To answer the question, you need to determine the amount Mr. Traeger has left to spend, then find the maximum number of outfits that will cost less than that remaining amount.
Spent so far:
... 273.98 + 3×7.23 +42.36 = 338.03
Remaining available funds:
... 500.00 -338.03 = 161.97
The cycling outfits are about $80 (slightly less), and this amount is about $160 (slightly more), which is 2 × $80.
Mr. Traeger can buy two (2) cycling outfits with the remaining money.
_____
The remaining money is 161.97/78.12 = 2.0733 times the cost of a cycling outfit. We're sure he has no interest in purchasing a fraction of an outfit, so he can afford to buy 2 outfits.

Given x less than y, compare the following expressions and determine which is greater: 2x-y;2y-x. Explain your answer
Let's form the difference of the two expressions and see what we can learn.
(2y -x) -(2x -y) = 2y -x -2x +y = 3y -3x = 3(y -x)
Since y > x, this is positive, so 2y -x is greater than 2x -y.

[tex]Q_{2}[/tex] = 18
[tex]Q_{1}[/tex] = [tex]\frac{16+17}{2}[/tex] = 16.5
[tex]Q_{3}[/tex] = [tex]\frac{22+23}{2}[/tex] = 22.5
IQR = [tex]Q_{3}[/tex] - [tex]Q_{1}[/tex] = 22.5 - 16.5 = 6
Final answer:
The interquartile range (IQR) for the given data set is calculated by first arranging the data in ascending order, finding the first and third quartiles (Q1 and Q3), and subtracting Q1 from Q3. The correct IQR for this data set, following this methodology, is 6, not the mistakenly provided 7.
Explanation:
The question asks about calculating the interquartile range (IQR) of a given data set. The IQR is important because it measures the middle 50% spread of data, pinpointing where the bulk of values lie, and helps in identifying potential outliers. To compute the IQR, we first need to organize the data in ascending order, then find the first quartile (Q1) and the third quartile (Q3), and finally subtract Q1 from Q3 (IQR = Q3 - Q1).
For the provided data set: 17, 16, 21, 15, 25, 22, 18, 23, 17:
Arrange data in ascending order: 15, 16, 17, 17, 18, 21, 22, 23, 25.
Find the median (Q2), which is 18 in this case as it's the middle value.
Q1 is the median of the first half (excluding the middle value if odd number of data), so Q1 = 16.5.
Q3 is the median of the second half, hence Q3 = 22.5.
Therefore, IQR = Q3 - Q1 = 22.5 - 16.5 = 6.
Contrary to the mistaken calculation of IQR as 9 - 2 = 7 provided in the reference, the computed IQR for this data set, following the correct methodology, is 6.
How many Mondays would there be in 171 school days?
There are 5 days to a school week: Monday, Tuesday, Wednesday, Thursday and Friday.
Divide number of school days by 5 to find the number of weeks:
171 / 5 = 34.2 weeks.
The weeks start with Monday, so there would be 35 Mondays. ( 34 full weeks and the partial week would begin with a Monday)
Divide 171 by 7 (as there are 7 days in each week), obtaining 24.4. There's one Monday in every 7 days, so in 168 days there'd be exactly 24 Mondays, and in 171 days there'd still be exactly 24 Mondays, with 3 days left over.

Christa buys 14 flowerpots. Some are small and cost $2.40 each. The rest are large and cost $5.60 each. She spends a total of $49.60. Which equation models this situation? Let s represent the number of small flowerpots she buys.
A. 5.6s + 2.4(s + 14) = 49.6
B. (2.4 + 9.6)(14 – s) = 49.6
C. 2.4s + 5.6(14 – s) = 49.6
D. 5.6s + 2.8(14) = 49.6
The price of the small pots is $2.40 so you would have 2.4s ( multiply the number of small pots by the price)
She bought a total of 14 pots, so the number of large pots would be 14 - s ( subtract the number of small pots from the total )
Now you have:
L = 14-s
2.4s + 5.6(14-s) = 49.6
The answer is C.
N-6.47=4.32 what is the unknown number for N?
N = 10.79
isolate N by adding 6.47 to both sides of the equation
N = 4.32 + 6.47 = 10.79
The unknown number N in the equation N - 6.47 = 4.32 is found to be 10.79 when we add 6.47 to both sides of the equation.
To solve for the unknown number N in the equation N - 6.47 = 4.32, we must isolate the variable N on one side of the equation. We do this by adding 6.47 to both sides of the equation:
N - 6.47 + 6.47 = 4.32 + 6.47
This simplifies to:
N = 10.79
The unknown number N is therefore 10.79. When providing the final answer, we must make sure that it is reported with the correct number of significant figures, which in this case are three significant figures.

