Answer:
The median of this data set is 1
Step-by-step explanation:
1) First sort the list of all the data set from the smallest to the largest
so we have (0,0,0,0,0,0,0,0,1,1,1,1,2,2,2,2,2,3,3,5,10)
2) Find the elements in the middle of the list
(0,0,0,0,0,0,0,0,1,1,1,1,2,2,2,2,2,3,3,5,10)
When you find an unique number your work is done, but when this happens the median is the average of the two elements in the middle of the sorted list
Hence the median is 1
The scale on a map of Virginia shows that 1 inch represents 15 miles. The actual distance from Richmond, VA, to Washington, D.C., is 110 miles. On the map, how many inches are between the two cities? Enter your answer as a mixed number with the fraction in simplest form.
The distance on the map is __ in.
Answer:
The answer to your question is: 7 1/3 inches
Step-by-step explanation:
Data
1 inch --------- 15 miles
Distance from Richmond to Washington = 110 miles
Use a rule of three to solve it
1 inch ----------------- 15 miles
x -------------------- 110 miles
x = 110x 1 /15
x = 110 / 15 simplify dividing by 5
x = 22/3
Convert it to a mix number
22/3 = 7 1/3 inches
Final answer:
On the map, 7.6 inches are between the two cities
Explanation:
To find out how many inches are between two cities on a map given the scale and the actual distance. The scale here is that 1 inch represents 15 miles. Therefore, for an actual distance of 110 miles, we simply divide the actual distance by the scale factor to obtain the distance on the map.
By setting up the proportion:
1 inch / 15 miles = x inches / 110 miles, we cross-multiply and solve for x,
which is the number of inches on the map. The calculation would be:
(1 inch / 15 miles) * 110 miles = 110 inches / 15 = 7 3/5 inches or 7.6 inches.

Final answer:
The answer calculates the price per quart of laundry detergent from a 3-gallon container and provides estimated costs for 40 oz. and 90 oz. sizes. All calculations are based on the given information and formula.
Explanation:
Price of 3-gallon container: $20.76
Price per quart: $20.76 / 12 quarts = $1.73 per quart
If the detergent were sold in a 40 oz. size: Estimated cost = $1.73 x 3.33 = $5.76
If the detergent were sold in a 90 oz. size: Estimated cost = $1.73 x 7.5 = $12.98
Sarah begins at a negative position along the x-axis. Sarah moves in the positive x-direction, turns around and then moves in the negative x-direction. Her final position is more negative that her initial position. Is the magnitude of Sarah's displacement greater than, less than, or equal to the distance she travels?
Answer:
he magnitude of Sarah's displacement is less than the distance she travels
Step-by-step explanation:
Hi!
The magnitude of her displacement is just the difference between her final and initial state, however the distance she traveled is two times the distance she moved in the positive x-direction until she turned around, since she had to move back, plus her displacement.
So:
[tex]displacement = |x_{final} -x_{initial}| \\distanceTraveled = 2|x_{return}-x_{initial}| + displacement\\[/tex]
Since all the terms are positive:
[tex]x_{displacement}<x_{traveled}[/tex]

A test consists of 10 true/false questions. To pass the test a student must answer at least 88 questions correctly. If a student guesses on each question, what is the probability that the student will pass the test? Round to three decimal places.
Answer:
The probability that the student is going to pass the test is 0.0545
Step-by-step explanation:
The variable that says the number of correct questions follows a Binomial distribution, because there are n identical and independent events with a probability p of success and a probability 1-p of fail. So, the probability of get x questions correct is:
[tex]P(x)=\frac{n!}{x!(n-x)!} *p^{x} *(1-p)^{n-x}[/tex]
Where n is equal to 10 questions and p is the probability of get a correct answers, so p is equal to 1/2
Then, if the student pass the test with at least 8 questions correct, the probability P of that is:
P = P(8) + P(9) + P(10)
[tex]P=(\frac{10!}{8!(10-8)!}*0.5^{8}*(0.5)^{10-8})+(\frac{10!}{9!(10-9)!} *0.5^{9} *(0.5)^{10-9})+(\frac{10!}{10!(10-10)!} *0.5^{10} *(0.5)^{10-10})[/tex]
P = 0.0439 + 0.0097 + 0.0009
P = 0.0545
if (fx)=5x, what is f^-1(x)
Answer:
x/5
Step-by-step explanation:
To get the inverse function you need to leave the x alone and then switch variables ( f(x) = y)
f(x) = 5x
y = 5x
y/5 = x
Now that x is alone you switch the x for y and the y for x and you get:
x/5 = y
And this new y is the inverse function of f(x) ( f^-1(x))
f^-1(x) = x/5
Jessica wants to buy a new team jacket that costs $35. If Jessica saves $5 a week for 4 weeks and $4 a week for 3 weeks, will she have enough money to buy the team jacket? Explain
No, Jessica he will not have enough to buy the jacket. She would have saved $32, not $35.
What is a system of equations?A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
Lets x represent the number of weeks it will take to save enough money. If she saves $11 each week, then in x weeks she will save 11x dollars.
Also, Add this to the 107 she has already saved, and at the end of 11 weeks she will have 11x + 107 dollars.
We want the amount saved to be equal to the price of the bike, so our equation;
11x + 107 = 173
Now we solve the equation.
Subtract 107 from both sides ;
11x = 66
Divide both sides by 11;
x = 6

