Answer:
See Below
Step-by-step explanation:
Initial cost = $52
Markup for operating expenses = 34%
$52 + 34% = $52*1.34 = $69.68
Markup for profit = 6%
69.68 + 6% = 69.68*1.06 = 73.86 (rounded)
a) The selling price is $73.86
b) The reduced price is:
$73.86 - $25 = $48.86
c) The percent of markdown:
25/73.86*100% = 33.85% (rounded)
d) The absolute loss:
$69.68 - $48.86 = $20.82
The local grocer is charging $17.50 for five pounds of hamburger. Determine total cost of hamburger based on the weight of the hamburger purchased.
Answer:

Step-by-step explanation:
17.50 divided by 5 is 3.5 so 1 pound is 3.5
For one binomial experiment, n1 = 75 binomial trials produced r1 = 30 successes. For a second independent binomial experiment, n2 = 100 binomial trials produced r2 = 50
successes. At the 5% level of significance, test the claim that the probabilities of success for the two binomial experiments differ.
(a) Compute the pooled probability of success for the two experiments. (Round your answer to three decimal places.)
(b)Compute the corresponding sample distribution value. (Test the difference p1 − p2. Do not use rounded values. Round your final answer to two decimal places.)
(c)Find the P-value of the sample test statistic. (Round your answer to four decimal places.)

Please Answer The Following Question: Write the rational approximation of straight pi correct to two decimal places, where straight pi almost equal to 3.14159265 space
[Note: begin mathsize 12px style straight pi end style is the ratio of a circle's circumference to its diameter.]
Answer:
Most people know Pi up to 2 decimal places (3.14) because you can always refer to the internet for those extra decimal places anytime you want.
Step-by-step explanation:
It's easy to create rational approximations for π. Every time you write down π to a few decimal places, that's a rational approximation.
Depending on the purpose of a calculation, π can be approximated by using fractions for ease of calculation. The most notable such approximations are 22⁄7 (relative error of about 4·10−4) and 355⁄113 (relative error of about 8·10−8).

Find the equation of the line passing through (4, 5) and parallel to
3x-2y=4.
[tex]\rule{50}{1}\large\blue\textsf{\textbf{\underline{Answer and how to solve:-}}}\rule{50}{1}[/tex]
First of all, We need to convert this equation from standard form (ax+by=c) into slope-intercept form (y=mx+b).
[tex]\rightarrow[/tex] First, add 2y on both sides:-
[tex]\Large\textsf{3x+2y=4}[/tex]
[tex]\rightarrow[/tex] Now, subtract 3x on both sides:-
[tex]\Large\textsf{2y=-3x+4}[/tex]
[tex]\rightarrow[/tex] Divide by 2 on both sides
[tex]\Large\text{$y=-\displaystyle\frac{3}{2}x +2$}[/tex]
[tex]\rule{300}{3}[/tex]
Now, let's find the equation of the line that's parallel to the given line.
Remember, if lines are parallel to each other, then their slope's the same.
So the slope of the line that's parallel to the line whose equation we just found, is
[tex]\Large\text{$-\displaystyle\frac{3}{2}$}[/tex]
Now let's write the equation in point-slope form:-
[tex]\hookrightarrow\sf{y-y_1=m(x-x_1)}[/tex]
Replace numbers with letters, as follows:-
[tex]\sf{y-5=-\displaystyle\frac{3}{2} (x-4)}[/tex]
The equation above is the equation in point-slope form.
Incase you need it converted to slope intercept form, refer to the steps below ~
Multiply -3/2 times x and -4:-
[tex]\hookrightarrow\sf{y-5=-\displaystyle\frac{3}{2} x-6}[/tex]
Now, Add 5 on both sides:-

Choose the conjecture that describes how to find the 6th term in the sequence 4, 20, 36, 52, ….
A)
Add 16 to 32.
B)
Add 32 to 52.
C)
Multiply 52 by 5.
D)
Multiply 52 by 9.
Answer:
B
Step-by-step explanation:
there is a common difference between consecutive terms in the sequence, that is
20 - 4 = 36 - 20 = 52 - 36 = 16
thus to obtain the next term in the sequence add 16 to the previous term
To obtain 2 terms distant then add 16 + 16 = 32
so 6th term = 52 + 32 = 84

To multiply 64 • 8.32, use the logarithmic equation:
1) log 72.32
2) log 64 + log 8.32
3) antilog 64 + antilog 8.32
4) (log 64)(log 8.32)
To multiply 64 • 8.32, use the logarithmic equation (2) log 64 + log 8.32
How to determine the equivalent equation?The product is given as:
64 * 8.32
As a general rule, the product of a and b can be calculated using:
a * b = antilog(log(a) +log(b))
This means that:
64 * 8.32 = antilog(log(64) +log(8.32))
Hence, we make use of the logarithmic equation (2) log 64 + log 8.32