Find the measures of the angles of a triangle whose angles have a measure of x, 1/2x, and 1/6x. Also, what kind of triangle is it?
the sum of the angles in a triangle = 180°, thus
x + [tex]\frac{1}{2}[/tex] x + [tex]\frac{1}{6}[/tex] x = 180
multiply through by 6
6x + 3x + x = 1080
10x = 1080 ( divide both sides by 10 )
x = 108
the angles are 108°, 54° and 18°
Since all the angles are different and the largest is 108°
The triangle is an obtuse scalene triangle
The measures of the angles of the triangle are approximately 108 degrees, 54 degrees, and 18 degrees. This type of triangle is a scalene triangle, as all of its angles are different.
Explanation:To find the measures of the angles of a triangle whose angles are x, 1/2x, and 1/6x, we will use the fact that the sum of the angles in a triangle is always 180 degrees. The equation representing this is:
x + 1/2x + 1/6x = 180
Combine like terms:
1.6667x = 180
Then solve for x:
x ≈ 108 degrees
Now plug x into the original angle measures to get:
Angle 1 = 108 degrees
Angle 2 = 1/2x = 54 degrees
Angle 3 = 1/6x = 18 degrees
Lastly, in terms of the type of triangle, this is a scalene triangle because all of its angles are different.

Step-by-step explanation:
Answer:
OPtion C is correct answer.
Step-by-step explanation:
Given that there is a system of equations as
y =-4x+3 and y =3x+1
Table is prepared with side by side values of y for a given x
From the table we are to find the solution of the system
On analysing the table we find that the difference between two y's is
0.5, -0.2, -0.9, -1.6, -2.3,-3
Hence we select the one which shows minimum difference i.e. -0.2
For this, x = 0.6
When x =0.6, y shows two values as 0.6 and 0.8
So we approximate y value as average of these two i.e. 0.7
So solution is
(0.6, 0.7)

Mrs.Palmer bought one pair of goggles, one bathing suit, and one beach towel for each of her three daughters.Suppose she had $18 left after buying the swimming items.Write an equation to determine the amount Mrs.Palmer originally had to spend on each daughter.
To find the amount Mrs. Palmer originally had to spend on each daughter, we set up the equation as (x - 18) / 3 = y, where x is the total money she initially had and y indicates the amount spent on each daughter.
Let's denote the total amount Mrs. Palmer originally had as x.
We know she spent this on buying swimming items for her three daughters and had $18 left afterwards.
This infers that the total money she spent is (x - 18) dollars.
Since each daughter received a pair of goggles, a bathing suit, and a beach towel, this means she used this money to buy three sets of swimming items.
Therefore, the amount of money she spent on each daughter is equal to (x - 18)/3.
The equation to find out what x (the amount Mrs. Palmer originally had) is therefore:
(x - 18) / 3 = y
where y represents the amount she spends on each daughter.

Find x- and y-intercepts. Write ordered pairs representing the points where the line crosses the axes. y= 1/3 x− 2/3
Given the graph of a line y=−x.Write an equation of a line which is perpendicular and goes through the point (8,2).
Answer:
1. (0, -2/3), (2, 0)
2. y = x-6
Step-by-step explanation:
1. Since the equation is in slope-intercept form, you know the y-intercept is -2/3. The x-coordinate there is 0, so the ordered pair is (0, -2/3).
Substituting y=0 into the equation gives the value of the x-intercept.
... 0 = 1/3x -2/3
... 0 = x - 2 . . . . . multiply by 3
... 2 = x . . . . . . . . add 2
The x-intercept is (2, 0).
2. The given line has slope -1, so the perpendicular line has a slope that is the negative reciprocal of that: -1/-1 = 1. Then the point-slope equation of the line can be written ...
... y = 1(x -8) +2
... y = x - 6 . . . . simplify
(1)
to find the intercepts
• let x = 0, in the equation for y-intercept
• let y = 0, in the equation for x-intercept
x = 0 : y = - [tex]\frac{2}{3}[/tex] → (0, - [tex]\frac{2}{3}[/tex]) ← y-intercept
y = 0 : [tex]\frac{1}{3}[/tex] x - [tex]\frac{2}{3}[/tex] = 0 ( multiply by 3 )
x - 2 = 0 → x = 2 → (2, 0 ) ← x- intercept
(2)
the equation of a line in slope-intercept form is
y = mx + c ( m is the slope and c the y-intercept )
y = - x is in this form with slope m = - 1
the slope of a perpendicular line = - [tex]\frac{1}{m}[/tex] = 1
the partial equation of the perpendicular line is
y = x + c
to find c substitute (8, 2 ) into the partial equation
2 = 8 + c → c = 2 - 8 = - 6
y = x - 6 ← equation of perpendicular line

