The sum of opposite angles of a cyclic quadrilateral is 180°
It must satisfy the following:
A+C=180° and B+D=180°
Only choice A and B and D satisfy.
The correct options are options A, B, and D.
What is a cyclic quadrilateral?A quadrilateral having all its corners on a circle plus opposite angles' sum is 180° called a cyclic quadrilateral.
A) ∠A =90°
∠B=90°
∠C =90°
∠D =90°
∠A + ∠C = 180°
∠B + ∠D =180°
So, this quadrilateral can come from a cyclic quadrilateral.
B) ∠A =80°
∠B=80°
∠C =100°
∠D =10 0°
∠A + ∠C = 180°
∠B + ∠D =180°
So, this quadrilateral can come from a cyclic quadrilateral.
Similarly, options C, D, and E also can be checked whether they can come from a cyclic quadrilateral or not.
C) Cannot come from a cyclic quadrilateral since ∠A + ∠C =140°≠180°.
D) ∠A + ∠C = 180°
∠B + ∠D =180°
So, this quadrilateral can come from a cyclic quadrilateral.
E)Cannot come from a cyclic quadrilateral since∠A + ∠C = 170°≠180°.
Therefore, The correct options are options A, B, and D.

However, your team would like to expand its orders beyond the state of Indiana. By the end of this year, you think you would like your total proportion of orders from Indiana to be between 0.66 and 0.73. If you took a simple random sample of 99 current orders, what is the probability that the sample proportion of sales to Indiana residents is between 0.66 and 0.73
This question is incomplete, the complete question is;
Based on historical data, your team knows what proportion of the company's number of orders come from Indiana residents. However, your team would like to expand its orders beyond the state of Indiana. By the end of this year, you think you would like your total proportion of orders from Indiana to be between 0.66 and 0.73. If you took a simple random sample of 99 current orders, what is the probability that the sample proportion of sales to Indiana residents is between 0.66 and 0.73
Note: You should carefully round any intermediate calculations to 4 decimal places to match wamap's approach and calculations. After you round to 4 places, use THAT rounded value in later steps. You may need an appropriate population proportion (which you actually found in a previous problem).
Some data:
Total population: 2327
Indiana residents: 1845
Other: 482
Frequency table results for Total Sales:
Count = 2327
Total Sales Frequency
0 to 200 1960
200 to 400 303
400 to 600 53
600 to 800 9
800 to 1000 2
Answer:
The probability that the sample proportion of sales to Indiana residents is between 0.66 and 0.73 is 0.0612
Step-by-step explanation:
Given the data in the question;
p" = Indiana residents / Total population
p" = 1845 / 2327
p" = 0.7929
Now, the probability that the sample proportion of sales to Indiana residents is between 0.66 and 0.73 will be;
P( 0.66 < p < 0.73 ) = P{ [x1 - p" / √( p"(1-p")/n )] < p < [x2 - p" / √( p"(1-p")/n )] }
we substitute
= P{ [0.66 - 0.7929 / √( 0.7929(1-0.7929)/99 )] < p < [0.73 - 0.7929 / √( 0.7929(1-0.7929)/99 )] }
= P{ [-0.1329 / 0.0407] < p < [-0.0629 / 0.0407] }
= P{ -3.2654 < z < -1.5455 }
= ⊕( -1.5455) - ⊕(-3.2654)
from the standard normal table;
= 0.0618 - 0.0006
P( 0.66 < p < 0.73 ) = 0.0612
Therefore, the probability that the sample proportion of sales to Indiana residents is between 0.66 and 0.73 is 0.0612

Find the value of x and y
Answer:
x = 63°, y = 27°
Step-by-step explanation:
We know that x + y = 90°
Since ∠ x and 117° are on the same line, they are adjacent angles and add up to 180°.
x + 117 = 180
x = 180 - 117
x = 63°
Now back to the first equation:
x + y = 90°
63 + y = 90
y = 90 - 63
y = 27°
Answer:
x=63
y=27
Step-by-step explanation:
x y 117 son suplementarios x+117=180, entonces para obtener x debemos de restarle 117 a 180
el angul x y y son complementarios x+y=90 , en el anterior x nos dio igual a 63, entonces 90-63=y(que y es 27)

2. (a) If ^nP2= 20, find the value of n.
2
Answer:
[tex]n = 5[/tex]
Step-by-step explanation:
Given
[tex]^nP_2 = 20[/tex]
Required
Find n
To do this, we apply permutation formula.
[tex]^nP_r = \frac{n!}{(n-r)!}[/tex]
So, we have:
[tex]\frac{n!}{(n-2)!} = 20[/tex]
Expand the numerator
[tex]\frac{n(n-1)(n-2)!}{(n-2)!} = 20[/tex]
Divide by (n-2)!
[tex]n(n-1)= 20[/tex]
Expand
[tex]n^2 - n = 20[/tex]
[tex]n^2 - n - 20 = 0[/tex]
Expand
[tex]n^2 +4n -5n - 20 = 0[/tex]
Factorize
[tex]n(n+4)-5(n+4)= 0[/tex]
[tex](n-5)(n+4) = 0[/tex]
[tex]n - 5 = 0[/tex] or [tex]n + 4 = 0[/tex]
[tex]n = 5[/tex] or [tex]n = -4[/tex]
Since n cannot be negative, then:
[tex]n = 5[/tex]

water is placed in a cylinder bucket own a bench The bucket has a diameter of 12 in and a height of 12 in The bench is capable of holding 200 lb per cubic feet water weighs 64.2 cubic feet how much does the water in the bucket weigh
Answer:
bucket of water = 50.397 lbs
Step-by-step explanation:
Pi(r^2)(h) = volume
3.14(6^2)(12) = 1356.48 in^3 = volume of bucket
one ft^3 = 12 x 12 x 12 = 1728 in^3
1356.48/1728 = 0.785 ft^3 (volume of bucket)
0.785(64.2) = 50.397 lbs

