Aidan walked from home to his friend house, which is 900 m away in 15 minutes He stayed for 30 minutes ,then walked home in 10 minutes. What is distance(d)
The distance (d) that Aidan traveled is 1500 meters.
To find the distance Aidan walked, we need to consider the total distance he covered during the entire journey.
First, Aidan walked from home to his friend's house, covering a distance of 900 meters in 15 minutes. We can calculate his speed using the formula: Speed = Distance / Time. Therefore, Aidan's speed during this leg of the journey is 900 meters / 15 minutes = 60 meters per minute.
After reaching his friend's house, Aidan stayed for 30 minutes. This period of time does not contribute to the distance he walks, as he remains stationary.
Finally, Aidan walks back home in 10 minutes. Using the speed calculated earlier (60 meters per minute), we can determine the distance covered: Distance = Speed * Time = 60 meters/minute * 10 minutes = 600 meters.
Therefore, the total distance Aidan walked is 900 meters + 600 meters = 1500 meters.
Hence, the distance (d) that Aidan traveled is 1500 meters.

How do numbers help us predict the ebbs and flows in our lives? Think about things like circadian rhythms.
Numbers play a crucial role in helping us predict the ebbs and flows in our lives. They are used to measure and quantify patterns and cycles that occur in our daily lives, such as circadian rhythms.
Circadian rhythms are the physical, mental, and behavioral changes that follow a 24-hour cycle, responding primarily to light and darkness in an organism's environment. Numbers help us measure and track these rhythms, allowing us to predict when we will feel awake or sleepy, hungry or full, and so on.
For example, we know that the average human circadian rhythm is 24.2 hours, and that our bodies produce the hormone melatonin at night to help us sleep. By measuring and tracking these numbers, we can predict when we will feel tired and need to sleep, and when we will feel awake and alert.
Numbers also help us predict other patterns in our lives, such as our menstrual cycles, the best times to exercise, and when we are most likely to get sick. By tracking and measuring these numbers, we can better understand and predict the ebbs and flows in our lives and make more informed decisions about our health and well-being.

A large, regular hexagon is drawn on the ground, and a man stands at one of the vertices. The man flips a coin. If the coin lands heads, he walks counterclockwise along the edge of the hexagon until reaching the next nearest vertex. If the coin lands tails, he walks clockwise around the hexagon until reaching another vertex. Once there, he repeats the process. The man flips the coin a total of six times. What is the probability that the man is standing where he started when he is finished
The probability that the man is standing where he started when he is finished is 1/2
What is probability?Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty.Given is that a large, regular hexagon is drawn on the ground, and a man stands at one of the vertices. The man flips a coin. If the coin lands heads, he walks counterclockwise along the edge of the hexagon until reaching the next nearest vertex. If the coin lands tails, he walks clockwise around the hexagon until reaching another vertex. The man flips the coin a total of six times.
Now, for either all heads or all tails, the person will land at same place. So, we can write that -
number of favorable outcomes = N{F} = 6
total number of favorable outcomes = N{T} = 12
P{E} = N{F}/N{6}
P{E} = 6/12
P{E] = 1/2
Therefore, the probability that the man is standing where he started when he is finished is 1/2.

Without working out the multiplication, which product is larger, why? 3 × 1/5 or 3 × 1/10
Answer:
The product that will be larger is 3x1/5
Step-by-step explanation:
So in order to know this we have to look at the fractions. We already know that 1/5 is larger than 1/10. To double check our work, we can convert these fractions into percents. 1/5 being 20% and 1/10 being 10%. So now that we have prooved 1/5 is larger, multiplying the larger fraction by three will give us a larger product.

show that the vector of residuals, r is orthogonal to every column of x
The vector r is orthogonal to every column of X.
Let y be the response vector, X be the design matrix, and \($\hat{y}$\) be the vector of fitted values,
where \(\hat{y} = X\hat{\beta}$ and $\hat{\beta}$\) is the vector of estimated coefficients.
The vector of residuals is defined as \(r = y - \hat{y}$.\)
To show that r is orthogonal to every column of X, we need to show that \($r^T X_j = 0$\) for all j,
where \($X_j$\) is the j-th column of X.
\($r^T X_j = (y - \hat{y})^T X_j$\)
\($= y^T X_j - \hat{y}^T X_j$\)
\($= y^T X_j - (\hat{\beta}^T X^T)_j X_j$\)\((using the fact that $\hat{y} = X\hat{\beta}$)\)
\(= y^T X_j - X_j^T (\hat{\beta}^T X^T)$ (using the fact that $(AB)^T = B^T A^T$)\)
\($= y^T X_j - X_j^T X \hat{\beta}$\)
\(= y^T X_j - X_j^T X (X^T X)^{-1} X^T y$ (using the fact that $\hat{\beta} = (X^T X)^{-1} X^T y$)\)
\($= y^T X_j - (X X_j)^T (X^T X)^{-1} X^T y$\)
\($= y^T X_j - X_j^T (X^T X)^{-1} (X^T y)$\)
\(= y^T X_j - X_j^T \hat{y}$ (using the fact that $\hat{y} = X\hat{\beta}$)\)
\(= y^T X_j - y^T X_j = 0$.\)

To show that the vector of residuals, r, is orthogonal to every column of x, we need to show that the dot product between r and every column of x is equal to zero.
The residuals, r, can be calculated as r = y - Xb, where y is the vector of observed values, X is the design matrix, b is the vector of estimated coefficients, and the hat over X denotes the estimated values. Let's assume that xj is the jth column of the design matrix X, where j can be any integer between 1 and p. The dot product between r and xj is given by:
r'xj = (y - Xb)'xj
= y'xj - b'X'xj
= y'xj - b'ej (where ej is the jth column of the identity matrix)
= y'xj - b[j]
where b[j] is the jth element of the vector b. Since the least squares estimator b minimizes the sum of the squared residuals, we have X'r = 0, which means that the dot product between r and every column of X is equal to zero. Therefore, the vector of residuals, r, is orthogonal to every column of x.

What is the slope of the line represented by the equation y = y equals 4 Over 5 x minus 3.x – 3?
Answer:
\(slope=\frac{4}{5}\)
Step-by-step explanation:
\(y=\frac{4}{5} x-3\)
This is written in slope-intercept form:
\(y=mx+b\)
m is the slope and b is the y-intercept. x and y are the corresponding points (x,y).
Therefore, the slope is \(\frac{4}{5}\).

which method represents a correct way to solve the equation 2(t−5)=48?
The solution to the equation 2(t - 5) = 48 is t = 29.
To solve the equation 2(t - 5) = 48, we can use the following steps:
Distribute the 2 to the terms inside the parentheses:
2t - 10 = 48
Add 10 to both sides of the equation to isolate the variable term:
2t = 58
Divide both sides of the equation by 2 to solve for t:
