Which measure is always the 50th percentile?
mean
median
upper quartile

Answers

The measure that always represents the 50th percentile is the median. It is the middle value when data is sorted and is robust to outliers, unlike the mean.

The measure that always represents the 50th percentile in a dataset is the median. The median is the middle value in a dataset when it is ordered from smallest to largest. It divides the data into two equal halves, with half of the values falling below it and half above it.

Unlike the mean, which is the average of all values and can be influenced by extreme outliers, the median is robust to outliers because it solely depends on the middle value. This makes it a better measure of central tendency when dealing with skewed or non-normally distributed data.

On the other hand, the upper quartile, also known as the third quartile, represents the 75th percentile. It divides the data into the upper 25% and lower 75%. The mean is the average of all values in the dataset and does not necessarily correspond to any specific percentile.

In summary, the median always corresponds to the 50th percentile and is a valuable measure for understanding the central tendency of a dataset, especially when dealing with skewed data or outliers, while the mean and upper quartile represent different points in the data distribution.

Simplify the given equation. 5x + 2(x - 3) = -2(x - 1)

Answers

on the left side, distribute the 2 to x and -3 so the left side should look like 5x+2x-6.

on the right, distribute the -2 to x and -1 so the right side should look like -2x+2.

combine like terms on the left to get 7x-6=-2x+2

add -2x from the right side to the left side to make the equation 9x-6=2 now it's a two step equation.
add 6 to 2 to get 9x=8. divide by 9 and x=8/9.

Find the real or imaginary solutions of the equation by factoring. x^4-8x^2=-16

Answers

ANSWER
$x=2$ or $x=-2$
EXPLANATION

The given equation is
${x}^(4) - 8 {x}^(2) = - 16.$

We set everything equal to zero to obtain,

${x}^(4) - 8 {x}^(2) + 16 = 0$

We rewrite the leading term to obtain,

${( {x}^(2) )}^(2) - 8( {x}^(2)) + 16 = 0$

This has now become a quadratic equation in
${x}^(2)$

We split the middle term to get,

${( {x}^(2) )}^(2) - 4 {x}^(2)- 4x^2+ 16 = 0$

We factor to get,

${x}^(2) (x^2-4)-4( {x}^(2)-4) = 0$

We factor further to get,

$( {x}^(2) -4)(x^2-4)= 0$

This gives

$( x-2)(x+2)(x-2)(x+2)= 0$

$( x-2)^2(x+2)^2= 0$

$x=2$ or $x=-2$
