What is the median of the data values less than the median called?

ivann1987 [24]

A quartile is a type of quantile. The first quartile (Q1) is defined as the middle number between the smallest number and themedian of the data set. The second quartile (Q2) is themedian of the data. The third quartile (Q3) is the middle valuebetween the median and the highest value of the data set.

HELP FAST PLEASE!!!

Alisiya [41]

Answer:

$y = -0.75x + 9.5$

Step-by-step explanation:

Equation of a circle is given as :

$(x-a)^{2} + (y-b)^2 = r^{2} \\(x-6)^{2} + (y-5)^2 = 4^{2}\\x^{2} - 12x + 36 + y^{2} -10y + 25 = 16\\x^{2} - 12x + y^{2} -10y + 45 = 0\\$

Take the derivative of the above with respect to x

$2x - 12 + 2y dy/dx - 10 dy/dy = 0\\\frac{dx}{dy} = \frac{6 - x}{y-5} \\At (2,8) dy/dx = (6-2)/(8-5) = 4/3\\dy/dx = 4/3\\The slope of the tangent to the circle, m = \frac{-1}{dy/dx} \\m = \frac{-1}{4/3}\\m= -0.75$

The equation of the tangent is given by :

$y - y_{1} = m(x - x_{1})\\ y - 8 = -0.75(x - 2)\\y - 8 = -0.75x + 1.5\\y = -0.75x + 9.5$

The cardinal number of {208,209,210,211,....,1007} is

levacccp [35]

Answer:

$\large \boxed{800}$

Step-by-step explanation:

A cardinal number is the number of distinct elements in a finite set.

Your set consists the integers from 208 to 1007.

Each element is 1 more than the preceding element, so it represents an arithmetic sequence with distinct elements.

The formula for the nth term in an arithmetic sequence is

aₙ = a₁ + (n - 1)d, where

a₁ = the first element of the sequence

n = the common difference between successive terms

In your sequence,

a₁ = 208 and d = 1

To figure out how many elements are in the set, set aₙ to 1007 — the last member — and solve for n.

$\begin{array}{rcl}a_{n} & = & a_{1} + (n - 1)d\\1007 & = & 208 + (n - 1) \times 1\\1007 & = &208 + n - 1\\1007 & = &207 + n\\n & = & \mathbf{800}\\\end{array}\\\text{The cardinal number is $\large \boxed{\mathbf{800}}$}$
