95% of the time confidence intervals like this capture the true average time between a felony.
The average of the true ranges throughout the given period is known as the average true range (ATR). ATR calculates volatility by accounting for any gaps in price movement. 14 periods, which can be intraday, daily, weekly, or monthly, are typically used in the ATR calculation. Utilize a shorter average, such as 2 to 10 periods, to gauge recent volatility. Use 20 to 50 periods for volatility over longer time spans.

The image of the polygon after a reflection in the line y=x is having vertices at A'(-3, 6), B'(-2, 1) and C'(1, 4) as shown in the diagram attached.
What is a reflection?A reflection is a sort of transformation that creates a new shape by flipping a shape, called the preimage, across a line, called the line of reflection (called the image). You may imagine what would occur if the form were turned over the line to graph a reflection.
A reflection is a type of transformation that involves flipping a shape, known as the preimage, over a line, known as the line of reflection, to produce a new shape (called the image).
You can picture what would happen if you flipped the form over the line in order to graph a reflection.
If a point A(x, y) is reflected about the line y = x,
the new point would be at A'(y, x)
Given the polygon with vertices at A(6, -3), B(1, -2) and C(4, 1).
The image of the polygon after a reflection in the line y=x has vertices at:
A'(-3, 6), B'(-2, 1) and C'(1, 4)
The image of the polygon is attached.

Sam and Liam raced up and then back down a hill. Sam's average speed up the hill
was 1 mph, and his average speed down the hill was 9 mph. Liam ran up the hill
and down the hill at 2 mph. If the trail from the bottom to the top of the hill is 1
mile long, how much time did it take each boy to finish? Who was the winner?
Using the speed formula, we know that Liam finished in 1 hour as opposed to Sam's 1/ 19 hours, earning him the victory.
What is speed?Speed is calculated as follows: speed = distance * time.
Knowing the units for distance and time is necessary to calculate the units for speed.
The units will be in meters per second (m/s) in this example since the distance is measured in meters (m) and the time is measured in seconds (s).
So, the speed formula is:
Speed = Distance/Time
Taking time for the subject:
Time = distance/Speed
Now, Sam:
Time spent ascending the hill = 1/1 = 1 hour
Time spent descending the hill = 1/9 hours
Sam spent 1 1/the9 total minutes climbing and descending the hill.
Now, Lian:
Time spent ascending the hill = 1/2 hours
Time spent descending the hill = 1/2 hour
Total time spent ascending and descending the hill = 1/2 + 1/2 = 1 hour
Sam, therefore, took 1/9 hour longer than Liam.
Therefore, using the speed formula, we know that Liam finished in 1 hour as opposed to Sam's 1/ 19 hours, earning him victory.

-
19 qtL
(Type an integer or decimal rounded to the nearest tenth as needed.)
The equivalent measure of 19 quarts is either 608 fluid ounces or 18.094 liters.
What is the equivalent measure?
In mathematics, and more specifically in measure theory, equivalence refers to the idea that two measures are qualitatively similar. The two measures specifically agree on which events have measure zero.
The unit "qt" stands for quart, which is a unit of volume.
It is equal to 32 fluid ounces or 0.946 liters.
Therefore, 19 quarts is equal to 19 * 32 = 1932= 608 fluid ounces,
or 19 * 0.946 = 190.946 =18.094 liters.
Hence, the equivalent measure of 19 quarts is either 608 fluid ounces or 18.094 liters.

The inequality is less than the quadratic function with zero -7 and 1 and includes the point (2,27/2) quadratic function is
y < 3/2 x² + 9 x - 21/2How to show the inequality requiredThe problem seeks the inequality that will be less than the quadratic function with zero -7 and 1 and includes the point (2, 27/2).
Therefore the quadratic function should have zeros at -7 and 1
Substituting the point (2, 27/2) to the quadratic function to check the one that gives the points shows that
3/2 x² + 9 x - 21/2 at x = 2
3/2 * 2² + 9 * 2 - 21/2

If in a recent poll, 280 people were asked if they liked dogs, and 42% said they did. the margin of error of this poll, at the 90% confidence level is 0.05.
How to find the margin of error?Sample proportion =42%(phat)
Sample size =280
Standard error = √(0.42×( 1- 0.42)/280)
Standard error = √(0.42×(.58)/280)
Standard error =0.029
Hence,
Margin of error = z-critical for 90% confidence level× Standard error
Zα/2 = 1.645 for 90% confidence

Find two positive numbers whose difference is 11 and whose product is 1692.
The positive numbers are 36 and 47.
What is a positive number?
Any positive number is one that is higher than zero.
A number can be zero, negative, or positive. Zero has no positive or bad aspects. The most frequent positive numbers in daily life include 34, 9.22, and other examples such as these. They are typically depicted on a number line to the right of zero, increasing bigger as you move to the right.
Assume that the positive numbers be x and y.
Given that the difference x and y is 11.
Therefore x - y = 11
x = y + 11 ....(i)
The product of the numbers is 1692.
xy = 1692 .....(ii)
Putting x = y - 11 in equation (ii):
(y + 11)y = 1692
y² +11y = 1692
y² +11y - 1692 = 0
y² +47y - 36y - 1692 = 0
y(y + 47) - 36(y+47) = 0
(y + 47) (y-36)=0

Rectangular prism 1:
l = 10 in.
w = 0.5 ft. = 6 in.
h = 4 + 7 = 11 in.
Surface area = 2*(6*10 + 11*10 + 11*6) = 472 in.²
