∠JEK + ∠DFH = 90°
Find:
relationship, if any, of ∠JEK to angles CFL, HFG, LFE
Solution:
We note that ∠DFG = 90° = ∠DFH + ∠HFG, so ∠JEK ≅∠HFG.
We also note that ∠HFG and ∠CFL are vertical angles, so ∠JEK ≅∠CFL.
And ∠LFE and ∠DFH are vertical angles, so ∠JEK + ∠LFE = 90°.
Evaluating the choices, we find
A) false. The angles are not complementary, they are equal.
B) false. The angles are not equal, they are complementary.
C) false. The angles are not supplementary, they are equal.

A man has 28 coins in his pocket, all of which are dimes and quarters. if the total value of his change is 520 cents, how many dimes and how many quarters does he have?
Answers
To solve the problem, we can set up a system of equations. The solution is 12 dimes and 16 quarters.
Explanation:To solve this problem, we can set up a system of equations. Let's say the number of dimes is x and the number of quarters is y. We know that the total number of coins is 28, so we can write the equation:
x + y = 28
We also know that the value of the dimes is 10 cents and the value of the quarters is 25 cents. The total value of the change is 520 cents, so we can write the equation:
10x + 25y = 520
We can solve this system of equations using substitution or elimination. Let's use substitution:
From the first equation, we can express x in terms of y:
x = 28 - y
Substitute this value of x into the second equation:
10(28 - y) + 25y = 520
Simplify and solve for y:
280 - 10y + 25y = 520
15y = 240
y = 16
Now substitute this value of y back into the first equation to find x:
x + 16 = 28
x = 12
Therefore, the man has 12 dimes and 16 quarters.

Find the volume of a sphere with a great circle area of 201.06 square inches
Answers
so, we know if we cut the sphere like a cantaloupe, in half, the circular inner-part of the cantaloupe will have an area of 201.6 in².
keeping in mind that, the radius of that circular section, is the same radius of the sphere, what is it anyway?
[tex]\bf \textit{area of a circle}\\\\ A=\pi r^2~~ \begin{cases} r=radius\\ -----\\ A=201.06 \end{cases}\implies 201.06=\pi r^2 \\\\\\ \cfrac{201.06}{\pi }=r^2\implies \sqrt{\cfrac{201.06}{\pi }}=r\\\\ -------------------------------[/tex]
[tex]\bf \textit{volume of a sphere}\\\\ V=\cfrac{4\pi r^3}{3}\qquad \qquad \implies V=\cfrac{4\pi \left( \sqrt{\frac{201.06}{\pi }} \right)^3}{3}\implies V=\cfrac{4\pi \left( \frac{\sqrt{201.06^3}}{\sqrt{\pi ^3}} \right)}{3} \\\\\\ V=\cfrac{4\pi \cdot \frac{\sqrt{201.06^3}}{\pi \sqrt{\pi }}}{3}\implies V=\cfrac{\frac{4\sqrt{201.06^3}}{\sqrt{\pi }}}{3}\implies V=\cfrac{4\sqrt{201.06^3}}{3\sqrt{\pi }}[/tex]
Final answer:
To find the volume of a sphere with a given great circle area, solve the equation 4πr² = 201.06 to find the radius, then use the formula V = (4/3)πr³ to calculate the volume. The volume is approximately 267.97 cubic inches.
Explanation:
To find the volume of a sphere with a given great circle area, we first need to find the radius of the sphere. The great circle area is equal to the surface area of the sphere, which is 4πr², where r is the radius of the sphere. In this case, the great circle area is 201.06 square inches, so we can solve the equation 4πr² = 201.06 to find the radius. Once we have the radius, we can use the formula for the volume of a sphere, V = (4/3)πr³, to calculate the volume.
First, let's solve the equation 4πr² = 201.06 for r:
4πr² = 201.06
r² = 201.06 / (4π)
r² ≈ 16.06
r ≈ √16.06 ≈ 4.01
Now that we have the radius, we can calculate the volume using the formula V = (4/3)πr³:
V ≈ (4/3)π(4.01)³ ≈ 267.97 cubic inches

2) Amount of time spent at school each day and number of text sent per day
3) The number of licks taken and the size of the Tootsie Pop
Answers
#2 - No relationship.
#3 - Negative
A positive relation between two things means that they are proportional to each other. One affects the other thing.
1) Smoking and cases of lung cancer. This is positive. As smoking affects lungs and can cause lung cancer. So, with increased smoking comes the increased risk of lung cancer thus increasing cases of lung cancer.
2) Amount of time spent at school each day and number of text sent per day - These two events are independent of each other. They are not based on each other. Hence, no relationship here.
A negative relation implies that if one thing increases, the other decreases.
3) The number of licks taken and the size of the Tootsie Pop. This is negative. As the number of licks increases, the size of the pop decreases.

