Therefore, the maximum value of 17 is not considered an outlier as it falls within the upper limit.

what is  Median?

The median is a statistical measure that represents the central value of a dataset.

To calculate the upper limit for outliers, we can use the interquartile range (IQR) and the formula:

Upper Limit = Q3 + 1.5 * IQR

where Q3 is the third quartile, and IQR is the interquartile range.

First, we need to find the values for Q1, Q2 (median), and Q3:

1, 6, 6, 6, 7, 7, 8, 9, 13, 10, 17

Arranging the data in order:

1, 6, 6, 6, 7, 7, 8, 9, 10, 13, 17

The median is the middle value. Since there are 11 values, the median is the average of the 6th and 7th values:

Median = (7 + 8) / 2 = 7.5

To find Q1 and Q3, we need to find the medians of the lower and upper halves of the data, respectively:

Lower half: 1, 6, 6, 6, 7

Upper half: 8, 9, 10, 13, 17

Q1 is the median of the lower half, which is 6.

Q3 is the median of the upper half, which is 10.

Next, we can calculate the interquartile range:

IQR = Q3 - Q1 = 10 - 6 = 4

Finally, we can calculate the upper limit for outliers:

Upper Limit = Q3 + 1.5 * IQR = 10 + 1.5 * 4 = 16

Any value above 16 can be considered a potential outlier on the high end of the data.

Therefore, the maximum value of 17 is not considered an outlier as it falls within the upper limit.

Answer:

Triangle XYZ is shifted 9 units to the right, then 4 units down.

The correct answer is:

x + 12 ≤ 5 − y ≤ 2(x − 3)

Explanation:

From the given inequalities:

x + 12 ≤ 5 − y ... (1)

5 − y ≤ 2(x − 3) ... (2)

We can see that 5 - y is common in both inequalities. We can isolate this term by subtracting 5 from both sides of (1) and (2):

x + 7 ≤ -y ... (3)

-y ≤ 2(x - 8) ... (4)

Multiplying (3) by -1, we get:

y - 7 ≥ x ... (5)

Substituting this value of x in (4), we get:

y - 7 ≤ -2(7 - y)

y - 7 ≤ -14 + 2y

y ≤ 7

Substituting this value of y in (5), we get:

0 ≤ x + 7 ≤ 14

Subtracting 7 from all sides, we get:

-7 ≤ x ≤ 7

Therefore, the statement x + 12 ≤ 5 − y ≤ 2(x − 3) is not true, but the statement -7 ≤ x ≤ 7 is true.

If all three of them together have a total of 520 kroner then bill would have 205 kroner

amounts of money that Alan, Bill, and Cassie have:

Let A be the amount of money that Alan has.

Let B be the amount of money that Bill has.

Let C be the amount of money that Cassie has.

From the problem, we know that:

A + B = 250 (equation 1)

B + C = 475 (equation 2)

A + B + C = 520 (equation 3)

We want to solve for B, the amount of money that Bill has.

One way to do this is to use equation 1 to solve for A in terms of B:

A = 250 - B

We can then substitute this expression for A into equations 2 and 3:

(250 - B) + B + C = 520

Simplifying this equation, we get:

C = 270

Substituting this value of C into equation 2, we get:

B + 270 = 475

Solving for B, we get:

B = 205

Therefore, Bill has 205 kroner.

To calculate the distance between two points on a coordinate plane, the distance formula can be applied which is given as:

d = [tex]\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex].

Given the two points lie on the coordinate plane as the following coordinates:

N = (-8, 9)

C = (-4, 6)

Therefore, we will have:

d = √[(−4 − (−8))² + (6−9)²]

The expression for the nth term of the sequence is,  Tn = 3n^2 - 7n - 1

To find an expression for the nth term of a quadratic sequence, we need to find a quadratic function that describes the sequence.

Let the nth term of the sequence be denoted by Tn. We can use the method of finite differences to determine the degree of the quadratic function that describes the sequence.

The first differences between the terms are 6, 10, 14, 18, 22. The second differences between these first differences are all equal to 4. This tells us that the sequence is quadratic, since the second differences are constant.