PLEASE HELP!!!!!! IMA DESPRATE!!!!!!Determine whether f(x) = 2x3 − 6 is linear. If so, give the slope and y-intercept.
The slope of the cubic polynomial and it's y-intercept are respectively; f(1) = -4 and f(0) = -6
What is the slope of the equation?
We are given the equation;
f(x) = 2x³ - 6
Now, because the highest power of x is 3, it means that this is a cubic polynomial and not linear because it has a degree of 3
Thus, let us differentiate to get the slope;
f'(x) = 6x² - 6
At f'(x) = 0; x = 1
Thus, slope is;
f(1) = 2(1)³ - 6
f(1) = -4
y-intercept is f(x) at x = 0. Thus;
f(0) = 2(0³) - 6
f(0) = -6

What is the equation of the line that is perpendicular to -x+y=7 and passes through (-1,-1)?
a.-x+y=2
b.-x-y=2
c.x-y=2
d.-x-y=0
e. x+y=0
Answer:
[tex]-x - y = 2[/tex].
Step-by-step explanation:
If the slope of a line in a plane is [tex]m[/tex] and the [tex]y[/tex]-intercept of that line is [tex]b[/tex], the slope-intercept equation of that line would be [tex]y = m\, x + b[/tex].
Rearrange the equation of the given line [tex]-x + y = 7[/tex] in the slope-intercept form to find the slope of this line:
[tex]-x + y = 7[/tex].
[tex]x -x + y = x + 7[/tex].
[tex]y = x + 7[/tex].
Notice that in the slope-intercept equation of this given line, the coefficient of [tex]x[/tex] is [tex]1[/tex]. Thus, the slope of the given line would be [tex]m_{1} = 1[/tex].
Two lines in a plane are perpendicular to one another if the product of their slopes is [tex](-1)[/tex]. In other words, if [tex]m_{1}[/tex] and [tex]m_{2}[/tex] are the slopes of two lines perpendicular to each other, then [tex]m_{1}\, m_{2} = (-1)[/tex].
Since [tex]m_{1} = 1[/tex] for the given line, the slope of the line perpendicular to this given line would be:
[tex]m_{2} = (-1) / m_{1} = (-1) / 1 = -1[/tex].
If the slope of a line in a plane is [tex]m[/tex], and that line goes through the point [tex](x_{0},\, y_{0})[/tex], the equation of that line in point-slope form would be:
[tex]y - y_{0} = m\, (x - x_{0})[/tex].
The slope of the line in question is [tex]m = (-1)[/tex]. It is given that this line goes through the point [tex](-1,\, -1)[/tex], where [tex]x_{0} = (-1)[/tex] and [tex]y_{0} = (-1)[/tex]. Thus, the equation of this line in point-slope form would be:
[tex]y - y_{0} = m\, (x - x_{0})[/tex].
[tex]y - (-1) = (-1)\, (x - (-1))[/tex].
[tex]y + 1 = -(x + 1)[/tex].
Rearrange this equation to match the format of the choices:
[tex]y + 1 = -x - 1[/tex].
[tex]x + y = -2[/tex].
[tex]-x - y = 2[/tex].

Answer: See the table below
========================================================
Explanation:
The first task is to sort the values from largest to smallest.
Doing so gets us this list
57, 51, 48, 46, 45, 44, 43, 41, 40, 39, 39, 38, 37, 36, 36, 35, 35, 34, 33, 32, 31, 29, 29, 28, 24, 21, 19, 18, 13, 8
Next, we look for values that are between 56 and 60. That would be the single value of 57. This means we have 1 tally mark for the first row and the frequency is 1.
After that, we look for values between 51 and 55. That would be the single value of 51. Like the previous row, we'll have a single tally and a frequency of 1.
The 46-50 group will have the values 48 and 46 in it, so we have two tally marks and a frequency of 2 for this row.
This process is continued until all the values are accounted for. Effectively you are sorting the values into the proper bins.
You should end up with the table below. The fourth column is optional. It helps show where all of the values are sorted (to help confirm we have the correct tallies and frequencies).

Calculate the hollow conducting cylinder with an inner diameter a= 10 mm and outer diameter b= 18 mm. The height of the cylinder is 35 mm. Find the volume of cylinder.
Answer:

Step-by-step explanation:
If R is the outer radius and r the inner radius of a hollow cylinder of height h, then volume of cylinder = π (R² - r²)h

and r= 10/2 =5
Volume = π (9² - 5²) . 35 = π x 56 x 35 = 1960 π