Answers
Answer:
Scatterplot
Step-by-step explanation:
Bivariate data means that the data is in two variables. For example, if the height of the students is plotted against their age, this data will be the bivariate data.
A bivariate data is represented using the graph known as Scatter Plot. One variable is plotted along x-axis and second variable is plotted against y-axis. After plotting the two variables we can observe the relation(association) between the two variable using the line of best-fit which models the relation between the two variables.
So, the answer to this question is Scatterplot.
A graph that displays bivariate data is called a Scatterplot. It represents two variables and can indicate Positive Association, Negative Association, or No Association, based on the scatter pattern.
Explanation:In the field of Statistics, a graph that displays bivariate data is referred to as a Scatterplot. Bivariate data represents two different variables, and a scatterplot is a graphical representation that uses dots to show the relationship, if any, between these two sets of data.
When looking at a scatterplot, the patterns of the dots can indicate associations. Positive Association is when as one variable increases, so does the other. Negative Association is when one variable decreases as the other increases. If the dots seem randomly scattered, it exhibits No Association.

Cancelling a dance class after several students hurt themselves is an example of which risk management strategy?
Answers
Avoid strategy as the threat/risk is directly related to identified threats and these sources of threats are cancelled
Explanation:
Risk management is defined as:
The identification , analysis, control and possibly elimination of any undesired hazards or risks arising from a certain situation or activity
There are four risk management strategies which are:
1- Avoid: To eliminate the risk by totally avoiding the situation/activity
2- Mitigate: To try to reduce the expected hazards of the situation/activity
3- Accept: To accept the hazards and take your chances
4- Transfer: To outsource the risk (as in case of insurance)
In case of cancelling the dance class, we can note that the risks are directly related to identified threats and the threats are totally cancelled in order to avoid those risks. Therefore, the best strategy describing this situation is "avoid strategy"
Hope this helps :)
The scenario of cancelling a dance class due to student injuries is an example of the 'risk avoidance' strategy in risk management, which aims to avoid potential harm.
Explanation:Canceling a dance class due to multiple students getting injured is a risk management strategy known as risk avoidance. This strategy eliminates the risk by not participating in the activity that could lead to the risk. In this context, the dance class risks injury to the students. In such a scenario, the dance instructor or school chooses to avoid the risk (moral hazard) by cancelling the activity (i.e., the dance class), thereby protecting the students from further harm. This is a common approach employed in situations where the potential adverse outcomes of risk outweigh any potential benefits of the activity.

You plan on financing a new road bike for $2,500. The bike shop offers a 13.5% APR for a 24 month loan. Use this information, and the table above, to determine the monthly payments. Round your answer to the nearest cent.
Answers
Given that the financing is for a new road bike of $2,500 and that the bike shop offers a 13.5% APR for a 24 month loan.
Thus, PV = $2,500; r = 13.5% = 0.135; t = 12 payments (since payment is made monthly); n = 2 years (i.e. 24 months)
Thus,
[tex]2500=P\left( \frac{1-\left(1+ \frac{0.135}{12} \right)^{-2\times12}}{ \frac{0.135}{12} } \right) \\ \\ =P\left( \frac{1-\left(1+ 0.01125 \right)^{-24}}{ 0.01125 } \right)=P\left( \frac{1-\left(1.01125 \right)^{-24}}{ 0.01125 } \right) \\ \\ =P\left( \frac{1-0.764531}{ 0.01125 } \right)=P\left( \frac{0.235469}{ 0.01125 } \right)=20.9306P \\ \\ \Rightarrow P= \frac{2500}{20.9306} =119.44[/tex]

Answers
WZ + 41 = ZWX
From here, we must clear We must replace the value of WZ.
The value of WZ is given by
WZ=180
We have then:
ZWX = 180 + 41
ZWX = 221 degrees
Answer:
the measure of convex arc upper ZWX is:
ZWX = 221 degrees
The measure of convex arc upper ZWX is 180 degrees.
Explanation:The measure of convex arc upper ZWX can be found by considering the angles formed by the diameters WZ and XR. Since WZ and XR are diameters of the circle, they intersect at the center of the circle. The angle formed by the diameters at the center is a right angle, which means that arc upper ZWX is a semicircle. A semicircle has a measure of 180 degrees. Therefore, the measure of convex arc upper ZWX is 180 degrees.
