The histogram for these data is given at the end of the answer.
What is an histogram?An histogram is a graph that shows the number of times each element of x was observed.
For this problem, there are 5 classes with a range of 30, as 59.5 - 29.5 = 30, hence the class width is of:
30/5 = 6.
From the data-set, we have that:
There are 7 values between 29.5 and 35.5.There are 0 values between 35.5 and 41.5.There are 2 values between 41.5 and 47.5.There are 4 values between 47.5 and 53.5.There are 4 values between 53.5 and 59.5.Considering this, the histogram is given at the end of the answer.

What formula would you use to find 50 is what percent of 20?
a) p = rb
b) r = p/b
c) i = prt
d) b = p/r
Answers
We would use r = p/b formula to find 50 is what percent of 20.
The correct answer is an option (b)
For given question,
we need to find the formula which we use to find 50 is what percent of 20
We make the assumption that 20 is 100% since it is our output value.
Let the value we seek be m.
So, 100 % = 20 ...............(1)
m % = 50 ..............(2)
By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
[tex]\frac{100\%}{m\%}=\frac{2}{5}[/tex]
So, m = 250%
This means, 50 is 250% of 20
The formula PERCENTAGE p = rb – The result obtained when a number is multiplied by a percent.
The formula BASE ( b = p/r) – The whole in a problem. The amount you are taking a percent of.
The formula RATE (r = p/b) – The ratio of amount to the base. It is written as a percent.
Therefore, we would use r = p/b formula to find 50 is what percent of 20.
The correct answer is an option (b)

A. First move the decimal point to the right to get a number that is
greater than or equal to 1 but less than 10.
0.0043 The decimal point moves 3
places to the right.
Remove the extra zeros to get the first factor:
B. Since 0.0043 is less than 1, you moved the decimal point to the right,
so the exponent in the power of 10 will be negative.
-3
0.0043 = 4.3
X 10
Answers
the thickness in scientific notation is:
4.3* 10⁻³ inches
How to write the thickness in scientific notation?
Here we know that the thickness of a dollar bill is 0.0043 inches.
Now, scientific notation refers to the notation where we have a single digit at the left of the decimal point, and the order of the number is defined by a factor of a power of 10.
To write our number in scientific notation we need to count the number of zeros that we have before the first non-zero decimal, and we can see that it is equal to 3.
Then we can move all the digits 3 units to the left, and add a factor 10⁻³ to correct that, then we will get:
0.0043 = 4.3* 10⁻³
From this, we conclude that the thickness in scientific notation is:
4.3* 10⁻³ inches

A rectangular sheet of tin measures 20 inches by 12 inches. suppose you cut a square out of each corner and fold up the sides to make an open-topped box. what size square should you cut out to maximize the box's volume? show all work to earn credit.
Answers
The volume of the box is maximized when a 6 x 6 inch or 10 x 10 inch square is cut from the corners of the rectangular sheet.
Volume of rectangle:
The volume of an object is the amount of space occupied by the object or shape, which is in three-dimensional space. It is usually measured in terms of cubic units.
The formula for Volume of the rectangle is
V = l x b x h
where
l represents the length
b represents the breadth
h represents the height.
Given,
A rectangular sheet of tin measures 20 inches by 12 inches. suppose you cut a square out of each corner and fold up the sides to make an open-topped box.
Here we need to find the volume of the box is maximized when a square is cut from the corners of the rectangular sheet.
Here we have the following values:
h = x
l = 20 - 2x
b = 12 - 2x.
Here we have to subtract two times of x value because in the question they said that we have to cut a square from it.
Apply the values on the volume formula then we get,
=> V = (20 - 2x) x (12 - 2x) x (x)
=> V = [240 - 40x - 24x + 4x²] x (x)
=> V = [240x - 64x² + 4x³]
Now differentiate:
=> V' = 240 - 64x + 4x²
Simplify and order the equation,
Then we get,
=> V' = x² - 16x + 60
When we factorize the equation then we get,
=> V' = x² - 6x - 10x + 60
Take the common term out of it,
=> V' = x (x-6) -10(x -6)
Therefore, the value of x is, either 6 or 10.
Now you need to look at your solutions.
At x=6, the volume is,
=> V = (20 - 2(6)) x (12 - 2(6)) x (6)
=> V = (20 - 12) x (12 - 12) x 6
=> V = 8 x 0 x 6
=> V = 0
our corner squares devour the entire piece of cardboard and you are left with zero volume; so that solution is a minimum.
Now at the value of x = 10,
The volume is
=> V = (20 - 2(10) x (12 - 2(10)) x (10)
=> V = (20 - 20) x (12 - 20) x 10
=> V = 0 x (-8) x 10
=> V = 0
So, in both cases we have 0 as minimum volume. So, we can take any one of the value to get the maximum out of it.

the function f(x) is shown. the function g(x)= 2x - 6 compare slopes
Answers
Answer: The slope of f(x) is less than the slope of g(x) because the slope of f(x) is -3
Step-by-step explanation:
Define slope?
The slope of a line is the ratio of the amount that y increases as x increases some amount. Slope tells you how steep a line is, or how much y increases as x increases. The slope is constant (the same) anywhere on the line.
We can write:
m=(y2-y1) / (x2-x1)
If,
g(x) = 2x - 6
The slope of g(x), m = 2
Let, x1=0
y1=2
x2=-1
Y2=1
So, we take (x1, y1) and (x2, y2) Then consider (0, 2) and (-1, 1)
Solve it:
Replace with x1, y1 and x2, y2
m = [1-(-2)/(-1)]
m=[(1+2) /(-1) ]
m=3/(-1)
m=-3
Thus, the slope of f(x) is less than the slope of g(x) because the slope of f(x) is -3.

Say that you own property with a market price of $74,000. the state tax assessors have given it an assessed value of 48% of that amount. if your state’s property tax rate is 0.031, how much do you owe in property tax, to the nearest dollar? a. $1,101 b. $2,294 c. $35,520 d. $1,193 please select the best answer from the choices provided a b c d
Answers
Option a. $1101 is the amount one owes in property tax
The market price of the property = $74000
The assessed value of the property as per the state tax assessors= 48%
So, assessed value in terms of dollars = (48/100)*74000 = $35520
Property tax is calculated on the assessed value of the property. Therefore we will calculate the property tax as follows:
Property tax rate in the state= 3.1%
So, property tax on the owned property will be = (3.1/100)*35520 = 1101.12 or 1101
Therefore, option a. $1101 is the correct answer for the given question
Hence, one needs to pay $1101 in property tax to the state

• Both customers paid the same amount per hot wing.
How much does one hot wing cost at this restaurant in dollars and cents?
Record your answer in the boxes below. Be sure to use the correct place value.
+/-
Answers
Explanation:
We’ll solve this with a set of equations since the price per wing is fixed and they paid the sam amount at the restaurant. Let x represent the cost of 1 wing.
8x + 4.00 = 10x + 2.80
4.00 = 2x + 2.80
1.20 = 2x
0.60 = x
So, we have found that one wing cost $0.60.

Given,
In 2008, the centers for disease control and prevention reported the average human life span in the united states as 76.8 years for men and 81.6 years for women.
Here we need to calculate how much longer, on average, u.s. women live than men in seconds.
Here we know that,
Average life span for men = 76.8 years
Average life span for women = 81.6 years.
So, the women lived
=> 81.6 - 76.8
=> 4.8 years.
So, the average women lived 4.8 years more than the man.
Now we have to convert it into seconds,
We know that,
