Step-by-step explanation:
A local congressman must decide whether or not to vote for a bill to reduce the speed limit.
Supporters of the bill claim that the gas mileage improves at lower speeds! The congressman was given the data about the Toyota Camry gas usage - presented in the table below. (Picture Attached.)
Note: MPG stands for miles per gallon of gas.
IDENTIFY THE INDEPENDENT VARIABLE FIR THIS DATA AND WHY.
The independent variable in this data is the speed of the car. This is because the congressman is trying to determine whether or not the gas mileage improves at lower speeds.
How to explain the variablesThe dependent variable is the gas mileage, because it is the variable that is being measured and that is affected by the independent variable.
The other variables in this data are the weight of the car, the type of engine, and the year of the car. However, these variables are not being changed in this experiment, so they are not considered to be independent variables.
The data shows that the gas mileage of the Toyota Camry improves as the speed of the car decreases. This supports the claim of the supporters of the bill to reduce the speed limit.

The equation for w(width of rectangle) is: W = (P - 2L)/2
The correct answer is an option (c)
We know that the formula for the perimeter of the rectangle is:
P = 2L + 2W
where P is the perimeter of the rectangle,
L is the length of the rectangle,
and W is the width of the rectangle.
We need to rearrange this equation for w.
Consider equation,
P = 2L + 2W
P - 2L = 2L + 2W - 2L ......(subtract 2L from each side of equation)
P - 2L = 2W
(P - 2L)/2 = 2W/2 .....(divide each side by 2)
W = (P - 2L)/2
Therefore, the correct answer is W equals the quantity P minus 2 times L all over 2

a statistics activity, students are asked to determine the proportion of times that a spinning penny will with The students are instructed to spin the penny 10 times and record the number of times the penny fands up For one student, it lands tails side up six times. The student will construct a 90% confidence interval for the true proportion of tails upAre the conditions for inference met? Yes, the conditions for inference are met. No, the 10% condition is not met. No, the randomness condition is not met No, the Large Counts Condition is not met
No, the conditions for inference are not met. The Large Counts Condition is not satisfied because the number of successes (6) is less than 10.
To determine if the conditions for inference are met in this scenario, we need to consider a few key conditions: the 10% condition, the randomness condition, and the Large Counts Condition.
The 10% condition: This condition states that the sample size should be no more than 10% of the population size. In this case, the sample size is 10 (the number of times the penny was spun), and we don't have information about the population size. However, since the proportion of times the penny lands tails up is not likely to be affected by the sample size of 10, we can assume that the 10% condition is met.
The randomness condition: This condition requires that the sample is randomly selected from the population. If the student followed the instructions and spun the penny 10 times, recording the number of times it landed tails side up, and there was no bias in the way the spins were performed, we can assume that the randomness condition is met.
The Large Counts Condition: This condition is related to the number of successes and failures in the sample. It states that both the number of successes and failures should be at least 10. In this case, the student recorded 6 tails side up out of 10 spins. Since 6 is less than 10, the Large Counts Condition is not met.
Based on these conditions, we can conclude that the conditions for inference are not fully met. The 10% condition and the randomness condition are likely met, but the Large Counts Condition is not satisfied. This means that we should be cautious when making inferences about the true proportion of tails up based on this sample. It may not be appropriate to construct a confidence interval or perform statistical inference in this case due to the violation of the Large Counts Condition.

IF Tyler s currently 5 inches
tal, how many inches more
does he need to grow to be
feet tal?
Hey there! Your answer is:
7 inches
Explanation:
If Tyler is 5 inches tall, he needs to grow 7 inches to be a foot tall. This is because 12 inches are in 1 foot. We can do a simple subtraction problem to figure this out.
12 inches - 5 inches = 7 inches
Since Tyler is 5 inches tall, we know that if we subtract 12 inches from 5 inches we will get the number of inches he needs to grow.

