Remark
The longer the line, the larger the arc is. So
How to put in order.
It can be shown that the angle opposite the chord is related to the arc length by α = arc length / r Since r never changes, you are left with
α = k * chord length.
So what you conclude is that the larger the angle, the larger the arc length.
The largest angle is Q so the length of the arc opposite Q is the largest. The other two lines are handled the same way.
Answer:
Arc length PR is the largest.Arc Length PQ is the second largest.Arc Length RQ is the Smallest.Guys, Can you please help me with these questions

At Goodies restaurant the quantity of large pizza sold is 200 at the unit price of $15. suppose the price elasticity of demand for pizza is $1.5, and you would to increase the quantity sold to 250,then the new price must be?
The new price of pizza when the quantity sold is increased to 250 is $12.45.
What is the new price of pizza?Price elasticity of demand measures the responsiveness of quantity demanded to changes in price of the good.
Price elasticity of demand = percentage change in quantity demanded / percentage change in price
Percentage change in quantity demanded = (250 / 200) - 1 = 25%
Percentage change in price = 25% / 1.5 = 16.67%
New price = (0.1667 x 15) - 15 = $12.45

Every day, Jorge buys a lottery ticket. Each ticket has a probability of 0.2 of winning a prize. After seven days, what is the probability that Jorge has won at least one prize? Round your answer to four decimal places.
(a) The probability that Jorge has won at least one prize is ____.
Step-by-step explanation:
the probability to win is 0.2.
the probability to lose is 1-02 = 0.8.
there is no sure win after at least n trials.
on day 1 the probability to win is 0.2.
on day 2 the probability to win at least once is
the probability to have won on day 1 but not on day 2, plus the probability to have won on day 2 but not on day 1 plus the probability to have won on both days :
0.2×0.8 + 0.8×0.2 + 0.2×0.2 = 0.32 + 0.04 = 0.36
...
on day 7 we have
the probability to have won on one day but not on 6 days times the combination of picking 1 day out of 7,
plus the probability to have won on 2 days but not on 5 days times the combinations to pick 2 out of 7,
plus the probability to have won on 3 days but not on 4 days times the combinations to pick 3 out of 7,
...
plus the probability to have won on all 7 days.
that is
0.2.×0.8⁶ × 7 +
+ 0.2²×0.8⁵ × C(7, 2) +
+ 0.2³×0.8⁴ × C(7, 3) +
+ 0.2⁴×0.8³ × C(7, 4) +
+ 0.2⁵×0.8² × C(7, 5) +
+ 0.2⁶×0.8 × 7 +
+ 0.2⁷
but before we lose ourselves in tons of little operations, this is the same as the opposite of having lost on all 7 days.
that is
1 - 0.8⁷ = 1 - 0.2097152 = 0.7902848 ≈ 0.7903
so, the probability that Jorge has won at least one prize is
0.7903

Triangle XYZ is equilateral with vertices located on circle W.
Circle W is shown. Line segments W Y, W Z, and W X are radii. Lines are drawn to connect the points on the circle to form a triangle. Sides Z X, X Y, and Z Y are congruent.
Which measurements are correct? Select two options.
mArc X Y = 60°
mArc Y Z = 120°
mArc Z X = 180°
m∠XWZ = 60°
m∠YWZ = 120°
Based on the inscribed angle theorem, the measurements that are correct are: B. m(arc YZ) = 120°; E. m∠YWZ = 120°.
What is the Inscribed Angle Theorem?The inscribed angle theorem states that the measure of an inscribed angle in a circle equals the twice the measure of the intercepted arc or twice the measure of the central angle.
In the circle given, since the triangle is an equilateral triangle, therefore, all its angles each equals 60°. Therefore:
m(XY) = m(YZ) = m(ZX) = 2(60°) = 120°.
The central angles, m∠XWZ = m∠XWY = m∠YWZ = 120°.
Therefore, the correct measurements are: B. m(arc YZ) = 120°; E. m∠YWZ = 120°.

Five runners need to be arranged in 5 lanes for a race so that there is a runner in each lane. How many unique ways are there to arrange the runners in the 5 lanes?
Answer:
25
Step-by-step explanation:
When answer questions about unique combinations, there are usually two ways people go about finding the solutions.
First, sometimes it can take a while, but it often helps people visualize the question if they jot down or sketch each different combination. Then, they can just count them up at the end to find there answer.
The easeier way is to use a quick math trick. If you have 5 runners, with 5 potential lanes each runner could start in, you can just multiply these two variables together to get your answer of the number of possible options.
So,
5 runners * 5 lanes = 25 possible combinations for each lane and runner
The number of unique ways that the runner can be arranged in 5 lanes for a race is 120.
What are Combinations?Combinations are defined as the arrangement of objects or numbers in a way such that the order of the arrangement does not matter.
Total number of runners = 5
Total number of lanes = 5
Number of ways that 5 runners can be arranged = 5! = 120
Hence the number of ways is 120.

so now you know traingles BAC, and CAD have three sides which all measure the same making ABC equal to ADC
Graph a line representing the proportional relationship with slope 3 containing the point (2, 6).
To graph the line, plot two points on the line.
Answer:
(1, 3) and (0, 0)
Step-by-step explanation:
y = mx + b
m is the slope which is 3 (given)
b is the y intercept
(x, y) → (2, 6)
6 = 3(2) + b
6 = 6 + b
b = 0
so the equation is y = 3x
one point:
y = 3(1)
y = 3 when x = 1
(1, 3)
y = 3(0)
y = 0 when x = 0
(0, 0)

1/2(3π)(6)9π units²The area of each cross section of the cone and pyramid is the same which is 2[tex]\pi[/tex].
This is because the cone and pyramid are similar solids, and the cross sections are taken at equal heights.
The similarity of the cone and pyramid can be seen by comparing the triangles formed by the apex, a point on the base, and the intersection of the plane with the solid. These triangles are similar because they have the same angles.
The fact that the cross sections are taken at equal heights means that the triangles are similar in size as well. This means that the areas of the triangles are also the same.
Therefore, the area of each cross section of the cone and pyramid is the same.
[tex]\pi[/tex][tex]h^2[/tex] / (1/2) h*h = 2[tex]\pi[/tex][tex]h^2[/tex] / [tex]h^2[/tex] = 2[tex]\pi[/tex]
The cross sections of the cone and pyramid are both triangles. The triangles are similar because they have the same angles.