Square EFGH stretches vertically by a factor of 2.5 to create rectangle E′F′G′H′. The square stretches with respect to the x-axis. If point H is located at (-2, 0), what are the coordinates of H′ ? A. (-5, 0) B. (-2, 0) C. (0.5, 0) D. (-2, 2.5)
Answer:
The coordinates of point H' are (-2 , 0) ⇒ answer B
Step-by-step explanation:
* Lets revise the vertical stretch
- A vertical stretching is the stretching of the graph away from the
x-axis
- If k > 1, then the graph of y = k • f(x) is the graph of f(x) vertically
stretched by multiplying each of its y-coordinates by k
* Lets solve the problem
- Square EFGH stretches vertically by a factor of 2.5 to create
rectangle E′F′G′H′
∴ k = 2.5
- The square stretches with respect to the x-axis
∴ The square stretches vertically
∴ The y-coordinates of each vertex of the square EFGH are
multiplied by 2.5 to get the vertices of the rectangle E'F'G'H'
∵ Point H located at (-2 , 0)
∵ The image of point (x , y) after stretched vertically by k is (x , ky)
∴ Point H' located at (-2 , 0 × 2.5) ⇒ (-2 , 0)
∴ The coordinates of point H' are (-2 , 0)
∴ Point H' located at (-2 , 0)

Machine A produces 100 parts twice as fast as Machine B does. Machine B produces 100 parts in 40 minutes. If each machine produces parts at a constant rate, how many parts does Machine A produce in 6 minutes?
Answer:
30 parts
Step-by-step explanation:
We are given that machine produces 100 parts twice as fast as machine B does.
Machine produces 100 parts in 40 minutes.
We have to find number of parts produces by machine A in 6 minutes.
According to question
Machine A takes time to produce 100 parts =[tex]\frac{40}{2}=20 minutes[/tex]
Machine A and machine B produces parts at constant rate.
Machine A produces parts at the rate=[tex]\frac{100}{20}=5 parts /minute[/tex]
In one minute,Machine A produces =5 parts
In 6 minutes , machine B produces =[tex]5\times 6=30[/tex] parts

You are driving home from school steadily at 95 km/h for 180 km. It then begins to rain and you slow to 65 km/h. You arrive home after driving 4.5 h. (a) How far is your hometown from school? (b) What was your average speed?
Answer:
(a) 349.34
(b) 77.63 km/h
Step-by-step explanation:
Distance you covered before it rain S = 180 km
Speed v = 95/km
Time taken to cover 180 km = [tex]\frac{S}{v}[/tex]
= [tex]\frac{180}{95}[/tex]
= 1.89473 hrs.
Total time to cover the distance between school to home T = 4.5 hrs.
Remaining time t = T - t
= 4.5 - 1.89473
= 2.60527 h.
Velocity after travel 180 km. v' = 65 km/h
Distance traveled in this velocity S' = v'(t)
= 2.60527 × 65
= 169.34 km
(a) distance of hometown from school = 169.34 + 180 = 349.34 km.
(b) Your average speed V = [tex]\frac{S}{T}[/tex]
= [tex]\frac{349.34}{4.5}[/tex]

Order the function from the least steep slope to the steepest slope.
The functions ordered from the least steep slope to the steepest slope are: logarithmic (log(x)), linear (x), quadratic (x²), exponential (eˣ), and cubic (x³).
Explanation:To compare the steepness of the slopes for different types of functions, we consider the growth or decay rates of each function. The order is determined by the behavior of the functions as x increases.
1. Logarithmic function (log(x)): It grows slowly and approaches infinity as x increases, making it the least steep slope.
2. Linear function (x): It has a constant slope, making it steeper than logarithmic but less steep than quadratic, exponential, and cubic functions.
3. Quadratic function (x²): It increases faster than linear but slower than exponential and cubic functions.
4. Exponential function (eˣ): It grows at an increasing rate, making it steeper than quadratic but less steep than cubic.
5. Cubic function (x³): It has the steepest slope as x increases, making it the most rapidly increasing function.
This order is based on the general behavior of each function type and their rates of growth or decay. Understanding the characteristics of these functions helps in comparing and ordering them in terms of steepness.

