D. mz1 = 45° and mz2 = 45 are complementary angles (mz1 + mz2 = 90°), but neither angle is obtuse (greater than 90°), so the guess is wrong. This is a counter-example to show.
What are supplementary angles?A supplementary angle is an angle where the sum of two angles is 90 degrees. That is, if angle A and angle B are complementary, angle A measurement + angle B measurement = 90 degrees. Supplementary angles may be adjacent (having a common vertex and edge) or non-adjacent (having no common vertex or edge), but they always complement each other.
There are various kinds of angles to study.

At a local restaurant, the amount of time that customers have to wait for their food is normally distributed with a mean of 34 minutes and a standard deviation of 5 minutes. Using the empirical rule, determine the interval of minutes that the middle 95% of customers have to wait.
Answer:
The interval of minutes that the middle 95% of customers have to wait is between 24 and 44 minutes.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.
Approximately 95% of the measures are within 2 standard deviations of the mean.
Approximately 99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean of 34 minutes, standard deviation of 5 minutes.
Interval of minutes that the middle 95% of customers have to wait.
Within 2 standard deviations of the mean. So
34 - 2*5 = 24 minutes.
34 + 2*5 = 44 minutes.
The interval of minutes that the middle 95% of customers have to wait is between 24 and 44 minutes.
Find the sum of all the natural numbers from 1 to 400, inclusive, that are not divisible by 11. The answer is not 35840.
Answer: The sum of the numbers from 1 to 400 that are divisible by 11 is equal to $11 \cdot 666 = 7326$.
Step-by-step explanation:
To find the sum of all the natural numbers from 1 to 400 that are not divisible by 11, we can first find the sum of all the natural numbers from 1 to 400, and then subtract the sum of all the natural numbers from 1 to 400 that are divisible by 11.
The sum of the natural numbers from 1 to 400 is equal to $\frac{400 \cdot 401}{2} = 80150$.
There are 400/11 = 36 numbers that are divisible by 11 between 1 and 400, inclusive. The sum of these numbers is equal to $11 + 22 + 33 + \dots + 396 = 11(1 + 2 + 3 + \dots + 36)$. The sum of the first 36 natural numbers is equal to $\frac{36 \cdot 37}{2} = 666$. Therefore, the sum of the numbers from 1 to 400 that are divisible by 11 is equal to $11 \cdot 666 = 7326$.
Subtracting the sum of the numbers that are divisible by 11 from the sum of all the numbers from 1 to 400 gives us a final answer of $80150 - 7326 = 72824$. This is not equal to 35840, as stated in the problem.

400/11 ≈ 36Sum of the numbers divisible by 11:
1*11 + 2*11 + ... + 36*11 = 11(1 + 2 + ... + 36) = 11*36*(1 + 36)/2 = 11*18*37 = 7326Sum of the numbers not divisible by 11:
80200 - 7326 = 7287413 People fit comfortably in a 5 feet by 5 feet area. Use this value to estimate the size of a crowd that is
5 feet deep on both sides of the street along a 2.7-mile section of a parade route.
The size of the crowd that is 5 feet deep on both sides of the street along a 2.7 -mile section of a parade route is 74,131 people.
How to calculate the crowd?The number of people that can fit comfortably in a 5 feet by 5 feet area = 13.
Therefore;
The ratio of the number of people per unit area = 13/(5 × 5) = 13/25
The area A occupied by the crowd = 5 feet × 2.7 mile × 2
2.7 miles = 14,256 feet
∴ A = 5 feet × 14,256 feet × 2 = 1,42,560ft²
We then have:
[tex]\frac{number\ of\ people}{1,42,560} = \frac{13}{25}[/tex]

The ultimatum game is a popular research tool for studying topics such as fairness and altruism. The game itself is simple. Two players are told that they will be dividing up a sum of money. One player is designated as the proposer. Her job is to suggest a division of the sum. The second player is designated the responder, and he decides to either accept the proposed division (in which case the division stands and each player is paid accordingly) or to reject the proposed division, in which case both players get nothing.
Part 1 (1 point) See Hint Consider an implementation of the ultimatum game in which the players divide up a pot of $60. To keep the analysis easier, you can assume that all divisions must occur in $1 increments. What is the rational, game-theoretic solution to this game?
A. The proposer suggests a 50/50 division (so each player would get $30), and the responder rejects.
B. The proposer suggests an uneven split favorable to herself (so the proposer would get $36, and the responder would get $24), and the responder accepts.
C. The proposer suggests an uneven split favorable to the other player (so the proposer would get $24, and the responder would get $36), and the responder accepts.
D. The proposer suggests close to an all/nothing split favorable to the other player (so the proposer would get $1, and the responder would get $59), and the responder rejects.
E. The proposer suggests an uneven split favorable to the other player (so the proposer would get $24, and the responder would get $36), and the responder rejects.
F. The proposer suggests close to an all/nothing split favorable to the other player (so the proposer would get $1, and the responder would get $59), and the responder accepts.
G. The proposer suggests an uneven split favorable to herself (so the proposer would get $36, and the responder would get $24), and the responder rejects.
H. The proposer suggests a 50/50 division (so each player would get $30), and the responder accepts.
I. The proposer suggests close to an all/nothing split favorable to herself (so the proposer would get $59, and the responder would get $1), and the responder accepts.
J. The proposer suggests close to an all/nothing split favorable to herself (so the proposer would get $59, and the responder would get $1), and the responder rejects.
Part 2 (1 point) See Hint When this game is played with real people, does the result typically match the game-theory prediction discussed in Part 1? yes no
Answer:
1. The rational, game-theoretic solution to this game is:
H. The proposer suggests a 50/50 division (so each player would get $30), and the responder accepts.
2. No. When this game is played with real people, the result does not typically match the game-theory prediction discussed in Part 1.
Step-by-step explanation:
Players in a game respond with different strategies, which are usually unknown to the second player. While people are expected to act rationally, most times, they do not. They are propelled by different rationality and preferences. Therefore, players' game strategies are unpredictable.

A model of a volcano has a scale of 2.5 inches to 1.000 feet. If the model is 18 inches high, find
the height of the volcano. (1ft = 12in)
Pls help me solve this!!!
Answer:
To solve this problem, we can set up the following equation:
2.5 inches = 1,000 feet
We are told that the model is 18 inches high, so we can write the following equation:
18 inches = X feet
To solve for X, we can cross-multiply the equations to get:
(2.5 inches)X = (1,000 feet)(18 inches)
Simplifying this equation, we get:
X = 4,500 feet
Therefore, the height of the volcano is 4,500 feet.

How do you find the equation of the midline for a function?
Therefore , the solution to the given problem is the equation of the midline is: y = M+m /2 .
What is equation?An equation is a mathematical formula that connects two assertions using the equal sign (=) to denote equivalence. In algebra, an equation is a mathematical statement that establishes the equality of two mathematical expressions. For instance, an equal sign separates the components 3x + 5 and 14 in the equation 3x + 5 = 14. A mathematical formula is used to express the connection between two phrases on either side of a letter. Frequently, there is just one variable, which is also the symbol. for example, 2x - 4 = 2.
Here,
The midline equation is y = M+m /2
when a function has: o a max M AND a min m or o (if it does not have extrema) a bound above M and a bound below m, where M is the minimum bound above and m is the maximum bound below.
When one of the following conditions is true for a function, even though it has a bound below, there is no midline (even if it has a bound above)
It is solely constrained from above (or below)
Any line is midline if a function has the values (-∞, +∞)
Therefore , the solution to the given problem is the equation of the midline is: y = M+m /2 .