an angle measures 2 degrees more than 3 times it’s complement. find the measure of its complement.
If the angle is 90 degrees, then the complement would be 27, because 90 / 3 = 30, and 30 - 3 = 27. Basically, you divide the angle by 3 and subtract 3 to find the complement if this is the case.
Answer:
22⁰
Step-by-step explanation:
Angle = x
Complement = 90 - x
Given:
x = 3 (90 - x) + 2
x = 270 - 3x + 2
4x = 272
x = 68
Complement = 90 - 68 = 22⁰

Find the derivative of each of the following (inverse function)
[tex]f(x) = x^2 arctan(x)[/tex]
[tex]f(x) = xarcsin(1-x^2)[/tex]
ANSWER 1
Note that,
[tex]f(u)=tan^{-1}(u)[/tex]
is the same as
[tex]f(u)=arctan(u)[/tex]
We apply the product rule.
[tex]f(x)=x^2tan^{-1}(x)[/tex]
So we keep the second function and differentiate the first,plus we keep the first function and differentiate the second.
[tex]f'(x)=(x^2)'tan^{-1}(x)+x^2(tan^{-1}(x))' [/tex]
Recall that,
If
[tex]f(u)=tan^{-1}(u)[/tex]
Then,
[tex]f'(u)=\frac{1}{1+u^2}} \times u'[/tex]
This implies that,
[tex]f'(x)=2xtan^{-1}(x)+\frac{x^2}{x^2+1} [/tex]
ANSWER 2
We apply the product rule and the chain rules of differentiation here.
[tex]f(x)=xsin^{-1}(1-x^2)[/tex]
[tex]f'(x)=x'sin^{-1}(1-x^2)+x(sin^{-1}(1-x^2))' [/tex]
Recall that,
If
[tex]f(u)=sin^{-1}(u)[/tex]
Then,
[tex]f'(u)=\frac{1}{\sqrt{1-u^2}} \times u'[/tex]
This implies that,
[tex]f'(x)=sin^{-1}(1-x^2)+x \times \frac{1}{\sqrt{1-(1-x^2)^2}}\times (-2x) [/tex]
[tex]f'(x)=sin^{-1}(1-x^2)-\frac{2x^2}{\sqrt{1-(1-2x^2+x^4)}} [/tex]
[tex]f'(x)=sin^{-1}(1-x^2)-\frac{2x^2}{\sqrt{1-1+2x^2-x^4}}[/tex]
[tex]f'(x)=sin^{-1}(1-x^2)-\frac{2x^2}{\sqrt{2x^2-x^4}}[/tex]
The Fall Festival charges $0.75 per ticket for the rides. Kendall bought 18 tickets for rides and spent a total of $33.50 at the festival. She only spent her money on ride tickets and admission into the festival. The price of admission is the same for everyone. Use y to represent the total cost and x to represent the number of ride tickets.
(a) Define your variables.
(b) Write a linear equation to calculate the cost for anyone who only pays for festival admission and rides
(c) Explain your answer to Part B.
Part (a)
The variable y is the dependent variable and the variable x is the independent variable.
Part (b)
The cost of one ticket is $0.75. Therefore, the cost of 18 tickets will be:
[tex]0.75\times 18=13.5[/tex] dollars
Now, we know that Kendall spent her money only on ride tickets and fair admission and that she spent a total of $33.50.
Therefore, the price of the fair admission is: $33.50-$13.50=$20
If we use y to represent the total cost and x to represent the number of ride tickets, the linear equation that can be used to determine the cost for anyone who only pays for ride tickets and fair admission can be written as:
[tex]y=0.75x+20[/tex]......Equation 1
Part (c)
The above equation is logical because, in general, the total cost of the rides will depend upon the number of ride tickets bought and that will be 0.75x. Now, even if one does not take any rides, that is when x=0, they still will have to pay for the fair admission, and thus their total cost, y=$20.
Likewise, any "additional" cost will depend upon the number of ride tickets bought as already suggested. Thus, the total cost will be the sum of the total ride ticket cost and the fixed fair admission cost. Thus, the above Equation 1 is the correct representative linear equation of the question given.