Have to bake a lot of brownies to sell! You have plenty of flour, cocoa, milk, and oil, but you only have 6 1/2 sticks of butter. You need to know how many batches of brownies you can bake, based on your limited amount of butter. You can cook partial batches in order to use up every bit of butter, which will also help you to bake the most brownies possible. Each batch needs 3/4 of a stick of butter.
Answer: 8 + 2/3 batches of brownies you can bake.
Step-by-step explanation:
6 1/2 butter = 6 + 1/2 = (2·6 + 1)/2 = 13/2 sticks of butter, we have this
Since we have 13/2 sticks of butter and each batch of brownies needs 3/4 of a stick of butter, we have to divide the amount of butter we have between the amount of butter we use to bake a batch of brownies.
13/2 butter ÷ 3/4 butter/batch = 13·4/2·3 batches = 52/6 batches = 8 + 2/3 batches
Answer: 8 + 2/3 batches of brownies you can bake.
[tex]\textit{\textbf{Spymore}}[/tex]
By dividing the total amount of butter (13/2 sticks) by the amount required per batch (3/4 stick), we find that it's possible to make 8 full batches of brownies with 6 1/2 sticks of butter, with some butter left over.
To determine how many batches of brownies you can bake with 6 1/2 sticks of butter, you have to divide the total amount of butter you have by the amount required for one batch. Since each batch requires 3/4 stick of butter, you calculate as follows:
Total sticks of butter: 6 1/2
Required per batch: 3/4
Now convert 6 1/2 to an improper fraction: 6 1/2 = 13/2.
Next, calculate the number of batches by dividing the total butter by the butter per batch:
Number of batches = (13/2) / (3/4) = (13/2) * (4/3) = 52/6
When you simplify 52/6, you get 8 with a remainder, meaning you can make 8 full batches of brownies, and you will have some butter left over.

A gym charges a $25 sign-up fee plus $25 per month. You have a $200 gift card for the gym. When does the total spent on your gym membership exceed the amount of your gift card?
Answer:
After 7 months
Step-by-step explanation:
DATA:
⇒ Sign-up fee = $25
⇒ Monthly fee = $25
⇒ Number of months = y
⇒ Gift card = $200
Form an equation to calculate when the total spent on gym would exceed the amount of the gift card
Sign-up fee + (monthly fee x number of months) = Gift card amount
25 + 25y = 200
25y = 200-25
25y = 175
y = 7
Therefore, the total spent on your gym membership exceeds the amount of your gift card after 7 months.

3.Cash box contain bill of $1 is equals to 10 and bill of $5 is equals to 7.
4. Raisins is equals to 2.2 pounds and nuts is equals to 7.8 pounds for the trail mix.
What is equation?
" Equation is defined as the relation between the variables using sign of equality."
What is percentage?" Percentage is defined as the hundredth part of the given number."
According to the question,
1. 'x' represents the number
As per given condition,
x = 408% of 568
⇒ [tex]x= \frac{408}{100} (568)[/tex]
⇒ [tex]x = 2317.44[/tex]
Therefore, the number which is 408% of 568 is equals to 2317.44.
2. Total population of Detroit = 950,000
Population after 10 years = 712,500
Decrease in population = 950,000 - 712,500
= 237,500
Total percentage decrease in population = [tex]\frac{237500}{950,000}(100)[/tex]
= 25%
Therefore, total decrease in percentage of the population of Detroit is equals to 25%.
3. 'x' represents the bill of $1
'y' represents the bill of $5
As per the condition given equation we have,
$1x + $5y = $45 ______(1)
x = y + 3 ______(2)
Substitute the value of equation (2) in (1) we get,
[tex]1(y + 3) + 5y = 45\\\\\implies 6y = 45-3\\\\\implies y \frac{42}{6} \\\\\implies y = 7[/tex]
Substitute the value y in (2) we get,
[tex]x= 7 + 3\\\\\implies x =10[/tex]
Therefore , cash box contain bill of $1 is equals to 10 and bill of $5 is equals to 7.
4. 'x' represents the pounds of raisins
'10- x ' represents the pounds of nuts
Cost of trail mix from raisins and nuts per pound = $6.96
Therefore,
Cost of 10 pounds of trail mix of raisins and nuts = $(6.96 ×10)
= $69.6
Cost per pound of raisins = $3.45
Cost per pound of nuts = $7.95
Equation formed as per given condition we get,
[tex]3.45x + 7.95(10-x) = 69.6\\\\\implies 3.45x + 79.5 -7.95x = 69.6\\\\\implies -4.5x = 69.6 - 79.5\\\\\implies-4.5x= -9.9\\\\\implies x =\frac{9.9}{4.5}\\ \\\implies x = 2.2 pounds[/tex]
Pounds of raisins = 2.2pounds
Pounds of nuts = 10 - 2.2
= 7.8 pounds
Therefore, pounds of raisins is equals to 2.2 and pounds of nuts is equals to 7.8 for the trail mix.
Hence, As per the given conditions we have
1. Number which is 408% of 568 is equals to 2317.44 ( nearest hundredth).

