A bike shop marks up a hybrid bike from $200 to $330 and discounts a road bike from 330 to 200 by what you percent is the road bike discounted . I need the answer ASAP
Answer:
39.39%
Step-by-step explanation:
There's a nice little formula that is used to find percentage change which works regardless of if it's an increase or decrease.
[tex]Percent~Change = |\frac{New~Value~-~Original~Value}{Original~Value}| * 100[/tex]
1 - Understanding the equation
The '|'s which are surrounding the fraction are absolute value symbols in mathematics,
Absolute value means the positive value of anything inside
Examples:
| -8 | = 8
| 8 | = 8
and
| -2 | = 2
| 2 | = 2
the * 100 means you multiply (the * symbol means multiply) by 100.
We do this to get it into a percent.
3 - Assign numbers to the values from our equation
Original Value (What it changed from): 330
New Value (What it changed to): 200
3 - Plug in our values into our variables from our equation[tex]Percent~Change = |\frac{200-330}{330}| * 100 = |\frac{-130}{330}| = = |-0.39...| * 100 = 0.3939... *100 =[/tex]
Our percent change is 39.39%, and with our percent in which is discounted being the same, we have our answer.
Hope this helps :)

The perimeter of the marked polygon is 26 units.
What is a perimeter?Perimeter is the distance around the outside of a shape.
Given is a polygon, ABCDEF,
Using the distance formula, we have,
(P, Q) = √ (x2 – x1)² + (y2 – y1)².
AB = 3 units
BC = 4 units
CD = 3 units
DE = 7 units
EF = 6 units
FA = 3 units
Perimeter = AB+BC+CD+DE+EF+FA = 3+4+3+7+6+3 = 26 units.
Hence, The perimeter of the marked polygon is 26 units.

Answer:
we need to divide 8.25 by 6 in order to get like 1.375 chapters a day
Step-by-step explanation:
plz mark brainliest i answered first
Answer:
11/8 chapters/day
Step-by-step explanation:
This is a "rate" problem. Divide 8.25 chapters by 6 days:
8.25 chapters
reading rate: ------------------------
6 days
Rewriting this as 8 1/4 chapters / 6 days makes the arithmetic a bit easier.
We then have 33/4 chapters / 6 days, or 33/24 chapters / day.
This reduces to 11/8 chapters/day.

he probability that an individual has 20-20 vision is 0.13. In a class of 24 students, what is the probability of finding five people with 20-20 vision
Answer: 0.111947
Step-by-step explanation:
Let x be a binomial variable that represents the number of people with 20-20 vision.
Given: The probability that an individual has 20-20 vision: p= 0.13
Sample size : n= 24
Binomial probability distribution formula:
[tex]P(X=x)=^nC_xp^x(1-p)^{n-x}[/tex]
The probability of finding five people with 20-20 vision :
[tex]P(X=5)=\ ^{24}C_5(0.13)^5(1-0.13)^{24-5}\\\\=\dfrac{24!}{5!19!}(0.13)^5(0.87)^{19}\\\\=0.111946975387\approx0.111947[/tex]
Hence, the required probability = 0.111947
The probability of finding five people with 20-20 vision is 0.0461.
Binomial Probability:The formula for the Binomial Probability is,
[tex]P(X = x) =(\frac{n!}{x!(n-x)!} )\times p^x \times (1-p)^{n-x}[/tex]
Given that,
[tex]p = 0.13\\1 - p = 0.87\\n = 72\\x = 5[/tex]
Substituting the given values into the above formula we get,
[tex]P(X = x) =(\frac{n!}{x!(n-x)!} )\times p^x \times (1-p)^{n-x}\\P(X=5)=(\frac{72!}{5!(72-5)!} ) (0.13)^5(0.87)^{72-5}\\P(X=5)=0.0461[/tex]

Arnold is planning on painting a mural. Before painting the mural, Arnold painted the picture on a paper that is 5 inches wide and 11 inches tall. Arnold is using a scale in which 12 inch represents 1 foot to paint the mural.
How wide and tall will the actual mural be?
Drag and drop the height and width of the actual mural into the boxes.
Mural Height Mural Width
2.5 ft5.5 ft10 ft22 ft
Answer:
0.42 ft
0.92 ft
Step-by-step explanation:
Width of mural on painting = 5 inches
Height of mural on painting = 11 inches
12 inches of the painting represents 1 foot of the mural
1 inch of the painting represenets [tex]\dfrac{1}{12}[/tex] foot of the mural.
[tex]5\ \text{inches}=5\times \dfrac{1}{12}=0.42\ \text{ft}[/tex]
[tex]11\ \text{inches}=11\times\dfrac{1}{12}=0.92\ \text{ft}[/tex]
The width of the mural is 0.42 ft and height of the mural is 0.92 ft.
The height and width of the actual mural into the boxes is 0.92 ft and 0.42 ft.
Calculation of the height and width:Since
Arnold painted the picture on a paper that is 5 inches wide and 11 inches tall. Arnold is using a scale in which 12 inch represents 1 foot to paint the mural.
So here the width should be 5 of 1 by 12 should be 0.42 feet
And, the height should be 11 of 1 by 12 should be 0.92 ft.
Hence, The height and width of the actual mural into the boxes is 0.92 ft and 0.42 ft.