To find the quadratic function that describes the sequence, we can use the formula for the nth term of a quadratic sequence,

Tn = an^2 + bn + c

where a, b, and c are constants to be determined.

We can use the first three terms of the sequence to form a system of three equations,

T1 = a + b + c = -5

T2 = 4a + 2b + c = 1

T3 = 9a + 3b + c = 11

Solving this system of equations, we get:

a = 3

b = -7

c = -1

Therefore, the expression for the nth term of the sequence is

Tn = 3n^2 - 7n - 1

Answer:

To find the slope of the line through point B and perpendicular to line k, we need to first find the slope of line k.

If we have the equation of line k in slope-intercept form, y = mx + b, then the slope of line k is simply the coefficient of x, which is m.

Assuming we don't have the equation of line k, we can find its slope by using the slope formula, which is:

m = (y2 - y1)/(x2 - x1)

where (x1, y1) and (x2, y2) are two points on line k.

Let's say line k passes through points P and Q. Then we can write the slope of line k as:

m = (yQ - yP)/(xQ - xP)

Now, we want to find the slope of the line through point B and perpendicular to line k. We know that the product of the slopes of two perpendicular lines is -1. That is:

m1 * m2 = -1

where m1 is the slope of line k, and m2 is the slope of the line through point B and perpendicular to line k.

Therefore, we can write:

m2 = -1/m1

So we just need to find the slope of line k, and then we can use this formula to find the slope of the line through point B and perpendicular to line k.

Once we have the slope of the line through point B, we can write its equation in point-slope form:

y - yB = m2(x - xB)

where (xB, yB) is the point B.

The value of x is 10 and the trapezoid has two base angles with measure 40 degrees and two non-base angles with measure 140 degrees.

What is the congruent angle?

When two parallel lines are cut by a transversal, the angles that are on the same side of the transversal and in matching corners will be congruent.

In an isosceles trapezoid, the base angles (the angles opposite the parallel sides) are congruent. Let's call each of these angles "a". Then, we have:

a = 3x + 10 (from one of the congruent angles)

a = 5x - 10 (from the other congruent angle)

Setting these two expressions equal to each other, we get:

3x + 10 = 5x - 10

Solving for x, we get:

2x = 20

x = 10

Now that we know the value of x, we can substitute it back into either of the expressions for "a" to find the measure of each base angle:

a = 3x + 10 = 3(10) + 10 = 40

Therefore, each base angle of the trapezoid has measure 40 degrees.

The other two angles of the trapezoid are the non-base angles (the angles adjacent to the parallel sides).

These angles are supplementary to the base angles, so each non-base angle has measure:

180 - 40 = 140

Therefore, the value of x is 10 and the trapezoid has two base angles with measure 40 degrees and two non-base angles with measure 140 degrees.

Approximately 491351% of the annual moisture at an altitude of 6000 feet falls as snow.

According to the given function, the percent of annual snowfall at an altitude of h feet is given by p(h) = 82 in (h) - 649. To approximate the amount of snow at the altitudes of 3000 feet and 6000 feet, we can simply plug these values into the function and solve for p(h).

At an altitude of 3000 feet, we have:

p(3000) = 82 in (3000) - 649

p(3000) = 246000 - 649

p(3000) = 245351

Therefore, approximately 245351% of the annual moisture at an altitude of 3000 feet falls as snow.

Similarly, at an altitude of 6000 feet, we have:

p(6000) = 82 in (6000) - 649

p(6000) = 492000 - 649

p(6000) = 491351

Therefore, approximately 491351% of the annual moisture at an altitude of 6000 feet falls as snow.

It's important to note that these values represent percentages and not the actual amount of snowfall in inches. To convert these percentages to the actual amount of snowfall, we would need to know the total annual moisture at each altitude. Nonetheless, we can use the given function to approximate the percentage of snowfall at different altitudes in the mountain range of California.

Length is one of the fundamental physical quantities, and is used in various fields including mathematics, physics, engineering, and construction.