Answer:
- Discount car rentals charges less daily
- After 3 days
Step-by-step explanation:
Required
Which charges less per day
When is the total cost the same
First, calculate the slope (m)
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
From the table, we have:
[tex](x_1,y_1) = (2,185)[/tex]
[tex](x_2,y_2) = (6,345)[/tex]
So, we have:
[tex]m = \frac{345 - 185}{6 - 2}[/tex]
[tex]m = \frac{160}{4}[/tex]
[tex]m = 40[/tex]
The equation is then calculated as:
[tex]y = m(x - x_1) + y_1[/tex]
[tex]y = 40(x - 2) + 185[/tex]
[tex]y = 40x - 80 + 185[/tex]
[tex]y = 40x + 105[/tex]
So, the equation of the table (i.e. Discount Car rental) is: [tex]y = 40x + 105[/tex]
While the equation of Pay Less is: [tex]y = 55x + 60[/tex]
The company that charges less per day has the smaller slope and that is: Discount car rental because the slope (40) is less than the slope (55)
For the total cost to be the same, we simply equate both expressions:
i.e.
[tex]y = y[/tex]
[tex]55x + 60 = 40x + 105[/tex]
[tex]55x - 40x = - 60 + 105[/tex]
[tex]15x =45[/tex]
[tex]x = 3[/tex]

What is the equation of the line
Answer:
y=-7
Step-by-step explanation:
An integrated circuit factory has three machines X, Y, and Z. Test one integrated circuit produced by each machine. Either a circuit is acceptable (a) or it fails (f). An observation is a sequence of three test results corresponding to the circuits for machines X, Y, and Z, respectively. For example, aaf is the observation that the circuits from X and Y pass the test and the circuit from Z fails the test.
a. What are the elements of the sample space of this experiment?
b. What are the elements of the sets:
ZF={circuit from Z fails},
XA ={circuit from X is acceptable}.
c. Are ZF and XA mutually exclusive?
d. Are ZF and XA collectively exhaustive?
e. What are the elements of the sets C={more than one circuit acceptable}, D={at least two circuits fail}.
f. Are C and D mutually exclusive?
g. Are C and D collectively exhaustive?
Answer:
Kindly check explanation
Step-by-step explanation:
Acceptable = a
Fails = f
For machines X, Y, Z ;
Sample space, S = {aaa, aaf, aff, fff, faa, afa, ffa, faf}
Total elements in sample space = 8
B.)
Elements of the set:
ZF={circuit from Z fails},
XA ={circuit from X is acceptable}.
ZF = {aaf, aff, fff, faf}
XA = {aaa, aaf, aff, afa}
C.)
c. Are ZF and XA mutually exclusive?
Check if ZF n XA = ∅
ZF n XA = {aaf, aff}
Hence, ZF and XA are not mutually exclusive
d. Are ZF and XA collectively exhaustive?
To be collectively exhaustive :
ZF u XA = Sample space
ZF u XA = {aaa, aaf, aff, afa, faf, fff}
{aaa, aaf, aff, afa, faf, fff} ≠ sample space
Hence, ZF and ZA are not collectively exhaustive.
e. What are the elements of the sets
C={more than one circuit acceptable},
C = {aaa, aaf, faa, afa}
D={at least two circuits fail}.
D = {ffa, faf, aff, fff}
f. Are C and D mutually exclusive?
Check if C n D = ∅
C n D = ∅
Hence, A and D are mutually exclusive
g. Are C and D collectively exhaustive?
To be collectively exhaustive :
C u D = Sample space
C u D = {aaa, aaf, aff, afa, faf, fff}
{aaa, aaf, faa, ffa, aff, afa, faf, fff} = sample space
Hence, C and D are collectively exhaustive.

Reggie Jackson, one of the great baseball batters of modern times, was called Mr. October by his fans because he seemed to excel in the World Series. During the regular season, Reggie had 2584 hits in 9864 official at bats for a batting average (proportion of hits) of 0.262. During League Championship Series, he had 37 hits in 163 official at bats for a 0.227 batting average. During World Series play, he had 35 hits in 98 official at bats for a batting average of 0.357. Do you think the nickname is justified, based on the data
Answer:
Since 2.1387 is Greater Than 1.645;
we reject null hypothesis; we conclude that, the nickname is justified based on the data.
Step-by-step explanation:
Given the data in the question;
Null hypothesis H₀ : p = 0.262
Alternative Hypothesis H₁ : p > 0.262.
p" = 0.357
q = 1 - p = 1 - 0.262 = 0.738
n = 98
so;
z = (p" - p) / √(pq/n)
we substitute
z = (0.357 - 0.262) / √((0.262×0.738) / 98)
z = 0.095 / 0.04441869
z = 2.1387
at 5% CONFIDENCE INTERVAL
z-critical = 1.645
Since 2.1387 is Greater Than 1.645;
we reject null hypothesis; we conclude that, the nickname is justified based on the data.
