The wholesale price for a dozen pairs of socks is $4.30. The retail price for the same dozen pairs of socks is $9.25. What is the mark-up the retailer used? Write your answer as a complete sentence.
Answer:
the mark up used by the retailer is 115.12% of the wholesale price
Step-by-step explanation:
Mark-up is the percentage increase of the retail price over the wholesale price
Mark-up = (difference between retail and whole sale price / retail price ) x 100
difference between retail and whole sale price = $9.25 - $4.30 = $4.95
(4.95 / 4.3) x 100 = 115.12%.

Surface area of a pyramid 9ft and 6ft sqaurd
find the length of each side of the triangle. check that the perimiter is equal to 20 inches
Answer is x=8
Step-by-step explanation:
add up all the sides and set it equal to 20
add all the x's and constants
subtract the constant from both sides
then multiply by the reciprocal of the fraction from both sides and you'll get x

The standard deviations of four data sets are shown in the table below. Which
of the data sets is the most spread out?
Data set
Standard deviation
Data set A
6.06
Data set B
4.88
Data set C
5.21
Data set D
3.39
A. Data set B
B. Data set D
C. Data set C
D. Data set A
Answer: Data set A
Step-by-step explanation: It has the most
The largest deviation for this case is from the dataset C so then the answer would be Data set C.
How is standard deviation calculated?Suppose that the considered data set is
Then, its standard deviation is the positive square root of the variance of this data set.
A variance of data set is the sum of squared differences of the data values from its mean to the total count of data values.
Thus, we get:
[tex]\sigma = \sqrt{\dfrac{1}{n} \sum_{i=1}^{n} (x_i-\overline{x})^2[/tex]
And for this case we have the deviations for each dataset are given by:
[tex]s_a = 5.21\\\\s_b =4.88\\\\s_c = 6.06\\\\s_d = 3.39\\[/tex]
We need to remember that the deviation is a measure of dispersion.
For this case, if the deviation is larger then we have more spread out the distribution of interest.
And largest deviation for this case is from the dataset C so then the answer would be:
Thus, the correct answer is D. Data set C.

Find x and show work
Step-by-step explanation:
58 +38 = 96 degree
so we do 180 - 96 = 84 degree valur of x for one triangle
so opposite side angke x will be 96
so again we do 96 +15 = 111 degree
180 - 111 = 69 degree

1. a circle has a circumfrance 88cm find its radius
2.a sector with angle 45 degrees has ab arc length 44cm find it radius and perimeter speratly
pls answer asap i will give u the brainliest
Step-by-step explanation:
Number 1
Circumference = 88cm
Circumference = 2πr
2πr = 88
πr = 88/2
πr = 44
22r/7 = 44
22r = (44 × 7)
r = (44 × 7)/22
r = 2 × 7
r = 14cm
Number 2
Length of arc = 44cm
Angle = 45°
L = ∅/360 × 2πr
44 = 45/360 × 2πr
44 = ⅛ × 2πr
44 = ¼ × πr
πr = 44 × 4
22r/7 = (44 × 4)
22r = (44 × 4 × 7)
r = (44 × 4 × 7)/22
r = 2 × 4 × 7
r = 2 × 28
r = 56cm
Perimeter = L + 2r
P = 44cm + 2(56cm)
P = 44cm + 112cm
P = 156cm

The sign shows that any number that is equal to, or more than, 36 is a valid answer. It can't be 3 because 3 x 9 is 27, and 27 is less than 36, so that wouldn't be true. 4 x 9 is 36, and 36 = 36, so that would be true, and obvoiusly all the other numbers that are over 4, when multiplied by 9, will equal more than 36, so they are all correct, except for the 3 and none answers.

The amount y (in dollars) that you earn by working x hours is represented by the equation y = 9x. A) What is the slope? B) What does the slope mean? Interpret! C) How much money would you make if you worked 40 hours?
Answer:
360 dollars
Step-by-step explanation:
Equation;
y = 9x
A) What is the slope?
The slope in an equation is the coefficient of the x variable. In this question, the slope is 9.
B) What does the slope mean? Interpret!
The slope shows the relationship between the x and y values.
This means that for every single unit change of x, y changes by 9 times.
C) How much money would you make if you worked 40 hours?
x = working hours
y = Amount
y = 9 (40) = 360 dollars
