -5x-10
To determine
h(x) = f(x) – g(x)
Using the equation
h(x) = f(x) – g(x)
substitute f(x) = -2x+17 and g(x) = -5x-10
= -2x+17 - (-5x-10)
= -2x+17 + 5x + 10
= 3x + 27
Thus,
h(x) = 3x + 27
Question 2)
Given
f(x) = 7x+6
g(x) = 6x+8
To determine
j(x) = f(x) + g(x)
Using the equation
j(x) = f(x) + g(x)
substitute f(x) = 7x+6 and g(x) = 6x+8
j(x) = 7x+6 + 6x+8
j(x) = 13x + 14
Thus,
j(x) = 13x + 14
