Answers
The probability for household with income under $75,000 is 54.5/100. the probability for household with income $50,000 or above is 72.8 /100, and the probability for household with income between $50,000 and (under) $150,000 is 64.5/100.
What is probability?
Probability describes potential. This area of mathematics examines how random events happen. The value might be between 0 and 1. Mathematicians have used probability to forecast the likelihood of certain events. In general, probability relates to how likely something is to happen. You can better understand the potential results of a random experiment by using this fundamental theory of probability, which also holds true for the probability distribution. To calculate the likelihood that an event will occur, we first need to know how many possible possibilities there are.
As given in the question,
Household with Income $50,000 are 27.2%
$50,000 - $75,000 are 27.3%
$75,000 - $150,000 are 37.2%
$150,000 or above are 8.3%
a) we have to find the probability for household with income under $75,000
So, Households having income under $75,000 are equal to:
(27.3 + 27.2)% = 54.5%
Therefore, probability = 54.5/100
b) we have to find the probability for household with income $50,000 or above,
So, household with income $50,000 or above are equal to:
(27.3 + 37.2 + 8.3)% = 72.8%
Therefore, probability = 72.8 /100
c) we have to find probability for household with income between $50,000 and (under) $150,000.
so, household with income between $50,000 and (under) $150,000 are equal to:
(27.3 + 37.2)% = 64.5%
Therefore, probability = 64.5/100
d) answer a can be interpret in percentage as 54.5%
answer b can be interpret in percentage as 72.8%
answer c can be interpret in percentage as 64.5%

A union voted on whether to go on strike 120 people vote the ratio of yes and no votes is 2:3 how many people vote no
Answers
Answer:

Step-by-step explanation:
This is a ratio and we can set it up as follows and solve for x:
[tex]\frac{2}{3} = \frac{x}{120}[/tex]
Multiply both sides by 120
80 = x
Divide 120 / 5 = 24
Then multiply the individual digits of ratio (2:3) by 24

Put these numbers together in a ratio, 48:72

Area of Rectangle=Length × Width
42 = 6 x b
b = 42/6
b = 8 in.
it is given that :
area of second painting = 28 square inches
and having same width as the first painting that is b = 8 in.
Now, calculating length second of painting using formula :

Find the vertical and horizontal lines that passes through the point (3,6).
Answers
We have to find the vertical and horizontal lines that passes through the point (3,6).
A vertical line will be defined as x = constant. If it passes trough a point (x,1,y1), the line will be defined as a x=x1, so the point (x1,y1) belongs to the line.
The same goes for horizontal lines, but in this case the line is defined as y = constant.
For a point (x1,y1), the horizontal line that pass through the point will be y = y1.
Then, for point (x,y)=(3,6), the vertical and horizontal lines as:
x=3 and y=6.
Answer:
Vertical line: x = 3
Horizontal line: y = 6.

First, let us evaluate the length of each side of the triangle using the distanec formula.

The price of a notebook has risen to $3.35 today. Yesterday's price was $3.10. Find the percentage increase. Round your answer to the nearest tenth of a percent.
Answers
The percent of increasing = amount of increasing/original amount x 100%
Since the price of the notebook on one day is $3.10
Since it is increased to $3.35
Then the amount of increasing = 3.35 - 3.10 = 0.25 dollars
Since the original price is 3.10
By using the rule above
[tex]\text{Percent}=\frac{0.25}{3.10}\times100[/tex]The percent of increasing = 8.064516%

4) At a fundraising event, there is a raffle. A total of 165people bought a raffle ticket. The ratio of losing ticketsto winning tickets is 12:3. How many people wonsomething in the raffle?
Answers
In order to determine the number of people which won something, it is necessary to write the following system of equations:
x + y = 165
y/x = 12/3
x is the people won and y the people lost.
The first equation represents tha total number of people in the event.
The second equation represents the ratio of losing tickets to winning people.
First, solve the second equation for y, and then replace the expression for y into the first equation:
y = 12/3 x
x + 12/3 x = 165
next, solve the last equation for x:
(3+12)/3 x = 165
15/3 x = 165
5x = 165
x = 165/5
x = 33
x is the number of people who won something in the event.
Hence, the number of people was 33

The state unemployment taxes worth $7977.726 deducted from Suzie's salary.
The FUTA taxes worth $938.556 deducted from Suzie's salary.
What is tax?
A tax is a mandatory financial charge or other sort of levy placed on a taxpayer (an individual or legal entity) by an administrative body to pay for certain public expenditures and administrative costs (regional, local, or national).
It is given in the question that weekly salary of Suzie is $3,000.
we know that, there are 365 days in a year and 7 days in a week.
Therefore, weeks in a year = 365/7 = 52.142
Yearly salary is equal weekly salary times weeks in a year.
Yearly Salary = (3000)52.142
yearly Salary = $156,426
Social security taxes are 6.20%
So, 6.20% of 156,426 is $9,698.412
Therefore, The Westway deduct $9,698.412 for Suzie's social security for the year.
Medicare taxes are 1.45%
So, 1.45% of 156,426 is $2268.177
Therefore, The Westway deduct $2268.177 for Suzie's Medicare for the year.
The state unemployment taxes are 5.10%
So, 5.10% of 156,426 is $7977.726
Therefore, The state unemployment taxes worth $7977.726 deducted from Suzie's salary.
The FUTA taxes are 0.60%
So, 0.60% of 156,426 is $938.556
Therefore, The FUTA taxes worth $938.556 deducted from Suzie's salary.

Use the "Cannot bewritten" button, if applicable.The equation of the line in slope-intercept form:
Answers
Answer: y = -4x - 21 OR 4x + y = -21
The given line is 4x + y = -5
Given point = (-4, -5)
Step 1: find the slope of the line
The slope intercept form of equation is given as
y = mx + b
Re -arrange the above equation to slope - intercept form
4x + y = -5
Isolate y
y = -5 - 4x
y = -4x - 5, where m = -4
Since the point is parallel to the equation
Therefore, m1 = m2
m2 = -4
For a given point
(y - y1) = m(x - x1)
Let x1 = -4, and y1 = -5
[(y - (-5)] = -4[(x - (-4)]
[y + 5] = -4[x + 4]
Open the parentheses
y + 5 = -4x - 16
y = -4x - 16 - 5
y = -4x - 21
The equation is y = -4x - 21 or 4x + y = -21
