Write all number from least to greatest.

52 64 67 68 75 75 78 78 88 90

In the middle 75 and 75 were left. Median =(75+75)/2 = 75

Answer : 75.

To find the median of a data set order all the numbers from least to greatest, then find the number in the middle. If there are two numbers in the middle find the mean of the two numbers.

90 52 78 64 67 88 68 75 75 78 ← given

52 64 67 68 75 75 78 78 88 90 ← ordered l to g

75 and 75 are the two numbers in the middle, and since they are the same that means 75 is our median.

D) 75 is your answer.

Can anybody help me with 1 and 2

1) $x \geq 96$
2) $x\ \textless \ 38$

Here, the variable $x$ can assume any value, and usually an inequality presented like this has $x$ as a stand-in for all real numbers. If we really wanted to make that fact clear, we could write the two inequalities like this:

$x \geq 96, x\in\mathbb{R}\\ x\ \textless \ 38, x\in\mathbb{R}$

Formally, you'd read $x\in\mathbb{R}$ as " $x$ is an element of the set of real numbers," which is a fancy way of saying that $x$ can be any real number.