The given function : [tex]f(x)=x^2+2x-3[/tex]
Using completing the squares, we have
[tex]f(x)=x^2+2x+1-1-3[/tex] [∵ [tex](x+1)^2=x^2+2x+1[/tex]]
[tex]f(x)=(x+1)^2-4[/tex] (1)
Comparing (1) to the standard vertex form [tex]f(x)=(x-h)^2+k[/tex] , the vertex of function is at (h,k)=(-1,-4)
For x-intercept, put f(x)=0 in (1), we get
[tex]0=(x+1)^2-4\\\\\Rightarrow\ (x+1)^2=4[/tex]
Square root on both sides, we get
[tex]x+1=\pm2\\\\x+1=-2\ or\ \ x+1=2\\\\=x=-3\ \ or\ x=1[/tex]
∴ x intercepts : x= (-3,0) and (1,0)
For y-intercept put x=0 in (1), we get

Suppose your state lottery has an expected value of
−34%.
If you spend $40 per month on lottery tickets, how much money would you be expected to lose in an average year?
We can expect to lose $
.
Final answer:
With an expected value of −34% for the state lottery and monthly spending of $40 on tickets, a person can expect to lose $13.60 monthly or $163.20 annually.
Explanation:
If the expected value of playing the state lottery is −34%, and a person spends $40 per month on lottery tickets, we can calculate the expected annual loss as follows:
Firstly, an expected value of −34% means that on average, for every dollar spent, you would expect to lose 34 cents. So for $40 spent in one month, the expected loss would be 34% of $40, which equals $13.60.
Next, we can find the expected loss for a year by multiplying the monthly loss by the number of months in a year:
Monthly expected loss: 0.34 × $40 = $13.60Annual expected loss: $13.60 × 12 months = $163.20Therefore, on average, you can expect to lose $163.20 per year if you continue spending $40 on lottery tickets every month.

The area of a triangle is given by the
formula A = 1/2bh Solve this for h.
Answer:
h = [tex]\frac{2A}{b}[/tex]
Step-by-step explanation:
Given
A = [tex]\frac{1}{2}[/tex] bh
Multiply both sides by 2 to clear the fraction
2A = bh ( isolate h by dividing both sides by b )
h = [tex]\frac{2A}{b}[/tex]
Answer: h = 2a/b

Simplify: (7a − 9c) − (−12a − 33c) − (−21a + 10c)
Answer:
The answer is 40a+14c
Step-by-step explanation:
Step 1: Open the brackets
7a-9c+12a+33c+21a-10c
Step 2: Group all the like terms
Like terms are terms with similar variables, for example;
(7a, 12a, 21a) are all like terms since they have a common variable (a)
(-9c, 33c,-10c) are also like terms since they have a common variable (c)
Step 2: Solve
(7a+12a+21a)+(33c-10c-9c)=40a+14c
The answer is 40a+14c

Answer: d. 75% of the screen is occupied by the image
Step-by-step explanation:
First we have to find a relation between image area and screen area.
Image area is the product of image dimensions.
Screen area is the product of screen dimensions.
We have to divide the major image dimension between the major screen dimension
Major image dim/Major screen dim = 20/5 = 4
Now we have to multiply this relation by the minor screen dimension
Minor screen dim x 4 = 4 x 4 = 16
Then we have found 5/4 = 20/16
Now we can calculate what percent of the screen area is occupied by the image area.
Major image dim x minor image dim/Major screen dim x minor screen dim
Since major image dim = major screen dim, we have:
Minor image dim/Minor screen dim = 12/16 = 0.75 = 75% of the screen
Answer: d. 75% of the screen is occupied by the image
