Find the measure of each angle indicated.
○ 44°
○ 68°
○ 59°
○ 100°
____________________Solution :-Given Information :-∠S = 95° ∠T = 85° ∠Q = 80° To Find :-The measure of ∠R Formula Used :-Sum of all angles of a Quadrilateral = 360° Calculation :-We will simply substitute the given values in the formula,
⇒ Sum of all angles of a Quadrilateral = 360°
⇒ ∠S + ∠T + ∠Q + ∠R = 360°
Substituting the values given, We get,
⇒ 95° + 85° + 80° + ∠R = 360°
Calculating further, We get,
⇒ 260° + ∠R = 360°
Transposing 260° to Right Hand Side, We get,
⇒ ∠R = 360° - 260°
Calculating further, We get,
⇒ ∠R = 100°
∴ ∠R = 100°
____________________Final Answer :-The measure of ∠R is 100°
Hence, Last option i.e., 100° is correct answer.

Students in MA238 spend on average 3.75 hours a week studying (with a population standard deviation σ = 5.17). (i) Given this fact, describe the sampling distribution of the mean if all possible random samples of size 50 were chosen. (ii) What can you say about the mean of all the possible sample means? (iii) If 250 such samples were chosen at random and for each you calculated a 95% C.I for the mean, how many such intervals would you expect to contain the true mean? (iv) If instead you calculated a 99% C.I. for the mean, how many intervals would you now expect to capture the true mean.
Answers
The sampling distribution of the mean if all possible random samples of size 50 were chosen will be 0.731.
How to depict the sample?From the information given, the mean of all the possible sample means will be:
= 5.17/✓50
= 5.17/7.071
= 0.731
It should be noted that the sample means will have the same mean as the population.
The intervals that you would expect to contain the true mean will be:
= 0.95 × 250
= 237.5 intervals

Write an expression to represent the total number of tokens that Janie and Jasmine will need to play each of the three games at least once. Let m represent the number of games that require 2 tokens; n represent the number of games that require 3 tokens; p represent the number of games that require 4 tokens. Janie plays the 3-token game four times. Write two equivalent expressions to represent the number of tokens that Janie will need to play each of the three games at least one time.
Answers
An expression to represent the total number of tokens that Janie and Jasmine will need for both to play all of the games at least once is
2(2m + 3n + 4p).
As per the question statement, "m" represents the number of games that require 2 tokens, "n" represents the number of games that require 3 tokens and "p" represents the number of games that require 4 tokens to be played once.
We are required to determine an expression that represents the total number of tokens that Janie and Jasmine will need for both, to play all of the games at least once.
As per the data provided above, a person will require [(2 * m) = 2m] tokens to play all that games that require 2 tokens, each for just one time;
He/she will require [(3 * n) = 3n] tokens to play all that games that require 3 tokens, each for just one time,
And one will require [(4 * p) = 4p] tokens to play all that games that require 4 tokens, each for just one time.
Therefore, one person who wants to play all the games available, each for once will require [2m + 3n + 4p] tokes,
But since Janie and Jasmine, each wants to play all the games atleast once, they will require 2(2m + 3n + 4p) tokens.

Step-by-step explanation:
AB and AD are tangent to circle C. Find the length of AB, if AB = 8x and AD = x + 9. Round your answer to 2 decimal places.
Answers
When a line is tangent to a circle, it forms a right angle with the radius drawn to the point of tangency. This means that triangle ABD is a right triangle with AB as the hypotenuse.
We can use the Pythagorean theorem to find the length of AB:
AB^2 = AD^2 + BD^2
Since AD = x + 9 and BD = 8x - (x + 9) = 8x - x - 9 = 7x - 9, we can substitute these values into the equation:
(8x)^2 = (x + 9)^2 + (7x - 9)^2
64x^2 = x^2 + 18x + 81 + 49x^2 - 126x + 81
64x^2 = 50x^2 - 108x + 162
14x^2 + 108x - 162 = 0
Dividing the equation by 2, we get:
7x^2 + 54x - 81 = 0
Using the quadratic formula:
x = (-b ± √(b^2 - 4ac)) / (2a)
a = 7, b = 54, c = -81
x = (-54 ± √(54^2 - 4 * 7 * -81)) / (2 * 7)
x = (-54 ± √(2916 + 2268)) / 14
x = (-54 ± √5184) / 14
x = (-54 ± 72) / 14
Now we solve for x:
Case 1: x = (-54 + 72) / 14 = 18 / 14 = 9 / 7
Case 2: x = (-54 - 72) / 14 = -126 / 14 = -9
Since the length of a segment cannot be negative, we discard the second case and focus on the positive solution.
Therefore, x = 9/7.
Substituting this value back into AB = 8x:
AB = 8 * (9/7) = 72/7 ≈ 10.29
Rounding to 2 decimal places, the length of AB is approximately 10.29 units.
Answer:
To find the length of AB, we can use the property that two tangents to a circle from the same external point are equal. This means that AB = AD. Substituting the given values, we get:
8x = x + 9
Solving for x, we get:
x = 1.5
Therefore, AB = 8x = 8(1.5) = 12.
To check our answer, we can use the Pythagorean theorem on triangle ABD, since AB is perpendicular to BD at the point of tangency. We have:
AB^2 + BD^2 = AD^2
Substituting the values, we get:
12^2 + BD^2 = (1.5 + 9)^2
Simplifying, we get:
BD^2 = 56.25
Taking the square root of both sides, we get:
BD = 7.5
Hence, the length of AB is 12 and the length of BD is 7.5.

For any value of k and h = -18, the system will have infinitely many solutions.
Hence, option (b) is the correct choice.
A coefficient matrix in linear algebra is a matrix made up of the coefficients of the variables in a group of linear equations. In order to solve systems of linear equations, the matrix is employed.
The system will have infinitely many solutions when the determinant of the coefficient matrix is equal to 0.
The determinant can be calculated from the upper triangular matrix as the product of the diagonal elements, which is 0 * (-20) * (h + 18) = 0.
Therefore, the system will have infinitely many solutions when h + 18 = 0,