c.If Sarah rolls a 3, what is the probability that Thomas wins?
d.If Sarah wins, what is the probability that Thomas rolled a 3
e.If Sarah wins, what is the probability that Sarah rolled a 3?
Rolls the higher number wins; if they both roll the same number, neither wins.
The answer is-
a)They both start the game with an equal chance of winning, therefore 1/2
b) If she rolls a 3, Thomas must roll a 1 or 2 for her to win, making her chance of winning 1/3.
c) Thomas has a 50% chance of winning if she rolls a three because he has to roll a 4,5 or 6 to do so.
d) In order for Sarah to win, she had to roll a 2, 3, 4, or 6. If Thomas had rolled a 1, 2, 3, 4, or 5, he would have lost. Thus, there is a 1/5 chance that he will roll a 3.
e) If Sarah wins she must have rolled a 2,3,4,5 or 6. So the probability that she rolls a three is also 1/5.

Step-by-step explanation:Naming and giving the degree of a polynomial can help people understand the different properties of an expression.
Naming Polynomials
Polynomials are named based on the number of terms in the expression.
Terms are the different coefficients and variables that are added or subtracted together.For example, the expression above has 2 terms. The first being 2x and the second being 4. There are 2 separate terms being subtracted.
There are 3 main types of polynomials
Monomials have 1 termBinomials have 2 termsTrinomials have 3 termsMost polynomials above that are just called polynomials.This specific expression is a binomial.
Degree
The degree of a polynomial is the highest exponent in the expression. For example, if the largest exponent is a 6, then the degree is also 6.
In the binomial above, there is no written exponent; however, it can be assumed that the variable "x" has an exponent of 1. Thus, this binomial is of the first degree.
Additionally, when writing a polynomial in standard form, the terms should be written in descending order of exponents.

Mr. Jones charged Roberta $32 for parts and $15 per hour for labor to repair her bicycle. He spent 3 hours repairing her bike. Which expression would be used to correctly calculate the amount Roberta owes him?
Answer:
The expression T = 15*3 + 32 could be used to correctly calculate the amount Roberta owes Mr. Jones
Step-by-step explanation:
Given that:
Amount charged for parts = $32
Per hour labor = $15
Time spent on repairing = 3 hours
Total amount = Per hour labor * Number of hours + Amount of parts
T = 15*3 + 32
Hence,
The expression T = 15*3 + 32 could be used to correctly calculate the amount Roberta owes Mr. Jones

The values of the complex expressions are ✓(x - iy) = a - ib and x² + y² = (a + ib)²(a - ib)²
Calculating the complex expressionsFrom the question, we have the following parameters that can be used in our computation:
✓(x + iy) = a + ib
Changing the signs, we have
✓(x - iy) = a - ib
Multiply both expressions
This gives
✓(x + iy) * ✓(x - iy) = (a + ib)(a - ib)
Square both sides
So, we have
(x + iy) * (x - iy) = (a + ib)²(a - ib)²
This gives
x² + y² = (a + ib)²(a - ib)²
Hence, the values of ✓(x - iy) is a - ib and x² + y² is (a + ib)²(a - ib)²

Which graph represents points on the polar curve r = –4sin(3θ)?
The graph which represents the polar curve r = -4 sin ( 3θ ) is plotted
What are Polar coordinates?Polar coordinates describe the position of a point P in the plane by its separation from the origin, r, and the angle formed between the positive x-axis and the line segment leading to P.
To graph the polar curve, we make use of the following representations:
r represents the y-axis
θ represents the x-axis
Polar coordinates can also be extended into three dimensions using the coordinates (ρ, φ, θ), where ρ is the distance from the pole, φ is the angle from the z-axis ( called the co-latitude or zenith and measured from 0 to 180° ) and θ is the angle from the x-axis ( as in the polar coordinates ).
Given data ,
Let the polar curve be represented as A
Now , the polar coordinates is given as

Step-by-step explanation:
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.

To find x, y, and z.
We utilise the following methods to find x, y, and z: r(t) = f(t) (t) * j + h (t) * k + I + g (t)

We therefore have:
I + 1/3 * j + k) = xi + yj + zk * t
it + 1/3 * jt + kt = xi + yj + zk.
In contrast:
xi = it
Divide by I x, y, and j to get 1/3 * jt.
Divide by j y = 3/9 * t zk = kt
