Answer:

I am 100% confident in my calculations. I'm not 100% sure about interpreting. Sorry I can't be of more help.

Part A:

Median: 4.5

IQR: 3.5

Mode: 6

I think the median/IQR is a better measure of center and variability because the range of data is so big (10 - 0 = 10), and the data skews to the right with the 6s.

Part B:

I would say no. It is the one that occurs most frequently, but there are many more times she rides less than 6, which is why the median is 4.5

Step-by-step explanation:

Mean: 4.714

MAD: 2.43

Median: 4.5

IQR: 3.5

Mode: 6

the number set in order:

0, 2, 2, 2.5, 2.5, 3, 4, 5, 6, 6, 6, 8, 9, 10

The median (middle number) is two numbers: 4 and 5, so the median is 4.5

The first quartile/Q1 (middle of the bottom half of data) is 2.5, the third quartile/Q3 (middle of the top half of data) is 6. So the IQR (interquartile range) is 6 - 2.5 = 3.5

The mean is the sum of the numbers divided by the quantity of the numbers, so 66/14 = 4.714

the mean absolute deviation is found by calculating the mean, and then finding the absolute value of the difference between each number of the set and the mean...then adding those together and finding the mean of that set. Labor intensive, but that's 34/14 = 2.42857143

What are the zeros of the function f(x) = x4 − x2 − 2?

goblinko [34]

Answer:

x = ± $\sqrt{2}$ , x = ± i

Step-by-step explanation:

f(x) = $x^{4}$ - x² - 2

to find the zeros , equate f(x) to zero , that is

$x^{4}$ - x² - 2 = 0

using the substitution u = x² , then

u² - u - 2 = 0 ← in standard form

(u - 2)(u + 1) = 0 ← in factored form

equate each factor to zero and solve for u

u - 2 = 0 ⇒ u = 2

u + 1 = 0 ⇒ u = - 1

convert u back into terms of x

x² = 2 ( take square root of both sides )

x = ± $\sqrt{2}$

x² = - 1 ( take square root of both sides )

x = ± $\sqrt{-1}$ = ± i

HURRY!!!When are two triangles said to be in perspective?

Readme [11.4K]

1. A
Two triangles are said to be in perspective (or as some would call it, homologous) from a point if their corresponding vertices form three lines that intersect in that single point (called a colinear point). Desargues' theorem asserts that if two triangles are in perspective from a point, then they are also perspective from a line (called the perspectrix); for this reason perspective triangles are also calles coplanar triangles.

2. B (13)
The series of numbers shown in the question is known as the Fibonacci Sequence. The next number in the sequence is found by finding the sum of the two numbers that precede it.

1 = 0+1
2 = 1 + 1
3 = 1 + 2
5 = 3 + 2
8 = 5 + 3

Next number is 13 (8 + 5)
